- Guest hi every one
- Bugscope Team hi aditi
- Guest if i am not answering it is because my computer won't show the transcript
- Bugscope Team you may need to change your screen resolution
- Bugscope Team minimum screen res for bugscope is 1024x768
- Guest i've tryed refreshing
Bugscope Team did you try to increase your screen resolution
- Guest how do you do that
Bugscope Team or maximize your browser window
Bugscope Team to increase your screen resolution: right click on the desktop, select properties, click on the settings tab, then increase your screen res to 1024x768
- Guest it worked
- 3:30pm
- Guest well i don't need to know that at this time because I can see now
- Guest what are we looking at
Bugscope Team these are worms, the school today wanted to see worms
- Guest a special kind?
- Guest or regular worms
- Bugscope Team i'm not sure, i think they were sent to us by the school
- Bugscope Team scott or kate might know, but they are busy making presets at the moment
- Guest oh
- Bugscope Team if you wantch the session, the might have some insights for ya
- Guest when will the class be here?
- Guest oh I just figured out worm spine
- 3:36pm
- Guest alex?
- Guest anyone here
- Bugscope Team yes, sorry, we are busy setting up
- Bugscope Team what's up?
- Bugscope Team Hi Aditi! This is Scot, for a sec.
- Guest oh hi cate/scott
- Guest worm heads are not what I expected
- Guest what part of the worm is that hollow tube like thing
- Bugscope Team we think maybe it is the inside of a bristle
- 3:42pm
- Guest what is a bristle
- Bugscope Team i'm not sure, scott may know in a sec, he's on the phone
- Guest preset number 20 sounds mysterious
- Bugscope Team They are much like human hairs, with scales, apparently.
- Guest scales
- Bugscope Team I don't know if they are retractable; they do seem directional.
- Guest ithought fish only had scales
- Bugscope Team In this case we are thinking of the scaley nature of the surface, like a human hair.
- Guest when will the class be here
- Bugscope Team about 15 minutes, Aditi.
- Guest got it
- Bugscope Team Aditi if you Google up 'earthworm anatomy' you will be better able to help answer the kids' questions.
- 3:47pm
- Bugscope Team Unfortunately we only have the external anatomy here.
- Bugscope Team And we have a few insects
- Guest okay i'll do that
- Bugscope Team Um hi Hi!
- 3:52pm
- Bugscope Team knitting
- Bugscope Team Yeah that is wild.
- Guest knitting?
- Guest i see what you mean
- Bugscope Team the surface of the worm's 'skin' looks like fabric
- Guest the skin???????????????
- Guest thats the last thing i would think it was
- Bugscope Team this is where it is split open and we are peering into the subsurface
- Guest it split open?
- Guest The epidermis is the name for the skin of an earthworm. It is the outer layer of worm and it secretes a mucous.
- Bugscope Team yeah we critical point dried the worms so we could get them into the 'scope
- Bugscope Team so they are pretty dry
- Bugscope Team and it was cracked open
- Guest oh
- Bugscope Team we are probably looking at the skeleton of the mucus that you referred to
- Bugscope Team human skin is also called epidermis
- 3:57pm
- Bugscope Team mucus is a noun, anything refering to mucus is mucous, like mucous membranes
- Bugscope Team referring
- Guest what I wrote was about the only thing I understudd from my research
- Bugscope Team with what we have done to prepare the worm it can be difficult to tell if we are looking at the epidermis or the remnants of the slime
- Guest "mucous memmbranes" ?
- Bugscope Team mucous membranes are tissue at the surface of the skin that produce mucus
- Guest how many times have you done an earthworm for bugscope
- Guest got it
- Bugscope Team a membrane is thin like a sheet
- Bugscope Team Aditi this is the first time we have ever imaged earthworms using the electron microscope. Long ago we looked at vinegar eels or worms, whatever they are properly called.
- Guest vinegar eels????
- 4:03pm
- Bugscope Team yeah someone sent them about 9 years ago. they were hard to kill -- apparently they can live in nearly anything. they were super tiny -- you could hardly see them by eye.
- Guest whta are thay
- Bugscope Team I don't recall -- maybe they were nematodes
- Guest how could you handle them if they were super tiny
- Guest what aer we looking at now
- Bugscope Team um I thought it was a piece of grass, not sure
- Guest grass!!
- Bugscope Team we had to use droppers to manipulate the vinegar eels, and then super fine forceps.
- Guest I've never seen magnifyed grass!
- 4:09pm
- Guest whta do earthworms use their bristles for
- Bugscope Team The school should know what they are used for.
- Guest they should?
- Bugscope Team HI Karen!
- Guest hello karen
- Bugscope Team welcome to bugscope
- Teacher HELLO
- Bugscope Team i just unlocked the session, you should see control on the right side of the browser, Magnify, Navigation, Focus and Adjust
- Bugscope Team if you have any questions please feel free to ask
- Guest hi jojo
- Guest hi hi
- Student yo
- 4:14pm
- Student hi
- Guest hello shane
- Bugscope Team This is one of the bristles on the surface of the earthworm's body
- Teacher what is the magnification of this bristle
Bugscope Team the magnification is in the upper right
- Student hi
- Bugscope Team we think it looks kind of like a tooth, but also that with its scale-lilke features it resembles a human hair.
- Guest hi nate maltry
- Student this is awesome
- Student hi i'm nate
- Student hi
- Bugscope Team see the scalebar at the lower left?
- Student hi from sopie g
- Bugscope Team or if you click on the scale bar in the image (lower left) it'll bring up a key that has the magnification
- Guest I can't keep up! high everyone
- Student hi im cole
- Bugscope Team Ms Hall you have control of the microscope if you would like to drive, or change mag, etc.
- Student what is contras
- Student do you know what contrast means?
- Bugscope Team Alex, Aditi, and I are here to help answer questions when we can
- Student what is the base word for magnification
- Student what is a contrast
- Bugscope Team contrast is the difference between black and white
- Student gilly said she likes pie
- Student what is the stuff around the bristle?
- Student what`s around the bristle
Bugscope Team we are not sure -- it is the epidermis of the worm
- 4:19pm
- Student Hi
- Student Hi!
- Student who is driving the microscope
Bugscope Team karen is driving the scope, unless scott is?
- Student were is the mouth
- Guest hello alex
- Student hi scott
- Student can you show it
- Student ll likes seaweed
- Student who is driving the microscope
- Student cool
- Student hi scott and what is this?
- Student what is that
- Bugscope Team these are worms
- Bugscope Team note that there is a claw reaching out to the worm from the right
- Student karen
- Bugscope Team Karen is driving
- Student thanks
- Student do earth worms have hair?
- Bugscope Team this is just one worm
- Guest what is that claw for
- Student this is cool!
- Student What is the typical range of magnification used?
Bugscope Team for bugs it's 40x - 40,000x. but the scope can go much higher...
- Student what is this
- Student what is that part of the earthworm?
- Guest I think it is the head
- Student what is that
- Bugscope Team this is the back end -- the last few segments -- of the worm
- Student thats so freaky
- Bugscope Team pointing up toward us
- Student awesome
- Student hi is cool and my dad is a dumbo!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
- Student whats around the main picture
- Student what is the root word for magnification
- Bugscope Team Karen you may choose from among the presets on the right side of the chat box. If you click on one the microscope will drive to that place.
- Student wow
- Guest magnify
- Student wow!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
- Student What does contrast mean?
Bugscope Team contrast is the difference between dark and light
- Student what is the specimens that we sent?
- Student awesome!
- Student trast
- Student what does contrast mean?
- Bugscope Team something very black on a white background would be said to have high contrast.
- Student what r those dots?
- Student what does that weared thing scott
- Guest salt
- Student i cant see the questions
- Student what specimens did we send?
Bugscope Team you sent us worms
- Student what is the specimen we sent
- Bugscope Team something with lots of gray in it that makes it hard to see the samples would have low contrast
- 4:24pm
- Student what is the part of the worm you are showing
- Student what is the root word for magnification
Bugscope Team Latin: magnus = big
- Bugscope Team and also a moth, but I am afraid it got lost, so we put some other insects in the 'scope for today
- Guest another example of contrast is the difference between red and blue
- Guest one is a bright color the other is a dark color
- Student what does contrast mean
- Student what are the specimens placed on?
- Student HOW DO THEY DO THIS STUF
Bugscope Team electrons are shot at the worms, and they hit the worms causing a thin film of electrons to get knocked off, those knocked off electrons are collected by the secondary electron detector and that's how the image is made
- Student what is the specimen placed on?
Bugscope Team the samples are all on doublestick carbon tape
- Student can we see the mouth
Bugscope Team I just moved you to the mouth
- Student what is the specimen placed on?
- Student whet r the specimins placed on?
- Student what does multi user mean
Bugscope Team multiuser means, in our case, that many people use the lab here
- Student what is that
- Guest doublestick carbon tape
- Bugscope Team but you can drive the microscope yourselves
- Student THAT LOOKS LIKE A BEAK
- Student thanks
- Student thakyou for all your doing!
- Guest multi user means more than one user
- Student this is kind of wierd
Bugscope Team there is lots of fungus on the surface of the worm, and also, the remnants of the slime, or mucus
- Bugscope Team as Aditi says
- Student SWEAT
Bugscope Team super sweet
- Student what is that?
- Student can we see the kllitelim
- Student where are speciments placed
- Student What does contrast mean?
Bugscope Team contrast means dark versus light
Bugscope Team contract is the different between light and dark
- Student can i see the mouth closer
- Student can i see the mouth closer
- Student this is incredible!
- Student go back go back
Bugscope Team your teacher has control!
- Student are those hairs?
- Student can we see the clytelum
- Student CAN WE SEE THE END
- Student were is the clitelum
- 4:29pm
- Student mine isnt working
Bugscope Team if your image is black, try hitting refresh (F5)
- Student wow thats cool
- Student What does multi-user mean?
Bugscope Team a unicycle is single-user. a car is multi-user....
- Student what is that
- Student cool
- Guest more than one persoon is what multi user means
- Student what are spedimens placed on
- Bugscope Team this is the mouth of the worm
- Student what is that
- Student COOL
- Bugscope Team this is pretty awesome
- Student that is so cool
- Student A WORM
- Student what is that?
- Bugscope Team this is the surface of the epidermis of the worm
- Student where is the worm
- Bugscope Team it looks so much like fabric, but it is not woven
- Student THER
- Guest you are looking at the worm right now
- Student zoom out all the way
- Bugscope Team now we see a crack
- Student PLEAS
- Bugscope Team oops not now
- Student thanks for doing this!
Bugscope Team this is fun for us Sophia.
- Guest yes it is
- Student what do specimen get placed on
Bugscope Team on carbon tape, on an aluminum stub
- Student tanks thanks
- Student HI I AM MAX MM
- Guest hello MAX MM
- Bugscope Team this is one of the cracks between the segments
- Student is it alive?
Bugscope Team nope, they are dead. they need to be very still inside the scope so we can get good images
- Guest how many segments do worms have
- Student A CRAK!!!!!!!
- 4:34pm
- Student thanks
- Bugscope Team yep, things dry out without moisture, and when things die they can dry out, and thus you'll see crack and stuff like that
- Guest my class sent in an antlion and it was alive so we never got to see it
- Bugscope Team now we see some fungus
- Student THATS ALOT OF HAIR
- Guest I did but not the rest of my class
- Student what is that
- Bugscope Team we think this is the inside of one of the bristles
- Student A HOLL
- Student wow
- Bugscope Team now, this is pretty cool
- Student what is that
- Guest yep its a hole
- Student SPIN?
- Student cool
- Student A HEAD
- Student coooooooooooooooooooooooooooooooooooool

- Student AWSOME!!!!
- Student WOW
- Student oh my
- Guest a worms body is made up of segments
- Student WHAT IA A TOOTH FOOT
- Student what is a tooth foot
Bugscope Team it's really one of the bristles
- Student what is a tooth foot
- Bugscope Team not really a tooth or a foot
- Bugscope Team but we called it an odontopod as a joke
- Student REALY
- Guest what grade are you guuys in?
- Student 4TH
- Student what does multi user mean?
Bugscope Team multiuser means that many people can use the facility, or whatever it is that you are referring to
- Student what all of that hairy stuff
- Bugscope Team this is a place where the epidermis was torn open
- Student CRIKET
- Guest multi user means more than one user
- Student what does multi user mean?
- Student WOW
- Guest got to go bye
- Bugscope Team this is part of a cricket, next to our worm friends
- Student what is that
- Student where is its botom
Bugscope Team further south, Hiram
- 4:39pm
- Student LEG
- Guest see you afew months later scott
Bugscope Team whoa that is a long time

- Student what is that
- Bugscope Team See you Aditi!
- Student CLAW
- Student wow
- Student
- Bugscope Team this is a claw for sure
- Student cool
- Bugscope Team yep, this is a claw
- Student A LADY BUG
- Bugscope Team a claw on a ladybug
- Student REALY
- Bugscope Team yup a ladybug
- Student cool
- Student can we see its mouth
- Student HAIRE AGAIN
- Student cool
- Bugscope Team and these are special setae, they help the ladybug to stick to walls when it's climbing. these are called tenent setae
- Student
- Bugscope Team this is how bugs breath! this is a spiracle
- Student do you like youre job?
Bugscope Team yes this is a fun job
- Bugscope Team bugs don't breath through their mouths, they have holes in their bodies and breath through them
- Bugscope Team this is how they breathe
- Student WHAT THE
- Student
- Bugscope Team breathe, i'm sorry...
- Student where is this on the body?
Bugscope Team often the spiracles are on the sides of the body
- Student
- Student WA
- Student
- Bugscope Team insects have segmented bodies too
- Student I wish i had this job
- Bugscope Team this is one of the halteres
- Student do all bugs have setae?
Bugscope Team I think so, can't think of one that does not
- Bugscope Team and the pore-like thing is another spiracle
- Student
- Student WHAT THE HEAK IS A TRUE BUG
Bugscope Team True Bugs are classified as Hemiptera, and they have specific features like piercing mouthparts that make them part of that group.
- Student fruit flys rock
- Bugscope Team this is an eye!
- Student what is that
- Bugscope Team some insects have compound eyes, that are made up of hundreds of those bumps, called ommatidia
- 4:45pm
- Student this is fun
Bugscope Team yeah it is fun for us as well
- Bugscope Team the spikes are setae, and they are thought to help flying insects fly better
- Student THANK YOU SCOT
Bugscope Team No problem Max
- Bugscope Team each of those bumps has an eye lens in it
- Student coooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooool
- Student EYE
- Student wh
- Bugscope Team this is another compound eye, but the ommatidia are dried out, and thus they kind shrunk a bit
- Bugscope Team this is the eye of a mosquito, and it is fairly dry
- Bugscope Team there now you can see the head
- Student HEAD
- Bugscope Team on the lower left
- Student wow do you like this?
- Student TOUNG
- Bugscope Team the proboscis is sticking out toward us
- Student thats cool and groos at the same time
Bugscope Team yeah that is out specialty ; )
- Bugscope Team totally
- Student IT LOOKS LIKE A CLAW
- Student proboscis
- Bugscope Team this must be a smile with food dripping out of the mouth )'
- Student funny
- Student this is pretty cool
- Student
- Bugscope Team only female mosquitos bite
- Bugscope Team all those hairs are setae and they reallyhelp the little buggers to sense their environment
- Student MAN
- Student grass hopper
- Bugscope Team and the biting parts are inside of the proboscis
- Student i want to make a song this is so cool do you?
Bugscope Team yes a song would be good about now, but it would look like a poem
- Student Could we get closer please?
Bugscope Team Karen can make the 'scope get closer.
- Bugscope Team without those setae, they'd be unable to feel much of anything. that's because their outside is a hard exoskeleton, like wearing a suit of armour
- Student ONLY THE FEMAIL BITES
Bugscope Team that is right. the female needs a blood meal so she can successfully lay her eggs.
- Bugscope Team a song! that would be way cool man
- 4:50pm
- Bugscope Team karen, we can give control to a student, if you want us to?
- Student what is that?
- Teacher that's Ok
- Bugscope Team this is one of the bristles on the worm's body
- Student what is that
- Student song time
- Teacher no thanks
- Student THAT WASENT A QUESTION
- Student good thing both dont bite
- Bugscope Team whatever you think is best karen
- Student that looks like a whale
- Bugscope Team No thanks to the song? We were looking forward to it!
- Bugscope Team It does -- it looks like a sperm whale tooth.
- Student what time did u start magnfying the worm
Bugscope Team just before you got on today
- Student what time did you start magnifing bugs
Bugscope Team we started setting up for this session at 3PM central, 2 hours ago
- Bugscope Team It is so cool that is has a scaley surface, much like a human hair
- Student YAU
- Student I FORGOT ,DOES THE EARTHWORM HAVE ANY BONES?
Bugscope Team no they are invertebrates -- so they have no backbone, and no bones at all.
Bugscope Team nope, no bones, no spin, it is an invertebrate
- Student
- Student
- Student YA
- Bugscope Team see the piercing proboscis?
- Bugscope Team and the eyes?
- Student yes
- Student aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa! thats scary
- Bugscope Team and the two antennae?
- Bugscope Team spine, i mean
- Student YA
- Student what is your favorate picture Hiram
- Bugscope Team this insect pierces whatever it eats and sucks the juice out
- Student cooool
- Student whoooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
- 4:55pm
- Student misqueto head
- Student what is youre favorite?
- Student EXOSKELITON
Bugscope Team insects have exoskeletons -- that is correct. they are also invertebrates, like earthworms
- Bugscope Team Hiram this is a true bug -- what stinkbugs are, and assassin bugs, and ambush bugs
- Student Cooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooool
- Student SO WHAT IS THIS ?
- Student Is that the head?
Bugscope Team yeah to the right
- Student how did you get this job its cool
Bugscope Team we started Bugscope 10 years ago. I started doing electron microscopy in college
- Student WHAR AR THE ANTANA ON THIS THING
Bugscope Team to the right
- Student I want to have that job!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
- Bugscope Team you all could totally have a job like this, if you take time to work at something, you can do just about anything
Bugscope Team Alex is right.
- Student cool
- Student what is this
- Student thank you for showing us the worms and the other bugs
Bugscope Team Thank You LeeC
- Student I think so.
- Bugscope Team one antenna is broken or pointed away so we cannot see it fully
- Student thank you
