• 8:04 am
• Bugscope TeamOkay I will head up in a sec. Please watch for Mrs Hill. She may call the ESEM phone no.

• 8:12 am
• Bugscope Teamhello mrs. hill!
• Bugscope TeamMrs Hill!
• Bugscope TeamShe's back!
• Teacherhi there!
• Bugscope TeamWelcome to bugscope!
• Bugscope TeamThis is a wasp claw, lying against one of its other arms.
• Bugscope TeamCan you see it alright? Is everything working so far/
• Bugscope Teamfar?
• Teacherwe still have a few minutes before students will be here. how do i change to "full screen"?
• Bugscope Teamhit the box in the top right corner of your explorer window.
• Bugscope Teamthat will maximize your IE window.
• Bugscope Teamyou cannot make the ESEM image full screen, it has to run inside the browser window, with the controls and chat beside it.
• Bugscope Teamhow are the kids going to see this? are they using their own computers or are they watching from yours?
• 8:18 am
• Teacherwe have a white board, so the entire class can see the screen
• Bugscope Teamcool.
• Bugscope TeamAh great. Yeah we don't have a way to separate the image from the rest of the interface.
• Bugscope TeamIt used to be the other way.
• Bugscope TeamMrs H do you want to try a preset?
• Bugscope TeamPlease also be sure to let us know when the kids have questions.
• Teacheryes
• Bugscope TeamIs it just you and the class or do you have an assistant?
• Bugscope Teamgo ahead and click on a preset, the image should change, maybe try controling the mavigation a bit too, get used to it.
• Teachereveryone is here and waiting anxiously
• Bugscope TeamYou should be able to simply click on one of the presets to the right, and the 'scope should go to that place.

• Bugscope Teamnow if you want Mrs Hill you can change the magnification, using the control, top right
• 8:23 am

• Bugscope Teamwhen you try navigating, start with click to center first. that is easier and should work better with the slower connection speed.
• Bugscope Teamit looks like the preset moved since we set it.

• Bugscope Teamhey hey a little late
• Bugscope Teamsometimes, when you want to get your bearings, it's good to go to lower mag, see where you are
• Bugscope TeamHi Annie!
• Bugscope Teamfeel free to ask any questions about the images of the bugs, and we will try to answer.
• Bugscope TeamAnnie is our entomologist.
• Bugscope TeamAnnie there is a super large wasp on here, a smaller one with an entended abdomen, an ant, and a moquito.
• Bugscope Teamok, cool
• Bugscope Teamyeah mojito -- mosquito -- there we go.
• TeacherWe are excited to have a real entomologist!!

• Bugscope Teamhahahaha

• Bugscope TeamI am always excited for bugscope!
• TeacherWhat kind if bug are we looking at?
• Bugscope Teamnow we see one of the claws, and a folded leg/arm, and the background with carbon tape and silver paint
• Bugscope Teamthis is a wasp
• Bugscope Teamthe body is to the left.
• Bugscope Teamthe "hairs" on it are called setae.
• Bugscope Teamnot far, 'cause you can see a wing below this
• 8:28 am
• Bugscope Teamif you decrease the magnification a bit and move to the left you may be able to see the more familiar parts of the insect
• Bugscope Teamyou have to click to stop!
• Bugscope Teamyes, but mrs. hill, please try using click to center when navigating, you might have an easier time with it.
• Bugscope Teamthis is a hard feature to use.

• Bugscope Teammrs. hill, your connection speed is too slow for driving. please use click to center instead. cool!
• Bugscope Teamyou can always click on a preset to get back to a nice location.
• Bugscope Teamright here we are looking at the area between the wasps wing (left) and its abdomen (right)
• Bugscope Teamnow you can see the abdomen on the right, and a wing on the left

• Bugscope Teamthis is a wasp, still, and I am way behind Annie
• Bugscope TeamI don't how I beat you...
• Bugscope TeamI think we see the hamulae, or whatever they're called -- the wing hooks -- on the wing section that is next to the abdomen
• TeacherHow cawe tell if this bug is a male or a female?
• Bugscope TeamIn paper wasps like this one, most of the wasps that you find are females
• 8:33 am
• Bugscope Teamsome four-winged insects, like this one, have the ability to hook fore- and hindwings together when they fly

• Bugscope Teama stinger is a modified ovipositor
• Bugscope Teamcool, good click to center mrs. hill!

• TeacherWhat are we looking at?
  Bugscope TeamThis is the edge of a wasp's wing
• Bugscope Teamusually an ant has two combs like this, and wasps are also hymenoptera; here we see the same combs.
• Bugscope Teamin the center, below, we see part of the one of the limbs as well
• Bugscope Teamwith little antennae comb on it

• Bugscope TeamMrs Hill please try another preset if you would like.
• Bugscope TeamThere's more stuff to see.

• 8:38 am
• Bugscope TeamThis is the claw of a very large wasp.
• Bugscope TeamThe end of the tarsi.
• Bugscope Teamtarsi is like an apendage, like a hand, right annie and scott?
• TeacherHow old is this wasp? ...and how long do they live?
  Bugscope TeamA large wasp like this will usually live a month or two
• Bugscope TeamYeah the tarsi are the last few segments of the arm -- like a whole bunch of forearm segments.
• Bugscope Teamit sat on my desk for a month at least

• Bugscope TeamThere are some wasps like this that do hibernate over the winter as adults though

• Bugscope Teammaybe it was sleeping and I didn't realize it
• Bugscope Teampretty sure it wasn't, it didn't wake up with an ethanol bath
• TeacherWhat are the little ball-like particles in the hairs?
  Bugscope Teamprobably just dust and dirt
• Bugscope Teamhaha
• Bugscope Teamlike the blues song
• 8:44 am
• Bugscope Teamin some cases the ball-like particles, if they are regular, are brochosomes

• Bugscope Teamyeah but those don't look like them

• Bugscope TeamSometimes the ball-like particles are pollen, also
• Bugscope Teamthere are brochosomes on other samples here

• Bugscope Teamthis is a great detail of the cuticle -- of the chitin exoskeleton of the arm here
• TeacherWhat are brochosomes?
  Bugscope Teambrochosomes are little proteinaceous particles produced by some leafhoppers. Leafhoppers brush them over their egg masses to protect them from drying out.

• Bugscope Teambrochosomes are tiny, often round, waxy particles that are produced exclusively by leafhoppers.
• Bugscope Teamthe round ones look like little soccerballs, like here above you can barely see one

• Bugscope Teamthey are generally a few hundred nm across

• Bugscope Teamhere they are on the ocellus of one of the wasps
• Bugscope Teamone of the ocelli
• TeacherJames D says this is the eye. Is he right?
  Bugscope Teamyes- a compound eye at that
• Bugscope Teamthis is one of the accessory eyes, yes, for sure
• 8:49 am
• Bugscope TeamYES!
• Bugscope Teamnow you can see the edge of one of the compound eyes

• Bugscope Teamthe compound eye has tiny facets you can see now, called ommatidia
• TeacherAre the specimens coated in silver?

• Bugscope Teamthey are coated in gold-palladium, but we put down silver paint before we put down the insect
• Bugscope Teamthe gold-palladium makes the sample conductive so that when we beam electrons at it they are shed to ground
• TeacherCan you explain why this process is done?

• Bugscope Teamthe electrons we beam at the sample cause secondary electrons to come out of the surface of the sample, or the conductive coat on the surface, and the secondarry electrons give us the images we see
• Bugscope TeamOOF

• Bugscope Teamwe use a sputter coater to put a very fine coat of gold-palladium on the sample -- the coat is a few nm thick
• Bugscope TeamOOF= out of focus if scott didn't already mention that

• 8:54 am

• TeacherAre we actually moving the microscope, or are you responding to our commands?
• Bugscope Teamyou are moving the scope yourself!
• Bugscope Teamwe are only watching.
• Bugscope Teamyou are controlling the microscope from your classroom
• Bugscope Teambut sometimes we dink with it while you are using it

• Bugscope Teamthis is why it requires a somewhat decent internet conneciton, we are sending ESEM images over the internet, and you are controlling those images from your browser window.
• Bugscope Teamthe system is designed so that you can control it over the internet

• Bugscope TeamOK people sorry to duck out. We have lab meeting followed by class. Have fun!!!
• Bugscope Teamawww
• Bugscope TeamThanks Annie!

• Bugscope Teamthe image is drifting out of focus
• TeacherThank you very much???
• Bugscope Teamyou can take the mag down -- go to a lower mag -- and see where you are if you like
• 8:59 am
• Bugscope Teamannie is leaving, that's all. keep going mrs. hill.
• Bugscope TeamAnnie had to go to a lab meeting, so we lost her.

• Bugscope TeamBut we're good here.

• Bugscope Teamthe images are black and white because we are using electrons rather than light to view the samples

• Bugscope Teamnow we see the face of the ant

• Bugscope Teamif ant's could look in the mirror, this is what they'd see.

• Bugscope Teamyou can barely see the eyes, which are back further on the head.
• TeacherDo all stinging insects have poison on the end of their stingers?
• Bugscope Teamnow we see on of the limbs, and to the fore we see tarsi

• Bugscope TeamI think that is true Mrs Hill, if they are really stingers.

• Bugscope TeamSometimes ovipositors look like stingers, and they are egg injectors

• TeacherWhat is the tarsi?
• Bugscope Teamthe poison travels through inner ducts to the tip of the stinger
• Bugscope Teamtarsi are the last several segments of the arm, culminating often at the claw
• Bugscope Teamthe tarsi is likean apendage or hand.

• 9:05 am

• Bugscope Teamnow we are looking at the toothlike portion of the ant jaw.

• Bugscope Teamthis in the image now is dirt, with a lot of fungus
• TeacherIs that food in its mouth?
• Bugscope Teamit could be food, or the remnants of food
• Bugscope Teamyou can see that the jaw is hinged like a gate
• Bugscope Teamcool
• Bugscope Teamthank you class, hope you enjoyed it!
• Bugscope Teamsee you soon mrs. H
• 9:17 am
• Teachergood morning mrs. clarks class is here
• Bugscope Teamhello, welcome to bugscope!
• Bugscope TeamGreat!

• Bugscope Teamnow we can see the whole ant head and the top of its body.
• Bugscope Teamwe have two wasps, a mosquito, and this ant this morning
• Bugscope Teamthe wasps and ant are related; they look similar
• Teacheris our speciemen alive or dead?
  Bugscope Teamall the insects are dead, we hope
• Bugscope TeamHymenoptera.
• Bugscope Teamthe bugs are pretty much dead. coatted with gold-palatium, and sealed in a vacuum.
• Bugscope TeamThese are all dead or we wouldn't be able to image them very easily.
• Teacherwhy are they pretty much dead?
• Bugscope TeamThey would have to hold very still,
• Bugscope Teami meant, dead.
• Bugscope Teamplus they are in a vacuum chamber
• Teacherhah
• Bugscope Teamso if they were not dead to begin with they would soon run out of oxygen,

• Bugscope Teamif the bugs moved, it would be impossible to take good images of them in the ESEM. so, we need dead bugs.

• TeacherWhat is on his face?
• Bugscope TeamThey could just close their spiracles and wait until they could breathe again.'
• Bugscope Teamlot of dirt and some fungus
• 9:22 am
• Teacherwhy does it look like hair?
• Bugscope Teamthe tiny hairs are setae, mostly sensory (mechanosensory) setae.
• Bugscope Teamsome setae are chemosensory
• Bugscope Teamhairs are for mammals and setae are for insects
• TeacherHow can we still see the image if its coated in gold?
• Bugscope Teamthe coat is very thin, just a few nanometers
• Bugscope Teamwhat you are seeing are electrons in the gold that are bouncing off the bug when an electron beam hits it.
• Bugscope Teamso it is a very fine coating that covers the features just barely

• Bugscope Teamwe are choosing the areas (actually you are) where the electron beam scans across the sample
• Bugscope Teamif we choose a small area we get the image of a small area (high mag), and if we choose a large area we get the image of the large area (low magnification)

• Bugscope Teamthis is a comb on the arm of a wasp
• Bugscope Teamthis is one of two comb-like structures on two of the arms of the wasp
• Bugscope Teamants also have combs because the two are very similar insects

• Bugscope Teamwe think the combs are used to keep dust off of the antennae
• Bugscope Teamto keep the antennae clean
• 9:27 am
• Bugscope Teamyou can imagine from seeing ants that they use their antennae more than they use their eyes
• TeacherWhat are we looking at?
  Bugscope Teamthis is part of a wasp leg

• Bugscope Teamthis is the arm of a wasp

• Bugscope Teamoh, arm, rather.
• Bugscope Teamoyu can change to a lower mag and/or drive around here, see what is going on.

• Bugscope TeamI could have said leg as well
• TeacherAre we actually moving the microscope
  Bugscope Teamyes, you are controlling the scope live, from your browser windows controls. we are only watching, and correcting the scope is it gets off.
• Teacher?
• Bugscope Teamit's one of the six limbs
• Bugscope Teamyes you are actually driving a $600,000 microscope
• Bugscope Teambut don't worry, you won't break it
• TeacherCan we try?
• Bugscope Teamhere is a picture of the scope: http://www.itg.uiuc.edu/ms/equipment/microscopes/esem/
• Bugscope Teamyes, you can try "driving" or "click to center"
• Bugscope Teamthe samples are in a vacuum chamber and the electron beam is scanning across them, eliciting secondary electrons that give us the images we see
• Bugscope Teamwhen driving, make sure to click to start driving, then click AGAIN to stop driving.
• Bugscope Teamit
• Bugscope Teamclick to drive doesn't always worth as smooth as it should, so sometimes it is just better to use click to center to get around
• Bugscope Teamis easier to see where you are going if you take the mag to a lower level

• Bugscope Teamnow click the mag down

• Bugscope Teamif you are at such a high mag it is hard to tell where you are

• Bugscope Teamfrom here you should be able to try to focus
• Bugscope Teamwe want this to be a little difficult, as it is for us
• Bugscope Teamcool, this is a compound eye now.
• TeacherHow powerfull is the microscope?
  Bugscope Teamit can magnify up to 600K times.
• Bugscope Teamnow you can see the surface of an eye
• 9:33 am

• Bugscope Teamor more even.
• Bugscope Teamwith a perfect sample we have 2-nm resolution
• Bugscope Teammeaning that we can differentiate between two small objects that are 2 nm apart

• Bugscope Teamyou are doing a good job, and it is not so easy
• Bugscope Teamnow you see the head of the wasp, and the antennae to the right
• Bugscope Teamthe body is to the left
• Bugscope Teamwe tried to make the bugscope experience realistic. the controls are much like it is to drive the scope in reality.

• Bugscope Teamthe eye is large and complex because the flying insects, of course, need to be able to see pretty well

• TeacherWhat could we see at 600,000 magnification coated with gold?
• Bugscope Teamthere are three accessory eyes, the ocelli, between the compound eyesm and smaller
• Bugscope Teamthere is not much to see at that mag

• Bugscope Teammaybe some brochosomes up close

• TeacherWhy isen't there color?
  Bugscope Teamcolor is sensed by wavelength of light, but the ESEM images are gathered using electrons, which are smaller than the wavelegth of light, so no color.
• Bugscope Teamwe are using electrons rather than light
• 9:38 am
• TeacherWhat are brochosomes?
• Bugscope Teamthe electron beam is 2.1 nm in diameter now, and the wavelengths of visible light are 400 to 700 nm.

• Bugscope Teambrochosomes are tiny (a few hundred nm in diameter) particles that are produced only by leafhoppers

• Bugscope Teamthey are thought to protect the eggs of the leafhoppers from drying out
• TeacherWhat is the purpose of the hairs?
• Bugscope Teamthe hairs, which we are supposed to call setae, help the insect feel its surrounding through its exoskeleton
• Bugscope Teamhairs on an insect are called setae because they are not mammals
• Bugscope Teamand they are like "nerve-endings" so that they can sense what is around them
• Bugscope Teamsense its surroundings, actually -- some of the setae are mechanosensory and some are chemosensory

• Bugscope Teamso some of the tiny hairlike things can be used to detect smells

• Bugscope Teamthis is the shaft of the antenna of the big wasp
• TeacherWhat are we looking at here?
• 9:43 am
• Bugscope Teamit will have sensory setae on it for sure
• Bugscope Teamso this is one, pretty much, segment of the antenna
• Bugscope Teamyou can move closer if you wish, and you can adjust the focus
• Teacherwhy does an aentenna need setae?

• Bugscope Teamyou can also go to the mosquito using a preset

• Bugscope Teamthe setae are what make the antenna work properly
• TeacherThank you we need to work on our projects now! mrs. clark will see you wednesday
• Teacherthanks again!
• Bugscope Teamsome of them are just mechanosensory, but there are many that are used to sniff the air for chemicals
• Bugscope Teamthanks class! you all rock.
• Bugscope Teamthanks mrs. H
• Bugscope TeamThank You!
• Bugscope Teamhope you guys had fun!
• Bugscope TeamIs that it for today?
• Teacher:)
• Bugscope Teamsee you Wednesday at about noon!
• Teacheryes that is it for today! ...you cannot stay for antoher 40 min can you....instead of Friday?
• 9:48 am
• Bugscope TeamSure we can stay.
• Bugscope TeamWe usually keep an extra hour on either side of the session. So if you want to explore or let other people drive and ask questions, no problem at all.
• Teacherthat would be so much easier for me and my planning..thanks!!! Class starts at 11:00
• Bugscope TeamIt would be nice if you could go to check out the mosquito.
• Teacheroops, I meant 10:00
• Bugscope Teamah cool. i can stay too.
• Bugscope Teamyou are welcome to drive around and prictice more mrs. H, if ya want to.
• Bugscope Teamwe have the 'scope signed out 'til 11, so cool.
• Bugscope Teammrs. H, scott is going to control the scope, make some new presets.
• 9:54 am

• Bugscope Teamscott is ready for you again mr.s H, we made 3 new presets for ya!
• Bugscope Teamscope is ready for you, i meant.
• 9:59 am
• Bugscope Teamscott is still doing some last minute adjusting....
• Bugscope Teamok, now we are ready.

• Teachergreat..class iis getting ready to start..thanks of radjusting yoru schedule. I did send in Friday insects....can you pre set those??
  Bugscope Teambut preping bugs in the scope takes time, the scope vacuum has to work, and that all takes about an hour at least. so the next session, we'll have your bugs then.
• Bugscope Teamwhen we get those insects we will make a completely fresh sample stub.
• Teacherthese are not my students insects?
• Bugscope Teamwe don't like to re-use stubs because we want each participant to see new critters
• Bugscope Teamin this case yeah we don't have the ones you sent yet
• Teacherokay!
• Bugscope Teamwelcome to bugscope!
• Bugscope Teamright now we are imaging one of the joints of the arm/leg of a very large wasp
• Bugscope Teamsome of the spines at the joint have fallen out or broken off
• TeacherThe bell is about to ring, so I will get them started here in just a moment!
• 10:04 am
• Bugscope Teamok
• Bugscope Teamthe spines here may allow the wasp to feel when its limb is bent at the wrong angle or hyperextended.
• Bugscope Teamwaitign for the class bell, i remember that horror...
• Bugscope Teamjust kidding of course, i loved school ;)
• 10:10 am
• Teacherwe are here
• Bugscope Teamwelcome to bugscope!
• Bugscope Teamwe are ready for ya

• Bugscope Teamyou can see some strands of fungus along with the wasp limb here
• Bugscope Teamnice, you can see where the spikes broke off the joint. pretty cool.
• Bugscope Teamthis is where a few of those big spines had broken off, oops, as Alex says
• Teacherwhy is this pink strip across the image
• Bugscope Teamhmm, try hitting refresh, that sounds like a problem in your image.
• Bugscope Teamit may be because the image is not fully loaded
• Bugscope TeamF5 to refresh
• Bugscope Teamit's like a line across the image?

• Bugscope Teamlet us know if/when it goes away

• Bugscope Teamsometimes the image might not fully load, or the data might get stuck in transport. F5 should fix most errors like that.
• Teacherits gone
• Bugscope Teamcoolness.
• Bugscope Teamwe noticed when we were testing that the connection speeds are sometimes a little slow with Mahomet
• Bugscope Teamit's cool how much detail there is in such small components of the body of the wasp
• Teacherwhat is the big balack hole?
• Bugscope Teamthat is where a spine used to come out, but broke off. looks pretty gnarly huh?
• Bugscope Teamthe hole is where one of the spines/spikes had been
• Bugscope TeamHi Zandra!
• Bugscope Teamhi zandra!
• Teacherhi Zandra
• Guesthi
• 10:15 am
• Bugscope TeamBe sure to check out the mosquito presets and drive around there if you would like, Mrs Hill.
• Bugscope Teammrs. hill, zandra is just a guest, it is your session, so feel free to go as normal.
• Teacherwhy are these images black and white
• Bugscope TeamZandra this is a connection with Mahomet-Seymour High School.
• Bugscope Teamcolor is sensed by the wavelength of light, but the ESEM images are gathered from electrons, which are much smaller than light.

• Bugscope TeamThe images are black and white because we are using electrons rather than light to see the samples
• Bugscope Teamso, all Electron Microscopes can only "see" in black and white.
• Bugscope Teamall of those are brochosomes, which are produced only by leafhoppers
• Bugscope Teamif you see images from an electron microscope in color they have been false colored
• Bugscope Teamand since there are no leafhoppers on here, one of the insects has been associating with them it seems
• Bugscope Teamfraternizing with leafhoppers
• Bugscope Teamwe can color the images after the scope takes them, and use elemental analysis to color them, these are some of those colorized images: http://bugscope.beckman.uiuc.edu/diversions/gallery.htm
• Teacherwhat are broncheosoames?

• Bugscope Teambrochosomes are usually just a few hundred nm in diameter
• Teacherbut what are they?
• Bugscope Teamwe think the leafhoppers use them to coat their eggs to keep them from drying out
• Bugscope Teamthey are proteinaceous balls, probably selfassembled
• Bugscope Teamsometimes they are oval

• 10:21 am

• Bugscope Teamleafhoppers have an 'anointing' behavior in which they spread them on their bodies
• Bugscope Teamfrom wikipedia: they are microscopic secretory granules produced by leafhoppers.
• Teacherthats very interesting
• Bugscope Teamthey are kind of waxy

• Bugscope Teamyou can see scales now, and that tells us we are looking at part of the mosquito
• Bugscope Teammosquitos, butterflies, moths, skippers, and silverfish have scales
• Bugscope Teamfew other insects have scales
• Teacherso this is the mosquito then?
• Bugscope Teamscales are sort of analogous to feathers
• Bugscope Teamyes it is
• Teacheruber coolness
• Bugscope Teamtop right
• Bugscope Teamyeah we think it is cool as well -- so much fun
• Teacherwhat do the mosquitos use the wax for?
• Bugscope Teamthis one was apparently very close to a leafhopper
• Bugscope Teammaybe it was in the same collection vial
• Teacherwhat are the spike looking things at the top right?
• Bugscope Teamsometimes we see brochosomes on the claws of a ladybug, and we know the ladybug probably ate the leafhopper.
• Bugscope Teamthose are probably sensory setae
• Teacherfantabulous
• 10:26 am
• Bugscope Teammechanosensory setae as opposed to chemosensory setae

• Bugscope Teamthe deal is that insects have an exoskeleton -- they don't have skin with nerve endins in it like we do. And they need to be able to sense what is outside the cuticle -- the chitin
• Bugscope Teamendings..
• Teacherare these broncisones
• Bugscope Teamso they have these setae that stick through the chitin and help them feel/sense their environment
• Bugscope Teamyeah we have not seen this many on most leafhoppers
• Bugscope Teambe sure to check out the mosquito eye -- another one of the presets
• Bugscope Teampreset #4
• Bugscope Teamthe presets are places we have found before the session, but they are real places -- they are not stored images

• Bugscope Teamso sometimes they move
• Bugscope Teamthis is the head of an ant

• Bugscope Teamthis ant is pretty good looking, wouldn't you say. nice, clear lines, clean features.

• Teacherhow big is this ant?
• 10:31 am
• Bugscope Teamwell it's mouth is a little dirty
• Bugscope Teamit was about 8 or 9 mm long
• TeacherWhat is in its mouth?

• Bugscope TeamThis is mostly fungus, we think, and some dirt.

• Bugscope TeamOOF
• Bugscope TeamI focused a little for you.
• Bugscope TeamOOF = out of focus.
• Bugscope TeamBut I fixed it DaddyO.
• 10:36 am
• Bugscope Teamah, yes, i just meant to explain what OOF meant.
• Bugscope Teami think we lost mrs. hill. ah, here is clark, welcome!
• Bugscope Teamclark, i just gave you control of the scope.
• Bugscope TeamMrs Clark?
• Teacherhi. we lost you.
• Bugscope Teamyou now have control of the 'scope
• Bugscope Teamplease try going to a preset if you would like
• TeacherThe connection here in Mahomet as gotten slower as the day goes on. Frustrating! This has been a wonderful expereince...the kids love it!!!
• 10:41 am
• Bugscope Teamyes, i'm sorry about the connection, but there is not much we can do from our end. sending images over the internet takes bandwidth.

• Bugscope Teamthis is the edge of the mosquito wing
• Bugscope Teamwe like to see 80-100K/sec, in mahomets case, it's more like 20-50K/sec.
• TeacherI am using a smartboard...which allows for this to be very interactive with the students. This has beena great activity. Several kids were able to participate!
• Bugscope Teamyou can see some of the scales -- they look different than the other scales
• Teacherit does look like feathers
• Bugscope Teamyou can also see microsetae on the wing surface
• Bugscope Team I think they add surface area to the wing and help with lift
• Bugscope Teamto an insect the air is very thick, like water feels to us
• Bugscope Teaminsects are often hairier than we expect, and often dirtier
• Teachergorss
• Bugscope Teambut they are usually already dead when we get them, so some of the dirt and fungus came along after they died.
• Teacheroops, I meant gross
• Bugscope Teamyou can change the mag if you want, and you can drive around
• Bugscope Teamgot it
• TeacherWell guys...our class is over. We will be back in touch on Wednesday.
• TeacherDo you have our insects for that session?
  Bugscope Teamyes, we'll have those for wednesday!
• Bugscope Team Thank you.
• Bugscope TeamWe will have them -- we expect Mrs Hill's husband to be bringing them today.
• Bugscope TeamIf this is a separate set let us know
• Bugscope Teamsjrobin@uiuc.edu
• 10:46 am
• Bugscope Team217 265 5071
• Bugscope Teamok. looks like the session is over, clark may have left (closed the browser window)
• Bugscope Teamzandra, you wanna try driving bugscope?
• Bugscope TeamZandra if you would like to drive or look around you are welome to.
• TeacherThanks and have a great day. The students loved this experience!
• Bugscope Teamthanks mrs. clark! see you wed.
• Bugscope TeamThank You!
• Bugscope Teamglad the students liked it.
• Bugscope Teamzandra may be away from keyboard.

• Bugscope Teamscott, want me to keep the session open for ya?
