- 12:00 pm
- Bugscope TeamTony should be able to get on now, right?
- Bugscope TeamI can call him.
- Bugscope Teamyep, tony can login now.
- Bugscope Team1.5 on the vac, real close
- Bugscope TeamCate says 1.5...
- Bugscope Teamyes, 1.5
- Bugscope Teamscott, can you hear me?
- Bugscope Teamd'oh
- Bugscope Teamuh no
- Bugscope Teampsst
- Bugscope Teamoh now I can
- Bugscope Teamare we there yet/
- Bugscope Team1.5 still
- Bugscope Teambeetle effect
- Bugscope Teamit's had a week though, to dry out
- Bugscope Teamguess it would've been worse
- 12:05 pm
- Bugscope Teamunless we closed a hair (not a seta) in the door
- Bugscope Teamis it still 1.5?
- Bugscope Teamsheesh
- Bugscope Teamso, if a hair gets stuck in the vacuum seal, the symptoms are the vac goes down, but never quite reaches acceptable leves?
- Bugscope Teamwe are still at 1.5
- Bugscope Teamyeah it cannot quite get there
- Bugscope Team6 of em, yep
- Bugscope Team1.4
- Bugscope Teamclose
- 12:11 pm
- Bugscope Teamdang
- Bugscope Teamstill 1.4, we'll make the presets fast
- Bugscope Teamwhat's the score now, are we there yet?
- Bugscope Team1.3....
- Bugscope Team1.3 intermittent!
- Bugscope Teamjust waiting for vac okay now
- 12:17 pm
- Bugscope Team1.4 again
- Bugscope Teamnope, went back to 1.4
- Bugscope Teamshould we open and take out some bugs?
- Bugscope Teamventing, and trying again
- Bugscope Teamhello mrs. dimaso!
- Bugscope Teamwelcome to bugscope
- Bugscope Teamwe are setting up still, putting bugs in the scope and waiting for the vacuum, and then we'll make some presets
- TeacherHello from Dr. Clishem (Tony), Mrs. DiMaso (Caroline) and Mrs. Mitchell (Pat)
- 12:22 pm
- Bugscope Teamwe start at 12:45 right?
- Bugscope Teamscott is working on the scope, getting the vacuum set, and then we'll make presets, and then i'll unlock the session, and then you can start!
- Bugscope Teamone thing to note when using the Navigation tool, is when you Drive you click once to start moving, then click again to stop.
- Bugscope Teamsometimes it is difficult to get the hang of "driving", so if you have problems with it, try using "Click to Center" instead. this will allow you to click once, and the scope will move to that position.
- Teacher12:45- 12:50 is the start time. I have 28 kids--Should all 28 be allowed to chat or would you prefer that I pair them up to cut down on traffic?
- Bugscope Teamwell, i think we can handle 28 at a time, but it might get a little hard to answer if we get 28 questions at once. maybe pairing kids up is a good idea? 2 kids to a computer? but, it is up to YOU as the teacher how you want to do it. we will try to accomodate.
- Bugscope Teamdo you have 28 computers?
- TeacherWe'll go with having them work in pairs.
- Bugscope Teamokay, sounds cool.
- 12:27 pm
- Bugscope Teamwe are having a little trouble getting the vac down on the scope, so we are a little behind, we will be in time though, for starting at 12:45-12:50.
- TeacherThis is Tony . . . I will be leaving half way through the session, but Ms. DiMaso feels pretty confident about the whole thing. The controls look different. Are they easier than before?
- Bugscope Teamsome bugs have air pockets in them, and so the vacuum doesn't work all the way, so we have to take some bugs out, close the scope again, and try the vacuum again.
- Bugscope Teamyes, the interface is much better than before.
- Bugscope Teambut keep in mind what i said before about navigation. click to center is easier than driving.
- Bugscope Teamyou can see now we are openinig the scope to fix the bugs.
- Bugscope Teamthat's scott
- Bugscope Teamnow we took out a bad bug and are trying the vacuum again.
- Bugscope Teamwhen controling the scope, just remember there is a slight lag in every operation. when you click on a control like moving or adjusting the focus, try clicking once and wait for the change, and once you get used to the speed of the interface, it does work well.
- Bugscope Teamwe tried to make the interface as close to what controlling the real ESEM is like.
- 12:36 pm
- Bugscope Teamokay what's the score now 1.5?
- Bugscope Teamwe are waiting for 1.3 x 10-4 mBar
- Bugscope Team1.4
- Bugscope Teamso we can bring up the beam and grab the presets
- Bugscope Teama lot of pressure on Cate to get the presets done
- Bugscope Teamgood thing she is tough
- Bugscope TeamChas rewrote the software, and he has been with us since the very beginning. So he knew what to do...
- Bugscope Teamcate is the champ!
- Bugscope Team1.3
- Bugscope Team1.3...
- Bugscope TeamHere we go.
- Bugscope Teamstarting the presets. we will be ready in 8-10 minutes
- TeacherDid Chas start in the mailroom only someday to become CEO of the company? --Tony
- Bugscope Teamheh. well, not the mailroom exactly, more like started as an intern.
- Bugscope TeamChas started as free labor in high school as a sophomore.
- Bugscope Teamnow he is a grad student in bioengineering.
- Bugscope Teamkind of like Blade Runner.
- Bugscope Teampalp
- 12:41 pm
- Bugscope Teamlooks like a jet engine
- Bugscope TeamChas works for the Terrell Corporation.
- Bugscope Teamwing
- Bugscope Teamheh
- Bugscope TeamTony where are the kids?
- Bugscope Teampollen grayne
- Bugscope Teamthey said the kids are coming at 12:45-12:50
- Bugscope Teamgrayne i mean?
- TeacherThey are here and we are watching the presets and seeing the chat. They have not logged in yet.
- Bugscope Teamtell Cate she's doing a good job.
- Bugscope Teamgrain
- Bugscope Teamyou can see brochosomes
- Bugscope Teamhi kids, welcome to bugscope!
- Bugscope Teamthis is odd -- we're giving away all the presets
- Bugscope Teamstudents, i mean.
- Bugscope Teamthis is a louse, courtesy of one of Kendra's children.
- Bugscope Teamjuju
- Bugscope TeamYay Claudi is here.
- Bugscope TeamHey everybody
- Bugscope TeamCal
- Bugscope Teamyou can go ahead and have the students login if you want. we will be ready very soon.
- Bugscope TeamClaudi we are doing the presets.
- Bugscope Teamone more preset...
- Bugscope TeamARe those bugs sent by the teacher?
Bugscope Teamno, these are bugs we had.
- 12:47 pm
- Bugscope Teamokay, we are ready!
- Bugscope TeamWELCOME TO BUGSCOPE!
- Bugscope Teami have just unlkocked the session mrs. dimaso, you can start controlling the scope now.
- Bugscope Teamwhen you have questions, go ahead and ask away
- Bugscope Teamwe can also give control of the scope to any of your students, if you should want that.
- Bugscope Teamalright we are ready to roll
- Bugscope TeamWhat grade is this?
- Bugscope TeamAnnie is in class today, so she cannot help, but Smiley (Claudi) is here.
- Bugscope TeamI will try my best =)
- Bugscope TeamMaybe someone can tell us what grade we're working with?
- Bugscope Teamgrades?
- StudentWe are in 5th grade.
- Bugscope TeamHi Shelley!
- Studentwhat are we looking at
- Bugscope TeamCool Samanth and Sarah thank you
- Bugscope Teamthis is the compound eye of some sort of flying insect
- Bugscope Teamthe individual facets of the eye are called ommatidia.
- Studentwhat is the magnification?
- Bugscope TeamShelley are you working with us tomorrow?
- Bugscope Teamyou can see the mag a the top right, it is currently 2797X
- Bugscope TeamMrs Dimaso has control of the 'scope now.
- 12:52 pm
- Bugscope Teamas you can see, those eyes are pretty big
- Bugscope Teamnow you can see where we were.
- Bugscope Teamthey take up the entire side of the head
- Bugscope Teamlooks like this guy has four wings, like a wasp
- Bugscope TeamHow about contacting one of the drosophila labs...should be easy to do...don't you think Scott?
- Studentwhat is this little creature
- Studentwhat's the white stuff on it's eyes
- Bugscope TeamI think it's a small wasp
- Bugscope TeamAlex: How do I do that?
- Bugscope Teamwhen you take up the mag a lot on an insect, you will often see small pieces of debris like dirt all over them, some more than others
- StudentHow did you put it in there
- Bugscope Teamsmiley, press the tilda key.
- Bugscope Teamthere is a moire pattern on the eyes
- Bugscope Teamshould be the key to the left of the number 1
- Bugscope TeamCate made the sample and stuck this little wasp onto the carbon doublestick tape
- Bugscope Teamshe also stuck it down with silver paint
- Bugscope Teamyou should be able to see how the hind and fore wings connect.
- Bugscope Teamthere are tiny hooks there called hamuli.
- Bugscope TeamLook at all those fine hairs (setae) on the wings!!!
- 12:57 pm
- Bugscope TeamThey are receptors that allow the insect to better navigate through the air
- Studentwhat are those hooks for
- Bugscope Teamsome insects with four wings have the ability to hook the hind and forewings together in flight. It makes them more efficient when they fly.
- Bugscope Teammy favorite is earwigs.]
- Studenthow fast can a wasp go
- Bugscope Teamfocus getting better and better
- TeacherHow do I change bugs?
Bugscope Teamyou can click on a preset, that will take you to another bug, presets are in the lower right corner
Bugscope Teamif you can't see the presets, try expanding your browser window to full screen (F11).
- Studentare the little hairs on the bug painful if you touch it
Bugscope TeamSome of the setae might be so fine and delicate that we may not even feel it through our skin.
- Studentis the stinger still in the wasp
- Bugscope Teamthe hairs (setae) are so tiny you cannot feel them
- Bugscope Teamyou can, Mrs D, select a new preset from those on the right
- Bugscope Teamyou can look and see if you want by driving down
- StudentWhy are the hairs spirel?
- Studentdo most bugs have hair
Bugscope Teamyes, most bugs have hair, which we call setae, those setae help the bugs to sense their surroundings.
- Studenthow many hairs are in the wing
Bugscope TeamThere are likely millions of them. But if I am not mistaken the number of setae may vary between different insects
- Studentwhat are the white things on the wings?
Bugscope Teamthose would be brochosomes, which is something only leafhoppers make
- Bugscope Teamspiral hairs do not flew as much in a particular direction -- the spiral shape makes them more rigid.
- Bugscope Teaminsects really rely on those setae a lot so they can sense their environment, they have hard shells (exoskeletons) and not soft skin like us
- 1:02 pm
- Studentwhat do they eat?
- Studentwhat bug do u like the most
- Studentdo the hairs grow
Bugscope Teamnope, they are fixed.
- Studentwhat are those things stiking out of them
- Studentwhat type of bug is that?
Bugscope Teamthis is a louse.
- StudentWhat are those little tiny things
- Studentdo the presets have teeth
Bugscope TeamPresets are favorite sites the bugscope team marked, so that your teacher canjust click on them, to look at it
- StudentWhy are the hads have cringes in the arms
- Studentwhat is the stuff coming out of the louse
Bugscope TeamSetae...is what "comes out" off the louse
- Studentwhat does they are fixed mean (how are they fixed)
Bugscope Teamthey are attached to muscles and nerves under the shell, so they don't grow or move, but they can fall off sometimes.
- Bugscope Teamthis is a louse, from small children
- Bugscope Teama louse is what the word lousy comes from
- Bugscope Teamplural is 'lice'
- Studentin real life how big is the louse
Bugscope TeamProbably about the size of a pencil tip, anybody if I am wrong please correct me.
- Bugscope Teamlice are small bloodsucking arthropods that get in your hair
- Bugscope Teamit's only a few mm long, very small
- Studentdoes the lice hurt them
- Studentdo they lay eggs
- Bugscope Teamsome of the setae extend through the exoskeleton and are attached to nerves
- Bugscope Teamlice just makes your head itch
- Bugscope Teamthey lay eggs on your head, and new ones hatch out
- Bugscope Teamthey lay eggs in your hair with some gooey stuff so they don't fall off
- Studenthow do you get lice
Bugscope TeamFor example from someone who has lice
- Studentdo the louse have hair on it
Bugscope Teamyes, lice do have hairs (setae) as well.
- StudentHow do they put the lice on the microscope, where did you get them?
Bugscope Teamall bugs have to be preped before they go into the microscope, that involves coating the bug with gold palateum, and then taping the bug to a stage, and then putting it in the scope and turning on the vacuum.
- 1:07 pm
- Studentis part of that leg cut off
- Bugscope Teamyou can catch them from kids that have them -- if the kids have not come from a clean environment
- Bugscope Teamsome households are not as clean as others
- Studentwhere do the lice live beside's hear
Bugscope TeamThere are different types of lice, some live on people, and then I think there are lice that live on trees. The ladybugs eat those.
- Studentwhats the gooey stuff
Bugscope Teamit's their own saliva
- Bugscope Teamlice have features that allow them to attach to hair on your body
- Studentwhat is the stuff piling on the louse
- Studentwhy is there so little hairs
- Bugscope Teamlike they have little clinging limbs that grasp human hairs
- Studentwhat do they eat
Bugscope Teamlice will eat dead skin, or even blood. the color of a louse can change slightly depending on what it is eating. if it eats blood it will become darker.
- Studenthow many bugs do you guys look at a day
Bugscope TeamI work with Praerie voles (mammal)...but help out with Bugscope...that's when I look at bugs.
- Bugscope Teamwe do not always look at insects and arthropods
- Bugscope Teamjust, mostly, for bugscope sessions like this
- Studentwhat kind of bug is that
- Studentis that hair too
Bugscope Teamwell, yes, it's hair or setae.
- Bugscope Teamor lightning bug whichever you call it
- Bugscope Teaminsects tend to be a lot hairier than you would think
- Studentwhere do the light come from
Bugscope Teamdo you mean in the image? the image is taken by gathering electrons that are being shot off the bug inside the microscope.
- Studentin the bug
- Bugscope Teamwe are using electrons that come down from above the sample
- 1:12 pm
- Bugscope Teamthe electrons arrive in an electron beam
- Bugscope Teamthey glow because of a chemical reaction with their organs
- Bugscope Teamand they scan continuously across the sample
- Studentno the light in the bug that u see at night
Bugscope Teamah sorry, yes, cate says it's a chemical reaction that causes the firefly to light up.
- Studentwhere dose it glow on this fire fly
- Bugscope Teamyeah the light in the lightning bug comes from the abdomen, sorry
- StudentAre the things coming out of it hair
Bugscope Teamthe light is coming from within it, from a chemical reaction with their organs
- Studentwhat is the spickes with the balls on top
- Bugscope Teamyou'll notice the brochosomes on here too
- Bugscope Teamscott is controlling the scope, focusing.
- Studentwhere is the light on the bug
- Bugscope Teamthose small balls are called brochosomes
- StudentWhat are the little white balls
Bugscope Teamthose are called brochosomes
- Bugscope TeamI don't know much more than that
- Studentwhat does the claw do????
Bugscope Teami think claws can do all kinds of things for the bug, like scoop food into it's mouth for example.
- Bugscope Teamthe brochosomes are something only leafhoppers produce
- Bugscope Teambrochosomes are small waxy balls, sometimes shaped like footballs, that leafhoppers put on their bodies, and on their eggs to keep them from drying out.
- Studentwhat type of microscope are you using
Bugscope Teamthis are images from an Environmental Scanning Electron Microscope (ESEM).
- Studenthow many of those balls do the bug have
- 1:18 pm
- Studentare the bugs frozen?
Bugscope TeamBefore we can use them with the microscope, they must be dried
- TeacherCan you focus on the white ball for us!
Bugscope Teami can't seem to focus on it, too high of a mag maybe?
- Studentwhere do you get all the bugs
Bugscope TeamBackyard, on the way home from work, whereever you can find bugs...
- Bugscope Teamscott is working on the mag now.
- StudentWhat are the little circles in the ball's?
- Studentwhat are those line things
Bugscope TeamI think they are setae...at least I hope that's what you mean by line things
- StudentHow big is the bug
- Bugscope Teamit's kind of like a whiffle ball
- Bugscope Teamyou've seen a firefly before right? it is about an inch big
- Bugscope Teamokay I am back
- Bugscope Teamthe balls are sticking to its "hair" or what we call setae (seta for singular)
- StudentWhat does the light on the firefly feel like?
- Bugscope Teamthat big ball right there is a grain of pollen
- Bugscope Teamthis is cool -- this is a pollen grain, much larger than the brochosomes
Bugscope TeamWow...I did not know that pollen grains can have different shapes.
- Bugscope Teamthis is on the wing of a lacewing bug
- Bugscope Teamthe firefly light is cool to the touch
- Studentwhat is a lacewing???
- Bugscope Teamthose are those green bugs with long transparent wings
- Studentwhats the hairy things on its leg
- Studentwhat is the smallest bug u have and can we look at it later
- 1:23 pm
- Studentis it a leaf
- StudentIs that a leaf or a wing
- Bugscope Teamthis is a wing
- Bugscope Team some of them can bite people, although they are too small to eat them
- Bugscope Teamand it looks very hairy
- Studentwhat are the bubbles on the outside
Bugscope TeamBubbles in the carbon tape, used to afix the bugs to the little holder which is placed inside the microscope
- Bugscope Teamthis is the wing
- Studentwhat are the lines and cracks?
- Bugscope Teamthe bubbles are dirt or grease
- Bugscope Teamthe lines are the veins of the wing
- Bugscope Teamsort of like the wooden sticks that are the rigid members of a kite
- Studentisit a leaf bug?
- Bugscope Teamthis is a lacewing -- a flying predatory insect
- Bugscope Teamit eats other bugs
- Bugscope Teamit's not a leaf bug as in a leaf mimic
- Studentwhy do the wings have viens
- StudentWhy are some parts of the wings darker then other parts?
- Bugscope Teamthe veins support the structure of the wings
- Bugscope Teamsome parts send less signal to the secondary electron detector
- Studentwhat is this ball ror
Bugscope TeamThe ball is pollen. Many plants depend on pollen to more plants to fertilize flowers to produce fruits such as appleas, cherries.
- Studentwhat are the smaller balls around the grai of pollin?
- Bugscope Teamwhen we go to super high mag like this it is difficult to get good resolution because we are not very close to the sample -- we are nearly an inch away inside the 'scope
- Studentwhat are the dots on the bug
- 1:28 pm
- Studentdont viens hold blood and y would a wing need blood if it's flat
- StudentWhat is the fuzzy stuff on the bug, why is it fuzzier on that big line
- Bugscope Teambees carry pollen from flower to flower
- Bugscope Teamthe fuzzy stuff was tiny setae called microsetae
- Bugscope Teamsometimes the microsetae form a pattern or a color
- Bugscope Teamwe think they also provide surface area to give the wing more lift in the air as the insect flies
- Studenthow did you get the job
Bugscope Teammost of us went to college and have degrees in science or related fields, and we are all interested in microscopes and imaging.
- Bugscope TeamI started out as an English major and then added biology
- Studentwhen did you know you wanted to be a scienetst
- Bugscope TeamI started doing electron microscopy when I was almost out of college.
- Studentwhat experemts r u working on
- StudentWhat kinds of stuff do you do that is fun?
Bugscope TeamBugscope with classes like you =) I like sharing science with others.
Bugscope Teami like playing cards with friends, reading cool books about science fiction, riding my bike, etc.
- StudentDid you like bugs as a kid?
Bugscope TeamTo be honest, I like bugs under the microscope much better. It is amazing to see the structures that you could not see with your eyes alone.
- StudentWhat grade did you start to like science?
- Bugscope TeamI liked bugs as a kid
- Bugscope TeamI just liked science in general and ended up choosing physics as my major, I got this job from a friend of a friend
- Bugscope TeamCate is a nerd.
- Bugscope TeamI've always liked science, some bugs kind of creep me out, but only the live ones, I can handle them when they are dead
- Studentwhat is ur favorite thin to do
Bugscope Teamswimming is pretty cool, what about you?
- 1:33 pm
- Bugscope TeamI read, go to art museums, sometimes collect chairs
- Studentwhy are the hairs on the bug
Bugscope Teamthe hairs are called setae, they are for helping the bug to sense its environement.
- StudentAre those hairs on the bugs?
- Bugscope Teamthe hairs (setae) allow the bug to feel or smell its environment through its exoskeleton
- Studentwhat is that light grey thing
- Bugscope Teamwhat kind of sports? basketball, baseball, football?
- Studentwhy is part of the bug white and powdery?
- Studenthow many legs does it have
- Bugscope Teambugs have their skeleton on the outside, sort of like armor
- StudentHow many cells are in this bug? We looked at 1 cell.
- Bugscope Teamso they need to be able to sense their surroundings through the chitin, or cuticle
- Bugscope Teamthere are thousands of cells even in something so small
- Studentwhat is your favorite bug?
- Studentwhat is the smallest bug u ever looked at????
Bugscope TeamMites living on an earwg
- Bugscope Teamearwigs are my favorite because they often have mites
- Studentthank you
- Bugscope TeamScott is right, there are a lot of cells making up some of the long setae you saw earlier
- StudentThankyou Goodbye.
- Bugscope Teammites are not strictly insects, but they are very small
- StudentThank you soo much we really appriciate it.
- Studentare they blind?
- Studentthanks and good bye
- Bugscope TeamOh you are leaving?
- Bugscope Teamgreat questions
- StudentThank You!goodby!
- Bugscope Teamthanks guys
- Bugscope TeamBye...it was fun
- StudentThank you, good bye.
- Studentthank you for your anwers, good bye
- StudentThanks for answering all our questions! Bye!
- Bugscope TeamThank YOU!
- TeacherOur 5th Graders LOVE science and want to thank all of the scientists for showing us these cool bugs!! Thanks!!!
- Bugscope TeamBye, see you next year?
- Studentthank u very much, Phil and Justin and that was a awsome thing to look at!
- Bugscope Teamyou are very welcome!
- Bugscope TeamWe always have fun doing this and look forward to seeing you again.
- Studentbridget wants to be a bugologest
- StudentThank you a lot.
- Studentthank you for taking all of our Qs bye
- TeacherWe do bugscope every year! See you next fall!
- GuestWhat kind of insect are we looking at?
- Bugscope Teama bugologist is also called an entomologist
- Bugscope Teamthis is a beetle
- Bugscope Teamthis is a beetle we found in our hallway
- Studentthanks for tanking time to talk to us bye
- Studentsee you guys next year
- Bugscope Teamoutside the lab
- Bugscope Teamsee you next year then, keep it real!
- Bugscope Teamsap let us know if you would like to drive the 'scope
- 1:38 pm
- Studentthank u very much goodby
- Bugscope TeamI just gave you control.
- Bugscope TeamSo sap you should now be able to see that you have presets to the right and controls to the upper right.
- Bugscope Teammrs. dimaso, do you have any remaining question? you can view the entire transcript of your session at your member page, it also has pictures from the session: http://discord.itg.uiuc.edu/members/2007-051
- Bugscope Teamplease try something like changing the mag or clicking on a preset
- TeacherThanks! We're done for today! We will look forward to reading the session script!!!!
- Bugscope TeamShelley are you there?
- Bugscope TeamThanks Mrs DiMaso!
- Bugscope Teamthank you mrs/ dimaso, talk to you later, and see you next year too!
- Bugscope TeamHi Ben.
- Bugscope TeamShelley you are free to drive if you would like.
- 1:44 pm
- Bugscope Teamor sap you are free to drive.
- Bugscope Teamshelley might be away from keyboard for a moment...
- Guestthanks, WE'll see u tomorrow.
- Bugscope Teamshelley = sap?
- Bugscope Teamokay, see you tomorrow!
- Bugscope Teamwell, that's it, closing the session.
- Bugscope Teampeople, i'm closing the session,l any objections?
- Bugscope Teamcate: i concure.
