- Bugscope Teamhello!
- TeacherDid Alex mention I'm travelling to U of I tomorrow to bring my son (a high school senior) in for a college visit. He did Bugscope once at his school. He looked at teeth. Anyone remember?
- Bugscope Teami mentioned that to scott, yes, i think i responded to you, but if i forgot to send the email, it's all good, just come on over, and we'll give you a tour
- Bugscope Teamwe are done setting up presets and have unlocked the session. Feel free to start moving around
- Bugscope Teami'm alex by the way
- Bugscope Teami'll logout as scott now
- Bugscope Teamyou can click on a preset to the lower right or you can drive manually using the controls
- TeacherScott, how are you Alex?
- Bugscope Teamhere i am!
- StudentHi everyone!!!
- Bugscope Teamwell, scott logged in as himself, and i was using his login.
- Bugscope Teamhello robyn!
- Bugscope Teamhi folks! welcome to bugscope.
- Bugscope TeamHello all
- 4:13 pm
- Bugscope Teamwe've got annie. annie is a killer phd student in entomology, she'll answer all the hard *insect* questions...
- Studentthanks alex
- Bugscope Teamhaha
- Bugscope TeamI will try
- TeacherWe have about half the class here. We will start driving in a moment.
- Studenthi cate :)
- Bugscope Teamok, feel free to ask us any questions you have, about insects, the scope, anything
- Studentnice hat eric
- GuestI'll be back as a student
- TeacherWow, why all the presets? I really like the cicada for our student, Joris. He's not here yet.
- Guestthere's no student tab
Bugscope Teamjeehyun, are you in the same computer lab?
- Guestit's ok
- Bugscope Teamit's a cicada killer, which is a really big wasp (so big we only have its booty so we can see the stinger)
- Guesti'm jee
- 4:18 pm
- Bugscope Teamah, yeah, i see, it doesn't work for me either, a bug in the software!!! hey, it'll be totally fine, we made the guest functionally the same as student, so you will have all the same functions as any other student
- GuestThanks, alex
- Bugscope Teamwe'll work on fixing the bug
- Bugscope Teamthese are housefly antennae, which have 2 parts
- StudentIt looks like there is hair on the antennaes...what is that used for?
- Bugscope TeamThese are aristate antennae
- Bugscope TeamOnly flies have aristate antennae
- StudentWhat do they do?
- Bugscope TeamThe hairs on the antennae (and all over the fly) help the insect to sense its environment. Insects taste, smell, hear, and feel using the hairs on their bodies
- Bugscope TeamBut we don't call them "hairs," we call them setae
- Bugscope Teamthose hairs are called setae, they stick though the exoskeleton and are attached to nerves underneath
- 4:23 pm
- Bugscope Teamhere you can practice focusing
- Bugscope Teamthis is a female-- you can tell because the spacing of the eyes is so far apart
- Studentis this the eye?
Bugscope TeamYes, on the left side of the screen is one of the compound eyes
- Bugscope Teamwell--left to middle
- Bugscope Teamthe individual facets are called ommatidia
- 4:28 pm
- Guestwhy is it honey-comb-like?
Bugscope TeamI guess the theory is that the honey comb shape is the most efficient shape to fill a round surface (think soccer ball)
- Studentwhat are the eyes sticking out of the eyes?
Bugscope Teamthose would be setae. We believe when we see these short stiff hairs, they help the insect sense wind movement
- Student oops what are the hairs sticking out of the eyes?
- Bugscope Teamso they are navigate the air drafts, or know when a hand or flyswatter is coming at them
- Bugscope Teamif you remove the setae from the eye, the insect doesn't know how to navigate in the wind
- StudentDo human eyes have something similiar to setae to sense wind movement?
Bugscope Teamnot really...
- Bugscope TeamAnd every time I tell that story, I think of the poor graduate student who had to shave the fly's eye
- Studentwhat is on the eye, the dark parts?
Bugscope Teamthat might be where the detecter wasn't getting as much signal back from the sample (it was angling away from the detector)
- Bugscope Teamthis is a ladybug face
- Bugscope Teamyou can't see the eyes 2 well, but you can see the mouthparts
- StudentIs it the underside or the top?
Bugscope Teamthe underside
- 4:33 pm
- StudentWhere exactly is the mouth?
- Bugscope Teamthere is a hinged jaw and below that are a set of palps and to the left you can see a bigger palp (it looks like a vaccuum nozzle)
- Bugscope Teampalps help manipulate or taste food
- Teacherwhat is that thing that looks like a claw?
Bugscope TeamThe two little hooked things that kind of look like legs are labial palps. Right above the labium are (were) the mandibles (the jaws)
- 4:39 pm
- Bugscope Teamwe are close to a claw now
- StudentAre those hair looking things the same kind of thing as the hairs on the fly?
Bugscope TeamThey serve similar (if not identical) functions. Different setae have different functions.
- Studentwhich way should we drive to see the claw
Bugscope Teamit is to the right
- Bugscope Teamyep, they are setae. but setae come with different functions, some are chemosensory, others are mechanosensory, and there are other types too.
- Studentdo thse setae serve the same purpose as the flys setae?
- Bugscope Teamthink of an insect wearing a suit of armor, normally you wouldn't be able to feel much. With these hairs poking through (attached to nerves) they can feel what's going on around them
- Bugscope Teamkeep going you will see it
- Bugscope Teamlike if you build a little armor suit for your cat and stuck him in there, but made little holes for her whiskers, that would like like setae
- Bugscope Teamyou can see a type of ball and socket joint
- Bugscope Teamthere is is in the middle
- Bugscope Teamthe round part is called the coxa, the second segment of the leg is the trochanter--but we can't see those parts anymore
- StudentI have students driving at the teacher computer. They are doing a great job.
- 4:44 pm
- Bugscope Teamit can be difficult to drive but you seem to be doing great
- Studentis this the claw?
Bugscope Teamthis is the bottom of the claw
- Bugscope TeamThe claw is sort of out of focus right now
- StudentHow's that for focus?
- Bugscope Teamanother option you can do is we can confer control to the student who would like to drive instea.d of switching out the teacher one if you want
- Bugscope Teamits getting much better!
- Bugscope Teamso this is half the claw
- Studentis that more setae?
Bugscope Teamthat is called tenet setae, which as annie said, asks as suction cups
- StudentWhat are we looking at now?
- StudentThese setae are on the tarsus. Is that the underbelly?
- Bugscope Teamtenet or tenent, comes from the root tener, spanish for 'to hold'
- Bugscope Teamthis is another image of the special setae that allows the insect to walk onvertical surfaces
- 4:49 pm
- StudentCould you give the controls to Nancy?
- Bugscope Teamnancy, you are driving now
- StudentI need to get me some of those!
- Bugscope Teamyou should see controls on your right, magnify, nav, focus and adjust
- StudentWhat are those desert-like grooves?
Bugscope Teamafter insects die, they tend to dry out a bit. the cracks are where it used to be more "fluffy"
- StudentDo all insects have similar things to walk on vertical surfaces?
- Bugscope Teamthis is cool, usually the ommatidia are a little deflated after a mosquito dies, but this one held up pretty well
- Bugscope Teamwhen you take the mag all the way down, it looks like asome hunchback monster
- StudentAre those antenna coming out next to the eyes?
Bugscope Teamyes, those are the antennae
- Bugscope TeamAlex is Annie, Annie is Alex!
- 4:54 pm
- StudentIs this the end of the stinger?
Bugscope TeamMosquitoes don't have stingers, they actually bite you. The only insects with stingers are wasps, bees, and ants.
- Studentcan you give the controls to mulder?
- Bugscope Teamhere's the bumblebee
- TeacherPlease let Paula drive.
- Bugscope Teampaula has control
- StudentAre the parts that criscross parts of the jaw?
Bugscope Teamyes they are
- Studentwhat are those two blade like things crossing each other?
Bugscope TeamThose are the jaws (aka the mandibles)
- 5:00 pm
- StudentDo bumblebees, or insects in general, have pores?
Bugscope TeamThey all have pores of some description
- StudentDo all insects have eyes with all those different sections on them? Which insect has the most?
Bugscope TeamAll insects with eyes have compound eyes as adults. There are some eyeless insects, that have lost their eyes secondarily. These insect usually live in caves or underground. There is no way or knowing which insect has the most ommatidia
- Bugscope TeamPores in insects have many different functions. Some pores are on glands that excrete pheromones or defensive compounds. The waxes that insects use to waterproof their cuticles also come out of pores.
- Bugscope Teamthere is the stinger
- Bugscope Teamyou found it!
- Guestwhat are the layers? skin?
Bugscope TeamThe layers are segments of the bee's abdomen
- Bugscope TeamBecause there are probably a million species of insects
- TeacherZoot alors!
- TeacherAl wants to control
- Bugscope Teamthey are like plates
- 5:05 pm
- Bugscope Teamok al go for it
- Bugscope Teamplates on an armadillo
- TeacherA different line of questioning: what advice can you give these pre-service teachers in using Bugscope or in teaching math and science (K-8)?
- Bugscope Teamannie (al(as alex) is typing a loong answer
- Bugscope Teamthis is on the bumblebee, they have forked setae which is a little different
- Guestwhy are they forked?
Bugscope TeamCate and I were just talking about this--it could be that it helps them to hold onto pollen
- Bugscope TeamBugscope is a really dynamic resource for kids, it allows them to be the "bosses"--rather than experts sitting up at the front of the room and telling them what they think is important, the KIDS get to make the decisions--they get to choose what they learn
- Studentwhat kind of inquiry questions could you start kids out with? Something for them to investigate...
Bugscope TeamUm, well...often the kids just take off and run with it. As soon as they know what they are seeing, they usually have TONS of questions..many which you all asked today
- 5:10 pm
- TeacherPlease let Robyn drive.
- Bugscope Teamgo for it robyn
- Bugscope Teamsuch as what do the hairs do? Where does this insect live? What does this insect eat?
- Bugscope Teamkind of reminds me of a brain (the image)
- Bugscope TeamYou could frame a lesson around something like: what do different insects eat and what do their mouthparts look like
- Bugscope TeamThere tend to be a lot of general insect questions like: what is the most painful sting, do cockroaches transmit diseases, what is the largest insect, what is the smallest insect, what is the most poisonous insect
- Bugscope Teamsometimes they will also ask us how we came to do what we do, or why we like science in general, or if there is a specialty of science we like more
- Studentwhat is the largest insect?
Bugscope TeamThe largest insect the titan beetle, which is a longhorned beetle
- Studenthow big is it
- StudentWhat is the largest cicada?
Bugscope TeamBody is around 4 cm, that is the largest one I have seen anyway
- 5:15 pm
- Bugscope TeamThe heaviest insect is the goliath beetle (a scarab) and the longest insect is probably between the giant weta (which can also be very heavy) and a tropical stick insect species
- TeacherGive Dr. Clishem controls please
- Studenthow heavy?
Bugscope TeamExcess of 100 grams
- Bugscope Teamgiant wetas are a type of katydid, by the way
- TeacherWhich insects sports this lovely stinger?
Bugscope TeamA cicada killer, which is a sphecid wasp
- Bugscope Teamcicada killers are solitary wasps that do as their name implies-- kills cicadas, which isn't the hardest thing to do since they tend to be dumb
- StudentIs it true that the cicada killer paralyzes its victims and lay eggs inside their eyes?
Bugscope TeamI am not sure about the eye thing, but the rest is true
- TeacherWe are going to end with the butterfly wing.
- Studentmulder is hoping to direct his own horror movie some day and he was just getting ideas
Bugscope Teamgood luck
- Bugscope Teamthese are the individual scales
- TeacherLooks like a wicker basket
- 5:20 pm
