- 12:59pm
- Bugscope Team session enabled, rxl started, starting presets
- 1:05pm
- Bugscope Team ambush bug!
- 1:11pm
- Bugscope Team this is interesting: The most distinctive feature of the family is that the tip of the proboscis fits into a groove in the prosternum, where it is rasped against ridges there (a stridulitrum) to produce sound.
- Bugscope Team hello sciencetacher1, welcome to bugscope
- Bugscope Team we are setting up for today's session at 2PM
- 1:16pm
- Bugscope Team mites*
- Bugscope Team yay!
- Bugscope Team aww a whole family
- 1:22pm
- 1:30pm
- Bugscope Team presets done, session unlocked, we are ready!
- Teacher Hi Everyone!
- 1:35pm
- Bugscope Team hi Mrs. Burk, welcome to Bugscope!
- Bugscope Team Welcome to Bugscope!
- Bugscope Team Let us know if you have any questions. You can drive around now to get a feel for it if you want
- Bugscope Team Yeah we are ready to roll.
- Bugscope Team Welcome!
- Bugscope Team an assortment of scales
- Bugscope Team this is a very small moth
- 1:40pm
- Bugscope Team it looks Elizabethan, with a lace collar
- Teacher Hi Scott and everyone else! Thanks for being there today. The kids will be in soon, will you give directions to run the microscope or will that be my job?
- Bugscope Team are you going to let the kids drive?
- Bugscope Team they will be able to, one at a time, if you wish
- Teacher Yes, if that's ok. I have my older kids today grades 3-5.
- Bugscope Team we can confer control to anyone you want or leave it all to you
- Bugscope Team so please just let us know who you would like to have control
- Teacher Please help out! This is only my second time and I am not proficient like you!
- Bugscope Team you bet!
- Teacher OK Im going to get them settled in. It'll be a few minutes, then well get started with about 12 students
- Bugscope Team actually Mrs B I will have to peel out of here but Cate, Alex, Chas, and I think at least Jon will be on to help.
- Teacher Great! Thanks!
- 1:49pm
- Bugscope Team hello, i'm back. welcome mrs. burk, glad to have you at bugscope
- Bugscope Team let us know if you have any questions or any problems driving
- Bugscope Team this is me, moving to the tympanum...
- Bugscope Team "The tympanum, the auditory structure that lets crickets hear, is located on the first pair of legs near the "elbow" or "knee" joint."
- Teacher Hi We're ready to go!
- Bugscope Team okay, the scope is all yours
- Bugscope Team please ask any questions you may have
- Bugscope Team That was from the Ohio State University web site on crickets.
- Bugscope Team if you would prefer to have us control the scope, so you can ask more questions, we can do that too. it's totally up to you
- 1:54pm
- Teacher Justine-What is that?
- Bugscope Team This is a spine on the arm of the cricket
- Bugscope Team the background is silver paint on carbon tape
- Bugscope Team now we have moved in toward the body
- Teacher Courtney-Do crickets have hair?
Bugscope Team lots! a lot of insects have more hair than they seem at first
- Bugscope Team they have lots of tiny hairs called 'setae'
- Bugscope Team well, yes, they do, but those hairs are called setae (see-tee)
- Bugscope Team this is a view that allows us to see how crickets hear using their front legs
- Bugscope Team those hairs, setae, are connected to nerves underneath the exoskeleton, and so that's how bugs sense their environment, via those setae. it's kind of like cat whiskers.
- Teacher Amber-Can we see the whole cricket?
- Bugscope Team the indentation on the tibia -- the smoother area on this limb -- is the tympanum
- Bugscope Team which is like an ear drum
- Bugscope Team this is as low as we can go with magnification
- Bugscope Team well, we are at minimum resolution now, so this is as far out as we can get
- Bugscope Team you can see the whole head though
- Bugscope Team it is a small cricket too. with a bigger one we wouldnt be able to see this much
- Bugscope Team and check out it's eyes, insects have really cool eyes
- Teacher Thanks! So crickets hear with their legs?
- Bugscope Team this is a female cricket
- Bugscope Team the tympanum is built to pick up sound much like a human ear drum
- Bugscope Team the indentation on the leg is the cricket's ears
- Bugscope Team you can kind of see it from here in the middle of the image
- 1:59pm
- Bugscope Team one of the presets also shows the sawtooth stucture the cricket has that allows it to stridulate, which is what the noise is called.
- Teacher sorry we were trying to get in closer to the ear
- Bugscope Team you can see the indentation on the left of the cricket too
- Bugscope Team both tympani were visible for a sec
- Bugscope Team now you can see both
- Bugscope Team Mrs B I have to hike out of here. Would you like one of us to drive? (Not me...)
- Bugscope Team there see it?
- Teacher yes
- Bugscope Team nice, mrs. burk, you got it
- Teacher do crickets hae entenas?
- 2:05pm
- Bugscope Team yep, they sure do, on top of their heads
- Bugscope Team they usually are b
- Bugscope Team are broken off
- Bugscope Team they do not travel well
- Bugscope Team mrs. burk, if you get lost, try clicking on a preset, that will take you directly to that location
- Bugscope Team we've made the presets be interesting locations on the sample (cate made the sample), as best we could
- Bugscope Team ah, cool, this is part of a wasp antenna, broken, and you can see the inside of the antenna. looks pretty interesting, huh?
- Bugscope Team this is kind of interesting because the antenna broke at some point when i put the insect on the stub
- Bugscope Team you can see inside the antenna
- Teacher yes
- Bugscope Team notice the scale bar in the lower left of the image, that tells you the size of what you are looking at. 1 um = one millionth of a meter.
- 2:10pm
- Teacher Justine" What are the cylinders inside?
- Bugscope Team i'm not sure justine, what those cylinders are. maybe cate knows? we so rarely see inside an antenna like this.
- Teacher Mike is going to drive
- Bugscope Team well the antennae is a way for the insect to smell. maybe the olfactory receptors can travel through there
- Bugscope Team But dont quote me on that please, it was just a guess
- Teacher can we look at the teeth
- Bugscope Team most insects have a pair of jaws that are hinged
- 2:15pm
- Bugscope Team you can kind of see one side though it is hard to see, it just looks like a beak
- Bugscope Team this is on a wasp by the way
- Bugscope Team palps are sticking out of the mouth, they look like little antennae
- Bugscope Team palps help the insect taste or move food
- Teacher where is its stinger
- Teacher Amber is driving and asking questions now
- Bugscope Team you can try driving to the south
- Bugscope Team im not sure if you can see the stinger on this one, but we can try
- Bugscope Team and try lowering the mag one click
- Bugscope Team there you go goo driven
- Bugscope Team good
- Bugscope Team usually a stinger will be sticking straight down, im not sure what is sticking out to the side
- Bugscope Team kind of odd
- Teacher josh says it looks like it can dig into you
- 2:21pm
- Teacher David is driving. Can we see a butterfly?
- Bugscope Team sure go ahead
- Bugscope Team ah, sorry david, we don't have a butterfly on the scope today
- Bugscope Team we dont have a butterfly, but we have a moth
- Bugscope Team butterfly's are often very big, and so when we put them in the scope, it's usually only the wing
- Bugscope Team here is its head
- Bugscope Team its antennae are broken too
- Bugscope Team or preset 18
- Bugscope Team you can it has HUGE eyes
- Bugscope Team notice the eye has many bumps on it? those bumps are called ommatidia, they are individual facets of the compoud eye
- Bugscope Team compound eye, that is
- Teacher Justine says it looks like honeycombs
Bugscope Team yes they do
- Bugscope Team yes, the compound eye looks like a honeycomb because it's a hexagon shape. notice the surface of the compound eye is curved, and those hexagons make it easier for the surface to be curved. imagine if they were squares? it'd be a lot harder for the surface to curve like it does
- Teacher Nick-maybe they can only see by heat? Is that why they go by lights
Bugscope Team no, i don't believe the vision of the moth is based on thermal sense. it actually sees an image the same way our human eyes do. however, our eye is much more complex than the moths single eye facet (ommatidia). but they have hundreds of them!
- Bugscope Team heh the eyes would look like a cube if they were squares i imagine
- 2:28pm
- Bugscope Team this microscope can magnify up to 600,000x or more, but for images of bugs, it's best to stay at 40x - 40,000x or so
- Bugscope Team nick, if you want to find another bug, try clicking on a preset
- Bugscope Team Over the millennia, moths navigated at night by the light of the moon. To fly in a given direction, they would keep the moon in a fixed location. When you have artificial light, it throws off their internal GPS
- Bugscope Team or here ya, go this is another moth
- Teacher wings?
- Bugscope Team there are scales, yes, on the wing, i think
- Bugscope Team try zooming out a click or two, that will tell us for sure
- Bugscope Team yes scales are on the wings
- Teacher is that his tongue?
Bugscope Team yes its proboscis is curcled up in between its eyes
- Bugscope Team this moth has its wings folded around its body a little. butterfly wings are usually spread out
- Bugscope Team can any of you guess what the largest proboscis is in the world?
- 2:34pm
- Bugscope Team we've driven off the edge, need to fix the scope now
- Student we had a mouse error..sorry if we messed you up.
- Bugscope Team lol
- Bugscope Team it happens dont worry
- Bugscope Team not a problem deb, we are good now. mrs. burk has control again
- Bugscope Team this is a spined bark borer
- Bugscope Team the largest proboscis in the world is the elephant proboscis
- Bugscope Team it is a longhorn beetle
- Bugscope Team but good guess on the hummingbird!
- Student What is a bark borer
- Bugscope Team it doesnt really have horns, but it has super long antennae that are as long as or longer than its body
- Bugscope Team it can drill perfectly round holes into trees
- Bugscope Team a bark borer is a type of longhorn beetle
- Bugscope Team you might have heard of the asian longhorn beetle that kills maple and elm trees
- Student nicole is going to drave and ask ?s
- 2:39pm
- Student no tell us more
- Bugscope Team yay, nicole!
- Bugscope Team the larvae of this beetle have a voracious appetite for wood. It is especially damaging to maple trees
- Bugscope Team Females of this species chew into the bark and lay eggs. When the eggs hatch, the immature beetles, which look like big white worms, chew their way farther into the tree. When they mature, the full-grown beetles chew their way out of the tree.
- Student how do I drive
- Bugscope Team i imagine the bark borer does something similar by the sound of its name
- Bugscope Team you have controls now if you want to try
- Student what part is that?
- Bugscope Team normally, the teacher has control. we have to give control to any other students logged in. so just ask us if you want control
- Bugscope Team looks like its near the mouth. kind of like a chin
- Student Actually, Deb and Mrs burk are the same person. Mrs. Burk didn't realize how to log students in and when we went off the screen I logged in as Deb. Newbie at work!
- Bugscope Team that is no problem at all
- Bugscope Team hey no problem mrs. burk.
- 2:44pm
- Student Justine's Driving-
- Bugscope Team hi justine! fasten your seat belt everyone...
- Bugscope Team heh
- Student can we see a mosquito?
- Bugscope Team this scope is an ESEM (environmental scanning electron microscope), it is about 10 years old, and cost $750,00 when we got it
- Bugscope Team ah, sorry, it doesn't look like we have a mosquito today
- Student tick?
- Bugscope Team we have a fruit fly, moth, beetle, ambush bug, wasp and some salt from wendy's
- Bugscope Team we have mites
- Bugscope Team it is similar to a tick
- Bugscope Team well, not a tick, but there is a colony of mites on an earwig, preset #12
- Bugscope Team but instead of ticks on a mammal, we have mites on an insect!
- Student mites!
- Bugscope Team try preset #12, it's a colony of mites
- Bugscope Team just click on the preset image (lower right) and the scope will move there automatically
- Bugscope Team ah, yeah, coo, check them out, they are a happy little mite family
- Bugscope Team these are mites
- Bugscope Team kind of like turtles
- 2:49pm
- Bugscope Team the mites are hitching a ride on an earwig
- Bugscope Team there are 5 that i can see here
- Student it looks like they are sideways
- Student 5?
- Bugscope Team yeah, they cling onto whatever surface they can attach to
- Student george is driving
- Bugscope Team yes, i see 3 for sure, and maybe two more, unless those other two are some other bumps of some kind
- Bugscope Team they are sideways, we are kind of just seeing their profile
- Bugscope Team hi george!
- Bugscope Team this is a palp on a wasp
- Student what is a pelp
Bugscope Team they allow the insect to taste food and move the food around
- Student what is that big glab
- Bugscope Team yeah, a palp is an appendage that comes off the head/mouth area
- Bugscope Team well, that big glab looks like dirt or dust. bugs can get quite dirty!
- 2:54pm
- Student mike is driving
- Bugscope Team we call dirt or dust juju. it's a little nickname we have for it ;)
- Bugscope Team hi mike! drive away!
- Student addie is driving
- Bugscope Team this is salt from wendy's restaurant
- Bugscope Team it looks cool because of the shapes
- Bugscope Team in the cubs
- Bugscope Team cubes
- Bugscope Team yeah, wendy's salt is odd because they must add something to it that makes the salt cubes look different. normal salt doesn't look like this
- Bugscope Team try magnify to see it closer
- Student why is solt on the bugscope
Bugscope Team well, we just think it's a neat thing to look at some odd looking salt. it really has nothing to do with insects.
- 2:59pm
- Bugscope Team heh we like to put different things in the scope. we get a little bored always seeing bugs
- Bugscope Team although, salt is critical to all life on this planet, so in that way salt is related to bugscope.... ???
- Student Our time is up! We all want to thank you Bugscope people for your "time and effort".
- Bugscope Team awww
- Student Sure Alex! That works!
- Bugscope Team well thanks for your questions, I hope you all had fun!
- Bugscope Team and of course we hope you come back next year
- Bugscope Team thank you! we hope you enjoyed your session and learned something
- Student We did! We will!
- Bugscope Team mrs. burk, all the chat and images from the session are saved to your bugscope member page: http://bugscope.beckman.uiuc.edu/members/2008-046
- Student Thank you Alex...I'll be in touch with my followup!
- Bugscope Team you are welcome to access that page anytime, we keep all members pages online indefinitely. you can access the page with your bugscope password, same as for this session
- 3:05pm
- Bugscope Team okay, nice session everyone. i will start to close down the scope, unless anyone has any more questions?
- Student Phew, they're gone... I thought they would be more wound up about this, but maybe I should have done different prepping.
- Bugscope Team you did great
- Bugscope Team you did great as jon says
- Student Maybe another time I should send some insects we have more access to. When I mentioned the tick they really wanted to know more. We are having a terrible time with them! We even had a live one in here during the session!
- Bugscope Team oh cool
- Bugscope Team deb, sometimes we prefer to have students login, so they can ask questions themselves. we find in that way they seem to be more engaged. however, that has it's problems too, as it can get very busy, lots of chat lines, and make it harder to read
- Student They were the ones asking questions! Did you think that spelling was me????
- 3:10pm
- Student I need to figure out how to log them in
- Bugscope Team true, and like cate says, not everyone has access to so many computers.
- Bugscope Team ah, no deb, i'm a terrible speller myself, so i don't judge others on it ;)
- Student We were using one computer. Would it have made sense if everyone had a computer?
- Bugscope Team when you login as teacher, then any other person who logs in will only have the option to login as a student
- Student We used a projector up on the wall
- Bugscope Team ah yes, if you have only one computer, then it's best to have just one login
- Bugscope Team and a projector, yes, lots of teachers use a projector as well
- Student OK so next time I will have every kid on a computer and you will have bugs from Dresden. Thanks Guys!
- Bugscope Team thank you deb, see you later!
- Student Bu Bye!
- Bugscope Team ciao
- Bugscope Team session disabled, rxl stopped, session locked, users logged off.
- Bugscope Team session is done, nice one everyone, see you later!
- Bugscope Team bu bye
- Bugscope Team heh
