- 7:48 am
- Bugscope Teamsession enabled and unlocked, rxl started
- 7:59 am
- Bugscope Teamhello joyce! welcome to bugscope
- Bugscope Teamwe are still setting up, session in 1 hour, right?
- TeacherHi all! Yes, we are still on for the lesson today. Just checking to make sure all is working. See you in an hour.
- Bugscope Teamwe are starting to make presets now, when we are done (about 20-30 minutes) you can practice driving the scope if you want to
- Bugscope TeamHi Joyce!
- 8:08 am
- 8:14 am
- 8:22 am
- 8:28 am
- 8:33 am
- Bugscope Teampresets are done, we are ready!
- 8:42 am
- 8:47 am
- 8:53 am
- Bugscope Teamyay!
- Bugscope TeamHi Joyce!
- Bugscope Teamhi joyce!
- Bugscope Teamthis is cool, right here, where the caterpillar uses Velcro (TM) to connect to a branch
- 9:03 am
- TeacherHello Scot and Alex! We are ready to go!
- Bugscope Teamawesome, you shoudl see controls on the right side
- Bugscope TeamLet us know if you have any questions or any trouble driving.
- Bugscope Teamat anytime you can click on a preset to move to that location
- Bugscope Teamthese are the bugs that you sent us
- Bugscope Teamthese are the scales on a monarch butterfly wing
- TeacherLogan says that these scales look like teeth!
- Bugscope Teamhey, they do!
- 9:08 am
- Bugscope Teamlike molars
- Bugscope Teamif you had that many teeth, you could eat ANYTHING!
- Bugscope Teamif the butterfly gets caught in a web, it can shed some of its scales to get free
- TeacherDevin asks, "How long did it take you to make the scanning electron microscope?"
- Bugscope Teamwell, scott or cate should answer that better than me, but we didn't make it, we bought it from a company
- TeacherSusi asks, " Why do bugs eat other bugs?"
Bugscope Teamwell susi, they only eat them so that they can survive, either by nourishment or some other reason like that
- Bugscope Teamit cost a LOT of money
- Bugscope TeamThe microscope cost $600,000 about 9 years ago, so they are much more expensive now
- TeacherSean asks, "How many caterpillars have you seen through the microscope?"
Bugscope Teamhundreds! probably...
- Bugscope TeamIt was funded through a grant that was geared towards Bugscope
- 9:14 am
- Bugscope Teamthis is a cool image, this is a spiracle, this is how insects breath. instead of a mouth they have holes on the sides of their bodies
- TeacherDorothy asks, "Is there a bug in the whole wide world with wings but can't fly?"
Bugscope Teamthere are quite a few actually. Lots of beetles of wings but don't use them.
- Bugscope Teamthere are lots of animals that have wings that don't fly as well. strange huh?
- TeacherGabe is our first driver.
- Bugscope Teamlike an ostrich or an emu
- Bugscope Teamchickens
- Bugscope Teamyay gabe!
- Bugscope TeamCool! Go Gabe.
- Bugscope Teamthe flea!
- Bugscope Teampenguins also don't fly but have wings
- Bugscope Teamyou can see the eye; this is the tip of the head
- Bugscope TeamHello all!
- Bugscope TeamA flea!
- Bugscope TeamHi Annie!
- Bugscope TeamA flea that was once on me!
- Bugscope Teamyeah this flea is courtesy of Annie
- Bugscope Teamshe was living in the wild this summer
- TeacherShanna asks,"Why are there hairs on the back of it?"
Bugscope Teamthose hairs are called setae (sea-tea) and they are like cat whiskers, they help the bugs to sense their environment
- Bugscope TeamAnnie is our entomologist
- 9:19 am
- TeacherGabe asks, "Where do you put the bugs when you are done with them?"
Bugscope Teamafter we are done with a session, we usually throw them out. Sometimes we will keep a sample or two to show other people
- Bugscope TeamYes, the wilds of Los Angeles CA
- TeacherParker asks,"Do you use the SEM daily?"
Bugscope TeamWe have around 3 bugscope sessions a week. When we aren't using it, other students at the university use it for their research
- Bugscope Teamthe bugs are all coated with gold-palladium but it is so thin that it is not worth keeping
- Bugscope Teamthis is pretty cool -- the mosquito eye
- Bugscope Teamyeah so the microscope gets used every day, even on weekends
- Bugscope Teamthe facets of the compound eye are called ommatidia
- TeacherBrian is our driver now!
- Bugscope Teamgo brian!
- Bugscope Teambrian, you are controlling a $600,000 microscope!
- Bugscope Teamthe eye facets -- the ommatidia -- are a little shrunken. they are more puffed up when the skeeter is still alive
- Bugscope Teamsee how the whole head is covered with ommatidia?
- Bugscope Teamalmost everywhere except the mouthparts and the bases of the antennae
- TeacherEmily asks, "What kinds of bugs do you like?"
Bugscope Teami like roly poly's
- 9:24 am
- Bugscope TeamI like earwigs.
- TeacherMrs. Wratten asks, "What part do mosquitoes bite us with?"
- Bugscope Teamwe like bugs that have special features on them, or things living on them like scott said
- Bugscope TeamAnd some things that aren't really insects, like ticks
- Bugscope Teamyou can see the biting parts on this mosquito
- Bugscope Teamthere is a long sheath covered with scales, and inside it is a stylet, which is very sharp
- Bugscope Teamyou can find that to the left of here i think
- TeacherSarah asks, "Why do mosquitoes drink blood?"
Bugscope Teamonly the female mosquitos drink blood, and it's not like they have to do it for survival (they can get food from nectar and such) but something in the blood helps to increase production of their eggs, so it helps them to reproduce
- Bugscope Teamthe sheath/proboscis has a slit in it
- Bugscope Teamonly the female mosquitoes drink blood, and it is because they need to have energy in order to successfully lay their eggs
- TeacherKaleb is now driving!
- Bugscope TeamCool -- Kaleb!
- TeacherIt reminds us of spaghetti!
- Bugscope Teamthis is a bunch of silk the caterpillar wrapped around the little branch so it could hang its chrysalis from it
- Bugscope Teamso the caterpillar made its own web
- Bugscope Teaminsects other than spiders sometimes make web
- TeacherParker asks, "How do you use your SEM in your work office?"
- Bugscope Teamit is cool to see this today because we can tell how the process works
- 9:30 am
- Bugscope Teamthe SEM is right near our offices, and our job is to help people use it and a number of other microscopes
- Bugscope Teamkaleb, go ahead and click again to stop moving
- Bugscope Teamgood job kaleb!
- Bugscope Teampeople use the SEM, and the TEM (transmission electron microscope), and other microscopes to do their research
- Bugscope Teamthis lab has about 20 microscopes, and many of them have their own rooms
- TeacherPaige asks, "How much do you know about bugs?"
- Bugscope Teamwe learn more about bugs every day
- Bugscope Teamit used to be annie was the only one that knew about bugs. But after doing so many bugscope sessions, we learn more and more about bugs ourselves
- Bugscope Teamit is amazing the things we don't know, but we are very interested
- Bugscope Teami know the least about bugs, scott and cate know much more than me. but it's really cool doing bugscope, i've learned so much
- TeacherAnna wants to know what this is...
Bugscope Teamthis is a little twig that had the monarch chrysalis attached to it
- Bugscope Teamwe have a friendly competition to try and answer questions better and more completely
- TeacherMartin is coming to drive now.
- Bugscope Teamha the beetle
- Bugscope Teamthis guy has some busy mouthparts
- Bugscope Teamyou can see his antennae, and his eyes, as well
- Bugscope Teamnow his legs, and the abdomen
- Bugscope Teammartin, gonna drive like an aston-martin!
- Bugscope Teamsee how his wings are folded up?
- 9:35 am
- Bugscope Teamhis wings are folded under a shell called the elytra
- Bugscope Teamlike a ladybug's
- Bugscope Teamthis might be some sort of seed beetle. they resemble ladybugs
- TeacherAshley asks,"What is the smallest insect in the world?"
Bugscope Teamthat would be a fairyfly i think
- Bugscope Teamthis is milkweed floss that Cate collected
- Bugscope Teamthey are tiny wasps
- Bugscope Teamso we could see what Monarchs like to eat
- Bugscope Teamyes, i think cate is right, it's the fairyfly, which are insects that parasitize other insects' eggs by laying their eggs inside them. eeewwww!
- Bugscope Teamthere are many tiny wasps, and many of them are parasitic
- Bugscope Teammilkweed is often poisonous to other insects and animals. So since the monarch eats it, the butterfly itself is poisonous
- Bugscope Teamspiders are said to know that Monarchs are not good to eat
- TeacherKamryn has bee driving around the seed!
- Bugscope Teamspiders are not insects, by the way, they are arachnids. key difference between insects and spiders is that all insects have six legs, and all spiders have eight
- Bugscope Teamgood job kamryn
- 9:40 am
- TeacherBrian asks, "Where do owl moths come from?"
- TeacherDorothy asks, "What bugs besides Monarchs migrate to Mexico?"
- TeacherThis is another Ashley driving!
- Bugscope Teamso there are different types of owl moths where you live!
- TeacherHeather want to know, "Is there a bug that never eats?"
- Bugscope Teammonarch btterflies are the most famous ones, but other types of migrating insects are locusts, beetles, and dragonflies
- Bugscope Teamsome adult insects do not eat
- TeacherHeeeere comes Susi the lady driver!
- Bugscope Teamgo susi!
- Bugscope Teamthere are some adult insects that do not have mouths
- 9:45 am
- Bugscope Teamlike fugus gnats
- Bugscope Teamfungus gnats
- TeacherJeremy asks, "How do ladybugs lay their eggs?"
Bugscope TeamFemale ladybugs lay tiny eggs, usually laid in a small mass on leaves
- Bugscope Teamthe flea!
- TeacherSarah is the next driver!
- Bugscope TeamGo Sarah!
- TeacherMrs. Peele wants to know where butterflies get their colors?
- Bugscope Teamsome of the colors we see in butterflies are from pigments that can be found in the scales
- 9:50 am
- Bugscope Teamstructural colors come from the shape and pattern of the scales and the way those shapes/patterns reflect light
- TeacherDorothy asks what "structural colors" are...
Bugscope Teamstructural colors happen when light it interfered with in some way, whereas as other colors happen via pigment.
- TeacherSusi asks, "How many of the bugs have you collected all together?"
- Bugscope Teamit's like when you look at the grooves on a record, which is black (usually), but you see other colors reflected
- Bugscope Teamhere is a different kind of spiracle that is on the caterpillar
- Bugscope Teamwe bring bugs to the lab every week in the summer
- Bugscope Teamwe have to save them up for the winter months
- Bugscope Teamthe caterpillar has a soft body, and when it dries it shrivels up
- TeacherDevin is driving.
- Bugscope Teamcompared to the adult insects we have seen that have stiff chitin, or cuticle, that forms the exoskeleton
- TeacherWhat part of the caterpillar is this? Some are saying head and some are saying the eyes.
- 9:56 am
- Bugscope Teamit is the head and the eyes, I think, here
- Bugscope Teamhere you see a couple of simple eyes on the head
- TeacherKamryn asks, "How do you catch the bugs?"
Bugscope Teamwell, sometimes we find bugs in our homes, and catch them with a glass and paper, then put them in a small jar and bring them to work
- TeacherDevin wants to know what is on the screen right now.
- Bugscope TeamYou guys I am sorry I have to go but you are in good hands. Thank you for the great questions and good driving!
- Bugscope Teamwe usually just dead insects we see around our work. Sometimes i will pick up insects i see that are dead in my parking garage
- TeacherLogan is making his way to the steering wheel...
- Bugscope Teamgo logan! logan's run!
- TeacherBye Scot!
- Bugscope Teami'm not sure what this is, cate?
- Bugscope TeamI think this might just be some juju
- Bugscope Teamyeah, you guys are doing a great job of controlling the scope, and your questions are way better than what we usually get
- Bugscope Teamthe preset shifted here
- Bugscope Teamthis is the leg of the monarch
- Bugscope Teamthere are some special setae on it for tasting
- Bugscope Teamtry adjusting the brightness up a bit
- TeacherLogan tried the Monarch taste bud, but it was too dark on our Smart Board. Now he has chosen the beetle head.
Bugscope Teamno problemo, if it's dark, you can use 'adjust' to increase the brightness
- 10:01 am
- Bugscope Teamthere ya go!
- Bugscope Teamnice job logan
- TeacherLogan says that the beetle head kind of looks like a golf ball on its eyes.
Bugscope Teamtotally! those golf balls are his 'compound eyes'
- Bugscope Teamthis beetle is giving us a good stare, he must be upset at us for putting him in the scope
- Bugscope Teamthe reason it looks like a golf ball is because they both use hexagons for the facets. Hexagons are the best shape to make round objects
- TeacherMartin wants to know," Why do some butterflies don't go to Mexico?"
Bugscope TeamThe monarch buttefly has the longest life span among butterflies-- 12 months. Other butterflies have too short a lifespan that they don't need to migrate
- TeacherEmily asks,
- Bugscope Teamthere are so many different kinds of butterfly
- 10:06 am
- TeacherEmily asks, "How do ladybugs eat?"
Bugscope Teamthey grab what they are about to eat (aphids or other small insects) and they use their powerful jaws to start munching away!
- TeacherAnna is curious about your work day, "How long do you work each day?"
Bugscope Teamanna, we work about 8 hours a day, sometime more, sometimes less, based on how much work needs to be done that day
Bugscope Teamanna, working for a university is very nice because people are usually very interested in what they do. just like your teacher!
- Bugscope Teamhere is a nice close-up picture of a ladybug jaw: http://upload.wikimedia.org/wikipedia/commons/0/06/Ladybird.jpg
- TeacherParker is our lady driver.
- TeacherPaige asks, "When you get near a dragonfly, why does it fly away?"
Bugscope TeamIt probably thinks you are too big to eat (because it is predatory) so it probably thinks it is best to fly away because bigger things might it the dragonfly!
- Bugscope Teamwhat we do is we run a multiuser facility. We have lots of instruments like microscopes that students use for their research, and sometimes they need help using them
- Bugscope Teamparker, if you get lost driving, just try click on a preset (lower right)
- 10:11 am
- Bugscope Teamyou are doing a great job!
- TeacherJeremy is interested in how long caterpillars can grow in length.
Bugscope Teami'm looking up that for you jeremy, but i do happen to know that caterpillars have 4000 muscles! (humans only have 628)
Bugscope Teamthe tomato hornworm caterpillar can get up to 5" long.
- TeacherGabe asks, "How many scales are on a butterfly's wings?"
Bugscope Teambutterflies have TONS of scales. I mentioned earlier, they have so many that when they are caught in a "sticky" situation like a spider web, they can shed them to get free
- TeacherDorothy will drive and then how much more time do we have, guys?
Bugscope Teamyou have until 11am our time, which I think is 12pm your time?
- 10:16 am
- TeacherI am going to get the last few questions to you because we only about 5 minutes left before we have to eat lunch. That is very important to second graders!
- Bugscope Teamtotally understand joyce
- TeacherSarah asks, "Where did you get the idea to become a bug scientist?"
Bugscope Teami'm actually a computer fix-it person for the group, i do bugscope so if a computer breaks during, i'm here to fix. scott and cate know much more about bugs than me
- TeacherSusi asks what the nastiest bug has ever been on the Bugscope.
Bugscope Teamsometimes you get these real juicy bugs, which are really hard to view inside the microscope, those are pretty nasty
- TeacherPaige asks, "How long does a lady bug live?"
Bugscope Teamladybugs usually live one reproductive season, so maybe 4-5 months?
Bugscope TeamI think they live around a year. Over the winter, they can hibernate, like in the cracks of people's homes
- Bugscope Teamthere you can see the special tasting hair now that is on the monarch's "foot"
- TeacherMartin wants to know, "Where do beetles live?"
Bugscope Teambeetles are everywhere! they are the biggest section of insects in the world.
- 10:21 am
- TeacherParker is interested to know, "How long did you take classes to become a Bugscope scientist?"
Bugscope Teamwe all have college degrees, so we all went to school for at least 4 years, that's a lot of classes. but it's totally worth it.
- Bugscope Teamjoyce, remember, all this chat and images from this session are saved to your bugscope member page: http://bugscope.beckman.uiuc.edu/members/2008-079
- TeacherSarah is wondering if the bugs with a lot of guts are the nasty ones.
Bugscope Teamwell, yeah, the bigger the bug, the more juicy it can get, and that is kinda nasty, right? :)
- TeacherDevin asks, "What is the biggest bug in the world?"
Bugscope Teamthe goliath beetle is huge! and it can weight 80-100 grams, that's really heavy
- Bugscope Teambut most of these bugs in the scope are dried out because they've been dead for a while
- Bugscope Teamlobsters are related to roly-polys. You can say they are the biggest "bug" if you want :p
- Bugscope Teamhere are some photos of the goliath beetle: http://beetlespace.wz.cz/e_Goliathus_albosignatus_kirkianus.html
- TeacherSean asks, "Do you like Black Swallowtail butterflies?"
Bugscope Teamyes, they are beautiful, here's a nice pic: http://en.wikipedia.org/wiki/Image:Black_Swallowtail_Papilio_polyxenes_1700px.jpg
- Bugscope TeamI think the swallowtails in general are really pretty with the extra flair their wings have
- TeacherMrs. Metger's class wants to compliment all of the scientists at Bugscope.
- TeacherPaige says, " Thank you for helping us learn more about bugs."
- 10:26 am
- TeacherParker says, "We liked that you let us look at all of the bugs on the website."
- Bugscope Teamthank you all for all your questions. we like bugscope. it's fun watching the kids drive the microscope
- TeacherDevin hopes that you learn something new every day.
- TeacherLogan says,
- Bugscope Teamwe do devin
- TeacherLogan says, "Thank you for letting us move the microscope."
- Bugscope Teamyou are all welcome
- Bugscope Teamjoyce, remember the member page, with all the chat and images from this session: http://bugscope.beckman.uiuc.edu/members/2008-079
- TeacherWe give you big HUZZAH (that's what the Founding Fathers would cheer!) for another great Bugscope experience!
- TeacherWe will log off now. Take care!!
- Bugscope Teamthanks joyce, great session today
- Bugscope Teamthanks everyone
- Bugscope Teambye bye, best
- Bugscope Teamokay, closing up the session, nice one everyone
