• 1:12 pm
• Bugscope Teamwe took out the sample and are going to put a wasp on it and put it in the chamber again. it should be pumped soon and we can make the presets
• 1:26 pm

• 1:31 pm

• 1:36 pm

• 1:41 pm

• Bugscope Teamall right we are ready on our end
• Bugscope TeamCol Chas!
• Bugscope TeamThe problem we had resolved itself, in a way
• Teacherhey! whats up were here!
• Bugscope Teamyay!
• Bugscope Teamwe don't know what a couple of these guys are
• 1:47 pm
• Teacherhow do i make this full screen
• Bugscope TeamF5
• Bugscope Teamok ms. clark, so you know how it works. Two of your samples are on here-- the potter wasp and the housefly
• Bugscope TeamFrom a Windows PC you should be able to hit F11
• Bugscope TeamF11
• Bugscope TeamF5 refreshes I think
• Bugscope Teamyeah sorry wasn't thinkin'
• Teacheris this the house fly?
• Bugscope Teamthis is a borer of some sort
• Bugscope Teamperhaps

• Bugscope Teamno this is some sort of borer that was brought in to us
• Bugscope Teamthe housefly can be found at preset 4

• Bugscope Teamcompound eye
• Bugscope Teamif you have compound eyes you have a high refresh rate and can see changes in your visual field very quickly
• Teacherwhat are the hairs coming out of the eye
  Bugscope Teamthose are hairs, which when we find them on insects are called setae or for one hair- seta
• Bugscope Teamkeeps you from getting smacked
• Teacherhahahahahahaha
• Bugscope Teamsee-tee

• Bugscope Teamin fruit flies the setae between the ommatidia are used to gauge windspeed
• Bugscope Teamommatidia are the facets of the eye

• 1:52 pm
• Bugscope Teamnice mouthparts
• Teacherhow does the mouth work?
• Bugscope Teamwe were thinking this was some kind of borer, and the middle things we see now look like powerful jaws
• Bugscope Teambut we are not sure what this is
• Bugscope Teamif you go a little closer maybe we can make out some more of the structure

• Bugscope Teamhard to tell -- we will have to ask Annie what that was
• Teacherwhat is this?

• Bugscope Teamthis is another insect that was brought in with the "borer". It is another mystery bug
• Bugscope Teamwell -- sorry but this was the other mystery bug -- a beetle

• Bugscope Teamit has a pretty big muscley-looking head

• Bugscope Teamyeah 'cause we don't think it is particularly smart

• Bugscope Teamwhat we see is one of the jaws, and the thing that looks like a bat is one of the palps
• Teacherhow does the mouth work?
• 1:57 pm
• Bugscope Teampalps are mouthparts that taste and manipulate food
• Bugscope Teamin this case the jaws open and close like little gate hinges

• Teacheris the mouth broken?
• Bugscope Teammaybe a little
• Bugscope Teamit looks like the top part is chipped
• Teacherhow much was this microscope/

• Bugscope Teamabout $600,000
• Bugscope Teamand that was about 10 years ago

• Bugscope Teamit is very nice

• Teacherit better be nice if it costs that much

• Bugscope Teamit can do a lot of things we don't see now
• Bugscope Teamlike elemental analysis
• Teacheris that the eye or the antennae?
  Bugscope Teamit is both. there is a section of the antenna that is partially broken and the compound eye is right behind it
• Bugscope Teamthat is the antenna

• Bugscope Teamwith the eye behind it
• Teacherwhy is the antannae infrnt of the eye?

• Bugscope Teammaybe because the antenna is more important to the insect

• Bugscope Teamyeah it wouldn't be able to see to well in front with something blocking the way one would think
• Teacherwhat do the hairs do?
• 2:02 pm
• Bugscope Teamthe hairs are often sensory

• Bugscope Teamsome are chemo- and some are mechanosensory

• Bugscope Teamowlfly larva

• Bugscope Teamthis is one of the little claws
• Teachercan we break it?

• Bugscope Teamowlflies are predatory

• Bugscope Teambreak the microscope?
• Bugscope Teamno

• Bugscope Teamwe set it up so that there is little that can be done from a distance to cause problems

• Bugscope Teamthe larvae are predatory too. they are related to antlions

• Bugscope Teamthey are kind of mean, like dragonflies
• Teacherwhat do all the hairs do?
• Teacherand why are they there

• 2:07 pm
• Bugscope Teamhairs generally have a sensory purpose like cat or rat whiskers

• Bugscope Teamit could serve the purpose of keeping away bigger insects (like why caterpillars are so hairy), but it could also be like trigger hairs that will make the jaws snap on the insect that is near it

• Bugscope Teamso they would not be able to feel their environment if they did not have tiny hairs (setae) sticking through the exoskeleton

• Bugscope Teamthis is really cool
• Teacherwhy does it look like a fish?
• Bugscope Teamyou rarely get to see the bare stylet

• Bugscope Teamit loks like a moray eel to me

• Bugscope Teamthat is the business end of the mosquito's proboscis
• Teacherwhat is a styilet?
• Bugscope Teamthis was a mosquito that i squished :)

• Bugscope Teamthe reason we could see it is because Cate smashed the daylights out of it

• Bugscope Teamthe stylet is the part that pierces

• Bugscope Teamthat's why it had little barbs on it like a stinger
• Bugscope Teamso now we are looking at a Gary Larsen cartoon
• Bugscope Teamyeah the little barbs help it cut into the skin like serrations on a steak knife

• 2:13 pm
• Guesthello

• Bugscope TeamHi Maria!

• Bugscope Teamthis is back to the owlfly larva. this has a very simple looking claw

• Bugscope Teamwe also have a preset for the wasp claw so you can compare if you want
• Teacherwhy does a larva need to have claws
• Bugscope TeamMrs Phelps we are working with a school in Mahomet IL
• Bugscope Teamthey make it able to grasp onto things so it can get around and also position what it might be eating a little better

• Bugscope Teamwe ffind claws of some sort on almost all 'bugs'
• Guestwe allredy did this in our school

• Bugscope Teamthis wasp came from Mahomet
• Bugscope Teamfrom Ana

• Bugscope Teamwe were able to put one of your samples on the stub today, very quickly, and this was it
• Bugscope Teamthe potter wasp
• Bugscope Teamit is a pretty nice looking insect
• Teacherthank;l,;
• Guestyes
• Teacher'thanks
• 2:18 pm
• Teacherwe will see you later
• Bugscope Teamyou can see one of its forearms, which are called tarsi
• Teacherbye
• Bugscope TeamBye!
• Bugscope Teamok see you soon
• Teachermy next class will be in here in a few minutes
• TeacherWe will get started around 2::25.....thanks!
• Bugscope TeamCool.
• GuestWe are enjoying look at your insects. I gave my class a preview of our upcoming session on Tuesday.
• Bugscope Teamgreat, Mrs Phelps
• Bugscope Teamoh cool, im sure you are all excited
• Bugscope Team thank you for logging in
• Bugscope Teamwe really like doing this
• Bugscope Teamit is always a little different
• Bugscope Teamwill your students be driving?
• Bugscope Team(the 'scope?)

• GuestYes, I'll let them drive.

• Bugscope Teamyay!

• Guestwhat are we looking at now?
• Bugscope Teamthisis the wasp claw

• Bugscope Teamthe flat part, whoops, was the pulvillus

• Guestyuk

• Guestthe kids are grossed out

• Bugscope TeamCate is resetting a couple of the presets that had moved slightly since she set them up earlier
• 2:23 pm
• Bugscope Teamthis is a spiracle
• Bugscope Teamlike a nose
• Bugscope Teamto a bug
• Bugscope Teamfor breathing, though, not smelling
• Guestwhat grade levels are at your school?

• Bugscope TeamMrs Clark's school?
• Bugscope Teamwe are doing a session with a high school in mahomet, illinois

• Bugscope Team9th 10th 11th grade
• Bugscope TeamMrs Clark will be back on shortly, but this is good since we get to talk to you
• Teacherhi where here
• 2:28 pm
• Bugscope Teamyay!
• Bugscope Teamwelcome back!

• Teacherthank you
• Guestawesome!

• Bugscope Teamthis is a mystery bug with a big forehead

• Bugscope Teamthis is a closeup of the jaw

• Bugscope Teamit is pretty smooth here

• Bugscope Teammany ibsects are much '

• Bugscope Teamd'oh

• Bugscope Teamthat one gort away
• Bugscope Teammany insects are much hairier than this

• Bugscope Teambelow we see the edge of a palp

• Teacherwhat is a palp
  Bugscope Teamthe insect uses them to manipulate its food or to taste/smell food

• Guestthanks for letting us join in

• Teachersure
• Guestwe'll see you next week
• Teacherenytime
• Teacheranytime

• 2:34 pm
• Bugscope Teamyou can try focusing if you want
• Studentwhat school is mrs phelps from?

• Studentwhere are the presets?

• Bugscope TeamMrs C can you try F5?

• Bugscope TeamWe just gave you, as Clark1, control
• Bugscope Teamnice imaging
• Studentwhat is that in the eye?
• Studentcan we be published?

• Bugscope Teamyou mean in the paper?
• Bugscope Teamsure!
• Bugscope Teammrs phelps was form a school in ulysses, ks
• Studentthe news gazette would be nice
• Studenthaha

• 2:39 pm
• Bugscope Teamwe need to get back on the map with the News Gazette

• Studentwhy is there a hair growing out of the eye?
• Bugscope Teamthis is high mag work!

• Bugscope Teamsometimes the insect needs to be able to feel things that might be touching its eye
• Studentdo humans have hairs in there eyes?
• Bugscope Teamand sometimes, like with fruit flies, it is helpful to be able to gauge windspeed
• Studentour eyes*
• Bugscope Teamno but humans do have nerves and can feel when something is touching their eyes

• Bugscope Teamyou would think so since there is the whole "hairy eyeball" thing
• Bugscope Teaminsects do not have nerves on the surface of their bodies because that surface is chitin -- the exoskeleton
• Studentwhats that? the hairy eyeball thing?

• Bugscope Teamso they have to have, instead, setae that project through the cuticle, sense the environment, and report back to the nerves beneath

• Bugscope Teamsometimes people will give you the hairy eyeball or to someone else

• Bugscope Teamyou have done something they did not like
• 2:44 pm
• Bugscope TeamHi all!
• Studentis that like a sucction cup?
• Bugscope Teamyay annie is here
• Bugscope Teamthis is a really nice view of the potter wasp claw
• Bugscope Teamit has lots of tiny setae on it that help it adhere to vertical surfaces

• Bugscope Teamthe tiny setae are called 'tenent' setae
• Bugscope TeamSpiracle
• Bugscope TeamAnnie is here and may be able to help us with the mystery bugs
• Bugscope TeamAn insect nostril!
• Bugscope Teamit is similar to a person's nose

• Studentwhere is the spiracle located? and is it used for breathing
  Bugscope Teamcan you see the 2 small holes along the side? those are each a spiracle

• Bugscope Teamand yes it is used for breaking, or as a pathway for air to get inside the body
• Studentwhat is the mystery bug
• Bugscope Teambreathing
• Bugscope TeamAnnie is working on it
• Bugscope TeamThis is a termite!

• Studentwhy is there no color
• 2:49 pm
• Bugscope Teamwe are using electrons to collect these images

• Studentwhat is this
• Bugscope Teamthis is the part of the mosquito that pokes you
• Bugscope Teamthe electrons from the microscope knock electrons out of the surface of the sample -- or the conductive coating on the surface of the sample

• Studentthe sucking part like a straw?
  Bugscope Teamyes exactly
• Bugscope Teamand those 'secondary electrons' are collected as a signal that gives us the image we see
• Bugscope Teamthe electrons are collected as a signal and there is no color to the signal
• Studenthow can it pierce are skin
• Bugscope Teamjust gray scale imaging
• Studentour*
• Bugscope Teamyou can see those serrated edges to the stylet
• Bugscope Teamthat is how it pierces your skin -- it is very sharp and can cut into your skin

• Bugscope Teamowlfly larva

• Bugscope TeamIt is thin and the tip is sharp, just like a tiny needle. The mosquito injects a chemical into your skin that keeps your blood from coagulating. It is this chemical that makes mosquito bites itch
• Bugscope Teamyou can see that this guy's jaws are set up like a trap
• Bugscope Teamlike heparin
• Studentwhat are those on the back of the bug

• Bugscope Teamit has lots of tiny hairs

• Studentawsome

• 2:55 pm
• Bugscope Teamin real life, when it is alive, the body would not be so small and sort of shriveled

• Bugscope Teamthis is the underside of the head
• Bugscope Teamand this is the middle portion of the jaw
• Bugscope Teamlooks like a desert
• Bugscope Teamwith lots of little cacti on it
• Bugscope TeamCya guys!
• StudentThank you!!!! See you next year.!! we learned alot
• Bugscope TeamThank You!
• Bugscope TeamSee you next year!
• Studentwe thought the same thing about the cacti!
• Bugscope Teamthank you for all your questions and your cool insects
• Bugscope TeamThank you all!!!
