- 12:08 pm
- TeacherThe students will be here at 1:30 eastern time. Which insect is this?
- 12:13 pm
- Bugscope Teamhello sorry we were working on presets
- Bugscope Teamwe are on the praying mantis
- Bugscope Teamif you want, you can practice driving around
- Bugscope TeamHello! Welcome to Bugscope!
- Bugscope TeamMrs Vignale you may drive if you like.
- Bugscope Teamthe controls are to the right of the image
- Bugscope Teamand the presets, which will take you to the areas that are thumbnailed, are to the right of this chat box
- Bugscope Teamthis is one of the spikes on the praying mantis's arm
- Bugscope Teamseen from the top
- 12:19 pm
- Teacherneat! Where did the praying mantis come from?
- Bugscope Teamit was a leftover insect from another school
- Bugscope Teamfrom arizona
- Bugscope TeamMrs V be sure to try driving if you haven't had a chance. Have we worked with you before?
- TeacherWhen the students arrive, should I choose from the presets or wait for you to change the image. This is my first time. I am trying to figure out how to drive.
- 12:24 pm
- Bugscope TeamYou can drive yourself -- you don't need us but we are here to help.
- Bugscope Teamon the right you will see the controls. you can either choosse a preset to get to another insect and/or you can drive manually by either click to drive or click to center
- Bugscope Teamone thing that is super easy is to change the mag, on the upper left of the screen.
- Bugscope Teamand there is one of the presets with the pollen all over the place -- this is part of the abdomen of the bumblebee
- Bugscope Teamwhen we get close the electrons may make the sample charge up and give us an overly bright image
- Bugscope Teamlots of pollen looks pretty much like this -- like ragweed pollen
- Bugscope Teamit's cool you are really driving a scanning electron microscope from your classroom
- Bugscope Teamlike a $600,000 vehicle
- Teacherawesome!
- Bugscope Teamif you go to lower and lower magnifications you can see where you are on the bumblebee
- Bugscope Teamsometimes we make presets so that you can see something up way close and when you go to a low mag you may have a surprise at where you find yourself
- 12:33 pm
- Bugscope Teamhello money and mini muffin
- Bugscope TeamHello Money, and Mini muffin!
- Teacherok the students are here...
- Bugscope Teamhi Bob and Fred
- Studenthi
- Bugscope Teamand Josh and Leela
- Bugscope TeamHello JR!
- Bugscope Teammrs vignale, the students can also have control of the microscope to drive around if you wanted
- Bugscope TeamMrs V feel free to drive, change presets, change mag, or as Cate says we can confer control to the students if you would like
- Bugscope Teamhello yoyo em
- Bugscope Teamif you have any trouble please let us know
- Teachershould we have just one driver at a time?
- Bugscope Teamyes only one person can drive at a time
- Bugscope Teamthere is no way to have more than one driver, it is just a safety precaution
- Bugscope Teamwe can confer control to whomever you would like
- Bugscope Teamso like Bob and Fred?
- Teacherthe students don
- Teacherthe students don't have a driver and neither do i now
- Bugscope TeamBob and Fred have a driver now
- Bugscope Teamif they would like to try
- 12:38 pm
- Bugscope Teamthis is part of the abdomen of the bumblebee, way high magnified
- Bugscope Teamnice --
- Bugscope Team now you can see where we were
- Bugscope Teamthis is the belly of the bee
- Bugscope Teamthe head is to the north
- Bugscope Teamto the top of where we are looking now
- Bugscope Teamif you would like to see another insect you can choose from among the presets on the right side of this chat box
- Bugscope Teamwe may be at the lowest possible magnification for this sample
- Bugscope Teamif you would like you can try click to center or click to drive
- Bugscope Teamclick to drive lets you go in a chosen direction when you click on the screen
- Bugscope Teamthis is the head
- Bugscope Teamyou can see the eyes on either side, and you can see the jaws
- Bugscope Teamthe antennae would be in that thicket of 'hair' in the middle of the head
- 12:43 pm
- Bugscope Teambut you can see that they are broken off
- Teachercan we add another driver?
- Bugscope Teamsure!
- Bugscope Teamlet us know who
- Teacherjosh and Leela
Bugscope Teamthey have control
- Bugscope Teamyou would like to drive
- Bugscope Teamgo it
- Bugscope Teamgot it
- Bugscope Teamsometimes it takes a little while to figure it out
- Bugscope Teamand sometimes it takes some time for a command to get to the 'scope and return the results to you
- Bugscope TeamJosh and Leela try one of the presets if you would like
- Bugscope Teamhey cool!
- Bugscope Teamthis is the butterfly proboscis
- Bugscope Teamthe little circles are sensory area for tasting
- Studentwhat are the holes
Bugscope Teamthose are sensory areas for tasting things
- Guestwhy is it so bumpy
- Studentwhat is this
- Bugscope Teamit is bumpy so it will stick to the inside of the flower
- Guestwho is on the air
- Bugscope Teamthis is the proboscis of a butterfly
- StudentWhy is it in a circle shape
- Bugscope TeamLivvie you mean who are we working with today?
- Bugscope Teamit is a circle shape because it is naturally coiled up when it is not being used
- StudentHI
- Teacherwhy is it swirly?
- 12:48 pm
- Studentwhat are the lines for
- Bugscope Teamit's like one of those new years party favors that you blow into and it unfurls and makes a sound.
- Bugscope Teamwhen the butterfly wants to put its proboscis into a flower it makes it straighten out
- Guestwhat are the spots on the picture
- Bugscope Teamyes like Cate says
- Studentwhat is the big bump at the top
Bugscope Teamthat is some juju-- debris like dirt or dust
- Bugscope Teamexcept this doesnt make a sound everything else is very similar.
- Bugscope Teamthere is some dirt on the proboscis
- Bugscope Teamwe think the little pores we see are chemosensory -- then butterfly can smell with them
- Bugscope Teamthe butterfly, that is
- Bugscope Teambe sure to try another preset
- Guestwhat is that the long pointy thing in the upper right corner?
- Bugscope Teamif you would like
- Bugscope Teamthat is a spine on the edge of the proboscis
- Teacherit looks like snakeskin
- Guestwhat are the notebook swerl things
- Bugscope Teamif you go to a lower mag you may see more
- Teachercan mini muffin drive now?
- Bugscope TeamMini muffin has it
- GuestHow long is the proboscis?
- Studentwhat are the lines for on the eadge of the probscis
- Bugscope Teamthe notebook swirl things are almost what you would expect from something that needs to be able to coil up
- 12:53 pm
- Bugscope Teamit is kind of like a vacuum cleaner hose
- Guestwhy dose it look so smoth?
- Bugscope Teamwhen you click to drive, you have to click again to stop
- Guestwhat is this
- Bugscope Teamthis is part of the microscope stage
- Bugscope Teamnow we are the praying mantis
- Guestwhat are those lines
- Guestcool
- Bugscope Teamgood driving
- Bugscope Teamthe eye!
- Studentwhat's the hair
Bugscope Teamthose are scales from another insect like a moth or butterfly
- Guestwhy are the eyes so big?
- Studentwhat are the circles that look like craters
- Bugscope Teamso they can see very well when they capture other bugs
- Bugscope Teamthose are the ommatidia
- Guestwhat is the bump
- Bugscope Teamthe individual facets of the eye
- Bugscope Teamthere are also scales on the surface of the eye
- Bugscope Teamyou can see them now
- Studentwhat are the "footprints"
- Bugscope Teamthose are the scales
- Studenthow do we make the new preset show
- 12:58 pm
- Bugscope Teamthey are from a moth or butterfly
- Bugscope Teamtry to focus
- Bugscope TeamMrs V you have control now
- TeacherI have another class coming in now
- Bugscope Teamcool!
- 1:04 pm
- Bugscope Teamthis is another one of those 'footprints'
- Bugscope Teamthis is part of the butterfly wing
- Bugscope Teamwhen you rub a butterfly or moth, gently, and powder comes off of it, the scales are the 'powder'
- Bugscope Teamwe could not put the whole butterfly in the microscope chamber
- Bugscope Teamsee the ribs?
- Bugscope Teamand the pattern between them?
- Bugscope Teamthis is what makes the scale strong and light
- StudentThe scales are amazing
- Bugscope Teamthe micron bar, to the left on the screen, gives you an idea how high the magnification is
- Bugscope Teamwhen it says 11 um, for example, that is about 5 bacteria long
- Teacherwhat are the ridges for on the scale
- Bugscope Teamthe ridges give the scale rigidity, like ruffles on potato chips
- Bugscope Teamthey also reflect light in interference colors
- Bugscope Teamthe scales have pigment in them that gives us true colors
- 1:09 pm
- Bugscope Teambut the scales may also show us other 'structural' colors
- Bugscope Teamthis is the claw, one of the claws, of the bumblebee
- StudentWhat is the foamy stuff on the butterfly we saw?
- Bugscope Teamit has lots of pollen on it
- Studentwhat are the little hair things?
Bugscope Teamthey are just that-- hairs, but on insects we call them setae (pronounced see-tee)
- Bugscope Teamthe foamy stuff may have been the silver paint we put on the stub to get the wing to stick down
- Guestwhat are the balls?
- Bugscope Teamsee the little pollen grains?
- Bugscope Teamthat is what the spikey balls are
- Guestwhy are there hairs on the spikes
- Bugscope Teamyou mean on the pollen grains?
- Bugscope Teamthe setae are there so that the insect can sense what is around them using touch, taste/smell, etc
- Studentyes
- Bugscope Teamthe spikes on the pollen grains ensure that they stick to things
- Guestcool
- Studentaswome
- Bugscope Teamthey're like nettles
- Guestits cool
- Studentyah
- Bugscope Teamthis is on the abdomen of the bee
- Teachercan dave norm drive now?
- Bugscope TeamMrs V you are doing a great job driving
- Guestwhat is in the backround
- Bugscope TeamDavenorm dropped off for a sec, looks like
- Bugscope Teamthe background is the folds of the abdomen of the bee
- Bugscope Teamthe pollen are clinging to the bee setae, which looks like bare trees kind of
- Guestwhat are the big hairs?
- Bugscope Teamthat is the border between segments of the abdomen
- 1:14 pm
- Studentwhy does it look like its stuck in mud?
- Studentwhats that?
- Bugscope TeamMrs V can we give someone else control?
- Teacherare dave norm able to ddrive now?
- Bugscope TeamThere may be some dirt there,
- Studentcan nate and spencer drive
- Bugscope TeamDavenorm are disconnected and may need to be helped back on
- Bugscope Teamin the meantime nate and spencer have it
- Bugscope Teamdavenorm seems to be inactive or disconnected because they are grayed out
- Bugscope Teamthe grass like things are setae on the bee's abdomen
- Bugscope Teamnow you can see where we were
- Guestthats cool
- Bugscope Teamsee the segments of the abdomen?
- Bugscope Teamthe head is to the top
- Bugscope Teamif you want to drive up there
- Bugscope Teamor click on another preset
- Bugscope Teamnate and spencer you have control
- Bugscope Teamstill
- Guestare the hairy things polin?
- Bugscope TeamHa Normdave you have control now
- Bugscope Teamthe hairy small round balls are pollen
- Bugscope Teamthere is a lot of it on this bee
- Bugscope Teamyay!
- Bugscope Teamthis is the head of the rolypoly you sent
- Bugscope Teamthis is the underside of the jaw
- 1:19 pm
- StudentWhat are the hairs for
- Bugscope Teamthis is plate that moves when the rolypoly eats
- Bugscope Teamthe hairs help it sense when things are touching it
- Bugscope Teamthe cuticle is very thick, like armoer
- Bugscope Teamarmor
- Studentwhat are the claws?
Bugscope Teamclaws are used to grasp onto food
- Bugscope Teamor other things
- Bugscope Teamthose things that looked like submarine sandwiches are the antennae
- Bugscope Teamthe hairs let the rolypoly feel what it is touching
- Studentare the hairs used for feeling?
Bugscope Teamyes or smelling or tasting depending on where they are. some hairs can feel vibrations like spider hairs will look different
- Teacherwhat are the claws used for?
- Bugscope Teamthey don't have nerves in their skin -- because they don't have skin -- the cuticle, or chitin, is like a coat of armor
- Studentwhat are the holes
- Teacherplease let mrs v drive now
- Bugscope Teamhey I was wrong! I am sorry -- this is a Japanese beetle
- Bugscope TeamMrs V you have it
- Bugscope Teamthis is the butterfly proboscis
- Bugscope Teamall coiled up
- Studentwhat does the antanae look like?
- Bugscope Teambutterflies are very neat and put their tongues away when they are done with them
- Bugscope Teamit is spiral so it does not get in the way when the butterfly flies
- Guestare those scales?
- Bugscope Teamthey are platey portions of the chitin
- 1:24 pm
- Bugscope Teamlike scales, aren't they?
- StudentCan we have the controls next? Pretty please!?
- Studentwhy does it look like snake skin?
- Bugscope Teamthey allow the proboscis to coil and uncoil
- StudentWhat is the chitin?
- Bugscope Teamit looks like snake skin because it functions similarly
- Bugscope Teamit needs to be able to coil and uncoil
- Teacherwhat are the eye spots for?
- Bugscope Teamchitin is what the exoskeleton is made of
- Bugscope Teamit is like what our fingernails are composed of
- Bugscope Teamor shrimp shells, for example
- Bugscope Teamthe spots are where we see what we think are chemoreceptots
- Bugscope Teamchemoreceptors
- Bugscope Teamsorry
- Bugscope Teamfor tasting/smelling
- StudentHow does it make the spiral?
- Guestwhat are the
- Bugscope Teamthat is how the butterfly can smell chemicals in the air, or as Cate says -- tasting
- Studentwhy does it look like it is bubles
- StudentButterflies have exoskelatons?
- Bugscope Teamyes they have their skeleton on the outside like other insects
- Bugscope Teamits like a new years party favor that you blow into and it unfurls and makes a sound
- Guestwhat are the scals
- Bugscope Teamso like Cate says when the butterfly wants to use its proboscis it pushed hemolymph into it and makes it extend
- Bugscope Teampushes
- StudentWhat are those line things?
- Guestwhat is the corn like thing
- Bugscope Teamthe things that look like little cobras are tenent setae
- 1:30 pm
- Bugscope Teamthey are setae that help beetles and flies, for example, stick to vertical surfaces
- Studentwhat are the hairs
- StudentHow does it do that?
- Teacherwhat is a tenent setae?
Bugscope Teamthey allow the insect to walk on walls
- Studentwhy does it look like a flower?
- Bugscope Teamthose are tenent (like tener, in Spanish) setae
- Bugscope Teamit means that the setae are able to hold onto things like walls
- Guestwhat is that corn like object
- Bugscope TeamOh the corn like object was a scale
- Bugscope Teamis a scale
- Bugscope Teamfrom another insect
- Guestwhat is the hair like thing
- Bugscope Teamthis is the praying mantis head
- Bugscope Teampop sorry I missed it
- Bugscope Teampraying mantises kind of look like aliens under the microscope
- Bugscope Teamthis is the top of the head
- Bugscope Teamyou can focus it better
- Bugscope Teamand this is the face
- Studentthe thing on the claws looks like corn on the cob and I just want to eat it. "YUMM"
- StudentDo praying mantises have compound eyes?
Bugscope Teamyes they do, 2 big ones at that
- Bugscope Teambubbles in the tape
- StudentI see lots of hairs.
- Bugscope Teamyou can see the edge of the world now
- Bugscope Teamthis world is flat
- 1:35 pm
- Bugscope Teamtry focusing
- StudentWhat are those bubles?
- Bugscope Teamah this is part of the compound eye of the mosquito
- Bugscope Teamthe bubbles are the individual ommatidia
- Bugscope Teamthey are a little deflated so they look more like bean bags
- GuestWhy do the eyes look big
- Studentwhat are the blobs
Bugscope Teamthey are the individual facets of the mosquito compound eye
- Bugscope Teamyes when they are alive the eyes are inflated
- Bugscope Teamyes those are compound eyes
- Bugscope Teamah this is a true bug
- Bugscope Teamhemiptera
- StudentWhat is that?
- Bugscope Teamyou can see that it has a piercing proboscis
- Bugscope Teamwhich we are looking at now
- Teacherwhat kind of bug
- Bugscope Teamthis is the mid portion of the proboscis
- Guestwhat kind of bug is this?
- StudentThose look like carrots
- Bugscope Teamsome type of stinkbug i think
- Bugscope Teamthis is the same kind of bug as a stinkbug or shieldbug
- Bugscope TeamCate beat me to it as usual
- Bugscope Teamwhen the bug wants to eat it pierces its food with this strawlike proboscis
- Teacherhow much time do we have left?
- StudentThats is a dirty stink bug
- Bugscope Teamwe can run a little longer if you would like
- Bugscope Teamwe built some time onto the back of the session
- StudentWhat are the tubes on it?
- 1:40 pm
- Bugscope Teamthat sounds good
- Bugscope Team2 our time, 3 your time
- GuestWhat are those stick like things?
- Teacherok great
- Bugscope Teamall of the images you get are saved to your school's database
- Bugscope Teamthe things that looks like little sticks I think are more setae
- Studentwhat are those carrott things?
- Bugscope Teamthere may also be some wax among all of the juju we see that makes the stinkbug look dirty
- Bugscope Teamthe carrotllike things in the middle are parts of the proboscis
- Bugscope Teamcarrotlike
- Bugscope Teamthis is kind of cool
- Bugscope Teamsquare ommatidia
- StudentIs that part of the body?
- Bugscope Teamon the bee head I think
- Guestwhat are the sqares
- StudentWhat are the squares?
- Bugscope Teamthe individual facets of the eye
- Guestwhat are the bumps?
- Bugscope Teamif you had a compound eye you would be able to register movement very quickly
- StudentIs ommatidia compound eyes?
Bugscope Teamommatidia are the individual facets of a compound eye--the bumps
- Bugscope Teamthe dark spot was were the electron beam had sat for a long time
- Bugscope Teamas you can see, it's just a head. it feel off en route to us
- 1:45 pm
- Bugscope Teamthe simple eyes are the three smaller bumps
- Bugscope Teamso this wasp has five eyes
- Bugscope Teamnear the top center
- Guestdid the head fall off?
Bugscope Teamyes, sorry. sometimes when insects are really dry, limbs just fall off
- Bugscope Teamyeah sorry
- Bugscope Teamsometimes that happens
- Bugscope Teamthis is cool
- Bugscope Teamthe eye is streamlined right into the shape of the head
- Bugscope Teammakes it easy to fly quickly
- Guestwhy does it look like a bear tummy
- Bugscope Teamoh
- Bugscope Teamthis is where the antennae were
- Bugscope Teamhey there is a pollen grain
- Guestwhy is it fuzzy?
- Bugscope Teamyou can find stuff we did not see before
- Bugscope Teamoh I know the fine setae on the surface of the hed
- Bugscope Teamhead
- Studentwhy does the eye have bumps on it ?
- Teacherwhat is the cave thing we are going into?
- StudentWhat is the cave
- Bugscope Teamthat is called the 'vestiture'
- Bugscope Teamthis is the inside of the antennal tube
- Guestwhy is it creepy
- Bugscope Teamthe fine hair on the head is called vestiture
- Bugscope Teamit is creepy because we are looking into the head
- Bugscope Teamlike a little cavern
- Bugscope Teamah cool
- Bugscope Teamnow this is a mosquito stylet
- 1:50 pm
- Bugscope Teamthey have more than one of these
- Bugscope Teamthat form the facsicle
- Guestfgihjrtipjrhigye4yt4we8rfe
- Bugscope Teamthe facsicle, as Cate says, is the part tht pierces your skin
- Bugscope Teamwhen the moqsuito bites you
- StudentWhy does that have blades on it?
- Bugscope Teamit is like a little saw
- Bugscope Teamso it can cut its way into your skin
- Teacherdoes that sting ?
- Bugscope Teamstingers are like this too
- Bugscope Teamit is very small but you can feel it
- Bugscope Teamyou can see that it is tiny
- Bugscope Team20 microns on the scale we see is 0.02 millimetes
- Bugscope Teamthey inject an anticoagulant into you so that your blood will keep flowing, and that is the stuff that makes you itch
- Bugscope Teammillimeters
- Studenthow does it get in your skin
- Bugscope Teamthis is a view of jaws that look like blades
- Bugscope Teamthis is an insect that Annie, our entomologist, brought us
- Guestwhy does it have spikes
- Bugscope Teamthe facsicle gets into your skin by cutting its way in
- Bugscope Teamthe little spikes on the jaws are probably chemosensors
- Teachercan we learn about this
- Studentwhat are the hairs for?
- Bugscope Teamthe fly can taste what it is biting into
- 1:55 pm
- Bugscope Teamthe hairs, most of them, function to help the fly sense what it is touching
- Bugscope Teambecause they can't feel through their exoskeleton
- Bugscope Teamwhich is thick
- StudentWhat's inside the jaw?
- Guest-
- Bugscope Teamsome of the tiny setae are also chemosensory or thermosensory
- Bugscope Teaminside is the way to the mouth
- Bugscope Teamoften mouths are confusing to us
- StudentIs that a claw?
- Bugscope Teamthere are often palps around the mouth that are used to move food around or to taste/smell food
- Bugscope Teamthey work sideways compared to ours, and they have little helper limbs called palps that manipulate and taste their food
- Bugscope Teamd'oh
- StudentAre there hairs inside the jaw
- Bugscope Teamthat is a jaw
- Bugscope Teamit kind of does look like a giant claw but they are mouthparts
- Bugscope Teamthese are hamuli found on a wasp
- Guestwhy is it so hairy
- Bugscope Teamwasps and bees have four wings
- StudentWhat are those hoops?
- Bugscope Teamthey act as hooks to keep together the 2 sets of wings the wasp has so it can act like 1 big pair of wings
- StudentWhy is it a spiral?
- Guestwhat are the spikes
- Teacherwhat is is a hamuli?
Bugscope Teamthey are curved hooks that are found on one set of wings (wasps have 2 sets for a total of 4 wings) and they hook onto the other set of wings to make it like 1 big pair of wings when they fly
- Bugscope Teamit looks like it is spiral but it is a series of hooks
- Teacherwhat are the hooks used for?
- 2:00 pm
- Bugscope Teamthey look spiral but they are individual curved hooks
- Teacherthank you and good bye!
- Bugscope TeamThank You!
- Bugscope Teamthank you for all your questions. all your chat and images from today can be found at your member page http://bugscope.beckman.uiuc.edu/members/2008-073/
