- Bugscope Teamjeff! welcome!
- Bugscope Teamwe are setting up presets for your session
- Bugscope TeamJeff! Yay!
- TeacherI am in. Thank you Scott, jeff
- Bugscope Teamso Dude we are setting up presets for your session.
- Bugscope Teamnothing will work quite yet, for you, but you for sure can chat with us
- Bugscope Teamonce we get the presets made we can let you have control of the microscope
- TeacherScott, Will it be permissible for the students to login on their computers as well? Jeff
Bugscope Teamtotally. we prefer that actually
- Bugscope Teamabsolutely!
- Bugscope Teamwe've got the session locked now. once we are done with presets, we'll unlock it and then you'll see microscope controls on the right
- Bugscope Teamthey will go to the same place and log in as Students rather than Teacher
- Bugscope Teamjust have the students goto: http://bugscope.beckman.illinois.edu/live, and login as a student, no password
- TeacherGreat thank you .
- Bugscope Teamthe students will not need to use a password
- Bugscope Teamyou're welcome jeff
- 4:32 pm
- Bugscope TeamJeff you can start to see what's going on now.
- Bugscope TeamWe are making preset positions for you to choose from once the session gets started.
- TeacherJust a questions, How do I know what I am looking at. Will a presentation be given to start.
Bugscope Teamalso, try clicking on the scale bar in the lower left of the image, you'll see a lot of information about what you are looking at
- Bugscope TeamYou can click on a preset, or you can drive the microscope freehand.
- Bugscope TeamYou can give a presentation and let your students know what's going on -- tell them what Bugscope is.
- Bugscope TeamIt is fairly intuitive.
- Bugscope Teamthis is a resource the teachers will be able to use in order to introduce their students to microscopy, or to insects, or to science..
- 4:37 pm
- Bugscope Teamscott's right, the students will start asking questions themselves, sometimes it gets pretty busy
- TeacherThis is the best use of technology I have seen yet. I thought regular microscopes were fantastic. Wow.
- TeacherHow many presets will there be?
Bugscope Teamwe normally do 15-20 presets a session
- 4:43 pm
- Bugscope Teamyou will have control over the microscope once we unlock the session -- once we're done with the presets
- Bugscope Teamyour students may log in anytime, and they will be able to ask us what's going on -- so you can sort of hang back if you want once you've given them a brief intro
- Bugscope Teamwe can confer control of the microscope to anyone else, like a student
- Bugscope Teamonly one at a time, of course
- Bugscope Teamit wouldn't be so good to have many people trying to drive at one time
- Bugscope Teamthis is a $600,000 scanning electron microscope, and we have been running Bugscope with it since March 1999
- Bugscope Teamso we have done around 500 sessions
- Bugscope Teamthis is salt from a Wendy's restaurant
- Bugscope Teamwhat is going on right now is Chas is driving the microscope, finding cool stuff, and Alex is running the computer with the Bugscope server hooked up to it, inputting the presets as Chas locates ones he likes....
- 4:48 pm
- 4:54 pm
- 5:02 pm
- Bugscope Teamokay, i just unlocked the session, you should see controls on the right side of the image
- 5:11 pm
- Bugscope TeamJeff!
- Bugscope TeamDude!
- Bugscope TeamYou may start driving now if you wish.
- 5:16 pm
- Bugscope Teamjeff, when you get back, we are ready anytime
- Bugscope Teamwas that you? cool!
- Bugscope Teamany questions at all just let us know
- Bugscope Teamthings
- Bugscope Teamgood work jeff! click once to start moving, then click again to stop. right on dude!
- TeacherIf I can control this a two year old can.
- Bugscope TeamJeff! How are you doing? Try taking the mag down.
- Bugscope TeamYou'll see where you are.
- Bugscope Teamand try clicking on the scale bar in the lower left, that'll bring up a cool info key
- 5:22 pm
- Bugscope Teamthis is a true bug -- Hemiptera
- Bugscope Teamyou can see one of the compound eyes
- Bugscope Teamlower left
- Bugscope Teamoh hello Chas 2
- Bugscope Teamthe sequel
- TeacherMy students are arriving and beginning to set up and get in.
- Bugscope TeamCool!
- Bugscope TeamThey should be able to go to bugscope.beckman.illinois.edu and log in as Students
- 5:28 pm
- Bugscope Teamhi kellie, welcome to bugscope!
- Bugscope Teamhi megan1
- Bugscope TeamHi Kellie, and Megan1!
- Bugscope Teamwelcome to Bugscope!
- Guesthows life
- Bugscope Teamgood good, you?
- Bugscope Teamwe are making noise down here
- Guestwhere are you guys? we're in a classroom
- Bugscope TeamPretty relaxed here; got some music on for the after-hours session
- Bugscope TeamBasement. You win
- Guesthave no idea what this is.
- Bugscope Teamwe are 23 feet underground in the middle of serious nowhere
- Bugscope Teamwe are in illinois, in the basement of the beckman institute
- Bugscope Teamthis is the edge of an eye of a spider
- Guestim from chi town
- Bugscope Teamcorn belt USA
- Bugscope Teamgo bulls!
- Bugscope TeamWe're looking at some hairs, called "setae", around the rim of a spider's eye
- Bugscope Teamda bears
- Bugscope Teamshould we give you control, Megan?
- Bugscope Teamwelcome annamarie, mristen, akr, welcome
- Bugscope TeamJeff is driving now...
- Guestseriously, what is this site
- Guestmy teacher told us to log on ...were in college
- Bugscope Teamgreat, this is bugscope, where students can control an electron microscope over the internet
- Bugscope TeamYou're logged into a website that gives you interactive control over a half-million dollar electron microscope
- Guestoh wow.
- Bugscope TeamSo only one person can control at a time and currently Jeff's got control
- Guestannamarie, join this convo
- GuestJeff is my teacher?
Bugscope Teamum yeah
- Bugscope TeamThis is something we do with about three class-rooms a week, at schools all over the world
- Guestyes, i think jeff is our teacher.
- Guestconsidering we're in the same class haha
- Bugscope Teamheh
- Guestso what are we looking at
- Guesthair follicles
Bugscope Teampretty much. these are little hairs- called setae
- Bugscope Teamokay Megan we are giving you control.
- Bugscope TeamThese are some hairs, "setae" in insect parlance, around a spider eye
- Guesti have control what does that mean
- Bugscope Teamyou should see controls to the right of the images
- Bugscope TeamThis is an education outreach activity we run free of charge with schools that apply.
- 5:33 pm
- Bugscope Teamand you can also click on one of the presets if you want the microscope to drive to that place
- Bugscope Teamlike that...
- Guestmegan is sucking at this so far
- Bugscope Teamif you want to change the mag to see where you, for example, click the mag button lower
- Guestoh wait, thats cool
- Bugscope TeamThis part is super-cool, we've never seen anything like this before
- Bugscope Teamthis is pretty cool, yeha
- Guesthow do we know what it is?
Bugscope Teamyou would ask us, and we should also have named it since it is a preset
- Bugscope TeamWell, that's sort of a boot-camp introductio into science: we don't always know what we're looking at ;)
- Guestgive control to jeff
- Bugscope Teamokay Jefff is the supreme ruler
- Bugscope TeamHe's got it
- Bugscope TeamI mean Jefffff
- Guest(he got mad)
- Bugscope Teamthis is the tip of the proboscis of the moth
- TeacherScot can you tell they are like little children again.
Bugscope Teamheh, yeah
- Bugscope TeamThese are mystery structures on the under-side of the coiled-up proboscis
- GuestHi Jasssssminnnnn
- Bugscope TeamAnd this is a totally different looking proboscis on a mosquito
- Bugscope Teamokay this is the outside of the proboscis of the skeeter
- Bugscope Teammosquitos are covered in scales, as are butterflies and moths
- Bugscope Teamyou can see several of them here
- Bugscope Teamtake the mag down, Dude
- Bugscope Teamso you have some, like, perspective
- Bugscope TeamEmily, Kaitlyn, Liz, Nick, Casey, Jazz feel free to ask questions if you want
- Bugscope Teamand Melissa, and Amy
- 5:38 pm
- Bugscope TeamScales frequently have the finest micro-structure of any insect body parts, sometimes showing features on the scale of nanometers, or billionths of a meter
- Bugscope Teamlet us know if you are having trouble drivin', Jeff
- GuestWhat are the long flagella like things?
Bugscope Teamthose are scales!
Bugscope Teamthe things that are kind of like leaves are scales
Bugscope TeamThose are just a variety of setae ("hairs"). There are often several different types all in one area. Some are mechano-sensory (they feel touch), some chemosensory (chemical sensing/taste/smell)
- Bugscope Teamlike, nothing has changed for awhile
- GuestHow long are the scales?
Bugscope TeamYou can see the scale-bar in the lower-left corner of the image is showing about 10 microns, which is equivalent to about one-fifth the width of a human hair
- Bugscope TeamMosquitoes, silverfish, moths, butterflies, and very few beetles and weevils have scales
- Bugscope Teamokay I am driving if you are not....
- Guesthe is teaching
- Guestso the long ones are scales...what are the short hair-like structures used for?
Bugscope Teamthe short ones are often chemoreceptors
Bugscope TeamThe oar-shaped ones are the scales.
- Bugscope Teamokay cool, AnnaMarie I gave you control
- TeacherI am talking to the class.
- GuestIs the whole Mosquito covered in scales?
Bugscope TeamYes, most of their body has scales. The only part I can think of that doesn't, offhand, are the eyes
- Guestoh cool! thanks!
- Bugscope Teamokay think about it like this. if you had a classroom full of kids and had the opportunity to drive a $600,000 scanning electron microscope, would now be a good time to do a lecture?
- Guestsure why not
- Guestthe controls have been taken away from jeff
Bugscope TeamAnnaMarie has them
- 5:44 pm
- Guestgive them to emily!
- Bugscope TeamEmily has control.
- Bugscope TeamSorry, scott had just given them to annamarie so she could continue driving
- Bugscope TeamActually Jeff if you want to drive let us know.
- Guesti am very bad at it but emily will be better
- Bugscope Teamnice
- Bugscope TeamEmily you can choose from any of the presets as well.
- GuestAre some of the scales falling off?
Bugscope TeamYep, the moth scales had be released, which comes in handle when you get stuck in a spider web: release some scales and fly away, to fly in a web another day...
- Guestdo mosquitos bite or sting?
- Bugscope TeamAs scott was saying, all of the chat and images are archived in a transcript format on our website automatically, so when you're planning a Bugscope lesson you can focus on driving around as much as possible during your hour, then review the chat and images as an activity afterwords
- Bugscope TeamHere's another thing to think about: suppose you were wearing a suit of armor all of the time. How would you feel things that were touching you -- touching the suit of armor?
- GuestDo you mean that the scales are like a suit of armor?
Bugscope Teamwell, i think he meant that the exoskeleton is like a suit of armour. the exoskeleton can't feel anything, it has no nerves in it
- Bugscope TeamIf you had long sensory hairs projecting through that armor you could feel what you were next to, and if they were thermosensory you could sense heat, and if they were chemosensory you would smell with them
- Guestyea they are, that's why they need the chemoreceptors, right?
- Guestmichael would like the controls now :)
- Guestjk, give to casey
- Bugscope Teaminsects have an exoskeleton, as Alex said -- they have their skeleton on the outside
- Bugscope Teamso many of the hairs we see, which we call 'setae,' are sensory
- Bugscope TeamCool!
- 5:49 pm
- Bugscope Teamthis is a large beetle
- Guesthe looks mean!
- Bugscope Teamthe head
- Guestis this still a mosquito?
Bugscope Teamthis is a beetle
- Bugscope Teamcool face
- Guestno jazzzzzzzzzzzz
- Bugscope Teamthis is the head, and you can see the proximal parts of the antennae, the jaws, and the palps, as well as the eyes
- Bugscope Teamtwo large compound eyes on the top/side of the head, antennas next to the eyes, and mandibles beside the mouth
- Guestdoes this guy have a brain?
- Bugscope Teamit takes a little while to get driving down. Jeff is a natural.
- Bugscope Teamyou can see the curve of the compound eye
- Bugscope Teamthe ommatidia on the compound eye are streamlined into the surface
- Bugscope Teamyep
- Bugscope Teamif you had compound eyes you would likely have better peripheral vision, and you would also have the ability to sense motion -- changes in the visual field -- very quickly. good if you are a bug
- Bugscope Teamthis is a true bug -- Hemiptera
- Bugscope Teamnot all insects are bugs, but all bugs are insects
- Bugscope Teamthe lens's in the compound eye are fixed, they can't move around like our lens's can. so they have hundreds of fixed lens's pointed in a curved area, that gives them peripheral views
- Bugscope Teamwhen we do Bugscope sessions we often have entomologists on board to help
- Bugscope Teamlike, real entomologists
- Bugscope TeamHemiptera all have piercing/sucking mouthparts, and their elytra are a little different from beetles, for example
- 5:54 pm
- Bugscope Teama true bug is a hemipteran
- GuestSend the controls to Jazz
- Bugscope TeamJaws has control now.
- Bugscope Teamclick again to stop jazz
- Bugscope Teamtrue bugs have a proboscis they use to stab into insects are plants
Bugscope Teamthat's how you can usually tell if an insect is a true bug
- Guestok so whats a hemipteran?
Bugscope TeamHemiptera are the so-called true bugs
- Bugscope Teamjazz, click on the image again, that'll stop it moving
- Bugscope TeamSorry guys -- temporary technical difficulty here; we're stuck moving along
- Bugscope Teamhemi ptera means 'half wing,' and is intended to describe how their wings are connected, or not, to the elytra, which is the hard shell on the back
- Guestis an ant a true bug?
Bugscope Teamno- true bugs look more like a beetle with a tube for a mouthpart
- Bugscope Teamokay, we are fixing
- Bugscope TeamOK, we should be back in action. Jumping back to a preset now
- Bugscope Teamokay, it should be fixed
- Bugscope Teamjazz has control again
- Bugscope Teammake sure, when using click to drive, click once to start moving, then click again to stop.
- Bugscope Teambut you guys are doing great, keep it up
- Bugscope TeamOccassionally the click-to-drive gets stuck during the movement part
- GuestWhat is this a picture of?
- TeacherWhat is this a picture of
- Bugscope TeamYou're seeing the facets of a compound eye
- Bugscope Teamcalled ommatidia
- Bugscope Teamants are hymenoptera like bees and wasps
- 5:59 pm
- Guestabt how many facets are there on a beetle eye?
Bugscope TeamIt depends on what kind of beetle, but I'll put out a ballpark of tens to hundreds
Bugscope TeamThe number of facets in a compound eye, through my experience, is closely correlated with how dependent they are on their vision. Flying insects have much higher density ommatidia than ants which live underground in the dark
- Guestand i can't click anything....it says, plz wait on the screen, Looks different from everyone elses screen too
Bugscope Teamsorry, hit reload (F5) and it should get you reset
- GuestIf a part of the compound eye is injured and unable to function do the other parts continue to work?
Bugscope Teamyes they are sort of redundant that way
- Bugscope Teamsome true bugs use their piercing mouthparts to suck up plant juices, and some use them to pierce other insects
- Bugscope Teamjazz, can you refresh your browser, F5, then try again
- Bugscope Teamcollateral damage from the issue a moment ago
- Bugscope Teamclick again to stop moving
- Guestok sooo its not working. maybe its my computer...switch controls to someone else
- Bugscope Teamnote that you are not actually seeing 'pictures' -- you are seeing live images on the scanning electron microscope
- Bugscope TeamJazz, if you click in the image again it will stop driving.
- Bugscope TeamCarly has control now.
- GuestGO BLONDIE GO!
- Bugscope TeamOk, Scott's taken us to a preset here, Go ahead and navigate where-ever you like!
- Bugscope Teamand I just took the 'scope to a place to start from
- Bugscope Teamthis is one of the legs of the grasshopper
- Bugscope TeamHere you're seeing the forearm and of a cricket reaching up into the air
- Bugscope Teamyou can see the claws, and you can see that the tarsi further down are modified to form something like the sole of a shoe.
- Guestdo grasshoppers have compound eyes as well?
Bugscope Teamyes they do
- Bugscope Teamthe ommatidia are kind of flat on a grasshopper compound eye
- 6:04 pm
- GuestWhat is the average lifespan of a grasshopper?
Bugscope Teamgrasshoppers live as fertilized eggs for maybe 10 months. they are adults for about 30 days, and before that they are nymphs for awhile -- 20 to 50 days is what I read. so about a year
- Bugscope Teambut the individual facets of the eye, like in praying mantises and some other insects, are streamlined into the shape of the eye -- they're hard to make out
- TeacherScott can I please have control again. All others seem to be freezing up.
Bugscope Teamyou have control
- Bugscope Teamwhereas on a fly compound eye, the ommatidia are very curved in shape, with a hexagonal perimeter
- Bugscope Teamjeff, you've got control
- TeacherCan I get presets.
- Bugscope TeamThis is an odd structure near where the thorax and abdomen join on a small fly
- Bugscope Teamsure, go ahead and click on a preset, it should take you there
- TeacherI want to start at 1 and go to 14
- Bugscope TeamThis is preset 1
- Bugscope TeamThis is the head of the stink bug, as viewed from below
- Bugscope TeamWe can zoom out here and see this in context
- Bugscope Teamthese are odd setae
- Guestwhat;'s a stink bug? I've never heard of that before. does it perhaps go by some other name as well?
Bugscope Teamthey are also called shield bugs i think
- Bugscope Teamand here's the grasshopper claw
- Bugscope Teamcool, this is a palp
- Bugscope Teamstink bugs are also Hemiptera. they are usually plant pests, I think. if you bother them they will squeeze out a drop or two of foul-smelling liquid that makes you want to leave them alone
- 6:09 pm
- Bugscope TeamThis is a cool one!
- Bugscope Teamthey are shield shaped
- Bugscope TeamSpikey
- Bugscope TeamAnd this is an isopod leg
- Bugscope Teamyeah, these are some kind of microsetae i think.
- Bugscope Teamsome people use 'shield bugs' and 'stink bugs' as synonyms, but I am not sure that is correct
- Bugscope Teamnow this is wendy's salt. we think they add some compound to it that gives it an odd structre
- Bugscope Teamstructure
- Bugscope Teamthese are odd things on the fly abdomen, i'm not sure what they are
- Bugscope Teamah, this is a proboscis
- Bugscope Teamthis is cool
- Bugscope Teama moth proboscis
- Bugscope Teamelephants also have a proboscis, their trunks. that is the largest proboscis in the world
- Bugscope TeamLooks like soft-serve icecream
- Bugscope Teammoths and butterflies with coiled probosces like these fill them with hemolymph to get them to extend out
- 6:14 pm
- Bugscope TeamWas interesting to see the charging effect there
- Bugscope Teamwe are beaming electrons at these samples in a vacuum chamber, and the samples are coated with gold-palladium to make them conductive
- Bugscope TeamIf you zoom out you can see the ball and socket style join for the leg there
- Bugscope Teambut insects, in particular, are hard to make completely conductive because they have so many fine features that do not conduct electrons down the bodyny fine fea
- Guestlooks like it wants to hug
Bugscope Teamheh, yeah, roly poly's are cool
Bugscope TeamI nominate you
- GuestTHANK YOU!
- 6:19 pm
- Guestthank you!
- GuestThank you!!
- Bugscope Teamthanks for logging in today!!
- GuestThank you!!
- Guestthanks for showing us this cool stuff!
- Bugscope TeamYou're welcome guys! Hope to see you back on again
- Guestthank youuu
- Guestthank you! ^_^
- Guestthank you so much! :)
- Bugscope TeamThank you for connecting with us today.
- Guestthanks, this was really cool
- Guestthanks, this was great
- Bugscope Teamjeff, make sure to check your member page after the session, http://bugscope.beckman.illinois.edu/members/2010-008, it saves all the chat and images from this session
- Bugscope TeamWe have done this for 11 years now, somewhere around 500 sessions.
- Bugscope Teamyou all did great work
- Bugscope Teamit was fun having you in bugscope
- Bugscope TeamJeff you did a good job.
- TeacherThank you very much I will email you tomorrow. Once again thank you.
- Bugscope Teamthanks jeff
- Bugscope Teamlater!
- 6:25 pm
- Bugscope Teamgood bye students
