• 7:23am
• Bugscope Team hi there, welcome to bugscope!
• Teacher Good morning. I have just logged on in preparation for my third grade students to come to class at 8:30 eastern time, the we will switch classes at 9:15 and have another group for 40 minutes. Ok?
• Bugscope Team that sounds just fine
• Bugscope Team did anyone get back to you about the compatibility test results?
• Teacher May I practice until they arrive. Yes it seems that it will be fine, maybe just slow, but mornings are always better than afternoon for internet connections
• Bugscope Team sure, i just unlocked the session, you should see controls on the right side now

• Bugscope Team try using click to center instead
• Bugscope Team also, you can click on any preset to go there
• Bugscope Team and if you need to focus, we can do that for you, click to drive and focus take up more network bandwidth, so you'll see some lag if you use those functions

• Teacher Can you drive for us too?
• Bugscope Team sure, i can do that
• 7:28am
• Bugscope Team are you going to have the students login themselves, or are you going to type all the questions yourself?

• Teacher I would like for them to login and do it themselves if you think that would be ok.
• Bugscope Team sure, that's the best really. also then, i would try to limit the logins to less than 10
• Bugscope Team if the network is slow, having many logins will slow things down as well
• Bugscope Team please feel free to ask any questions you or the students may have
• Bugscope Team this is a beetle head
• Bugscope Team hey alex
• Teacher ok I will pair them up at computers, there are just 14 in each class and i have a projector that will be showing a large image on the wall for all to see. Can we do an intro together? I would type a hello and ask for any tips for the class when they arrive.
• Bugscope Team sounds great mrs vignale, we are ready anytime

• 7:33am

• Bugscope Team this is a caterpillar

• 7:38am

• Bugscope Team good morning class, welcome to bugscope!

• Bugscope Team cate is an electron microscopist, and i'm a systems administrator. but we have both been doing bugscope for years, and can tell you lots about the insects you are seeing
• Bugscope Team please go ahead and ask us any questions you have about what you are seeing

• Bugscope Team welcome to bugscope students!
• Student witch part is this
  Bugscope Team these are prolegs on a caterpillar
• Student how do you guys know all of these stuff
  Bugscope Team we learn by doing really. Sometimes we have an entomologist log in and help us with what we dont know
• Student can we see the proboscis
• Student What is this?
  Bugscope Team these are hooks on the caterpillar that help it stay on leaves and such. They hook themselves in
• Bugscope Team if you all did this enough youd know a lot about insects too, even if you arent a bug expert

• 7:43am
• Bugscope Team many insects have common parts though: exoskeletons, compound eyes, setae (hair like things), etc.
• Student that is a big micriscope
• Student this is cool
• Student what is this picture
• Student it looks like a rib right there
• Bugscope Team i believe the term for them is crochettes

• Student oh
• Student i wonder what this isi think it's bones
  Bugscope Team well, not bones, but they do look like bones don't they. insects don't have bones like we do. instead they have a hard outer shell called an exoskeleton
• Student bugs are weird
• Bugscope Team caterpillars are very different from their adult counterpart. It's not always that way. Larvae of insects can look a lot like their adult form
• Student What type of caterpillar is this?
  Bugscope Team not sure. it was kind of smooth, so definitely not a wooly bear caterpillar
• Bugscope Team caterpillars dont have a proboscis like a butterfly or moth, they have jaws
• Student what are crochettes
  Bugscope Team they use those hooks attached to ther legs to help stabilize themselves while they are on plants
• Student what are the bony things
  Bugscope Team those are the hooks that help the caterpillar to hold onto things, like leaves and plants
• Student We rased caterpillers in the fall
• Student are these bones
• Student can we see spericles
  Bugscope Team i tried finding a spiracle this morning, but i couldn't find one, sorry. maybe we'll run into one later. spiracles are very cool, that is how insects breathe
• Bugscope Team although these look like bones, they are not bones at all. insects don't have bones
• Student Wow
• Student can we see another body parts?
• Bugscope Team some insects have special pads of hair by their legs that help them stick onto vertical surfaces, these might help acheive the same purpose
• Student can we see a simple eyes on a caterpiller

• Bugscope Team okay, now we are moving to a beetle. this is a compound eye on a bettle
• Student Whats a proleg?
  Bugscope Team caterpillars have segments of legs that come in pairs, they are called prolegs
• Bugscope Team sure, we'll get to the simple eyes in a second
• Student Cool!!!
• Student thankes for swiching alex
• Student what are those thorn things.
• Student what are the spikes
  Bugscope Team those are insect hairs that we call setae (see-tee). They help the insect know what's going on around it in its environment
• 7:48am
• Student can we get closer
• Student can we get any closer
• Bugscope Team those spikes or hairs are called setae (pronounced see-tee)
• Student COOL!

• Student This scary!!!!
• Bugscope Team now we are at 1268x magnification
• Student COOL!!!!!!
• Bugscope Team this is its compound eye
• Student does it have hair?

• Student what are those bumps
  Bugscope Team those are the individual facets, lens, of a compound eye

• Student look at the bubbles

• Student CAN WE GO CLOSER?
• Student what is this ?

• Bugscope Team those spikes are setae, those are very important to insects
• Student GO CLOSER MUCH CLOSER PLEASE
• Student How close is this?
• Student cooooooooooooooooooooooooooooool!
• Bugscope Team this insect has a bit of juju on it. Some liquid must have gotten on it and dried
• Student Is this a bettle?
• Bugscope Team since insects have a hard outer shell, an exoskeleton, and that shell can't feel anything, they need some way to feel things. that's where the setae come in
• Student what is juju
• Bugscope Team the setae stick through the exoskeleton, attach to nerves underneath
• Student COOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOL ITS HAIRY
  Bugscope Team yes insects are a lot hairier then they eem
• Bugscope Team yes, this is a beetle
• Student I can see dirt
  Bugscope Team yep, dirt and grime, we call it juju

• Bugscope Team seem
• Student What is that dirt stuff?
  Bugscope Team it's just dirt
• Student What are the bumps on the eye
  Bugscope Team those are the individual components of the compound eye. think of them as a different lens. we call each part of their eye an ommatidium
• Student IS THERE A LITTLE BUGS ON THE HAIR
  Bugscope Team i'm going to go find out
• Student how do bugs have all these detailed gross parts
• Bugscope Team well move to the bumps on the eye in a sec

• Teacher can you choose another for us?

• Bugscope Team flying insects have tons of ommatidium
• Bugscope Team sure, i'm going to focus on the little piece of dirt that alyssa wanted to see

• Student got any info
• Student are there bugs on there hair
• Bugscope Team hey alyssa and jacod, this is that piece of dirt, it looks like dirt, not a bug, sorry
• Student closer

• Student Does juju appear often?

• Student closer

• 7:53am
• Bugscope Team this is 20,000x magnification!!!
• Student that looks like a sword
• Student What is that?
• Bugscope Team this scope can go up to 600,000x mag, but for these bugs, we don't go much past 40,000x
• Student Go out so i can see the eye
• Bugscope Team that sword looking thing is a sensory setae, they help it to sense things in the world

• Student please!!!

• Bugscope Team okay, now we are back to the compound eye
• Student thank you
• Student CAN YOU GO NEXT
• Bugscope Team each bump in the eye is called an ommatidium, as cate said
• Student this is HUGE!!!!!!!!!!!!!!!!
• Bugscope Team each ommatidia has a lens in it
• Student can we see the grasshper head
• Bugscope Team yeah, insects have very cool compound eyes
• Student Can we see the but?
• Student what is an ommatidium
  Bugscope Team they are individual lenses of the eye
• Bugscope Team the difference here though, is that the insect compound eye can't move the lens like humans can
• Student can we see something else?
• Bugscope Team flies, wasps, and bees have really big compound eyes that make it impossible ot count all the ommatidia
• Bugscope Team each lens is fixed, but since there are hundreds of lenses, they can see a wide angle
• Student can we see the grasshoper head
• Student may we see the thrax
• Student can we see the thorax
• Bugscope Team okay, we are moving to the grasshopper head now

• Student We meen butt
• Bugscope Team yeah, insects have a butt area, but it's called an abdomen... :)
• Student CLOSER
• Bugscope Team check out the compound eye on the left, and the antenna above it
• Bugscope Team to the right are the mouht parts, with some palps
• Student closer, please
• Student Are those teeth?
• Student are those hairs on their head
• Student can we see it :)
• 7:58am
• Student LOSER
• Student COOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOL ?
• Student CLOSER
• Student what are we looking at
• Student what is this
• Student it looks like the moon
• Bugscope Team setae help insects to sense things
• Student what are we looking at
• Student SORRY I MENT CLOSER
• Bugscope Team setae can be mechanosensory, sensing movement. or they can be chemosensory, and sense smells and tasts
• Student What is this?
• Bugscope Team setae are VERY important to insects
• Bugscope Team this is the grasshopper
• Student COOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOL!!!!!!!!!!!!!
• Bugscope Team this is now the antenna
• Student sweet
• Bugscope Team this is a shaft on the antenna
• Student Is this the leg ?
• Student tHIS SCARY
• Student it looks like a tree
• Student CLOSER CLOSER CLOSER!
• Student Are there sete on the antena?
• Student what are the differences between a grasshopper and a cricket?
• Bugscope Team we think these are brochosomes!!!!
• Student What is that , it look like snake skin
• Student howbig is this
  Bugscope Team well, if you look at the scale bar in the lower left, you'll see a ruler
• Student what is a brochosome?
  Bugscope Team a brochosome is a tiny waxy particle like an open soccer ball that is produced by leafhoppers but ends up often on other insects
• Student it looks like an eye
• Student Is it a baby?
• Bugscope Team this antenna part is probably chemosensory, in that is can sense smells (ie, chmicals)
• Student is that a egg
• Student What is scott doing
  Bugscope Team scott is controlling the scope now, finding some interesting things to look at for you guys!
• Student can we see the mandibles?
• Student whos your partner or do you not have one
• Bugscope Team brochosomes may be used to help keep eggs from drying out, but we are not sure of their purpose
• Student THIS IS HUGE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
• Student what is that black thing
• Bugscope Team a um (in the scale bar) is a micron. one micron = one millionth of a meter
• Student can we see the flea head?
• Student Can we see the head again

• Bugscope Team brochosomes were first discovered in 1952, when someone put a leafhopper in an electron microscope, much like what you are looking at noe
• Student can we see the flea head
• Bugscope Team this is the head of the flea
• 8:03am
• Student :) :)
• Bugscope Team this is a flea
• Student it looks like a dinsor
• Student is this a flea head?
• Bugscope Team fleas also have compound eyes
• Bugscope Team yes, this is a flea head
• Student what is the teeth things
  Bugscope Team that is part of the cuticle on the face; we are not sure
• Bugscope Team the eyespot is to the right, and the mouthparts are to the left; it is facing north
• Student WHOA
• Student are those teth cause they look scary
• Student it's scary
• Student Eyes
• Student i ment teeth
• Student NOW I THINK THAT FLEAS ARE ALL OVER ME
• Bugscope Team heh, well, fleas are a part of life...
• Student It looks wierd.
• Student what are those circles in back
  Bugscope Team those are holes in the stick tape that we put the bugs on
• Student My dog and Jafars cat hates them.
• Student how is this possible?
  Bugscope Team how is what part possible?
• Student we know, but still
• Student i hope i dont have a flea on me cuse they eat your head
• Student cool
• Bugscope Team this is one of the biting parts of the flea
• Student Is this an eye?
• Student what is that
• Student scary
• Bugscope Team this is part of the flea that cuts into your skin
• Student gross
• Student what is the leafy stuff
• Bugscope Team see how it looks like a chainsaw blade, in a way?
• Student it looks like a sting ray.
  Bugscope Team yes!
• Student can we see the mouth?
  Bugscope Team i don't think we can see the mouth from this angle
• Student which part does the flea suck blood with?
  Bugscope Team the part we saw -- one of the laciniae -- cuts into your skin. there must also be a siphon tube of sorts but we did not see it here
• Student it looks like coral
• Student where is its eye
• Student Back there
• Student Ok :)
• 8:08am
• Student can we see a nother bug
• Student isiy looks like a crab leg
• Student It looks lik a crab
• Bugscope Team see the large powerful legs
• Student is that a flea
  Bugscope Team yep, that was a flea

• Student wow

• Student Whats that?
• Bugscope Team these are palps on a beetle
• Student what is that
• Bugscope Team palps help taste and smell food that the beetle eats
• Student what are palps
• Student what is a p
• Bugscope Team palps can also shovel food into the mouth if need be
• Student are they on the feet
• Student are those the legs
• Bugscope Team palps are little sensory things that are around the mouth, they help taste food
• Student where is the palp
• Student are we on we on the feet
• Student oit looks like a a hand
• Student no o
• Student change it its scaring us
• Bugscope Team yes! you can see some claws now, scott is going to focus on them
• Student can we see a closer view of th mouth
• Bugscope Team BOOOOO!!!!!!!!!!! (ha ha)
• Student thank you
• Student its time for us to go now thank you
• Bugscope Team this is a beetle claw
• Student Thanks!!!!!!!!!!!!!!!!
• Bugscope Team you all did great!!!
• Student thaks
• Student bye bye
• Student thaaaaNKS!!!!!!!!!!!!!!!!!!!!!!!!!!
• Student bye
• Student this was cool
• Bugscope Team Thanks!
• Student thanks have a grate day
• Bugscope Team you all did really well, you are budding little scientists
• 8:14am
• Bugscope Team mrs vignale, how are things going on your end, from here it seems like the kids are happy and learning
• Bugscope Team also, we are going to have to end the session right at 10AM (your time), as the scope is needed at that point by a researcher
• Bugscope Team however, keep in mind, all the chat and images are saved to your member page: http://bugscope.beckman.illinois.edu/members/2009-091, you can review the session anytime with your students
• Bugscope Team yeah
• 8:21am

• Student Hi the next group is logging in now and the last group left here totally jazzed!
• Bugscope Team welcome to bugcope!
• Student Hi!
• Student have u ever seen a cool dude bug?
  Bugscope Team here's one!
• Student how'd you get these
  Bugscope Team usually the school will send us insects to put in the scope, but we have a collection as well

• Student Hi
• Student cool!
• Student HI!
• Student what are we looking at
• Student what is this
• Bugscope Team this is a fruit fly
• Student heuoooooooooooooooooo
• Bugscope Team see its eyes?
• Student what are we looking at ?

• Student what is this
• Bugscope Team this is a fruit fly head
• Student what is this bug
• Bugscope Team the little things that look like blinders are the antennae
• Student can you zoom in
• Bugscope Team you can see it's huge compound eyes, and the stubby antenna on top
• Bugscope Team okay, we are zooming in on the compound eye now
• Student are those scales?
• Bugscope Team those bumps are the individual facets of the eye
• Bugscope Team each bump has a lens in it
• Bugscope Team you can see the individual ommatidia -- the facets of the eye
• Bugscope Team and you can see bristles in between most of them
• Student what are the spikes
• Student what are the spikes for
  Bugscope Team it is thought that those spikes help sense wind speed when flying, that helps the fruit fly to fly around better
• Student zoom in closer
• Student That cool
• Bugscope Team so, the fruit fly can see thousands of images with this compound eye, and the fly brain assembles all those images into one simple image for the little buggar
• Bugscope Team those bristles, or setae -- spikes -- help the fly gauge the speed of the wind and its direction
• Student Why is it called a Fruit Fly?
  Bugscope Team well, it likes to feed on decaying mold that grows on fruit
• 8:26am
• Student how close can u go?
• Student how did you get it this close?
• Student are the brisels sharp
• Student what are the bumps for?
  Bugscope Team the bumps are the facets of the eye -- individual lenses
• Student cool
• Student do u no what his skin's made of?
  Bugscope Team well, it's not skin, it's called an exoskeleton and it's made of chitin, like what your fingernails are made of
• Student how far can you zoom in
• Bugscope Team the fruit fly pukes on its food, and then sucks up that puke - it's a really royal lifeform!
• Student Wo that ieg looks cool
• Student What is that?
• Student Thats cool
• Student what's this
• Student intresting
• Student it looks like a inside of a pumpkin
• Student What is that cool looking bug
• Student are these legs?
• Bugscope Team ah cool, here's a claw
• Student Legs?
• Student It looks spikey
• Student Cool!
• Student where did u find this bug?
• Bugscope Team yeah, those spikes are the hairs (setae) again
• Student its like a crab
• Bugscope Team the setae re vital to all insects
• Student Claw?cool!
• Student is it spiky
• Student why do fruit flies have claws?
• Student Why are there claws?
  Bugscope Team well, insects need to grab onto things for survival, so most have claws of some sort
• Bugscope Team setae help insects to feel their environment. setae can sense movement, tastes, smells, temps, etc.
• Student zoom in as close as you can
• Bugscope Team claws are sort of like hands to us
• Student this claw loks lik a handcuff!
• Student Wo cool
• Student that is awesome!
• Student WOW!
• Bugscope Team there's a brochosome, on the left
• Student do they have 6 claws?
• Student how far can you zoom in
  Bugscope Team we can go farther, but soon it will not be so interesting
• Bugscope Team brochosomes are made by the leafhoppers
• Bugscope Team the scope can magnify 600,000x, but for these insects we don't go much past 40,000x
• Student what are leafhoppers?
• Bugscope Team notice the scale bar in the lower left: click on it
• Student What are those round things
  Bugscope Team those were the brochosomes
• Student what part of the bug is this?
• Student what is that?
• 8:31am
• Student what are leafhoppers
• Student what is that circle in the back round?
• Bugscope Team leafhoppers are plant pests
• Student Can we move to another sample...maybe the caterpillar
• Bugscope Team now we are going to another fruit fly
• Student what is it?
• Student look at the intenas
• Student oh
• Student is that a bug?
• Bugscope Team ah, we'll get to the caterpillar in a sec mrs vignale
• Student -can we c a clos up on the i?
• Bugscope Team this is a spiracle!!!!
• Bugscope Team this is how insects breathe
• Student WOW!
• Student AWESOME1
• Bugscope Team notice all the setae surrounding the spiracle, that's so dirt and juju doesn't fall into it
• Student is that a hairy eye?
  Bugscope Team no, that was a spiracle, a breathing hole
• Student Why is it so hairy?
• Student cool!!!!!
• Bugscope Team those hairs are vital, they help it to feel things
• Student It is fuzzy
• Student why isn't it in color
  Bugscope Team Its because we use electrons, which are much smaller than the wavelength of light
• Student is that all hair
• Student fuzzy
• Student What are those
• Student awsome!
• Student is that its skin?
• Student Is that its face
• Student can you put it i colar
• Student what is that?
• Bugscope Team insects have a hard outer shell, called an exoskeleton, and that exoskeleton can't feel anything. the hairs (setae) stick through the exoskeleton, to nerves underneath, and that's how they feel things
• Bugscope Team this is an antenna, a close up
• Student What are those
• Bugscope Team this is the antenna, up close
• Student why is it black and white
  Bugscope Team good question. this is an electron microscope. so we are using electrons to get the image, we are NOT using light. color is a property of the frequency of light, and since we are not using light, there is no color. but what we don't see in color, we make up for with amazing contrast and magnification
• Student what is this?
• Student What is that
• Student is that sharp
• Bugscope Team this is what the fruit uses to help it smell where fruit is
• Student What are the bumps for?
• Student what is it?
• Student is that a part of the antena
• Bugscope Team the setae and other projections are mostly chemosensory -- for sensing chemicals in the air
• Student why are there so many?
• Student is it possible to put it in color
  Bugscope Team yes, after the images are collected, one can do an elemental analysis of the image and color in based on that data. but we don't do that for bugscope
• Student can we c a diff bug?
• Student WHAT IS IT!?
• 8:36am
• Student what is that
• Student what are those little spots?
  Bugscope Team those are bumps in the tape we put the bugs on
• Bugscope Team we think this is a stonefly
• Student Thats a bug right
• Student wat is this?
• Student ?
• Bugscope Team this is a stonefly larva
• Student can we see a different bug?
• Student what is a stone fly?
• Student a stonefly?
• Bugscope Team a stonefly is an aquatic bug
• Student can we c a cenapeed?
• Bugscope Team we are going to the caterpillar now
• Student What is it laying on
• Bugscope Team wait, quick stop at the mayfly, another aquatic bug
• Student cool!!!
• Bugscope Team mayfly's and stonefly's both live in the water and feed on decaying plant matter
• Student what does aqactic bug
• Student What is that
• Bugscope Team it means it lives in/around the water
• Student can we c the i's
• Student an it swim?
• Student what is that
• Bugscope Team this is the eye of the armored mayfly larva
• Student it looks like durt
• Student what is that
• Student .
• Bugscope Team yeah, lots of juju on this eye
• Student What are those spikes
• Bugscope Team this is some kind of crystal on the eye... cool!
• Student is that the i
• Student IS that scum
• Bugscope Team that spiky thing is the crystal
• Student wHAT IS IT?!
• Student is that an a eye
• Bugscope Team the crystal must have bloomed on the eye while we kept the sample here
• Student tell us more about the crystal
• Student tell us about the crystal
• Bugscope Team this is an antenna
• Student how do they see with all that juju?
  Bugscope Team the juju was not all there when the mayfly was in the water
• Student wow
• Student is that an antena?
• Student tell us more about the crystal
• Student what is this
• Bugscope Team yep, this is an antenna
• Student What are those spikey things
  Bugscope Team more setae, used to sense things
• Student why are there holes
  Bugscope Team well, there are actually little setae sticking out of those holes
• Student how is juju pronounced
  Bugscope Team it is pronounced, jew-jew
• 8:42am
• Student can we c a centapeed
  Bugscope Team we don't have a centipede today, sorry
• Student what is juju?
  Bugscope Team that's our name for dirt or grime, or stuff we don't know what it is
• Student What is it?I mean the holes.
• Student !!!!!!!!!!!!!!!!!!
• Student what is this
• Student what is that
• Bugscope Team if you image is black or delayed, try refreshing. (F5)
• Student what is that stuff
• Student that is hairy!!!!!!!!!!!!!!!!
  Bugscope Team yes, or rather, setae-y
• Bugscope Team these are mouth parts of a mayfly...
• Student wat is t spiky stuf?
  Bugscope Team a lot of it is setae that help filter the water
• Student woah
• Student What are we looking at?
  Bugscope Team this is the mouth of the armored mayfly nymph
• Bugscope Team the spikes are setae, used to feel things, taste things
• Bugscope Team this is a mouth of a mayfly
• Student What is it
• Student how do you get so close?
  Bugscope Team this is an electron microscope, it uses electrons to get the image, so it can magnify very very small
• Student w hat part of the caterpiller are we looking -at

• Student can we move on
  Bugscope Team yes!
• Student nice zoom out!
• Student wat is this part"?
• Bugscope Team now we are going to the caterpillar
• Student thats cool
• Bugscope Team this is the head of the caterpillar
• Student what are those bumpy things on the head
  Bugscope Team those are the eyes, called stemmata
• Student yeah
• Student what is that!!!!!!!!
• Student what is that+
• Student is this the catapiler
  Bugscope Team yes it is the caterpillar
• Student zoom in!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
• Bugscope Team simple eyes
• Student wow
• Student can we lok at the mouth
• Student zoom
• Student that looks wierd
• Student is that a leaf
  Bugscope Team it is a scale from another insect -- a butterffly or moth
• Student Its bumpy
• Student whats this
• Student What is this?
• Student wat is the lef thi';[n
• 8:47am
• Student why is that leef shaped thing on it
  Bugscope Team it just stuck on there at some point -- it is a scale from a butterfly or moth -- the powdery soft stuff you feel when you rub one of the wings
• Bugscope Team the little oval things are bacteria
• Student is the bacteria bad
  Bugscope Team bacteria will eventually get on everything and cause things to decompose, so they are not really bad all of the time
• Student why is bacteria on it?
• Student how did u find thes?
• Bugscope Team well, bacteria grows on everything eventually
• Student why is there bactiera on the caterpillar
• Student Were do you find all these bugs
• Student is that the mouth
• Bugscope Team these are spinnerets
• Student is that an eye
• Student is that bump of the catapiler or did he get it from geting hurt?
  Bugscope Team he got hurt
• Bugscope Team many caterpillars can make silk, like spiders can
• Student ow
• Student wat els bugs mak silk?
• Student is there a way to keep bactiera from growing
  Bugscope Team well, there are, soup and water can do wonders
• 8:52am
• Student is that his mouth?
• Student what is that hole or is it a hole?
  Bugscope Team that is the entrance to the mouth
• Student when we studied caterpillars I never was that close
• Bugscope Team that's why it's good to wash your dirty hands, it will reduce bacteria
• Student may we see the prolegs
  Bugscope Team sure!
• Student closer into the i,please
• Student can you go inside
• Student WHat are those bups
• Student what is that?
• Student r thos th eegg
• Student we studied catapilers
• Bugscope Team this is a scale
• Student Whats that?
• Student Prolegs are cool
• Student what are the hears for?
  Bugscope Team the hairs are called setae, they help it feel things
• Student why is it all shriveled up?
  Bugscope Team when insects die they dry out and that can cause them to shrivel up
• Student OMG
• Student look at those claws
• Student are we inside it?
• Student can we go inside
• Student wat r the loopy thi
• Student is that a claw?
  Bugscope Team it is a claw, or a bunch of them, on the caterpillar proleg
• Bugscope Team these are called crochets
• Student OMG!
• Student r croches sharp
  Bugscope Team yes, they are
• Bugscope Team in addition to the six legs they already have, caterpillars often have a number of extra legs called prolegs
• Bugscope Team but they are very small too
• Student why are they so thin arent they suppposed to be thick so they can grab better
• Student may we see the grasshopper head?
• Bugscope Team prolegs usually come in pairs too
• Student cool can we see a different part of the body
• Bugscope Team we are moving to the grasshopper head now

• Student can they hurt humans?
  Bugscope Team no, not really
• Student did he get hurt
  Bugscope Team he lost one of his antennae but that may have been after he died
• Student what is the bump?
  Bugscope Team that's the compound eye
• 8:57am
• Bugscope Team notice that the compound eye is very smooth
• Student whats the thing stiking out of the head
  Bugscope Team the antenna
• Student are thoose bubbles in the backround?
  Bugscope Team those are bumps in the tape we put the bugs on
• Student can we c a closup of the mouth;)
• Student How did it die?
