• 12:59 pm
• Bugscope Teamsession enabled, rxl started, starting presets

• 1:05 pm

• Bugscope Teamambush bug!

• 1:11 pm
• Bugscope Teamthis 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 Teamhello sciencetacher1, welcome to bugscope

• Bugscope Teamwe are setting up for today's session at 2PM
• 1:16 pm

• Bugscope Teammites*
• Bugscope Teamyay!
• Bugscope Teamaww a whole family

• 1:22 pm

• 1:30 pm

• Bugscope Teampresets done, session unlocked, we are ready!
• TeacherHi Everyone!
• 1:35 pm
• Bugscope Teamhi Mrs. Burk, welcome to Bugscope!
• Bugscope TeamWelcome to Bugscope!
• Bugscope TeamLet us know if you have any questions. You can drive around now to get a feel for it if you want
• Bugscope TeamYeah we are ready to roll.
• Bugscope TeamWelcome!

• Bugscope Teaman assortment of scales

• Bugscope Teamthis is a very small moth
• 1:40 pm

• Bugscope Teamit looks Elizabethan, with a lace collar
• TeacherHi 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 Teamare you going to let the kids drive?
• Bugscope Teamthey will be able to, one at a time, if you wish
• TeacherYes, if that's ok. I have my older kids today grades 3-5.
• Bugscope Teamwe can confer control to anyone you want or leave it all to you
• Bugscope Teamso please just let us know who you would like to have control
• TeacherPlease help out! This is only my second time and I am not proficient like you!
• Bugscope Teamyou bet!
• TeacherOK Im going to get them settled in. It'll be a few minutes, then well get started with about 12 students
• Bugscope Teamactually 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.
• TeacherGreat! Thanks!

• 1:49 pm
• Bugscope Teamhello, i'm back. welcome mrs. burk, glad to have you at bugscope
• Bugscope Teamlet us know if you have any questions or any problems driving
• Bugscope Teamthis 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."
• TeacherHi We're ready to go!
• Bugscope Teamokay, the scope is all yours
• Bugscope Teamplease ask any questions you may have
• Bugscope TeamThat was from the Ohio State University web site on crickets.

• Bugscope Teamif 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
• 1:54 pm
• TeacherJustine-What is that?

• Bugscope TeamThis is a spine on the arm of the cricket
• Bugscope Teamthe background is silver paint on carbon tape
• Bugscope Teamnow we have moved in toward the body
• TeacherCourtney-Do crickets have hair?
  Bugscope Teamlots! a lot of insects have more hair than they seem at first
• Bugscope Teamthey have lots of tiny hairs called 'setae'
• Bugscope Teamwell, yes, they do, but those hairs are called setae (see-tee)

• Bugscope Teamthis is a view that allows us to see how crickets hear using their front legs
• Bugscope Teamthose 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.
• TeacherAmber-Can we see the whole cricket?

• Bugscope Teamthe indentation on the tibia -- the smoother area on this limb -- is the tympanum
• Bugscope Teamwhich is like an ear drum
• Bugscope Teamthis is as low as we can go with magnification
• Bugscope Teamwell, we are at minimum resolution now, so this is as far out as we can get
• Bugscope Teamyou can see the whole head though
• Bugscope Teamit is a small cricket too. with a bigger one we wouldnt be able to see this much
• Bugscope Teamand check out it's eyes, insects have really cool eyes
• TeacherThanks! So crickets hear with their legs?
• Bugscope Teamthis is a female cricket
• Bugscope Teamthe tympanum is built to pick up sound much like a human ear drum
• Bugscope Teamthe indentation on the leg is the cricket's ears
• Bugscope Teamyou can kind of see it from here in the middle of the image
• 1:59 pm
• Bugscope Teamone of the presets also shows the sawtooth stucture the cricket has that allows it to stridulate, which is what the noise is called.

• Teachersorry we were trying to get in closer to the ear

• Bugscope Teamyou can see the indentation on the left of the cricket too
• Bugscope Teamboth tympani were visible for a sec

• Bugscope Teamnow you can see both

• Bugscope TeamMrs B I have to hike out of here. Would you like one of us to drive? (Not me...)
• Bugscope Teamthere see it?
• Teacheryes
• Bugscope Teamnice, mrs. burk, you got it
• Teacherdo crickets hae entenas?
• 2:05 pm
• Bugscope Teamyep, they sure do, on top of their heads
• Bugscope Teamthey usually are b
• Bugscope Teamare broken off
• Bugscope Teamthey do not travel well

• Bugscope Teammrs. burk, if you get lost, try clicking on a preset, that will take you directly to that location
• Bugscope Teamwe've made the presets be interesting locations on the sample (cate made the sample), as best we could

• Bugscope Teamah, cool, this is part of a wasp antenna, broken, and you can see the inside of the antenna. looks pretty interesting, huh?
• Bugscope Teamthis is kind of interesting because the antenna broke at some point when i put the insect on the stub
• Bugscope Teamyou can see inside the antenna
• Teacheryes
• Bugscope Teamnotice 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.
• 2:10 pm
• TeacherJustine" What are the cylinders inside?
• Bugscope Teami'm not sure justine, what those cylinders are. maybe cate knows? we so rarely see inside an antenna like this.
• TeacherMike is going to drive

• Bugscope Teamwell the antennae is a way for the insect to smell. maybe the olfactory receptors can travel through there
• Bugscope TeamBut dont quote me on that please, it was just a guess
• Teachercan we look at the teeth

• Bugscope Teammost insects have a pair of jaws that are hinged
• 2:15 pm
• Bugscope Teamyou 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 Teampalps are sticking out of the mouth, they look like little antennae
• Bugscope Teampalps help the insect taste or move food
• Teacherwhere is its stinger
• TeacherAmber is driving and asking questions now
• Bugscope Teamyou can try driving to the south
• Bugscope Teamim not sure if you can see the stinger on this one, but we can try

• Bugscope Teamand try lowering the mag one click

• Bugscope Teamthere you go goo driven
• Bugscope Teamgood
• Bugscope Teamusually a stinger will be sticking straight down, im not sure what is sticking out to the side

• Bugscope Teamkind of odd
• Teacherjosh says it looks like it can dig into you
• 2:21 pm
• TeacherDavid is driving. Can we see a butterfly?
• Bugscope Teamsure go ahead
• Bugscope Teamah, sorry david, we don't have a butterfly on the scope today
• Bugscope Teamwe dont have a butterfly, but we have a moth

• Bugscope Teambutterfly's are often very big, and so when we put them in the scope, it's usually only the wing
• Bugscope Teamhere is its head

• Bugscope Teamits antennae are broken too
• Bugscope Teamor preset 18
• Bugscope Teamyou can it has HUGE eyes

• Bugscope Teamnotice the eye has many bumps on it? those bumps are called ommatidia, they are individual facets of the compoud eye
• Bugscope Teamcompound eye, that is
• TeacherJustine says it looks like honeycombs
  Bugscope Teamyes they do
• Bugscope Teamyes, 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
• TeacherNick-maybe they can only see by heat? Is that why they go by lights
  Bugscope Teamno, 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 Teamheh the eyes would look like a cube if they were squares i imagine
• 2:28 pm

• Bugscope Teamthis 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 Teamnick, if you want to find another bug, try clicking on a preset
• Bugscope TeamOver 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 Teamor here ya, go this is another moth
• Teacherwings?
• Bugscope Teamthere are scales, yes, on the wing, i think
• Bugscope Teamtry zooming out a click or two, that will tell us for sure

• Bugscope Teamyes scales are on the wings
• Teacheris that his tongue?
  Bugscope Teamyes its proboscis is curcled up in between its eyes

• Bugscope Teamthis moth has its wings folded around its body a little. butterfly wings are usually spread out

• Bugscope Teamcan any of you guess what the largest proboscis is in the world?
• 2:34 pm
• Bugscope Teamwe've driven off the edge, need to fix the scope now
• Studentwe had a mouse error..sorry if we messed you up.
• Bugscope Teamlol
• Bugscope Teamit happens dont worry

• Bugscope Teamnot a problem deb, we are good now. mrs. burk has control again
• Bugscope Teamthis is a spined bark borer
• Bugscope Teamthe largest proboscis in the world is the elephant proboscis
• Bugscope Teamit is a longhorn beetle
• Bugscope Teambut good guess on the hummingbird!
• StudentWhat is a bark borer
• Bugscope Teamit doesnt really have horns, but it has super long antennae that are as long as or longer than its body
• Bugscope Teamit can drill perfectly round holes into trees
• Bugscope Teama bark borer is a type of longhorn beetle
• Bugscope Teamyou might have heard of the asian longhorn beetle that kills maple and elm trees
• Studentnicole is going to drave and ask ?s
• 2:39 pm
• Studentno tell us more
• Bugscope Teamyay, 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.
• Studenthow do I drive
• Bugscope Teami imagine the bark borer does something similar by the sound of its name
• Bugscope Teamyou have controls now if you want to try

• Studentwhat part is that?

• Bugscope Teamnormally, the teacher has control. we have to give control to any other students logged in. so just ask us if you want control
• Bugscope Teamlooks like its near the mouth. kind of like a chin
• StudentActually, 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 Teamthat is no problem at all
• Bugscope Teamhey no problem mrs. burk.
• 2:44 pm
• StudentJustine's Driving-
• Bugscope Teamhi justine! fasten your seat belt everyone...
• Bugscope Teamheh
• Studentcan we see a mosquito?
• Bugscope Teamthis scope is an ESEM (environmental scanning electron microscope), it is about 10 years old, and cost $750,00 when we got it
• Bugscope Teamah, sorry, it doesn't look like we have a mosquito today
• Studenttick?
• Bugscope Teamwe have a fruit fly, moth, beetle, ambush bug, wasp and some salt from wendy's
• Bugscope Teamwe have mites
• Bugscope Teamit is similar to a tick
• Bugscope Teamwell, not a tick, but there is a colony of mites on an earwig, preset #12
• Bugscope Teambut instead of ticks on a mammal, we have mites on an insect!
• Studentmites!
• Bugscope Teamtry preset #12, it's a colony of mites
• Bugscope Teamjust click on the preset image (lower right) and the scope will move there automatically

• Bugscope Teamah, yeah, coo, check them out, they are a happy little mite family
• Bugscope Teamthese are mites

• Bugscope Teamkind of like turtles
• 2:49 pm

• Bugscope Teamthe mites are hitching a ride on an earwig
• Bugscope Teamthere are 5 that i can see here
• Studentit looks like they are sideways

• Student5?
• Bugscope Teamyeah, they cling onto whatever surface they can attach to
• Studentgeorge is driving
• Bugscope Teamyes, i see 3 for sure, and maybe two more, unless those other two are some other bumps of some kind
• Bugscope Teamthey are sideways, we are kind of just seeing their profile
• Bugscope Teamhi george!

• Bugscope Teamthis is a palp on a wasp

• Studentwhat is a pelp
  Bugscope Teamthey allow the insect to taste food and move the food around

• Studentwhat is that big glab
• Bugscope Teamyeah, a palp is an appendage that comes off the head/mouth area
• Bugscope Teamwell, that big glab looks like dirt or dust. bugs can get quite dirty!
• 2:54 pm
• Studentmike is driving
• Bugscope Teamwe call dirt or dust juju. it's a little nickname we have for it ;)
• Bugscope Teamhi mike! drive away!

• Studentaddie is driving

• Bugscope Teamthis is salt from wendy's restaurant
• Bugscope Teamit looks cool because of the shapes
• Bugscope Teamin the cubs
• Bugscope Teamcubes
• Bugscope Teamyeah, 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 Teamtry magnify to see it closer

• Studentwhy is solt on the bugscope
  Bugscope Teamwell, we just think it's a neat thing to look at some odd looking salt. it really has nothing to do with insects.

• 2:59 pm

• Bugscope Teamheh we like to put different things in the scope. we get a little bored always seeing bugs

• Bugscope Teamalthough, salt is critical to all life on this planet, so in that way salt is related to bugscope.... ???
• StudentOur time is up! We all want to thank you Bugscope people for your "time and effort".
• Bugscope Teamawww
• StudentSure Alex! That works!
• Bugscope Teamwell thanks for your questions, I hope you all had fun!
• Bugscope Teamand of course we hope you come back next year
• Bugscope Teamthank you! we hope you enjoyed your session and learned something
• StudentWe did! We will!
• Bugscope Teammrs. burk, all the chat and images from the session are saved to your bugscope member page: http://bugscope.beckman.uiuc.edu/members/2008-046
• StudentThank you Alex...I'll be in touch with my followup!
• Bugscope Teamyou 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
• 3:05 pm
• Bugscope Teamokay, nice session everyone. i will start to close down the scope, unless anyone has any more questions?
• StudentPhew, they're gone... I thought they would be more wound up about this, but maybe I should have done different prepping.
• Bugscope Teamyou did great
• Bugscope Teamyou did great as jon says
• StudentMaybe 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 Teamoh cool
• Bugscope Teamdeb, 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
• StudentThey were the ones asking questions! Did you think that spelling was me????
• 3:10 pm
• StudentI need to figure out how to log them in
• Bugscope Teamtrue, and like cate says, not everyone has access to so many computers.
• Bugscope Teamah, no deb, i'm a terrible speller myself, so i don't judge others on it ;)
• StudentWe were using one computer. Would it have made sense if everyone had a computer?
• Bugscope Teamwhen you login as teacher, then any other person who logs in will only have the option to login as a student
• StudentWe used a projector up on the wall
• Bugscope Teamah yes, if you have only one computer, then it's best to have just one login
• Bugscope Teamand a projector, yes, lots of teachers use a projector as well
• StudentOK so next time I will have every kid on a computer and you will have bugs from Dresden. Thanks Guys!
• Bugscope Teamthank you deb, see you later!
• StudentBu Bye!
• Bugscope Teamciao
• Bugscope Teamsession disabled, rxl stopped, session locked, users logged off.
• Bugscope Teamsession is done, nice one everyone, see you later!
• Bugscope Teambu bye
• Bugscope Teamheh
