- Bugscope Teampumping down..
- 9:55 am
- Bugscope Team2.7 x 10-4 mBar
- Bugscope Team2.1
- 10:01 am
- Bugscope Team2.0
- Bugscope Team1.8
- 10:08 am
- Bugscope Teamwaivering... 1.7
- 10:13 am
- Bugscope Team1.6
- 10:20 am
- Bugscope Teamhi we are still waiting for the vacuum to finish pumping down. then we will do the presets
- Bugscope Teamand after that you can have control
- TeacherI am so excited. I will start setting up the kids. They are at art. I am doing this in our lab.
- 10:29 am
- Bugscope TeamTeacher we are going to take the big bee out because we think it may be too juicy, still, to let the vacuum pump down enough to use the 'scope.
- Bugscope TeamSo you will see me in a second...
- Bugscope Teamtaking the bee out of the chamber
- Bugscope Teamnow we are pumping down again. we *think* that was the culprit...
- 10:44 am
- TeacherHow is it going?
- Bugscope Teamapparently the bee wasnt the problem.
- Bugscope Teamonce we find out what is the problem we'll be able to make some quick presets and get you going
- 10:56 am
- TeacherWe are all in the lab. Ready when you are.
- Bugscope Teamugh we are very sorry -- something we had collected for your session today was too juicy to let the vacuum pump down. so we have put another Bugscope sample in the 'scope. There is a bee among the insects, plus a ladybug, a centipede, a few flies, a mosquito...
- Bugscope Teamnow we are pumping that sample down; it should go much more quickly
- Bugscope Teamonce it is pumped down we will turn on the electron beam and start imaging
- Bugscope Teamyou will be able to see how we set things up -- the things you would normally not see
- Bugscope Teambut we will work as quickly as possible
- TeacherThat's okay. We know trying new things is full of the unexpected.
- Bugscope Teamso what we are looking at right now is the vacuum chamber, and the little platter in the middle bottom portion of the screen is a bunch of bugs
- Bugscope Teamthey've been coated with gold-palladium to make them conductive, and before that they were air-dried
- 11:01 am
- Bugscope Teamwhen the vacuum gets to be good enough we will switch to the secondary electron detector and start beaming electrons at the sample
- Bugscope Teamthey come from the conical thing at the top center of the image we see now
- Bugscope Teamthe electrons will raster across the sample -- wherever we point them
- Studenthow long does it take to air dry a bee
Bugscope Teamit takes at least a few days
- Bugscope Teamand they will excite electrons from the conductive coating -- the gold-palladium allow -- that we put on the samples
- Bugscope Teamthat was a very big bee, but it may not have been the bee that was the problem
- Bugscope Teamalso depends on the bee
- Bugscope Teamthey can be very big- like solitary bees or bumble bees
- Studenthow juicy
Bugscope Teamthe 'juiciness' is from the hemolymph -- the 'blood' of the insects
- Bugscope Teamit may also be because we put plant material in for today's session, and plants, because the cells have thick walls and waxy coatings, can remain moist longer
- 11:07 am
- Studentdo bees have hearts
Bugscope Teamyes but they are a bit different from our own hearts
- Studentwhat is the hemolymph
Bugscope Teamthat is the bug blood, it can sometimes be green when you see it
- Bugscope Teaminsects and other arthropods like them have 'open' circulatory systems
- Studentwhat climate do bees like best
Bugscope Teamthey like warm temperatures. Most insects do. That's why in the south there is such a huge variety of insects
- Studenthow old can bees live to
- Studenthow long is a bees life
Bugscope Teamthe queen can live the longest- 2-5 years. The drones live for a little over a month and the workers live up to 4 months
- Studentdo bees have teeth
Bugscope Teamno but they do have jaws that sometimes are forked or serrated. They open out like a gate
- Bugscope Teamwe are so sorry--
- Bugscope Teamthe drones are the males and the workers (the bees you see most often) are the females
- Studenthow many times does a bees haert beat a second
- 11:13 am
- Studentwhy are bees fuzzy
Bugscope Teamthey are fuzzy in part because they have many sensory setae on the surface of their exoskeleton
- Studentare queen bees allways the same color
Bugscope Teamqueen bees look similar to the rest of the bees, only her abdomen is longer. Most beekeepers dab a little paint on her abdomen to distinguish her form others
- Studentwhy are bees juicey
Bugscope Teamall insects are juicy, on the inside
- Studenthow long can a bee fly for
- Bugscope Teamthe setae are mechanosensory, meaning they can help the bee sense touch, and some of them are chemosensory, meaning that they can help the bee smell scents, like of flowers, in the air
- Studentdo bees fight
Bugscope Teambees are not aggressive about their territory, unlike wasps
- Bugscope Teambees from different hives or different species may fight
- Studenthow many speshes of bees do we know about
- Studentdo bees have a sence of humer
- Studentwhat is a exoskeloton
- Studentdo bees have ears
Bugscope Teamthey dont have ears but they use their antennae smell and sense other things
- Bugscope TeamAfricanized honeybees are aggressive. But as Cate says most bees are not.
- Studentare queen bees allway the same color
Bugscope Teamyes they even look very similar to the rest of the bees
- Studentwhat is it
- Student is that its leg
- Bugscope Teamthis is a fly's claw
- Bugscope Teamthe end of the leg
- Studenthow many baby bees dose a qween have
Bugscope TeamThe queen lays about 1200 eggs per day, about 200000 per spring
- 11:19 am
- Studentis that a eye
- Studentwhat are we looking at
- Studentis it an eye
- Bugscope Teamyes this is a fly-s compound eye
- Bugscope Teamit has a small pollen grain on it
- Studentwhat is on the eye
- Studentdoes a fly look frew all those eyes or just one
Bugscope Teamthe fly has two compound eyes and three simple eyes called ocelli
- Studenthow many dots does a fly have in iy
- Studentwhat do flys eat
Bugscope Teamthat depends on the fly. The normal housefly eats from garbage or our food
- Studentwhat is this
- Studentwhat are we seing now
- Studentwhat are we looking at
Bugscope TeamWe are on a honeybee now
- Studentwhy are there hairs on it
Bugscope Teaminsects are very hairy. Those hairs called setae (see-tee) when found on insects are used to help the insect feel what's going on around it in its environment. They help to taste/smell, feel vibrations, touch, sense air movement
- Studentare we looking at a bee
Bugscope Teamyes we are look at the base of the antenna
- 11:24 am
- Bugscope Teamfruit flies will eat enzymes from rotting fruit
- Studentis that a ant
Bugscope Teamthis is a fly, but that was a good guess. we thought it was a wasp at first, and they are related to ants
- Studentis that a ear
- Bugscope Teama mite!
- Bugscope Teamthis is one of two mites we just found on the fly-s wing
- 11:30 am
- Student do mites have ears
Bugscope Teamthese do not have eyes, and they likely do not have ears
- Studentwhat does a mite eat
Bugscope Teamdust mites eat dander and human skin flakes, some mites are parasites like we see today, and they are like ticks
- Studenthow long do flys live
Bugscope Teamfrom a week or so to maybe 6 weeks or longer, it varies
- Bugscope Teammites are kind of a mystery, and we don't always know what they eat
- StudentWhat is that thing
Bugscope Teamcan you guess, now?
- Studentis that a maskeeto
Bugscope Teamyay!
- Bugscope Teamthis is a mosquito
- Bugscope Teamfor sure
- Studentis that his eye
Bugscope Teamyes that bumpy region we just saw was the compound eye
- Studentwhere does it suck blood from
Bugscope Teamright where we are now
- Bugscope Teamthis is the proboscis
- Studentare those the leg
- Studentdo they have hands
Bugscope Teamlet's go look for the hands
- Bugscope Teamthe biting part has lots of sharp blades, and it is inside this, which is a kind of sheath
- Studenthow much blood dose a mosquito
Bugscope Teamthey take in at least several microliters -- a few big drops, to us
- 11:35 am
- Studentam i looking at the hand
Bugscope Teamyes this is a mosquito claw which is the same as a hand
- Studenthow many pieces of compound eyes are there
Bugscope Teamthat depends on what we are looking at -- with a wasp there may be 5000 ommatidia -- the individual facets of the eye
- Studenthow dos it make a mosquito bite
Bugscope Teamit has multiple mouthparts in its sheath where some are serrated like knives and cut into the skin, then there is a tube that goes in injects an anticoagulant to make the blood flow freely without clotting, and then a tube sucks out the blood
- Bugscope Teamthis is the centipede
- Bugscope Teamas creepy in the microscope as in real life
- StudentWhat's inside the centipede?
Bugscope Teamguts, a trachea (which is the equivalent of our lungs and throat), the heart, brain...
- Bugscope TeamTeacher you can go ahead and control the microscope if you want, or we can confer control to another student
- Studenthow many legs does it have
Bugscope Teamthis has 17 pairs of legs
- Studentcool
- Studenthow much blud does a centipede have
Bugscope Teamit has hemolymph kind of like an insect does, and of course it is related to its size, but probably less than half a milliliter
- Bugscope Teamthis is one of those 'moustache bugs'
- 11:40 am
- TeacherCan Student Pairs H have the controls, please?
Bugscope TeamH has control
- Bugscope Teamsee the compound eye?
- Bugscope Teamthis is a fierce insect eater
- Studentya
- Bugscope Teamit has chelicerae, and fangs like a spider
- Bugscope Teamsorry you all didnt get to see the little collection of flower pollen I collected
- Studentwhat is the most poisenes bug?
- Studentwhat kind of insects does it eat
Bugscope Teamwhatever it finds in the house -- this is a house centipede, and it can eat anything smaller and maybe a few things larger
- Studentthis is cool
- Studentwhat is this
Bugscope Teamwe are looking at the underside of the centipede -- the ventral side, where we can clearly see the feet, and the joints of the legs
- Bugscope Teambut it does not really eat -- it sucks the juice out of the insect
- TeacherHow about Pair C?
Bugscope TeamC has control
- Bugscope TeamYou can switch to a different insect by clicking on a preset in the lower right if you want
- Studentwhat is this
Bugscope Teamsome dirt on the leg of the centipede
- Studentis this a fly
Bugscope Teamthis is a centipede, but whoever is driving can click on one of the other presets that go to a fly
- Bugscope Teamwe are on the leg
- Student is that a pollen gran
- Bugscope Teamthe bumpy stuff in the background is the carbon tape we stick the insects on
- Bugscope Teamspeaking of bumpy
- 11:45 am
- Bugscope Teamvery round
- Studentwhat is that
Bugscope Teamwe are on the centipede head
- TeacherStudent Pair G would like to try.
Bugscope TeamG has control
- Bugscope Teamif you had compound eyes you would have very good peripheral vision
- Studentits cool
- Studentwhat is the strongest bog
Bugscope TeamThe strongest insect is reported to be the dung beetle, which can pull 1,141 times its own weight
- Bugscope TeamThe bumpy part was the eye
- Studentcan we look inside the eye
Bugscope Teamwe can't look inside it unless it is cracked open
- Bugscope Teamalso, if you had compound eyes it would be hard to buy sunglasses, but you would be able to register motion very quickly
- Studentwhat are we lookinr at
- Bugscope Teamthis microscope does not allow us to see through things
- Bugscope Teamplease choose one of the other presets to go to another insect
- TeacherStudent pair E
- Studentwhat is the bigest bug
Bugscope Teamlobster
- Bugscope Teamand technically there is a mite (which is an arachnid) that can carry a bit more for its weight
- Bugscope TeamI was just kidding about the lobster, because you know it is a crustacean
- Bugscope Teamthe biggest insect may be the Goliath beetle, which is as big as your fist
- 11:50 am
- Studenta lobsters a bug
Bugscope Teamnot really; they have two sets of antennae, for example, and insects have only one set
- Bugscope Teamthere are also walking sticks that may be 12 or 15 inches long
- Studentare we still looking at a centiped
Bugscope Teamand yes we are on the centipede still
- Bugscope Teamthat hole is the poison pore
- Bugscope Teamthe poison pore!
- Studentare we still looking at the lobster
- Studentis that a claw?
Bugscope Teamthose are the fangs
- TeacherStudent Pair B
Bugscope Teamb has control
- Studentwhat is the most poisenous bug
Bugscope Teamnot sure.
Bugscope Teamthe most venomous is reported to be a harvester ant.
- Studentcool
- Studentis that a pincher
- Studentwhy are bugs so tiny
Bugscope Teamthey cannot be much bigger because the way they breathe cannot support a larger body size
- Studenthow do bugs mate
Bugscope Teamoops I answered the hobby questio... they mate much like other animals, and they usually have eggs
- StudentWhat is its hobby?
Bugscope Teamthey mate kind of like animals
- Studentwhat colers do Centipede come in
- Studentbugs arent always small right
- Studentwhat is the bumpy stuff in the back round
- TeacherStudent Pair K
- 11:55 am
- Studenthow many eags can a Centipede lay
Bugscope TeamThey can lay up to 151 eggs each spring
- Bugscope Teamthe harvester ant can kill a rat or rabbit with 12 stings
- Studenthow long dose it live
Bugscope Teamcentipede lifespan is 5-7 years
- Studentit looks like like a ant
- Studentcan we look at a diferent bug
Bugscope Teamhow about a mosquito?
Bugscope Teamwhoever is driving can change to another preset to get to another insect or bug
- Studentwhat is that
- TeacherStudent pair I
- TeacherStudent M
- Bugscope Teamthis is kind of sad -- the base of the antenna, where it is missing
- Studentwhat is the most vicous bug?
Bugscope TeamI think it is a horsefly
Bugscope Teamthere is an asian giant hornet that can spray venom and dissolve human skin- that's pretty viscous
- TeacherStudent Pair D
- 12:01 pm
- Student awesome
Bugscope Teamyay!
- Studentdo you have a squirpion
Bugscope Teamnot today
- Bugscope Teamthis is the wing of the mosquito
- TeacherStudent Pair A
- StudentWhy don't you feel a misquito bite
Bugscope Teamthey are sneaky, and some insects, like bedbugs, have anesthetic saliva that you cannot feel
- Studentif you have a scorpion can we see it
Bugscope Teamwe don't have one today, but they are often not that interesting to look at, so please do not feel bad about it
- Bugscope Teamthere are many species of mosquito, and I imagine some of them have anesthetic saliva
- TeacherStudent Pair J and that is everyone.
Bugscope TeamJ has control
- 12:06 pm
- Studenthow long do mosquito live?
Bugscope Teama few days to a few weeks
- Bugscope Teamthere is a walking stick with a body that is 14.2 inches long
- Studentthank you
- Studentthank you
- StudentThank you!!!!!!!!!!!!!
- Studentthanks so much bye
- Bugscope Teamsorry we didnt get to see much pollen or pollenators
- Bugscope Teamwe enjoyed working with you and hope to see you next year
- Studentthank you it was verey cool
