- Bugscope Teamhi michelle, welcome to bugscope
- Bugscope Teamwe are just starting to setup for a 10
- Bugscope Team10:45AM (central) session
- GuestThanks! I'm a doctoral student in education at OSU and heard about your program. Just thought I'd check it out.
- Bugscope Teamcool
- GuestWhat sort of bugs are those?
- Bugscope Teamyou are welcome to watch the entire session, and before or after the class is done, we can let you control the scope as well
- GuestThanks!
- Bugscope Teamright now, it's just a CCD image of the inside of the electron microscope, soon we'll turn on the electron sensor
- GuestHow many schools do this each year. Any idea?
- Bugscope Teamwe keep all that detail on our website: http://bugscope.beckman.illinois.edu/
- Bugscope Teamwe do about 2-3 sessions a week, so that's 2-3 times however many weeks we've had so far this year? i'm not sure
- Bugscope Teamwe only do 2-3 sessions a week because we all also have full time jobs in the labs here
- GuestWow! 2 to 3 a week is a lot of work!
- Bugscope Teamyeah, but we've got a lot of the technical aspects automated, it's really just the time of the session, which is an hour, so maybe 3-5 hours a week on it. not too much. :)
- 9:53 am
- GuestReally great of you folks to take the time. I'm sure the kids really dig it! I'm just going to hang in the background and see how the session unfolds.
Bugscope Teamok, we are still about 50 minutes away from the session start. feel free to come and go as you need to. and if you have a question, just ask us
- Bugscope Teamyou should sign up for a session if you want. we also do sessions for teachers who are considering using bugscope in their classrooms, if you've got a group of interested teachers, go ahead and apply: http://bugscope.beckman.illinois.edu/participation
- GuestI'm trying to get a group together to do that. I'm doing some reading while I wait.
- 10:09 am
- Bugscope Teamvacuum is taking its own sweet time... almost there
- Bugscope Teamremoving a juicy bug now. trying the vac again in a few moments...
- 10:15 am
- GuestSorry guys - I've got to run. I was just reminded of a meeting I have in 15 minutes. Darn it. I'll get the teachers together and try again another day! Thanks so much!
- Bugscope Teamno problem, hope to see you another time
- 10:27 am
- Bugscope Teamhi Ms. Gardner, welcome to bugscope, we are setting up presets for you
- Teachergreat- thanks- just setting up computers.
- 10:34 am
- TeacherDid you see email that I sent this am about what bugs we have looked at w/our school computer microscopes?
- Bugscope Teamwe did get that, but not in time for today's sample. however, for friday, we will do our best
- Bugscope Teamwe have been having trouble with the vacuum in the scope this morning, we will be a little behind
- 10:40 am
- Teacherok- thanks! that works out great too - will have different sessions to share. I have my teacher computer and seven student computers for this session. Student computers are ready for student sign-in. will diff students sign in and out or assign computers #1student , #1 student
- Teachertake your time. I have 2 classes on the way- that will take time too.
- Bugscope Teamyep, students can login as any name they choose, and we can give control of the scope to any student upon your command
- 10:46 am
- TeacherStudents re here and watching- let us know when you are ready.
- 10:51 am
- Bugscope Teamwe are almost ready, just another couple of presets
- Teacherok-
- Bugscope Teama couple more presets of different insects
- Bugscope TeamMsGardner we thought we had a too-juicy assassin bug, or spider, but then it turned out there was juju on the stage door as well -- so the 'scope took its time pumping down. It's good we have Cate whipping through the presets.
- Bugscope Teamwe are ready, presets are done
- Bugscope Teamthis is the head of a fly
- Bugscope Teami just unlocked the controls, so you should see magnify, mav, focus and adjust
- Bugscope Teamwe can also give control to any other student that is logged in as well
- Teacherwe are ready too time for students to sign in?
- Bugscope Teamyou can see its tongue, in the middle, and its eyes
- Bugscope Teamyep, go ahead and log in please
- Bugscope TeamOh yes.
- Bugscope Teamhi students, welcome to bugscope!
- Bugscope TeamHello! Welcome to Bugscope!
- StudentHi
- Studentwhat am i lokking at?
Bugscope Teamthis is the head of a housefly
- Bugscope Teamthis is a housefly, and you can see the antennae, the compound eyes, the tongue
- StudentHello
- StudentHi
- Bugscope Teama female
- StudentHello!!
- Bugscope Teamwelcome
- Bugscope Teamyou can see one of its forelimbs as well, at the bottom of the screen
- Bugscope Teamthese are all live images from an electron microscope
- StudentHow do you know its a female
Bugscope Teamflies are usually female when its eyes are spaced really far apart, males have eyes closer together usually
- Bugscope Teamthe middle of the head is the tongue, the two orbs on the side are the compound eyes, and the parts on top of the heads that are sticking out are antennae
- Bugscope Teamand ms. gardner is controlling the scope now
- Studentwow
- 10:56 am
- Bugscope Teamright into the mouth
- Studenthow do you know its a female
- Studentcool
- StudentWhat else can you tell us?
Bugscope TeamWhat would you like to know? We have a whole cast of characters here. I am an entomologist, Scot and Cate are microscopists, and Alex is our awesome Systems Administrator
- Studentis it alive
Bugscope TeamNope, it is quite dead. We couldn't want it crawling around inside the microscope
- StudentWhat do the eat?
- Bugscope Teamhere are the antennae
- Bugscope Teamall those hairs are called setae (see-tee), they help the insects sense their environment, all insects have setae
- Studenthis eyes are big
- Studentwhat is that thing in the middle?
- Bugscope Teamthey have two parts to them- a furry pad and a branch, I'm not sure of the technical names to them though
- StudentWhere is his eyes?
- StudentWhat do they eat
Bugscope TeamHouseflies eat almost anything that is sort of rotten and squishy...rotten fruit, sticky ice cream, mayonaise, animal dung
- Studentoh
- Studentwhat is a branch
Bugscope Teamit is the part connected to the furry pad part of the antennae
- Bugscope Teamto the left is the compound eye, made of TONS of facets called ommatidia
- Bugscope Teamnotice the scale bar in the lower left of the image, that tells you size. 1 um is one micron = one millionth of a meter
- Studentthey look a lot diffrent up close
- Studentthis is so cool!!!!!!!!!!!
- Studentthats really hairy!
Bugscope Teaminsects are a LOT hairier than they seem, which will probably make you think they are more gross than before
- StudentNeat!
- Bugscope Teamsome setae (hairs) are chemosensory and some are mechanosensory
- Bugscope Teamtotally, insects are very hairy
- StudentDo you ever put live bugs under this?
Bugscope Teamnot on purpose
Bugscope Teamwe try not to, because live bugs usually move around, and we need them to be still for good imaging
- StudentWhy does it look white
Bugscope Teamthe colors are black and white because we are NOT using light (frequency of light) to get the image. the scope is shooting and gathering electrons inside the scope chamber, and those electrons made up the image
- Studentdo you think mrs.gardener is awesome,I do
Bugscope TeamMrs. Gardner is awesome because she is running Bugscope with you all ;)
- StudentNo
- Studentwhat other insects do you put under it?
- Studentthats a hairy bug
- Studentwhen a mosquito lands on me it doesnt feal hairy
Bugscope TeamThe hairs are usually too small for humans to sense
- StudentWhat bugs do you like looking at?
- Bugscope Teamplus live bugs are really juicy, and that makes it hard for the vacuum to pump to where it needs to be. That is one of the reasons we were a little behind today-- we had a couple freshly dead insects
- Studentdo you ever put live bugs under the michrosoft
Bugscope Teamnope, won't get good images if your bugs are moving around
- 11:01 am
- Studentis it true that flies see in lots of little octagons
Bugscope Teamwe think that they see lots of images and have to assemble them into a coherent whole in order to comprehend what they are seeing
- Studentwhat is that
- Studentwhat other insects do you put under this??
Bugscope Teamall kinds, as long as they fit into the stub (1.5 inches biggest), other non-living things too
- Studenti think beetles are cool
Bugscope Teambeetles can be even cooler than you think because they can sometimes have mites living on them. Those are always fun to find when we see them under the microscope
Bugscope TeamMe too...I did my PhD on beetles
- StudentI love learning about bugs
- StudentThanks for your answers!!!!! -Ally Kat
- Studentis that a leg
Bugscope TeamI think this is an antenna....but I am not super sure
- Bugscope Teamif you take the mag down a little we can see just where we are
- Studentdo the bugs have to be dead
- StudentWhy is it that we cant see or feel the hairs on the flies body?
Bugscope TeamThe hairs are just too small to feel.
- StudentWhat is this part?
Bugscope Teamwe are looking at the side of the thorax- where all the legs are attached, and a couple legs
- StudentThats Hairy!
- Teachermag down more?
- Bugscope Teamthis is mostly the ventral side (the bottom) of the thorax of the fly
- Bugscope TeamGAH! I was wrong. Not an antenna...a LEG!
- Bugscope TeamMsG this is great.
- StudentWhat are the hairs on it's body for
Bugscope Teamwell, they are used for feeling things smelling things, sensing wind direction, etc.
- Studentwhat is this
Bugscope Teamthis is the thorax of the fly
- Studentcan u go to the eyes
Bugscope Teamms. gardner has control of the scope, ask her to move to compound eyes, they are very cool looking
- Studentleg
- StudentIs it hard to operate the micorsope?
Bugscope Teamyou could probably learn to operate it well enough in 5 minutes if you wanted
- Bugscope Teamto the top of the screen we can still see part of the head and tongue
- TeacherI'll try
- Studenti did alex
- StudentHow many people operate the telescope?
Bugscope Teamit takes only one person to drive, but there are several of us on line to help when we do a Bugscope session.
- Studentare those the eyes
- Bugscope Teamms. g, try click to center for easier control
- Studentwhere are the eys
- StudentDo u have a picture of a Beetle?
Bugscope Teamwe do have a beetle in the microscope that you might be able to look at today
- Studentwhere r we
Bugscope Teamthe backgound is double stick carbon tape. It will often look bubbly like this. We mount all the insects on it
- 11:06 am
- Teacherwhoooooo!
- Bugscope Teamclick on preset #4 for a mosquito compound eye
- StudentWhy is it that flies have eyes with such an intresting texture on their eyes?
Bugscope TeamThe eyes are made of hundreds of individual facets which gives them that interesting texture
- Studentdo u have a dead snake
Bugscope TeamNope, a dead snake would be too big and too squishy
- Teacherhopw about taking control for a bit?
Bugscope Teamsure!
- StudentOK
- StudentHow many different kinds of bugs do you usually examine a day?
- Studenthi kole
- StudentDoes these bugs have vains
Bugscope TeamInsects have an open circulatory system, which means that their blood is just freely flowing inside its body. It doesn't have veins like mammals do.
- Bugscope Teamthis is where the troublesome insects were that we had to take off
- StudentIt looks as if craters hit the flie like it does on the moon.
Bugscope Teamyes they do resemble moon craters!
- Studentdo you have wasp picturesa
Bugscope Teamwe do have a wasp in the microscope today as well
- Studentis this a leg?
Bugscope Teamyes i think this is the leg of a fly
- Studentwhere is this at
- Studentwhat part is that
- Bugscope Teamthis is a claw
- Bugscope Teama claw on the house fly
- Studentis this a beattle
- Bugscope Teamhere we can see special hairs on the fly claw called tenent setae, which allow the fly to cling to walls
- Studentis that hair
- Teacheris it the end of fly leg?
Bugscope Teamyes, there will almost always be a claw at the end of every leg of an insect, unless we were mishandling them!
- StudentCould you show us the mouth of the flie?
- Studentwhat part of the fly is that
- Bugscope Teamwe are looking at the head of a flay now
- Bugscope Teamand now the mouth area, awith the proboscis
- StudentHow tick is fiy's skin
Bugscope Teamwell, it doesn't have skin, it has an exoskeleton that is very hard for it's size
- Studentr flies really dirty and fat
- StudentWhat is that
- 11:11 am
- Studentwhy does the fly havem hairs on its tung
Bugscope Teamthose are probably chemosensory setae, helping the fly to taste/smell its food
- Bugscope Teamthese are kind of like lips, for the fly
- StudentWhat are the two dots on top of the head if they are not eyes?
- Teacherwow- the maginification is really awesome
Bugscope Teamelectron microscopes can go to MUCH high magnification than light microscopes, which is what makes them so cool
- Studentcan they kill u when your outside
- Bugscope Teamthe ESEM can magnify up to 800,000 times, but for insects like this we only mag up to 40,000 or so
- StudentAbout how long do flies live for?
- StudentWhy do flies make a little buzzing noise?
Bugscope TeamI think that is just the noise that their wings make when they fly around. Some flies communicate with other flies by buzzing.
- Studentwhat is that
- StudentWhat IS THAT!!!????
- StudentWhat is in a insects eye
- Bugscope Teamthis is the base of one of the antennae
- Studentwhat is that!!!!!!!!!!!!!!!!!!!!!!!!! thing
- StudentWhat part of the body is this, the tounge correct?
- Teacheris th is an eye?
Bugscope Teamyes this is the eye! You can see the bumps- they are each call an ommatidium
- Studentis that the eye
- Bugscope Teamnow these are cool, yes this is an eye, a compound eye
- StudentWhat is this
- Bugscope Teamthese are the many facets of the compound eye, called ommatidia, each one has a lens in it
- Studentwhat is that
- Teacher!!!! over 32, 000
Bugscope Teamthis microscope can get to around 200,000x before we start losing a lot of the image quality, but for bugscope we often dont go above 40,000x
- Studentare those deep holes the scratches of the fly
- Studentwhat is the life span of flies
Bugscope Teamwell, i'm not sure, but i think it's just a season or thereabouts
- Studentis this the eye
- Bugscope TeamTick head
- Studentwhat is this
Bugscope TeamThis is a tick
- Bugscope Teamthis is one of the palps on the side of the tick's head
- 11:16 am
- Studentput it to 200000
- GuestWhat am I looking at?
Bugscope Teamthis is a palp on a tick
- Bugscope Teamit's just going to be a blur above 40K or so...
- StudentPut it to900000
- Studentthat loooks so coool
- Studentis this a head or leg
Bugscope TeamWe are looking at part of the mouth
- Studentis this the head
- Bugscope Teamthis is the capitulum, in the middle
- Bugscope Teamthisn is the part that sticks into your skin
- Bugscope Teamfor today, we probably wouldnt see too much of interest at 200,000x-- there just isn't that many small features on insects
- Studentthis looks like a closeup of the moon
- Studentcan you show the hole bug
Bugscope Teamyes, if you lower the mag, ask ms. G to lower the mag
- Teacherhow do they get in your skin?
- Studentis that dirt over the head
Bugscope Teamyes there looks to be some dirt or other type of extra stuff that doesn't belong
- Studentwhat are those things cpming out of the mouth
- Studentwhat do they eat
Bugscope TeamBlood! They feed only on blood.
- Bugscope Teamoh, scott is driving, sorry, my bad
- Teacherok
- Studenthow do ticks suck your blood and streach out so big
Bugscope TeamThey have very flexible stretchy skin in their abdomen. When they fill up with blood, their cuticle can stretch.
- Teacherok again;0
- Studentare insects always this bumpy
- Bugscope Teamthis is where the tick cuts into your skin
- Bugscope Teamnow this is the mouth area of the tick
- StudentHow come they dont hurt when they bite you
Bugscope Teamwell, probably because if they did hurt, we'd smack the tick and it would die, so the smaller ones that don't hurt seem to survive. it probably wants to get its food source without bothering the host
- Studenthow do ticks go through skin so easily
- Studentthis is so amazing !
- GuestI never thought ticks were THIS disgusting
- Studenthow big can a tick get
- Bugscope Teamthis side has recurved spines that keep the capitulum secured in your skin, and on the other side it has a rasping surface
- Studenthow much blood can they eat
- Studentshow the legs
- Studenthow big can a tick get
Bugscope TeamSome of the soft ticks are about the size of a pencil eraser when they are full of blood.
- Studentdoes the tick feed off your skin
Bugscope TeamIt actually digs its mouth into the skin and feeds from your capillaries
- Studentoh, THAT is how they hold on Thank you
- Studentwhat do the feet look like
- 11:21 am
- Studentthose are long legs
- GuestWhat are those circular things around the mouth
Bugscope TeamThose are palps
- Studentthis is so cool
- Studentis that like a finger print
- Studentwhat is that
Bugscope Teamthey are pollen grains!
- Studenthow come the microscope does not have any color?
Bugscope Teamthe microscope uses electrons to get the image, not light. since color is based on the frequency of LIGHT, and since we aren't using light to get the image, there is no color
- Studentwhat are these
- Studentthats scary
- Bugscope Teamthis is pollen; the part that looked like a finger print was the surface of the body, which can swell to a much larger size when the tick easts
- Bugscope Teameats
- Teachernicholas asks - where is the nose?
Bugscope Teamit does not really have a nose, but it has sensory pits on the other side of the head where we cannot see them
- Studenthello! anna in the house!
- Studentwhat are those?
- StudentHi
- Studenthello
- StudentHi
- Studenthi greace has joined the party
- StudentI had a tick in my head it took 20 mins to get it out.....
Bugscope Teamyeah it can be creepy when you find a tick on you. I found 2 on me once- no fun at all
- Studenthello
- Studentwhatsthat
- Studenthow bad do you think it hurts when they bite you
Bugscope Teamit doesn't really hurt at all when they bite. You can't really feel it. It hurts when you have to pull them out. Sometimes the bites get infected or really itchy
- StudentAwsome!!
- Studentwhat is that
- Studenthow much blood do they drink each minyte?
Bugscope TeamNot very much. I believe they feed very slowly
- Studentis it a female?
- Teacheryeah, we want to see the end of the leg - yes...
- Studentone time when I got 200 ticks in my head it did not hut until 30 minuetes later how come
- StudentWOWWWWWW
- StudentUuch!!!
- Studentwoww
- Studentcool
- Studentcool
- Studentdo ticks need that stringy texture for a reason
- 11:26 am
- Bugscope Teamocellus, one of three
- Studentwhy are there hairs
Bugscope Teamjust about anything that looks like a hair on an insect is called a seta (setae plural), and those are to help the insect sense its environment
- Studentwhat are we looking at?
- Studentwhat part ove this is it
- Studentbye
- Studenthey
- Studenthi
- Studentis that a leg
- StudentHello!!
- Studentpease
- Studentwhat is that
- Studentwhat is this
- Studenthi
- Studentwhat in the world is that
- Bugscope Teamthis is the antenna of the wasp up close
- Studentwhat do they eat
Bugscope TeamMost wasps eat other insects. They will also feed on nectar and sticky stuff.
- Studentewww what is sticking out of the holes
- Studentwhat is that is this still the waps
- Studentlight them on firer
- Studentwhat are those spikes
Bugscope Teamthose are all setae (insect hairs)
- StudentEWWWWWWWWWW
- Studentwhat is in that hole
- Studentwhat is this
- Studentwhat is thiss
- Bugscope Teamthey are on the wasp
- Studentdo they live in the groung?
- Bugscope Teamantennae it hink
- Bugscope Teamthink*
- TeacherBj asks what was that
Bugscope Teamthey were special setae on the wasp antennae
- StudentDo these setae fall out and grow back in?
Bugscope TeamNo, if they lose a setae or a wing or a leg, they will not grow it back
- Bugscope Teamthat was a wasp antenna, very close up
- Studentwhat do they eat
Bugscope Teamstink bugs feed either on plant juices or other insects
- Studentwhat in the world is that
- Bugscope Teamah cool, this is a stink bug
- Studentcan you show a spider
- Studentthis is so awesome
- Bugscope Teamthose round objects on the side of its head were it's compound eyes
- Studentnice!!!!!!!!!!!!!!!!!!!!!!!!!!!1
- Studentcoooollllll
- Studentshow the eyes
- Studentwhat is that white paper
- Teacherok - hate to stop, but time for classes to go now....
- Studentwhat is that
- Studentwhat is that
- 11:31 am
- Bugscope Teamthanks you, you all asked great questions!
- Studenthow do stink bugs make that bad smell
Bugscope Teamthey have glands at the base of their legs that secrete the smelly juice
- Studentsee ya
- Studentthank you
- Bugscope TeamSee ya!
- Studentbye and thanks
- Studentbye and thec
- Studentthis is sweet!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
- Studentare thoes vanies
- Studentccoll!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
- Studentthere are little bumps
- Studentwhat are thous
- Studentthis that a eye
Bugscope Teamyes it is
- Studentwhats that
- Bugscope Teamthese are compound eye facets (ommatidia) on a mosquito, they are deflated a bit
- Bugscope Teamthat is the substructure of the mosquito eye
- Studenthow many eyes do bees have
Bugscope Teamthey have a total of 5- 2 compound eyes, and 3 simple eyes called ocelli
- Studenti know
- Studentcccoooollll
- Studentby
- Studentis that hare
Bugscope Teamthese are mosquito scales
- Bugscope Teamnot hair, setae (see-tee)
- Studentcool
- Studentcool
- Studentis that a wing
- Studentwow
- Studentis that a wing
Bugscope Teamthese are scales on the mosquito's leg
- Studentwhat is that
- Bugscope Teamthis is part of a wing
- Studentwiy are they poyt
- Studentok
- Studentgo to 200000
- Bugscope Teamscales are similar to the feathers on abird
- Studentmy cool teacher is here gtg
- Bugscope Teamoops Cate is right this is not part of the wing
- StudentWhat is this
- Bugscope Teamscales can be found on butterflies, moths, mosquitos, and some beetles
- Studentmy teacher is here
- Student whom im i spike to
- 11:36 am
- StudentWhat do they eat
- Studentwhy are there little flakes on the bug
- Studentwhat is that
- Student i am go ing bye
- Studentpeas out!!!!!!!!!!!!!!!
- Studentplease go to 200,001
- Studentwhats is up
- Studentmy awsome teacher is here, mr awsome is out
- Bugscope Teamlater mr awesome
- Teacherthe teacher is really here. sorry for wayward comments. my computer is very slow now.
- Bugscope Teamok, bye bye, we are closing down the session
- Bugscope Teamwe will see you on Friday
- Bugscope Teamhey no problem at all
- Bugscope Teamsee you Friday!
- Bugscope Teamover and out
- Teachergreat! see you friday!
- Bugscope Teambye bye
