- Guesthi alex
- Guesthi scott
- Bugscope Teamwhere are you from?
- Gueststate?
- Bugscope Teamyes, are you with today's session?
- Guestno
- Bugscope Teamah, okay, well, welcome as a guest
- GuestI am a guest
- GuestI'm from the state of Florida.
- Bugscope Teamwe have a session at 10AM central with a school in NC
- Bugscope Teamwe'll be setting up presets soon
- GuestNC?
- GuestOKAY
- Bugscope Teamright now you can see the inside of the microscope vacuum chanber, with the stage, and bugs on that stage
- Bugscope TeamNorth Carolina
- Bugscope Teamgood morning you guys
- Guestcool
- Bugscope Team3.5 x 10-4
- GuestHi Scott
- Bugscope TeamAditi I am pumping the chamber down. It needs to go to 1.3 x 10-4 mBar.
- Bugscope TeamAnd I have a juicy spider in there that may be slowing things down a bit.
- Bugscope Team2.3 x 10-4
- Guestpumping the chamber down?
- Bugscope Teamyes the chamber, what we're looking at now, must be under vacuum for the SEM to work
- Guestare we going to get to see the juicy spider that is slowing things down
- 8:37 am
- Guestwhat does SEM stand for?
Bugscope TeamScanning Electron Microscope
- Bugscope Teamwhen we beam electrons at the sample, we get secondary electrons back from the conductive surface of the sample (which we have coated with gold-palladium). The 2ndary electrons are pretty weak and would bump into air molecules if we did not have a good vacuum.
- Guestokay
- Bugscope Teamyeah we are planning to look at the spider; I mounted it so that its eyes are up.
- Bugscope Teamthe vacuum is close, actually, now
- Guestgold-palladium?
- Bugscope Team1.6 x 10-4 mBar
- Bugscope Teamyes an alloy of gold and palladium that covers, very thinly, the whole sample
- Guestwhat for?
- Bugscope Teamwe use a sputter coater to put the coating on, and it is only nanometers, like 6 or 7 nm, thick.
- Bugscope Teamif the sample was not coated it would charge up with electrons, and the images would look terrible
- Guestwhy do you need it?
- GuestI am not sure I would want to see that!
- Bugscope Teamif we were looking at a conductive sample, like a piece of copper or a clean coin, we would not need a conductive coat
- Guestgot it
- Bugscope Teamyeah it makes super dark and super bright areas, and it makes lines run horizontally along the image, looks terrible for sure
- 8:43 am
- Guestwhen will the class be here?
Bugscope Teamclass is coming in an hour or so
- Guestwierd
- Bugscope Teamsometimes we see it with moths, when the images are too bright
- Guestwhy with a moth?
- Bugscope Teammoths have lots of scales, and they are so small they do not coat well, plus there are so many of them they do not carry a charge away from the sample
- Guestsoon I won't be able to come to any bugscope sessions-because of school and all
- Bugscope Teamthat's not a super good explanation
- Guesthi Joanne
- Bugscope Teamok, sec. electron detector is ON!
- Bugscope TeamI mean my explanation is not super good
- Guestelectron detector? what's that
- Bugscope Teamoh this is Scott, still, but I expect Joanne to be in soon, at which time I will use another confuser
- Guestoh hi scott
- Guest"confuser"
Bugscope Teamscott calls computers, confusers
- Bugscope Teamthe secondary electron detector captures the signal from the electrons that are ejected from the sample surface by the primary electron beam
- 8:48 am
- Guestwhy do you call computers confusers scott
- Guestwhat are we looking at
- Bugscope Teamthis is a wing edge i think, scott is working on the presets now
- Guestaditi1 is still me aditi
- Bugscope Team:)
- Guesteye?
- Bugscope Teamyep, comoound eye
- Bugscope Teamcompound
- Guestwhat animals wing?
Bugscope Teama dragon fly
- Guestthought so
- Guestare these pictures of a dragonfly
- 8:54 am
- Guestwhat part is this
- Bugscope Teamthis is some kind of fly
- Guestfruit fly maybe
- Bugscope Teamit's a little big for a fruit fly, we thought at first it was a wasp
- Bugscope Teambut it's got a haltere, so it is some kind of fly
- Guesthow many types of flys are there
Bugscope Teamestimated 240,000 species of fly
- Guestwierd
- Guestthat is way more than
- Guesti could ever imagine
- Guestleg?
- Bugscope Teamleg w/ ovipositor in front of it
- Guestdoes it use those hairs to hold on to things
- 9:00 am
- Guestwhat are those 4 bumps for?
Bugscope Teamthose are eyes
- Bugscope Teamthe hairs are sensory
- Guest4 eyes?
- Bugscope Teameight eyes
- Guestwhere are the others
- Bugscope Teamthey were on top of the head
- Gueststill the fly
- Guestwhat are the hair that are sticking out everywhere
Bugscope Teamthose are setae, sensory hairs, help insects sense their environment
- Guestmy screen went black
- Guestcan't see any pictures
- Bugscope Teamhit F5 (refresh)
- Guesti'll try
- Guestit worked
- 9:05 am
- Guestwhat are these things that are shaped like leaves
Bugscope Teamscales
- Guestwill the class be here soon?
- Guest cool scales
- Guestwhat are we looking at
- Guestthey look like a bunch of brooms
- Bugscope Teamtenent setae
- Guest"tenent setae"
Bugscope Teamtenant means "to hold" so these help the insect hold onto walls
- Guestmakes sense
- Bugscope Teamit's like Spanish 'tener'
- Guestokay
- 9:10 am
- Bugscope Teambut I guess orig from the Latin
- Bugscope Teamor French tenir
- Guestclaw/
- Guestclaw?
- Bugscope Teamtotally
- Guestwhat exactly do they use claws for?
- Bugscope Teamthey use claws for grabbing food, fighting, holding stuff, typical monster type use...
- Guestwhat are all these little dots
Bugscope Teamthose are individual facets of the compound eye, called ommatidia
- Guest"monster type" quite funny
- 9:15 am
- Guestokay
- Bugscope Teamthey kinda look like monsters in an SEM, don't they?
- Guesthow long is this session going to be
Bugscope Teamthey are usually an hour
- GuestThey do sort of look like monsters in the Scanning Electron Microscope
Bugscope Teamright on SEM! good work aditi!
- Guestwhat is that fuzzy-ish thing
- Guestwhat is this pointy thing
- Bugscope TeamDude this is the serious tip of the fascicle, what sticks into your skin
- 9:20 am
- Bugscope Teamshowing two of the lancets, or stylets
- Guest"fascicle"
- Bugscope Teamthey could also be called laciniae
- Guest"stylets"
- Guestwhat are all those words?
- Guestmore scales?
- Bugscope Teamcool, brochosomes
- Bugscope Teamyes more scales
- Guest"brochosomes" what are those
Bugscope Teamthey are very small granules produced only by the leafhopper
- Bugscope TeamAditi you will need to get a leave of absence from school to help us with Bugscope.
- Guestdon't know if I can get a leave of abscence scott
- Bugscope TeamI just read that they were first discovered in 1952 with the aid of an electron microscope!
- Guestif they are only made by the leafhopper what are they doing on a moth
- Bugscope Teamthey may have been collected in the same net or trap
- 9:26 am
- Guestso they can rub off and spread
- Bugscope Teamyep
- Guestthis is the head of a ?????
- Bugscope Teamwhirligig beetle
- Guestif i'm not wrong they can swim-whirligig beetle
- Guestnice claw
- Bugscope Teamgot it Dude they swim
- 9:32 am
- Guestwhat are we looking at?
- Guestwhat is this
- Bugscope Teamthis is a dragonfly
- GuestI wonder when the class will get here
- Bugscope Teamvery soon
- Guesthope so
- 9:38 am
- Guestthere are not many girls like me that are interested in bugs
- Bugscope Team:)
- Bugscope Teamyou are so awesome!! Go Girls!
- Guestat least not in my class
- Bugscope TeamAditi you are a girl, how cool!
- Bugscope TeamSorry I did not know.
- Guestit's okay
- Guestmy name dosn't tell you that because I am Indian
- Bugscope Teamyou have been with us for months now
- Bugscope Teamso I am sorry not to have somehow figured it out
- Bugscope Teamdo you connect from home?
- Guestyes
- Bugscope Teamwhat grade are you in?
- Guesti'll be going into 5th
- Bugscope Teamso this is, like, summer and school's out for you, for now?
- Bugscope Teamawesome! We run a really fun engineering camp here at U of I, you should think about coming one year. You are the perfect age!
- Bugscope Teami should probably know this, but has your class done bugscope before aditi?
- Guestyes school is out
- 9:43 am
- Bugscope Teamnow we are asking you questions!
- Guestmy class has done one before
- Bugscope TeamEnthusiastic girls like you are the kind of future scientists we like to see at our camp?
- Bugscope Teamnot a question...oops
- Bugscope TeamAlex says he is jealous that you have summer off.
- Bugscope Teami wish as a kid i went to school year around, so then as an adult i could have summers off....
- Guestmaybe
- Bugscope TeamJoanne has a cool website/youtube channel you might be interested in.
- Bugscope Teamyou might like my website joannelovesscience.com
- Guestwhat
- Guesti'll check it out
- Bugscope TeamI'm in bioengineering now, but I got my master's degree with an entomologist
- Guestcool
- Bugscope TeamI always loved science!
- 9:49 am
- Guestneat website joanne
- Guestjust checked it out
- Bugscope Teamthank you. I have fun with it! I like to see young people excited about science, especially girls!
- Guestlooks as if we are on a different planet
- Bugscope Teamyeah I am cruising around on the spider head
- Guesthows the weather where you are
- Bugscope Teamyou are free to contact me through the website anytime
- Guestplanet spider head!!!!
- Guestokay joanne
- Bugscope Teamit's always the same; we are in the basement, 23 feet underground
- Bugscope Teamyay!
- Bugscope Teambut outside it has been super nice this summer, not hot, not humid, for the most part
- Guest23 feet
- Guestits hot here in florida
- Bugscope Teamplanet spider head, I like that
- Guestand humid
- Bugscope Teamdo you have anoles and geckos in your yard?
- Guestit is raining right now
- Bugscope Teamspider knee
- Guestnot really but we have plenty of bees and tons of lizards
- Guestspider knee?
- Bugscope Teambees have mites too, sometimes
- 9:55 am
- Guestnot to mention snakes
- Guestmites? what are they
- Bugscope Teamlike this, as it happens
- Bugscope Teammites are not insects; they are arachnids, I think... related to spiders
- Guesthmm
- Bugscope Teamhoneybees have varroa mites on them, and those are much larger
- Bugscope Teamhello HayLiv, welcome to bugscope!
- Bugscope TeamGood morning!
- Bugscope TeamWelcome to Bugscope!
- Guesthello
- TeacherHello - we are logging in for our 11EDT session (Tavi w/ Love of Learning Homeschool in NC) :)
- Bugscope TeamHi Tavi!
- Teachertest
- Bugscope TeamWe are ready!
- Bugscope Teamokay, the session is unlocked, you should now see controls on the right side
- Bugscope TeamYou may now drive if you would like!
- Teacheroh - the scroll is at the top - I was upside down!
- Bugscope Teamthis is the head of a dragonfly.
- Teacherthis is our 1st session - may we play with the controls a little?
- 10:00 am
- Bugscope Teamyep, you have control
- Bugscope Teamof course!
- Bugscope Teamit's all yours
- Bugscope Teamif you have any questions about what you are seeing, feel free to ask
- Bugscope Teamand you are supposed to play with the controls
- Bugscope Teamcurrently, we are looking at a dragonfly
- Bugscope Teamthis is one of the tiny limbs, and now we are looking at the thorax
- TeacherWhat are th e circular objects?
- Bugscope TeamI am not sure -- I think they are some kind of dried fluid
- Teacheron the thorax
- Teacherokay
- Bugscope Teamyou could drive up close and see
- Bugscope Teamthey look kind of like big pollen grains
- Teacherpollen grains perhaps - thank you
- Teacherlooking at the hairs now?
- Bugscope Teamyou may also choose from among the presets to go to a different area of the stub
- GuestSorry I have to go- too much thunder and lightning
- Bugscope Teamthere are lots of critters on the stub for you to check out today
- Teacheroh yes - okay - going for the claw
- Bugscope Teamgood bye aditi
- Guestbye everybody
- Bugscope TeamOh sorry Aditi! See you soon?
- Bugscope TeamBye!
- TeacherI didnt know dragonflies had claws
- Bugscope Teamcool
- Bugscope Teambye aditi...look forward to hearing from you!
- Bugscope Teamyes almost all insects have claws
- Teacherwhere are these located? on the front legs?
- Bugscope Teami'm not sure, you could try zooming out to see
- Bugscope Teamwe can tell that dragonflies are not really equipped to cling to walls or walk on the ceiling
- 10:05 am
- Teacherit lookls as though there is a double claw here
- Bugscope Teambecause there is no pulvillus on the tarsi -- the 'forearm' segments
- Teacherwhat is a pulvillus? is the tarsi the forearm?
- Bugscope Teamyes it is kind of cool-looking, and you can compare it to other claws on the stub
- Bugscope Teama pulvillus is a pad found on some of the tarsi, sometimes, that has tenent setae on it
- Teacherand the pulvillus (the pad) would enable an insect to cling to walls?
- Bugscope Teamit is a pad of sticky setae that help insects/arthropods stick to vertical surfaces
- Teacherthank you
- Bugscope Teamyes because of the tiny setae -- you can see more of them among the presets
- Teacherare we missing three legs? they would be wear those nubs are - on the right side?
- Bugscope Teamyes, it looks like some legs are missing
- Bugscope Teamwhen insects die they can dry out, and become fragile, or more so
- TeacherIt would be interesting to see if that middle arm on the right side (insect's left) has a double claw as well
- Bugscope Teamyou can drive to see it
- TeacherWe are going to zoom in on the mouth with the preset
- Bugscope Teamif you can see where you want to go it is easier to use click to center rather than click to drive
- Bugscope Teamnice job
- Bugscope Teamserious mouthparts
- TeacherHow do the hairs aid in capturing food? Is that their purpose?
- 10:10 am
- TeacherScary looking!
- Bugscope Teamthe hairs are usually sensory, some sort of sensory
- TeacherWow!
- Bugscope Teamsome of the hairs (setae) may be chemosensory, so they could smell food
- Teacherso complex
- Bugscope Teamlike sometimes they are mechanosensory, like cat or rat whiskers
- Bugscope Teamand as Alex said, some are chemosensory
- Bugscope Teamsome are also thermosensory
- TeacherI imagine that insects have highly-advanced sensory perception? How about their eyesight? Do we know much about it?
Bugscope Teamflying insects have excellent eyesight, they have compound eyes which are very complex, with thousands of lens's in them
- Teacheroops - I meant to look at the eyes
- Bugscope Teamif you had compound eyes you would be able to detect motion very quickly
- Teacherhaving a little hangup here - didnt mean to double post
Bugscope Teamno problemo
- Bugscope Teampreset #12 is a close-up of a mosquito compound eye
- Bugscope Teamwe don't see double posts, just as we hope you don't see ours
- Bugscope Teamif your image ever goes black, just hit refresh to reset it (F5)
- Bugscope Teamthese are wing veins, and you can see the little spines
- Bugscope Teamnow one of the skeeters
- Bugscope Teamit has little scars in its surface
- Bugscope Teamgreat job driving
- Bugscope Teamyes, very cool, these are the individual facets of the compound eye, they are called ommatidia
- Teacherthat is one "eyeball"?
Bugscope Teaminsect lens's dont' work like humans do, they can't move around in the socket. but to compensate, insects can have thousands of static pointed lens's and the compound eye is curved, so the field of view is excellent
- Bugscope Teamif you keep going you will be able to see the head
- Bugscope Teamit is part of one compound eye
- Bugscope Teamthe left eye
- Bugscope Teameach ommatidium has a lens in it
- Bugscope Teamcool
- 10:15 am
- Bugscope Teamso cool, I love the scales on the head!
- Teachervery!
- Teacherto the right - those are the scales?
- Bugscope Teamyes those are scales
- Bugscope Teammosquitos, butterflies, moths, silverfish, and a few beetles have scales
- TeacherDo compund eyes detect individual picture w/ each lens? like multiple images?
Bugscope Teamtotally, the bug brain assembles all those images into one... we guess. it's hard to know for sure what a bug really "sees", we can't ask them about it ;)
- Bugscope Teamwhen you brush off a mosquito and not quite squish it, sometimes you see a little black streak on your arm. Those are usually scales left behind
- Bugscope Teamwe found some flattened setae on the spider abdomen that look like smooth scales as well
- Teacherokay - reading your explanation - the compound eye creates a mosaic of one image?
- Bugscope Teamyes we believe it creates frequently updating mosaics in the brain
- TeacherOh cool - the black streaks are scales? I never thought of mosquitoes as having scales
- Teacher(explaining compound eye to children - one sec)
- Bugscope Teamif you look at a fruit fly brain, as many people do, you see that much of the brain is devoted to visual processing
- Bugscope Teamlike a huge majority of the brain is dedicated to processing images
- Teacherlooking at moth claw now
- Bugscope Teamanother claw here
- Bugscope Teamanother claw, on a moth, yes!
- Bugscope Teamand this one can hold onto walls, too
- Teacherdaughter says that insect claws resemble birds claws
Bugscope Teamyes! totally. it's very interesting what some of these small structures look like under a microscope. some things are "discovered" under a microscope, brochosomes for example, preset #16
- 10:20 am
- Bugscope Teaminside the tarsus is a sort of tendon called an unguitractor that pulls the claw open and closed
- Bugscope Teamthey do, don't they?
- Bugscope Teamthey are very tiny
- Teacherwhat are the elongated structures on the leg?
- Teacherscales?
- Bugscope Teamyep, those are scales
- Bugscope TeamMoths and other insects with scales can leave some behind if caught in a spider's web
- Teacherthe dust on a moths' wings - that isnt scales, is it?
- Bugscope Teambrochosomes are those small balls. try to zoom in on one, they are very cool looking
- Bugscope Teamnot dust, but brochosomes! very cool things produced only by the leafhopper
- Bugscope Teamyou may need to focus, if you want help let us know
- Bugscope Teamto us the scales seem like powder or dust
- Bugscope Teamthe dust is indeed the scales!
- Bugscope Teamscott is focusing a bit
- Bugscope Teamso if you catch a moth and have dust on your hands, they have given you their scales
- Bugscope Team42,000 x magnification, very sweet
- Bugscope Teamthe brochs are about 300 nm in diameter
- Bugscope Teamthey may protect eggs, keep them from drying out
- Bugscope Teamsee how the brochosomes look like soccer balls, they are thought to help moisten the leafhopper eggs, or keep them moist
- TeacherTU for the focus - this computer is lagging a bit
- 10:25 am
- Bugscope Teamthey are said to be produced only by leafhoppers
- Bugscope Teambrochosomes were totally unknown to humans until 1952 when someone looked at a leafhopper under and electron microscope and found some
- Teacherthose spots are actually holes in the brochosomes? like a sponge?
Bugscope Teamyeah, depressions in the surface of the brochosome. i'm not sure why it has those holes... interesting question!
- Bugscope Teamthe images we're getting would be better if we were closer to the sample
- Bugscope Teamyes they are pores or holes
- Teacherare the indents where other brochosomes once were?
- Bugscope Teamsome brochosomes are oval
- Bugscope Teamno those are indents on the scales but have nothing to do with the brochs
- Teacherfascinating
- Bugscope Team:)
- Teacherwe see insects as so simple, but they are highly evolved specifically for their environment
Bugscope Teamtotally
- Bugscope Teamthe shape and geometry of scales can produce structural colors
- Bugscope Teamscales are some of the most fascinating structures to view using this type of microscope
- Teacherlooking thru spider slides - going to look at a claw
- Bugscope Teamone thing kids notice about looking at insects close up is how hairy they are. lots of setae on insects, all over. those setae are critical, they help them sense their environment
- 10:31 am
- Teachersetae are like cats whiskers?
Bugscope Teamyep, totally
- Bugscope Teambecause insects have a hard exoskeleton and can't feel with it, they need those setae (which stick through the exo to nerves underneath) to feel things
- Bugscope Teamsome setae are like cat or rat whiskers
- Bugscope Teamthey are like cat whiskers if your cat was in a suit of armour
- Bugscope Teamthat is, some setae are mechanosensory
- Teacherwhat is the substance that gives some scales their iridescent color
- Bugscope Teamwhat makes them iridescent is the shape
- Teacherneat!
- Bugscope Teamthe ridges, and their spacing, make colors
- Teachernow are we looking at bottom of the claw?
- Bugscope Teamthat's why they are called structural colors
- Bugscope Teamthis is the end of one of the spider's limbs
- Teacherthe bottom of his foot looks like carpet
- Bugscope Teamit also has tiny setae on it, and they have super tiny setae on them
- Bugscope Teamlight bounces off of the different structural patterns and looks like colors to our eyes!
- Teacherwhy dont spiders stick to their own webs?
- Bugscope Teamyes if you were to look up close you would see that it is more like a gecko foot
- Teacherand can spiders be caught in other webs?
- Bugscope Teamsome web is not sticky
- Bugscope Teamand they can eat the web, as they usually do anyway, if they get stuck
- Bugscope Teamsome of the silk they produce is not sticky
- Teacherand the spider knows which parts are or are not sticky?
- Bugscope Teamalso, if you have scales, you can leave the scales and slip out of a web in some cases
- Teacherwe wzoomed in with camera on a spider web the other day - one strand is actually many strrands
- Teacherooh yes - like a lizard loses part of his tale to escape
- Bugscope Teamspiders have lots of setae that probably help keep them from getting trapped
- 10:36 am
- Teacher*tail
- Bugscope Teamgeckos do that
- Bugscope Team:)
- Bugscope Teamthis is do cool
- Bugscope Teamso cool
- Bugscope Teamthis is such a great image!
- Bugscope Teamthis is a dust mite
- Teacherthis is an awesome image
- Bugscope Teamyou can tell from the scalebar that this is super small
- Bugscope Teamso very lovely
- Teacherzooming in on the "fingerprint" ridges
- Bugscope Teamusually they collapse without proper preparation, but this one looks good!
- Bugscope Teamyes this was a great surprise for us
- Bugscope Teamthey are similar to ticks in that they have lots of room for expansion
- Teacherwhat is that little ball at top center of frame?
- Bugscope Teamlooks like pollen or a mold spore
- Bugscope Teamit is awfully small
- TeacherIm having slow response time with this computer - will have to try laptop next time
- Bugscope Teamit is best to use Safari
- Bugscope Teamwe have trouble with lag as well, sometimes
- 10:41 am
- Bugscope TeamI did that, scince I am sitting at the 'scope
- Bugscope Teamit looks like a mold spore to me
- TeacherWe're wondering about all those ridges
- Bugscope Teamnow we see charging
- Bugscope Teamlike an accordian, this bug can expand
- Bugscope Teamif it consumes enough stuff
- Bugscope Teamhey scott what do they eat?
- Bugscope Teamthe ridges ensure that if the mite gets a good meal it can, as Joanne said, expand
- Bugscope Teamany idea?
- Teacherah! the ridges allow for expansion?
- Teacherok - tu
- Teachericky!
- Teacher:)
- Teacherack!
- Bugscope Teamthere's a song about mites-- they eat flakes of skin like taco chips
- Teacherspider head!
- Bugscope TeamI guess something's gotta clean up after us!
- Bugscope Teamhello!
- Bugscope Teamyou can count the eyes
- Bugscope Teamharder to see the four on top
- Teacheroh no - I was finally getting over fear of spiders - this just set me back ;)
- TeacherIs each spider eye a compound eye?
- Bugscope Teamchelicerae in front, but we cannot see the poison pores and barely see the fangs if we drive down there
- Bugscope TeamIt is a new perspective, that's for sure!
- Bugscope Teamthey are, according to me, simple eyes
- Bugscope Teampretty sure they are not compound
- Teachertrying to drive down to fangs -
- Bugscope Teamoften spiers do not see so well
- Bugscope Teamspiders, that is
- Teachercant get the little drive symbol to come up - computer thinking about it
- 10:46 am
- Bugscope Teamsorry, sometimes we log out and back in to clear
- Bugscope Teambut I moved us to the fang
- Bugscope Teamit is hard to see with the hair and palps
- Teachertu
- Bugscope Teamthis is a female, I think, because it has narrow palps
- Bugscope Teammale palps are often fatter, more bulbous
- Teacherwhat are palps?
- TeacherIm going to log out and back in - brb
- Bugscope Teambecause female spiders are often larger, and often quite hungry, they may eat the males
- Bugscope Teampalps are the extendable mouthparts --accessory mouth parts
- Bugscope Teamso males sometimes make a wad of web and paste it onto the front of the chelicerae so the female cannot bite
- Studentgood idea!
- Student:)
- Bugscope Teamafter I had read about that I found a female with a wad of web there
- StudentI have a better response time now but the controls are gone - we dont mind if you drive :)
- Bugscope Teamsorry I just fixed that for you'
- Bugscope Teamforgot
- StudentI think we are logged in twice
- Bugscope Teamyeah no problem
- StudentOkay - we now have the driver controls but no presets
- Studentthere they are - thank you
- Studentzooming out on the spiders head
- 10:52 am
- Studentfly spiracle - what is a spiracle?
- Bugscope Teamit is the hole that insects breathe through
- Bugscope Teamthere are several along the sides of the abdomen on every insect
- Studentoh wow - we still dont have the image up to zoom in and out - thats okay - session is almost over
- Studentbut where is that hole (spriacle) located on the insect?
- Bugscope Teamzoom out to see
- Bugscope Teamthey are often on the sides of the segments
- Studentoh - there it is!
- StudentGreat shot!
- Bugscope Teamtwo per segment, on either side
- Bugscope Teambrb
- Bugscope Teamvery neat!
- Studenton how many segments?
- Bugscope Teamdepending on how we mount the insects in the microscope, sometimes we can't see them
- Studentson is telling me that the more oxygent there is in the air, the larger the insects will grow
- Studentlook at those other teeny holes - three in a diaginal line - see them?
- Bugscope TeamI've heard that, too! They are limited in size by the weight of their exoskeletons
- Bugscope Teamso they can only grow to a certain size
- 10:57 am
- Bugscope Teambefore it takes too much energy to move around
- Bugscope TeamI think those are bases of broken-off spines
- Studentare yeh - makes sense - the spines
- StudentOkay - we have enjoyed this immensely and have learned much
- Bugscope Teamyes when the dinosaurs were around and there were lots of plants there was also a higher level of O2 in the air
- Bugscope TeamCool!
- StudentWe are looking forward to another session. This time we will catch the critter and send to you
- Bugscope TeamThis stuff is all stored on your member page.
- Bugscope Teamhttp://bugscope.beckman.illinois.edu/members/2009-085/
- StudentYes, Son is telling me that insects of past were much larger due to that higher oxygen level- 8ft long centipedes - wow!
- StudentOkay - thank you very much! See you later :)
- Bugscope TeamAlex had to go but I used his computer to do that...
- Studentlol
- Studentbye bye
- Bugscope Teamcentipedes are not insects, though... ;)
- Bugscope Teambye!
- Bugscope Teambye!
- StudentOh - not insects? another chapter for us :) bye bye
