- 12:28 pm
- Bugscope Teamokay microscope is still pumping down
- Bugscope Teamthis is a CCD view of the chamber while we wait for the vacuum to get a little better
- Bugscope Team(this is Scott)
- Bugscope Teamheh nice login
- Bugscope Teamname
- Bugscope Teamvacuum is almost there
- Bugscope TeamHello Beaver
- GuestGreetings from Canada. We're excited to see a session unfold live
- GuestWhich arthropods are those?
- Bugscope Teamum I am not sure -- Cate made the sample
- Bugscope Teamshe's back and forth, not right here right now
- Bugscope TeamI have a meeting right when the session starts at 1:30 our time
- 12:34 pm
- Bugscope Teamcentipede june bug ladybug fly wasp dragonfly head moth roly poly earwig
- Bugscope Teamweevil and spider
- Guestquite a selection
- Bugscope Teamvacuum just landed
- Bugscope Teamfirst Cate will make some adjustments to the 'scope
- Bugscope Teamthen she'll start making presets
- Bugscope Teamduring this time we keep people locked out; we don't allow them to control the 'scope
- Bugscope Teamthat would just be the first person who logged in as a teacher; that person automatically gets control
- Bugscope TeamI just gave Beaver control, but he is locked out
- 12:39 pm
- GuestI think I am just a guest
- Guestthis is very cool stuff
- Bugscope Teamyeah you are just a guest but we conferred control to you; still you are locked out
- Bugscope Teamright now Cate is cruising through the sample, using a map she made to help find all of the critters; then she pinpoints something we will make into a preset for the session
- Bugscope Teamwhen our participant gets control, she/he can click on presets to get around, but it is also possible to drive the 'scope outright
- Bugscope Teamyou can see a lot of charging on the weevil antenna, so Cate i driving elsewhere
- Bugscope Team*is*
- 12:45 pm
- Bugscope TeamCentipede with brachydactylism
- 12:51 pm
- Bugscope Teamyou can see that the presets are starting to add up
- Guestwould the person in control simply click on a preset?
- 12:56 pm
- Bugscope Teamyes. but the person in control can also change the mag, click to center to move around, focus, adjust contrast/brightness
- Bugscope Teamkind of a nasty fly, no sponging mouthparts
- Bugscope TeamI am sitting at the server computer, next to the 'scope, and Cate is sitting at the 'scope
- Bugscope Teamso I am typing the presets in as Cate finds them
- Bugscope Teamecdysis
- 1:01 pm
- Bugscope Teamthese guys are related to ants
- Bugscope Teamstinger is missing
- Bugscope TeamCate is looking for the hamuli
- Bugscope Teambut stopped at the spiracle for a sec
- 1:07 pm
- Bugscope Teamno hamuli visible
- Bugscope TeamMr McG!
- Bugscope TeamWelcome to Bugscope!
- TeacherHi guys...We'll have a crew of kids in about 10 minutes! Thanks!
- 1:12 pm
- Bugscope TeamCate is making the presets.
- Bugscope TeamI have (this is Scott) a meeting right when the session starts, so Cate will be your sole guide today.
- TeacherNo problem...I'll be back in a minute...need step into the hall as kids come back from lunch.
- 1:18 pm
- Bugscope Teamalright, Cate is done. I am heading to my meeting.
- Bugscope TeamCate will on in a sec
- Bugscope Teamthe session is unlocked and ready to roll when you are
- 1:26 pm
- TeacherOK back....students will start logging in soon
- Bugscope Teamok great
- Bugscope Teamhey everyone!
- StudentThis bug is huge!
Bugscope Teamactually this is a very small insect for today. It just looks big.
- Studentyeah it is
- Studentits creepy
- Studentwhat is it
Bugscope TeamWe aren't sure what type of bug this is. Looks like some type of beetle
- Studentwho's chaos
Bugscope TeamThat's just the computer's name that is in the room with the microscope
- Studentoh of course :). It's just enlarged!
- Studentscott who??
- Student@linda wait what?
- StudentWhat are you talking about Linda?
- Studentwhts up
- Studentwhat kind of bug is it
- Student/linda hi
- Studentso does chris
- Studentwht are we sapose to do
- Studenthe looks confused
- Studentcan we see differend insects
- Studenthello are u there
- Studenti think so
- Studentim here
- 1:31 pm
- Studentthis is cool
- Studentthat is 1 huge bug man!!!!
- Studentwe know that
- Studentnext picture mss
- Bugscope TeamSo mr. mcgeehan can either drive around himself or he can ask us to confer control to one of you and you can drive to the different insects
- Studentwho is chaos
- Studenti see you chad
- Studentlinda its small
- Studentis that bug doing something
- Bugscope Teamto the right is the abdomen and pincers of an earwig- one of those pincer bugs
- Bugscope Teamso this insect is smaller than the pincers
- Studentchaos is a awsome name
- Studenta bug
- Bugscope TeamThe background is carbon tape (the bubbly stuff) and it's used to stick the insects to
- Bugscope Teamwe stick most insects on their backs/dorsal side because the ventral side is the more interesting part to look at
- Bugscope Teamthe top of the head is to the upper right and the roundish hairy thing is one of the antennae
- Studentwhat is the fuzzy apendage
Bugscope Teamthat is the antenna. And you can see they are very hairy. Hairs on insects are called setae (see-tee). They have different functions like touch, smell/taste
- Bugscope TeamThe bumpy part is the compound eye. You can see it looks like a beehive
- 1:36 pm
- Studentwhy does it have so many bubbles on it's eyes kate?
Bugscope TeamThey are each connected to a series of nerves and are thought to each get a bit of the picture of what it sees. The bits are collected and assembled in the brain
- Bugscope TeamThe hexagons are the best shape to fit the most in a rounded object.
- Studentwhy is there hairs on the eyeballs?
Bugscope Teamthose short stiff hairs are helpful for feeling
- Bugscope TeamThe more bumps, or as they are called ommatidia, the better they are thought to see
- Bugscope TeamFlies, moths, butterflies- those flying insects, have a lot of ommatidia
- StudentCan these beetles see the way we can? For example, do they see colors and but do they also see things in double?
Bugscope TeamSome insects like bees only see certain colors. I'm not sure what that beetle can see
- Bugscope Teamthis is a small moth
- Bugscope Teamyou can see the eyes take up most of the head
- 1:42 pm
- Bugscope TeamThose things it's covered in are scales
- Studentare the insects still alive
Bugscope TeamNo They are all dead. These samples are sitting in a vacuum, so the insects would quickly die and probably ooze out their insides if they were alive
- Bugscope TeamScales do have a defensive purpose- they can shed some to help get out of a spider web
- StudentHow is this micro scope different from the rest ?
Bugscope TeamThis microscope is acting in regular high vacuum mode, but we can change it to work in environmental mode as well, where we can put the chamber to 100% relative humidity and look at wet samples.
- Studenthow much did the electron micro scope cost
Bugscope Teamthis cost about $600,000 around 11 years ago. I'm not sure how much it would cost nowadays
- Bugscope Teamright now all these insects are dried, which makes them great for bugscope because they retain their shape after drying
- Bugscope TeamThis is a fly claw, and the little pads around it are called pullvilli, each pullvillus has tennent setae which help the fly walk on vertical surfaces
- Bugscope Teamlike velcro or suction cups
- 1:47 pm
- Bugscope Teamthe end of each leg has a claw, but sometimes the insects get a little brittle as they dry out so some claws or legs may be missing
- Bugscope Teamthere is also a bit of lint on this insect
- Studentwhat are the setea used for on the rest of the body?
Bugscope TeamMost of the hair on the body is for touch. It can't feel things through its exoskeleton like we can through our skin. The hairs are connected to nerves beneath the exoskeleton
- Bugscope TeamI believe this is a horsefly because it has biting mouthparts
- Bugscope TeamInsects are a lot hairier than they may seem
- Bugscope TeamThis is a spiracle, which is a breathing hole for insects. They dont have noses like we do
- Student.is this a spiracle
- Bugscope TeamThese holes are connected to a long tube that runs throughout the body, called a trachea
- 1:52 pm
- Studentwhat is that
Bugscope TeamThis is the wasp head. The mouth has a pair of jaws that have 3 prongs on them. They open like a gate, not like ours
- Bugscope TeamYou are doing a great job driving around Mr. McGeehan!
- Bugscope TeamThough I know you've done this a few times already
- TeacherThanks! kids are lovin' it
- Bugscope TeamThe thing curving around the head is the antenna
- Studentwhy do the insect cross the hands when they die
Bugscope TeamThat's a good question, I think part of it is due to it drying up, and it kind of just shrivels that way
- Bugscope TeamThese are mites on an earwig. They are parasites that we don't know too much about. We think they have a symbiotic relationship and for some reason they die with the host
- Bugscope Teamyou can see little round bumps all over
- Studentcan the mites live in anything else than an earwig
Bugscope TeamYes but they are found more often on earwigs. I'm not sure the reason for that. Maybe the earwig can't clean them off so easily as other bugs
- 1:57 pm
- Studentwhat is the line on the eye
Bugscope TeamIt's something that doesn't belong to the insect. Some type of juju- stuff that we don't always know what it is, but know that it doesn't belong there
- Bugscope TeamIt could be plant particles or dirt
- Studentthank you
- Bugscope TeamFlies have huge eyes making it so they can see almost 360 degrees around it
- Studentoke doke
- Bugscope TeamElectrons are smaller than photons, making it so we can zoom in even more than a regular ligh microscope
- Bugscope TeamWe can resolve things as small as 2 nanometers
- Studentwhy do they have so many segments on there leg
Bugscope Teamit allows the insect to bend their legs. It's not easy to bend their leg if it's just one piece of exoskeleton. It's like us trying to bend our bones
- 2:03 pm
Bugscope TeamThey have little muscle attachments underneath that they can flex
- Bugscope TeamYou are all asking such great questions!
- Studentafter the insects die is there any thing else you do to them
Bugscope TeamNope. For bugscope I stick them on the carbon tape that is affixed to an aluminum disk. Then we coat them in a very thin layer of gold/palladium alloy and stick them in the microscope
- Studentthank u
- Studentwhats your backround in training Cate?
Bugscope TeamI got my bachelor degree in Physics believe it or not. I started working with bugscope in 2005 and since then have been learning about insects. I know about as much as some entomologists probably
- Studentare the claws sharp
Bugscope TeamThey are mainly used for grabbing onto things. You might have felt a ladybug cling to you once it landed on you. You don't really feel them. They can seem sharp to other insects though I bet
- StudentThanks Cate
- Studentwhat is that
Bugscope TeamWe are on the spider. They have special hairs for feeling vibrations
- Studentthank you
- Studentwhere did u get your bachelor degree
Bugscope TeamHere at the University of Illinois
- Studentthanx cate this was cool
- Studentbye bye cate!!! thank u!!!!
- StudentHOLHI IM SORRY FOR WHAT I DI
- Bugscope TeamSpiders have simple eyes
- Studentthank you
- Studentur awesome
- Studentthank u
- Studentthank you that was fun.
- Studentthanks and bye! from Jackie. this was interesting and cool
- Studentthank u that micro scope is awesome have a good day bye :)
- StudentTAHNK YOU
- Studentthank u
- Studentthank u
- Studentbye that was cool
- Studentthanks u are e the best ever
- 2:08 pm
- Studentthank u
- Studentgoodbye cate you where awsomer than bugs and i think that b ugs are even more gross. haha thank you. goodbye
- Bugscope TeamThanks and have a great weekend!
- Studentthank u!!ur awesome!!!
- Studentthanks from casssie you are awsome -.-
- Bugscope Teamawesome, well I still think some bugs are gross
- TeacherCate....great job..I'll be back in about 10 with one more crew of kids!
Bugscope TeamOk can't wait!
- 2:16 pm
- TeacherHere they come!
- Bugscope TeamOk I'm here ready!
- Bugscope TeamHi!
- Bugscope Teamwe are looking at a spider that is standing up look up at us
- StudentWhen did you become interested in Arthropods?
Bugscope TeamI never set out to learn all about them. It kind of found me. I started working in the lab and then one day in 2005 someone asked me to log in and help (even though I didn't know anything) and since then I've been learning all about insects and other related things
- StudentWAT IS TAT
Bugscope Teamwe were looking at a spider, now we are looking at individual scales on a small moth
- Bugscope TeamThis is the same as the powder that comes off the wings, they are that small
- 2:22 pm
- Bugscope TeamThose small holes you see are nanometers big
- Bugscope TeamScales can be shed without hurting the moth
- Bugscope TeamThe moth can lose some to shake out of a spider web sometimes, which is pretty cool
- Bugscope TeamThe background behind the wing is carbon tape.
- Bugscope TeamHere's the moth head
- Studenthow is a electron microscope different than a normal microscope?
Bugscope TeamA scanning electron microscope uses electrons to image instead of photons like a light microscope. That's why it's in black and white. Another thing is this electron microscope is special because it can also be in a different mode than we are in now and be used to image wet things.
- StudentAre the insects alive right now?
Bugscope TeamWe are looking at dead insects. None are alive. They have to be dead and dry to be used in the microscope while it is in high vacuum mode
- StudentAre you going to School? If so which one?
Bugscope TeamI am in a lab with the microscope that is on campus at the University of illinois
- 2:27 pm
- Bugscope TeamIf an insect were alive and put into the microscope, as the microscope pumps to vacuum the insect would suffocate and it's insides would probably ooze out, which is pretty gross
- Studenthow big is the microscope
Bugscope Teamthe microscope sits by itself in it's own room and has two parts. The main part is as big as a fridge and the other part, which is the computer part, is as big as a large desk
- Studentis that a dust mite
Bugscope TeamHere is a mite sitting on an earwig. They are found most often on earwigs, I think because the earwig can't brush them off as easy. Dust mites are soft bodied and dont look as nice
- Bugscope TeamAll very good questions so far :)
- Bugscope Teamif you didn't know, earwigs are those pincer bugs you find under rocks
- 2:32 pm
- StudentHow big is a Mite?
Bugscope TeamIt's big enough to see under a light microscope, but definitely smaller than a millimeter
- Studenthow much can the microscope zoom
Bugscope Teamwe can resolve things as small as 2 nanometers
- Bugscope TeamAll that stuff there you see is dust or bug parts. This was in a box where there were some maggots and they were eating other insects so these are probably little bits
- Student why do dust mites live on other animals
Bugscope Teamdust mites like to eat dander and human skin flakes
- Studentis it sperical
- Student do mites live on humans???
Bugscope Teamthere are mites on our eyelashes and our foreheads
- Bugscope Teamthere was something here but it was blown away it looks like
- Bugscope Teamsometimes things can fall off
- 2:37 pm
- Studentcan the mites harm us?
Bugscope Teamwe dont think they do. We think there's a symbiotic relationship where they dont harm us or necessarily help us even
- Student WHAT ARE THOSE?
Bugscope Teamthe round bumpy thing is a compound eye with lots of little facets in them
- Bugscope Teamthe hole you see is where a palp broke off
- Bugscope Teamthe palp is something that can move or taste food
- Bugscope Teamthis hole here is a spherical, which is similar to our noses
- Bugscope Teamit's connected to a long tube, or trachea, that runs throughout the entire body
- Studentwhat are the function of the hairs?:)
Bugscope Teamthe hairs are connected to nerves underneath the exoskeleton, allowing the insect to feel things like we can with our skin
- Studentdo you know why bugs dont have noses
- Bugscope Teamthere are other functions for some hairs like here
- Studentif u zoom in enough on a beetal could u see vains on there hard wings
Bugscope Teamwe can't see through things but the wings actually have external ridges for the veins like a leaf
- Bugscope Teamthese hairs, or tennent setae, allow insects to walk on walls
- 2:42 pm
- StudentDo you know why bugs don't have noses?
Bugscope Teamthey dont really need noses, they have antennae and palps that are used to "sniff" and spiracles (not sphericals sorry I just realized my mistake) to breathe
- Bugscope Teamhere are bitemarks
- Studentwere you ever interrested in arthropods before you got this job?
Bugscope Teamnot really, i really didn't don't like live insects. I guess that's why I'm great with bugscope because they're dead
- Studentwhat are the bite marks from
Bugscope TeamThese insects were in a box that hatched some maggots and they got hungry
- 2:47 pm
- Studentwhere do you get the bugs from
Bugscope Teamsome schools send them in, we sometimes get insects from people who work here
- Bugscope Teamhere's a house centipede
- Bugscope Teamthey are creepy
- Studentcan the pinchers hurt you
Bugscope TeamThey do a little. It pinches, but there's no venom
- Bugscope TeamHere's a weevil. They like seeds
- Studentare these feet or antennies
Bugscope Teamthese are legs
- TeacherOooh, that's an evil weevil!
- 2:53 pm
- StudentWhere do most weevils live?
- Bugscope TeamThey live in food like flour or cereal or in trees or the ground
- Studentdo they have compound eyes or what because it looks like they hav more
Bugscope TeamSpiders have simple eyes.
- Bugscope Teamthey don't see as well with simple eyes, usually light changes or movement
- StudentWhat are simple eyes and how many do they have?
Bugscope TeamSpiders have eight (like the number of legs) and it just means they don't have little facets (like all those bumps you saw on the fly)
- Studenthow bid is the lenseon the microspoe
Bugscope TeamThe microscope doesn't have lenses they have magnets to manipulate the electron beam. I've never seen them. They are in the column as big as a fridge
- StudentHas there ever been a weevil packaged in a cereal box or in a package of flour?
Bugscope TeamIt can happen I think. But it probably happens after packaging. I'm not entirely sure
- Studenthow much does the microscope cost?
Bugscope TeamIt cost around $600,000 11 years ago
- 2:58 pm
- Studenthow much dose it weigh
- Studentgoodie jobie!
- Studentthank you for sharing your knoledge with us!
- Student I think you are my rule moder bye :)
- Studentthank you i am impresssed by your superior skill in microsscopic scientific science good job! bye
- Studentgood by homs
- Studentthank you your are awesomeo
- StudentThank you Good bye
- StudentSee u later
- Studentthankyou for everything!!! you are the best bye!!
- Studentamazing amazing goodbye
- Studentthank you for talking with us you rock for that bi bi from savannah and taylor we rock too
