• 9:15 am
• Bugscope TeamHOORAY!!!

• Bugscope Teamannie!
• Bugscope Teamwhat's up coolie!

• 9:25 am

• 9:30 am

• 9:36 am
• Bugscope TeamSpider!

• 9:42 am
• Bugscope Teampresets are done, we are ready!
• Bugscope Teamsession is unlocked
• Bugscope TeamThese neighbors have similarly small lawns. People in California just want to use gasoline all the time. These same people have giant shiny American trucks on lift kits.
• 9:48 am
• Bugscope TeamGood morning!
• Bugscope TeamWelcome to Bugscope!
• Bugscope TeamYou may drive whenever you want.
• Bugscope TeamAnd let us know when you have questions. That's what we're here for.
• Bugscope TeamCate put a nice sample together and made some cool presets to help you get started.

• Bugscope Teamwe included the following "insects" for you today: 2 beetles, 1 true bug, 1 leafhopper, 1 spider, 1 male mosquito, 1 wasp, and 1 rolypoly
• Bugscope TeamBug Watcher let us know if you have any problems.
• 9:55 am
• Bugscope TeamIf you all have any questions about specimens that didn't make it onto today's stub, you can ask those questions as well. I know you all were interested in learning about ticks.
• Bugscope Teamhello questioners!
• Bugscope TeamHello Questioners?
• Bugscope Teamwelcome to bugscope
• 10:02 am

• TeacherHi we are here! We are a group of about 80 7th graders - half of us are here right now!
• Bugscope Teamwow big group!
• Bugscope Teamcool, well, welcome to bugscope

• Bugscope Teambug watcher, you have control of the scope now, feel free to drive around, and ask any questions
• Bugscope TeamWow. Feel free to cruise around, and let us when you, y'know, have, like, questions.
• TeacherWhy is it in black and white
  Bugscope Teamthe microscope doesn't use light to get the image, it uses electrons instead. since color is a function of light (the frequency) and since the scope doesn't see light, that's why no color

• Bugscope Teamthis is one of the palps at the edge of one of the jaws

• Teacherwhat is the hair?
  Bugscope Teamthose hairs are called "setae" (see-tee) and they help insects to sense their environment. insects have TONS of setae all over them. they are like cat whiskers in a way.
• TeacherWhat are the spikes

• Bugscope Teamthe samples we are looking at are inside a vacuum chamber, and we are beaming electrons at them. the images come from the electrons that are knocked out of the sample surfaces.

• Bugscope Teamthe deal with insects is that they have exoskeletons -- their 'bones' would be on the outside of the body, unlike ours

• Bugscope Teamit's like if you were wearing a suit of armor -- you would have an exoskeleton
• 10:07 am

• Bugscope TeamThe spikes and hairs stick out of the exoskeleton, and connect with the insects nervous system. The hairs help the insect to feel what is going on outside.
• Bugscope Teaminsects don't have skin like we do. instead they have a hard exoskeleton, and that exoskeleton can't feel things. so that's why they need those setae, which stick through the exoskeleton to nerves underneath, that's how they feel things...

• Bugscope Teamthis is the spider's jaws!
• Teacherwhat kind of spider
• Teacherwhat are we looking at on the spider/

• Bugscope Teamthe things in front were the fangs

• Bugscope Teamwe don't know what kind of spider it is -- it was dead on the floor the other day, a little dried out

• Bugscope Teamnow you can see the fangs

• Bugscope Teamspiders have soft bodies, and they shrvel when they die; it is often hard for us to tell what kind of spider it was
• Teacherwhy do spiders have so many eyes

• Bugscope Teamsome of the setae (hairs) can be mechanosensory (feel movement), other setae can be chemosensory (sense chemicals and smells), and even others can be sticky, or have attraction properties like tenent setae do. (help insects climb walls)
• 10:12 am
• Bugscope Teamprobably helps them have a little better peripheral vision, and also lets them sense motion more easily.

• Bugscope Teamthis is a boy skeeter
• Teacherhow can you tell it is a male?
  Bugscope Teammales have ornate antennae, and their mouthparts are different
• Teacherwhy are the antenna hair
  Bugscope TeamThe little hairs on the antennae are used to sense very very delicate sound vibrations. That is one of the ways that male mosquitos locate females.

• Bugscope TeamSome of the spider's eyes probably also sense things like day length and time of day.
• Teachertell us about the mouthpart
  Bugscope TeamThe biting portion of the female mosquito is inside the proboscis, which is like a sheath.

• Teacherwhy are thier eyes so big?
  Bugscope Teamwell, those eyes are compound eyes, each bump is a unique eye called an ommatidia, and each one has a lens in it. the compound eye is made up of hundreds of these ommatidia, which help the spider to see it's environment, find food, sense movement, etc.

• TeacherHow big are the hair on the antennae
  Bugscope TeamThey are very small, in "real life" they look like fuzz.
• Teacherwhy are the eyes indented?
  Bugscope TeamInsects dry out once they die so they end up all shriveled or shrunken usually
• Bugscope Teamin the insect world, it's all about surviving, what the next meal is going to be, etc. so anything that aids in that survival will probably find it's way onto the insect
• Teacherany driving suggestions for me - I'm having trouble moving around with my mouse
  Bugscope Teamwe could drive for you if you prefer? although it seems like you are doing a good job!

• Bugscope Teaminside the sheath is a set of mouthparts that are closely appressed, like a bundle that includes a tube and four cutting laciniae
• Bugscope Teamit can be tough controlling the microscope from a computer, especially if the internet speed lags the browser image some

• 10:17 am

• Bugscope Teamthe tube injects a little saliva, from one narrow channel, and pulls blood in through a channel with a larger bore, or larger internal diameter

• TeacherWhy is the polen spike
  Bugscope TeamThe pollen is spikey so that it sticks to things...like hairs on little insects. The insects move the pollen around, from plant to plant--which is good for the plant since plants have a hard time walking around.

• Teacherwhat do they use the claws for?
  Bugscope Teamto hold onto food, or grab something they need to move, it's a multi-function device... :)
• Teacherwhy do the claws have creases on them?
  Bugscope Teamsome claws do not have obvious creases, and some do. As Cate says they may help with gripping. Note also that something that is fluted like that is naturally stronger than something smooth.
• Teachercan you tell us abougt the bright spots on the pollen
• Bugscope Teampollen are more useful if they stick to their target in the flower, so if they are spikey, that helps them stick
• Bugscope Teami think they will clean themselves with claws as well?
  Bugscope TeamYup, claws are for cleaning too. They are like a Swiss army knife.

• Bugscope Teamthe claw has texture to help it grab onto things

• Teacherwhat are we looking at
  Bugscope Teamthis, now, is the abdomen of this beetle

• Bugscope Teamnow we see the leafhopper, so very cute, in a way

• 10:22 am

• Teacherare we looking into its mouth
  Bugscope Teamyou are near the mouth. this insect has a tube that it uses to feed through, so it doesn't have our kind of mouth
• TeacherWhy is the hopper so hairy
  Bugscope Teamall insects have lots of hairs (setae), then help them feel their way around the world
• Teacherhow many mouth parts does it have?
  Bugscope TeamInsects generally have about 10 mouthparts total, depending on what you want to consider a mouthpart--but there are lots of modifications, especially in leafhoppers with have all their mouthparts modified into a tube that they use to suck plant juices.
• Teacherare we looking at plaque?
  Bugscope Teamsometimes when bugs die, hemolymph, which is their 'blood,' comes out and dries

• Teacherwe see a tiny hole on our left side of the mouth - ?
  Bugscope Teamwhat is interesting is that we don't always know just what we are seeing -- sometimes people have not looked closely at every insect and have not yet named everything you see using an electron microscope -- or they have and very few people know it

• Teacherare there setae on the eye as well
  Bugscope Teamyes there are! on fruitflies you will see lots of them, and on bees
• Bugscope Teamsee how the center of the head is ribbed? that is like the base of the pumping apparatus that allows the leafhopper to suck up plant juices
• Teachercan you tell us about each facet of the compound eye
  Bugscope Teameach facet is called an ommatidia, with a lens in it. the facet is stationary, and the lens can't move around in the facet like human eye's can. so that's why they have some many facets pointed in a 180 degree area, so they can have side vision
• 10:28 am

• TeacherHow big are the segments of the eye
  Bugscope Teamcheck out the scale bar on the lower left of the image, if you zoom in on an ommatidia, you can measure it's size

• Bugscope TeamThe setae on the eye helps the bee or fly to sense direction and "steer" in the wind. If you shave the hairs off, the insect can't figure out which way to go when they are flying into the wind.
• Bugscope Teamone um = one micron = one millionth of a meter
• Teacherare we seeing dust on the eyes as well?
  Bugscope Teamyes!
• Bugscope Teamif you click on the scalebar you will see the magnification, as well
• TeacherDo they have noses
  Bugscope Teamgood question! but no, they don't have noses. they smell through the hairs!!! some of the hairs are chemosensory setae, and they use those to smell

• Teacherhow many segments are there on the eye?
  Bugscope Teamit depends; some insects may have a few thousand individual facets, or ommatidia
  Bugscope Teamdepends on the insect, sometimes we see just 20-30. flying insects usually have a lot more, even in the thousands!
• Teacherwhat sense do the use most
• Teacherwhat is the roly-polys main diet?
  Bugscope TeamThey eat rotting stuff, fungus, bacteria, etc.

• Teacherrolly polly bugs - not insects? how many legs? where are the eyes?
  Bugscope Teamroly poly's are crustaceans, like crabs

• 10:33 am

• Teacherwhat is the line we are looking at
  Bugscope TeamI think that is a crease than runs down the middle of that portion of the mouthpart
• Bugscope TeamWe usually mount insects/arthropods like them on the dorsal side so we can see the legs
• Teacherdoes the roly-poly have fangs?
  Bugscope Teamnot like a spider -- it has jaws but not fangs that would inject anything

• Teacherwhat type of beetle we are looking at?

• Teacherdo beetles bite
  Bugscope TeamMost will try to bite, but they can't because you are too big and they are too small. It is like trying to take a bite out of the wall.

• Teacherwhy all the hairs in the beetles mouth
  Bugscope Teamhairs, or setae, at the surface of the mouth may have more of a filtering function, preventing sand or tiny particles from getting into the mouth
• TeacherDo ladybugs bite people?
  Bugscope TeamYes, if a ladybug lands on a part of your body with softish skin (like your neck or parts of your arm) they can bite. It kind of feels like a little pin prick. The Asian multicolored ladybeetle is a notorious biter.

• Teachercan it only feel stuff in its antennae or can it feel on the rest of its body
  Bugscope Teamif we look around we see that there are mechanosensory setae on most body parts
• 10:38 am

• Bugscope TeamNice!

• Teacherhow do kill the bugs
  Bugscope Teamif we get them live here, or at home, we freeze them
• Bugscope Teamyeah that is so cool-looking, uncommon
• Teacherhow do ticks get under the skin?
• Teacherwhy do the antennae look to have separated discs
• Bugscope Teambut we don't know, I am sorry, just what beetle this is
• Teacherwhat is the stuff that grasshoppers spit?
  Bugscope TeamIt is kind of like puke...they regurgitate it from their crop, which is at the top of its stomach.
• Bugscope TeamIf we zoom out a bit and sort of hover above the beetle, I might be able to tell what it is. The antenna gives me some clues.

• Bugscope TeamAnnie is our entomologist.

• Bugscope TeamI am an electron microscopist, and Alex is our computer whiz.
• Bugscope TeamWhat color was this beetle before it became golden?
  Bugscope TeamAnnie I am not sure. Brown?
• Bugscope TeamCate is also an electron microscopist.
• Bugscope TeamCate made the sample and is out for a little while.
• TeacherHow many joints does the average bug have?

• Bugscope TeamI was afraid you'd say brown.
  Bugscope Teamsorry -- maybe reddish-brown? ;)

• 10:43 am
• Teacherwhat is black spot we are looking at
  Bugscope TeamThe black circle is where this insect was once pinned. This specimen was donated from an entomology class collection
• Bugscope Teamhaha.

• Bugscope Teamouch!
• Bugscope TeamI am stumped on the identity of the beetle. Maybe it will come to me.
• Teacherthese students are creating insect collections here in Montana right now......they feel the beetle's pain
  Bugscope TeamHahah! You are getting an advanced start on your entomology careers!

• Bugscope Teamcool! not the pain part though
• Teacherwhy moth scales in beetle claw
  Bugscope Teamit was probably collected with some other insects, including a moth or butterfly
• Bugscope Teamwe can guess, from the way the tarsi look, that this beetle could not walk on a window
• Teacherwe are very curious about ticks - a big thing here in Montana - can you tell us about how they imbed in our skin
  Bugscope Teamticks have a head capsule called a capitulum, and on either side are palps that fold down so that the mouthparts can penetrate your skin
• Teacherwhy do moths have scales
  Bugscope TeamGenerally speaking, a moths scales are for protection. If you have every tried to catch a moth with your hands you know how slippery they are. They are slippery because of those scales, which easily rub off when the moth is touched. The slippery scales also help the moth escape from spider webs and the mouths of birds.

• Teacherwhy are mothes attracted to light
  Bugscope Teamthe true reason is unknown but there are theories. one theory is they use a technique called celestial navigation to help them fly strait

• 10:48 am

• Teacherwhy can't you feel the tick get uder your skin?
  Bugscope TeamI believe some of them at least have an anesthetizing saliva
• Bugscope Teamthe mouthparts have a side with recurved spines on it that holds into the skin, and the other side has smaller spines of spikes that rasp the skin to cut it and get blood flowing

• Teacherinsects are so cool!

• Bugscope Teamno doubt!

• Teacherhw

• Teacherwhat is the biggest type of beetle?
  Bugscope TeamThe largest beetle in the world is called the Titan beetle. It is found in the Amazon and can be more than 13 cm long.

• Teachergood job thank you
• Teachermason says hi!
• Teacherone of our groups is leaving and the other half is coming in - there will be a slight delay in questions. these kids alls say thank you! and "this is so cool!" and they want to know your personal favoirte types of bug
• Teacherwhen did you know you wanted to become a scientist and why?
  Bugscope TeamI always liked to be outside in the dirt. When I got older, in high school, I realized that I was really good at biology and that I really enjoyed it and that I could make it my job. I knew I wanted to be an entomologist when I was a senior in high school
• Bugscope Teamthank you, you all did great!
• Bugscope Teamwe are ready for the next batch of kids anytime... :)
• Teacherhow did you become an entomologist
  Bugscope TeamI got a degree in biology for my undergrad, then I went to graduate school and got a masters and a PhD in entomology.
• 10:54 am

• Teachercool! we have many budding scinetists here. We currenlty have a pine beetle problem in Montana - aand are studying them in science class
  Bugscope Teamyes, I study wood boring insects as well...not the bark beetle types, the longhorned beetle types.
• Bugscope TeamI started out in English and ended up with a double major in English and Biology. I started to learn electron microscopy in my last year of college. Then I hung around with herpetologists, but I met some entomologists as well.
• Teacheris it only the male mosquito that has fluffy antennae? is the purpose for finding a female?
  Bugscope TeamOne thing about the ornate antennae is that they make a noise the females recognize.
• Teachercool have scientists recorded these sounds?
  Bugscope Teami'm sure they have, but i don't know for sure. i looked online a bit, and didn't find that exact sound, but i found a neat page with tons of other sounds from insects: http://www.ars.usda.gov/pandp/docs.htm?docid=10919
• Bugscope Teamthey make a distinct noise when the air goes through them; they also look pretty and presumably that is an attractive feature as well.
• 11:00 am
• Teacherwhat do male mosquitos eat? it looks like thye have a piercing mouthpart - but we thought they didn't eat blood
  Bugscope Teamthey do not drink blood; it hasbeen said that they drink nectar -- plant juices

• Bugscope TeamI am a little confused about this, but I believe that the females have an organ in their antennae called a Johnston's organ that helps them hear better, including the sound of the male antennae
• TeacherWe're looking at the eyes... do the insects see in black and white?
  Bugscope Teamlikely some of them do see sort of primitively, but many do see in color. not only in color but in the UV as well, which we cannot

• Bugscope Teamthe ommatidia are dried, a bit
• Teacheris that why they are wrinkly
• Bugscope Teamnormally they would be kind of swollen and round
• Bugscope Teamyep
• Bugscope Teamnotice the scale bar in the lower left
• 11:05 am
• Bugscope Teamif you had compound eyes you would see many images; you would also have a very acute ability to perceive motion
• Bugscope Teamone um = one micrometer (micron) = one millionth of a meter... wow!
• Bugscope Teamcompound eyes are also a good way of extending one's vision more peripherally -- closer to 3D -- all around your head
• Bugscope Teamthese ommatidia are pretty big, right scott? i don't think i remember them being 23 microns...?

• Bugscope Teamwe see a hexagonal shape quite often because it is the best way to close pack things that are rounded, and it is also a good way to pack round things that will have a curved surface.

• TeacherWhy do these "fangs " appear hairy?
  Bugscope Teamthe fangs themselves are not hairy, but the chelicers are
• Bugscope TeamI think those are larger that most ommatidia we see -- but we can now compare that diameter with those of the wasp
• Teacherare those all eyes? how many approx?
  Bugscope Teamspiders have 8 eyes. They are mostly covered up right now by dried goop of some sort. The background is carbon tape that is bubbly looking
• Bugscope Teamthose are bubbles in the carbon tape
• TeacherWhat are chelicers?
  Bugscope Teamthey are mouth parts of a spider, used to manipulate food
• Bugscope Teamwe cannot see the eight eyes from this perspective

• Bugscope Teamthose are the two vertical components we see now in the middle

• TeacherWhat is their purpose?
  Bugscope Teamthe chelicers open and drive the fangs into you
• Bugscope Teamthe fangs point toward each other and are almost off-screen now
• 11:10 am
• Teacherdo you know the kind of spider?
  Bugscope Teamno I am sorry -- we are not very good at spiders
• Teacherare the fangs hollow
  Bugscope Teamyes they have ducts inside that deliver venom and also suck out insect innards

• Bugscope Teamyou are doing a great job of controlling the scope bug watcher!
• Teacheri'm finally getting the hang of it
• Bugscope TeamThere is one building on campus that is apparetly infested with recluse spiders. But it is far from here.
• Teacherany idea what is stuck on this hair?
  Bugscope Teamfrass?

• Bugscope Teamhmm, dirt, smudge, or as well call it.... juju

• TeacherHow big is the whole spider?
• Bugscope Teambecause of its rounded shape, this may be frass, what entomologists call poop.

• Bugscope Teamthe spider would have been maybe 2 or 3 cm in diameter with its legs spread out
• 11:15 am
• Teacherwhere are leaf hopper's eyes
  Bugscope Teamyou can see them -- they are like smooth domes on the side of the head
  Bugscope Teamsee the ridged part of the head? There is an eye to the left of it. It is very big and you can only just tell its roundness.

• Bugscope Teamthere!

• Bugscope Teamthe eye has those bits of fungus that look like hair on it
• Bugscope Teamsee it now?
• TeacherOOwhat a coll looking bug! what are the little ridges on its head
  Bugscope TeamI believe the ridges are part of the pump apparatus that pulls the plant juices up through the proboscis]
• Teacherwhy are they eyes so big
• Teacherwhat do leafhoppers eat?
  Bugscope Teamthey feed on sap and plant juices that they obtain using their piercing mouthparts
• Teacherdo they bite?
  Bugscope TeamI'm not entirely sure, but one jumped on me over the summer and it felt like it bit me
• Teacherwhy is it called a leaf hopper
• Teacherdo you know the order?
  Bugscope TeamCicadellidae

• Teacherare those like little grabbers?

• 11:20 am
• Teacheris this the sharp piercing part on the bottom of the proboscis
  Bugscope Teamyes that's it!
• Bugscope Teamyou can see the tip of the proboscis there --
• Bugscope Teamyes
• TeacherWhat type of environment do these live in?
  Bugscope Teamthey feed on leaves on plants, so they are often found in plant areas all over the world, they are a huge family of insect
• Bugscope TeamCate reminded me that the order is Hemiptera -- true bugs.
• Bugscope TeamI guess Cicadellidae is the family, sorry.

• TeacherDo we know if this is a male or female?
  Bugscope Teamwe don't know -- with some insects you can tell right away, and with some you cannot tell until you open them up

• Bugscope Teamhey nice!
• Bugscope Teamgood job driving!
• Teacherhow big is the leafhopper
  Bugscope Teamit is maybe 8 or 9 mm long
• Teachercool look how sharp it is!

• 11:26 am

• Bugscope Teamhere is a wasp, looking at the underside of the head

• Bugscope Teamsee the big curved jaws?
• TeacherWhat are the appedages that seem to be folded across its head horizontally?
• Teacherwhy is the wasp head so hairy
• Bugscope Teamha those are the jaws

• Bugscope Teamthe other appendages are palps, which there are usually four of. The palps help the insect manipulate and taste its food.

• Teacheris this the stinger
• Teacherwhat are the ridge things on the wing

• TeacherCan these guys see behind them... perhaps prey closing in for the delicious kill?
  Bugscope Teamthey have good peripheral vision
• Bugscope TeamYou found the hamuli!

• TeacherDo they have teeth?
  Bugscope Teamthey do not have teeth, but some jaws are hardened with calcium
• Bugscope Teamah, yes, hamuli!

• 11:31 am
• Bugscope Teama lot of flying insects have a total of 5 eyes. 2 compound eyes and 3 simple eyes called ocelli

• Teacherthe students are clamoring for a more descriptive word than "good"

• Bugscope Teamtheir compound eyes will seem to wrap around their heads giving them an almost 360 degree view arou d them

• Bugscope Teamthe hamuli you found on the edge of the wing are little clips that let two wings function like one

• Bugscope Teambees and wasps have hamuli -- they have four wings and have found that it is more efficient to fly with, essentially, two

• Bugscope Teamso they clip their fore- and hindwings together when they fly

• TeacherDo we have a sense for their speed in flight?
  Bugscope Teamfly's are not as fast as one would think, maybe 5 M.P.H top speed?

• Teachergreat hamuli action
• Bugscope TeamI pulled the focus in a little more

• Bugscope Teamit'll show up on your Bugscope home page
• Bugscope Teamnot sure we can see the eyes on this rolypoly

• TeacherWhich tastse better, roly poly leg or king crab leg?
  Bugscope Teamrolypolies are more crunchy -- you don't get to taste the meat

• Bugscope Teamif you all collect earwigs, look for mites

• 11:36 am
• TeacherHow many legs does the roly
  Bugscope Team18, or 28? Not sure I remember. We could count them.
• Teacherp
• Teacherare these setae - or are they more like spikes
  Bugscope Teamthose were the tips of the little pointy legs, weren't they? that is why they are called isopods -- because all of their little feet are alike.
• Teacherhow many legs does the roly poly have?

• TeacherYES!!
• TeacherPlease!

• Bugscope Teamthis is the macro view
• TeacherWhoah! - all students!
• Bugscope Teamthat is a vacuum chamber in there, no air inside!

• Bugscope Teamyou can see the cone-shape, above, where the electrons come from, and you can see the little platter that the bugs are on -- it is 1.75 inches in diameter

• Bugscope Teamto our right is the secondary electron detector

• Bugscope Teamwow this is cool

• Bugscope Teamnow we are back on the secondary electron detector
• Bugscope Teamit's a bunch of pollen grains
• 11:41 am

• Teacherwhat is so special about the hexagonal shape in nature - so cool!
  Bugscope Teamwell, for a compound eye like this one, the hexagons help the shape of the entire eye to be curved, yet the sides of the ommatidia (hexagons) can still remain touching. if the ommatidia were square, then that wouldn't be possible.

• Bugscope Teamnow we can see that the diameters of the ommatidia are not that different from those of the mosquito, here.
• TeacherWhat color are the eyes?
  Bugscope Teamthe eyes of the wasp appear black, or purplish black

• Teacher many eyes tdo they have
  Bugscope Teamthey may have thousands of ommatida -- they have five eyes overall

• Teacher it stacked up ?

• Teacherone setae - cool pic
• Bugscope Team:)
• Teacherdo beetles see in black and white
  Bugscope TeamI think most of them see in color

• Bugscope Teamtheres a bunch of microsetae around it

• Bugscope Teamand some insects can see UV as well

• Teacherthis is so cool! and fun

• TeacherOk - we have to log out now to et kids to their next class. we walked to a local university to use their computer and high speed internet. thanks so much. We all loved it and kids were fired up! Thank YOU !!!!!!
• Bugscope Teamwe enjoy these nice sessions as well, it helps to have such a GREAT class!
• 11:46 am
• Bugscope Teamthank you for using bugscope and we hope you all had fun
• TeacherI'm looking forward to printing off our session and discussing all that we've learned further
  Bugscope Teamyep, check out your member page for all the chat and images: http://bugscope.beckman.illinois.edu/members/2009-102
• Bugscope TeamThank You!
• Bugscope Teamall the chat and images are saved to your bugscope member page: http://bugscope.beckman.illinois.edu/member/2009-102
• TeacherLogging out Thank you agian!
• Bugscope Teamover and out -- I want to beat the nerds to the food
• 11:52 am
• Bugscope Teamnice session everyone. over and out
