- 10:48 am
- Bugscope Teamhello!
- Bugscope Teamwe are setting up presets now
- TeacherGood Morning! We are currently setting up the remainder of the computers.
- Bugscope Teamwe are making the presets. so just bear with us a little more
- 10:53 am
- 10:59 am
- TeacherI will be leaving my room for a few minutes and will be back soon. Thanks
- Bugscope Teamok see you soon
- 11:04 am
- Bugscope TeamDaddio.
- 11:10 am
- 11:15 am
- 11:22 am
- 11:28 am
- Bugscope Teamwe are ready deby
- Bugscope Teamready to roll!
- Bugscope TeamDeby you have control of the microscope.
- Bugscope Teamyou can click on any of the presets, on the lefthand screen, to get the 'scope to drive to those places
- Bugscope Teamyou can also click on the image, and the microscope will center on that position
- Bugscope Teamplus, of course, you can change the mag, focus, etc.
- TeacherI am bringing in the students in 3 minutes
- Bugscope Teamsuper cool
- 11:33 am
- Bugscope Teamplease let us know when you have questions or problems
- Bugscope TeamCate, Daniel, and I are here to help.
- Bugscope Teamthis is a small cricket
- Bugscope Teamyou can see its compound eye behind and above the palp that is folded over its face
- 11:40 am
- TeacherThe students are currently at the computers. We are ready to begin
- Bugscope Teamsweet!
- Bugscope Teamplease, everyone, feel free to ask us questrions, about anything!
- Bugscope Teamnow we're looking at the head, a bit closer
- Bugscope Teamyou can see that the live images from the microscope are in black and white -- in grey scale
- Studentcan u please put more magnification
- TeacherWhat are the holes on the head
Bugscope Teamwe can see an opening where the base of the antenna connects to the head
Bugscope Teamand we can see that the compound eye is faceted
- StudentWhat are those hairs?
Bugscope Teamhairs in insects can be sensory: sometimes they sense hot/cold, sometimes they taste and smell with them, sometimes they are touch- and wind-sensitive
- Bugscope Teamthe hairs -- or setae, or bristles -- we see now are for proprioception, which is self-sensing; they let the cricket know when it is moving its head
- Studentwhat are those big hairs
Bugscope Teama lot of the hairs, which we are supposed to call setae since they aren't on mammals, are for sense of touch
- 11:45 am
- Studentwhat are those lines
- Studentwhat are those bumps on its skin?
Bugscope Teamthe small bumps to the right that we don't see right now are the ommatidia -- the individual eye facets
- Studentwhere does the sound of a cricket come from and can you magnify that part
Bugscope Teamit comes from the leg, which has a big thing kind of like a resonator on it
- Studentcan we please view a different insect
Bugscope Teamhere you go!
- Bugscope Teamthis is a true bug. true bugs are called hemipterans. and this one is a leafhopper
- StudentAbout how many cells does this organism contain?
- Bugscope Teamits compound eyes are streamlined into its pointy head
- Studentwhere can we find these insects?
- TeacherWhat is currently on the right side of the slide?
Bugscope Teamthe insects are sitting on double-stick carbon tape. the tape has a lot of little bumpy features on it
- Studentcan we please view salt crystals
Bugscope Teamyour teacher can control the microscope now and can click on the preset for the salt crystals if she wishes to
- Studentcan we see its cells
Bugscope Teamwe can see evidence of cells, but we are looking at the outside of the body -- at the exoskeleton
- Bugscope Teaminsects and comparable arthropods have an exoskeleton, like a shell, or like a coat of armor
- StudentWhat are those
Bugscope Teamthose are salt from a Wendy's restaurant
- Studentwhere can we find these insects?
Bugscope Teamthey are mostly local to Illinois and Indiana, near where we live
- 11:50 am
- StudentWhat is the bubble?
Bugscope Teamlikely it is a droplet of fluid, perhaps some hemolymph, which is what insect 'blood' is called
- Teacherhow many fangs do spiders have
Bugscope Teamthey have 2 with pores at the tips to inject the venom
- Studentdo all spiders have fangs?
Bugscope TeamI think so -- I am not sure about those coconut spiders. Almost all spiders for sure have two fangs, and they inject venom into their prey that dissolves the internal organs, which the spider can then suck up like a milkshake
- Studentwhat are those strings and little hairs?
Bugscope Teamthese are setae that are likely sensory, helping the spider sense vibration
- Bugscope Team(this is Scot, using the name SJ on another computer)
- Studentcan the spiders see in color or only black and white
- Studentwhat type of spider is this
Bugscope TeamIt is some kind of grass spider
- Studentare there cells in fangs?
Bugscope Teamoriginally there were cells; I am not sure how the exoskeleton and the chitin it is made of is considered at this point
- Studentwhat are those debree on the hexogons
Bugscope Teamsome dust maybe that got on the eye
- Studentis that bacteria on the head?
Bugscope Teamsometimes we see bacteria but not for sure here yet
- 11:55 am
- Studentcan i use this spider as a pet or its dangerous
Bugscope Teamnot dangerous to you. it's not a black widow or brown recluse
- TeacherWhat is each hextagon
Bugscope Teameach hexagon is called an ommatidium, and it is an individual lens of the compound eye
- Studenthow do you get the insect on the slide if it's not flat
Bugscope Teamit's not really a slide; it's an aluminum disc 1.75 inches in diameter
- Bugscope Teamthe samples are not flat; we're focusing on them using the scanning electron microscope, which lets us view things that are 3-dimensional
- Studentcan you change the magnification so we can see the whole fruitfly?
Bugscope Teamyes, or your teacher can
- Studentwhat is that that line structure
Bugscope Teamthose are the divisions of the facets, or ommaditia
- Studentwhat is that stick coming out of the hexogon?
Bugscope Teamthat is a seta --- a sensory seta that helps the fly sense wind and touch
- Studentwhat is that
- Studentwhat are those two antennas?
- Bugscope Teamthese are the cercopods -- the pincers of an earwig
- Bugscope Teamthis is a male earwig
- Studentdo the pincers have venom?
Bugscope Teamno they just pinch
- Studentdo you have a crab to show us
Bugscope Teamno crabs today -- if we had a rolypoly, that would represent crustaceans
- TeacherDoes that contain any poisionus liquid in it?
Bugscope Teamno it is just a pincer, for protection
- 12:00 pm
- Studentwhat do they do?
Bugscope Teamlooks like it would be a good wire stripper, but it is used to pinch things that try to bother the earwig
- Bugscope Teammale earwigs have strongly curved cercopods, and female earwigs have cercopods that are much straighter
- Studentwhat are those black structures
Bugscope Teamto the right? those are bubbles in the carbon tape the insects are stuck to
- Studentwhat are those dots in the background
Bugscope Teamthat's part of the carbon tape that the insects are stuck to
- Studentwhat are those bubbles around it
Bugscope Teamthe carbon tape has little bubbles or craters in its surface
- Bugscope Teamthis is a cute little tiny beetle that Daniel found in his house.
- TeacherOf all the insects here which is thew most dangerous?
Bugscope Teamit is funny -- I would say the mosquitoes are most dangerous, but I accidentally put all male mosquitoes on today's stub
- StudentRight now can the insect move
Bugscope Teamno it is dead and dry
- Studentwhat are those circles on its face
Bugscope Teamthe tiny circles were the eye facets -- the ommatidia
- Bugscope Teamwe can tell that this is a male mosquito because it has ornate antennae
- 12:06 pm
- Bugscope Teamthe male needs to have those fancy antennae with vibration-sensory organs in them so it can tune into the noise of the female wings
- Studentwhat are those rigid flakes
Bugscope Teamthose are scales, which butterflies, moths, and silverfish have as well
- Studentdo you have a bee that we can see
Bugscope Teamthere is a yellowjacket wasp
- Student sckodsvjofdjvifdj\
- Teacherwhats are the wires coming out of the big fuzzy stick
Bugscope Teamthose are parts of the antennae
- StudentWhat makes the mosquito if all it does is make you itch?
Bugscope Teamthe saliva makes you itch; it gets a blood meal so it can lay its eggs successfully
- Studentis there a difference between a male and female mosiquito
Bugscope Teamthe males do not drink blood; sometimes they drink nectar, from flowers
- Studentdo mosquitoes eat anything besides blood?
Bugscope Teamthere are some species of mosquitoes in which the females and males both drink nectar, but not in the U.S.
- Studentwhat are those bubbles on the face
Bugscope Teamthose are the spider's eyes, some of them
- Studentwhat are those BUBBLES
Bugscope Teamthose are the eyes :)
- Studentcan we see the yellowjacket wasp?
Bugscope Teamyes as soon as your teacher drives the 'scope to that position
- Studentwhat make the mosquitos so dangerous?
Bugscope Teamthey pass diseases on to people, like malaria and yellow fever and West Nile virus
- Studenthow many\
Bugscope Teamwe see 7 eyes; usually there are 8
- Bugscope Teamthe head and the thorax are one piece in a spider, called the cephalothorax
- Studentwhat are those strings coming out of the face
Bugscope Teamthose are setae, or hairs. they help with sense of touch, or maybe vibration in this case
- 12:11 pm
- Teacherthe bees are not there
Bugscope Teamsorry I called it a wasp in the preset
- Bugscope Teamits mandibles -- its jaws -- open left and right, like a gate
- Studentcan you magnify it more
- Studenthow does the spider see if its eyes are covered?
Bugscope Teamit cannot see if its eyes are covered, but it is very good as sensing vibration
- Studentwhats the objects that are on top of eachother
Bugscope Teamthose are the mandibles -- its jaws
Bugscope Teamyou can see that they are kind of like forks, or sporks
- Bugscope Teamwe see something below the mandibles that looks like a mouth opening
- Studentwhat is that random dot on the jaw
Bugscope Teamit could be pollen or just some juju
- Bugscope Teamthe spider has lots of plumose setae like that
- Studentwhat is juju

- Teacheris that a mouth
Bugscope Teamyes it is!
- Bugscope Teamthis is a tiny ant called a plier ant that has those super creepy looking jaws
- Bugscope Teamthe compound eyes are on the bottom of the head
- Studentsorry mybad
- Bugscope Teamplier ants specialize in feeding on collembola, which is what springtails are called\
- 12:16 pm
- Bugscope Teamthe jaws are awesome
- Bugscope Teamjuju is what we call things we don't recognize, often just some kind of debris
- Bugscope Teamthis is the opening to another universe
- Studentwhat are those oval structures
Bugscope Teamthose are pollen grains
- StudentWhat are those hairs/threads on every insect
Bugscope Teamthey're called setae, and they are sensory; they are necessary because insects do not have skin -- instead they have a shell that cannot feel
- Studentwhat are those lines?
Bugscope Teamthose are cracks in the tape way up close
- Teacherwhat are those beans around it?
Bugscope Teamlily pollen
- Studentdo you have a bee that we can view?
Bugscope Teamwe just looked at a wasp -- a yellowkacket; that is as close as we get today
- Bugscope Teamthe exoskeleton is made of chitin, which is similar to the keratin in your fingernails
- Teacheris there any questions that other classes usally ask that you think we woud be interested in knowing
Bugscope Teamhere we will show you the inside of the specimen chamber in a sec
- 12:21 pm
- Bugscope Teamsometimes students ask what the samples are coated with, and is the microscope easy to use, and why are the samples in gray scale instead of color
- Bugscope Teamthe chat and images from today can be accessed anytime in the future from the member page. the names are made anonymous
- StudentWhat is this
Bugscope Teamthis is the inside of the vacuum/specimen chamber
- Bugscope Teamthe cone-shaped thing at the top is where the electrons come from
- Bugscope Teamthe platter in the middle is the sample we are looking at
- Studentaround how big is the whole microscope?
Bugscope Teamthe main part is about the size of a fridge
- TeacherWhat are the answers?
Bugscope Teamthe samples are coated with about 20 nanometers of gold-palladium, an alloy
Bugscope Teamit is thicker than we would coat normal samples with
- Bugscope Teamthe microscope is easy to use, and fun, and we rarely use it to look at insects unless we are running Bugscope
- Studentwhat are those circular structres
Bugscope Teamthey look like dried drops of some sort of liquid
- TeacherCan you send us a picture of the microscope and lab you are working at>?
- Bugscope Teamthere is no color because we are using electrons, which are super small -- much smaller than the wavelengths of visible light -- to look at the samples
- Studentcan we view an image of the actual microscope
- 12:27 pm
- TeacherWhat do you usually look at
Bugscope Teamwe train people to look at bacteria, cells (sometimes zombie cells), lots of devices they have made from PDMS, self-healing polymer capsules, filters, all kinds of stuff
- Studentwhat are zombie cells?
- Studentisnt this microscope supposed to be complicated to operate?
Bugscope Teamit is helpful if you know the theory behind what you are doing so you can get the best images
- TeacherCan we see a zombie cell
Bugscope Teamthey look like normal cells but I am sorry we do not have any today
- TeacherWe are learning about animal and plant cells. Do you have any individual cells for us to see?
- Studentis the stinger poisionus?
Bugscope Teamit has a venom in it that would hurt but not cause lasting problems
- Bugscope Teamthe cells have to go through some preparation before looking at them under this microscope because of the vacuum
- Studentcan we see the retina of an eye?
Bugscope Teaminsects do not have those kinds of eyes; we could see them if we had them; I have done it before, with rabbits
- Studentwhat are brochomes
Bugscope Teamthey are nanoparticles that leafhoppers produce; they are 250 to 400 nm in diameter
- Studentwhat are zombie cells?
Bugscope Teamthey are replicas of individual cells made out of nanocrystalline silica
- 12:32 pm
- Studentwhat are those dots all around it?
Bugscope Teamthis shows how small these are; they are hard to get in focus at this long working distance
- Bugscope Teamsometimes we see bacteria
Bugscope Teambacteria are individual cells, and there are likely some here but sometimes they are hard to find
- Bugscope Teamthat was a spiracle, through which insects breathe
- Bugscope Teamand here we are looking at a few wing scales, which produce structural colors as well as normal pigmented colors
- TeacherWhat is the highest magnification that you can magnify?
Bugscope Teamwe can go to over a million times, but for research-quality images it is rare to hit 200,000x.
- Studentwhat is the hole?
Bugscope Teamthis is a spiracle. it's a breathing port that is kind of like a nostril
- Bugscope Teamit is a spiracle, through which insects breathe; it connects to tracheae, which are little ducts that go to organs inside of the body
- TeacherDid you ever look at a brain
Bugscope Teamwe haven't in the past, but some people do
- Bugscope Teaminsects can open and close their spiracles to let air in or out
- Studentwhat is a fruit fly spiracle?
Bugscope Teamall insects have spiracles, but this one is on the thorax (like the chest) of a fruitfly
- 12:37 pm
- Studentone tree hilllllll
Bugscope Teamhaha Yeah!
- Studentare fruitflies only atrracted to fruit
Bugscope Teamthey are said to eat the mold that gets on fruit; I'm not sure what is and is not correct. some people have told us that what we call fruitflies are vinegar flies\
- Bugscope Teamwe should be able to see the haltere
- Bugscope Teamdown lower on the body
- Bugscope Teamthe round thing is the haltere
- Bugscope Teamyou can see loose scales on the body as well
- Studentthanx scott
Bugscope TeamYay! Thank You!
- Studentwhat is haltere?
Bugscope Teamthey beat opposite the wing to help balance the fly as it flies
- Studenti am getting a fruitfly as a pet next week any advice?
Bugscope Teamyou can feed them medium and they will breed if you get more than one and they are not all boys or girls
Bugscope Teamit will be hard to put a leash on it if you want to keep it from flying away
- Studentis that living things on the organism
Bugscope Teamthe scales come from other insects
- TeacherThank you so much. We will be going to our next class now. We greatly appreciate the interactive presentations
Bugscope TeamThank You!
- Studentthank you
- 12:43 pm
- Studentthank you very much!
