- Bugscope Team good morning!
- Bugscope Team welcome to Bugscope!
- Bugscope Team we are setting up now
- Teacher Hi, just checking in to make sure password works and such
Bugscope Team totally cool
- Teacher Thanks...I have a few questions...
Bugscope Team no problem
- Teacher I see I have demag now...did everything go okay when fixing?
Bugscope Team we solved all of the immediate problems, I think
- Bugscope Team we have a more ambitious agenda but those changes will have to wait
- Teacher Great! Also, my students will need the password to log in, correct?
Bugscope Team the system should recognize the IP address of your area, and the students will not need the password
- Bugscope Team also, there should be a Student option when they log in
- Teacher Ok, when they log in, will they be prompted to select a nickname?
Bugscope Team yes
- Teacher These images look great
Bugscope Team cool! Cate is doing all the setup right now
- Teacher Any last minute advice I should tell my students about before hand?
Bugscope Team um do you want us to confer control to them, or do you want to maintain control of the 'scope?
- Bugscope Team we have the ability to give each student control, one at a time
- Teacher I would like them to be able to control for short periods of time...I have 13 students, do you suggest I put them into pairs or do we have enough time to do each individually? I have 45 minutes in class
Bugscope Team it might be less chaotic to have them in pairs
- Teacher Ok, will do, I will have one by herself since the odd number, she will be okay with that
- Teacher I see we have other images besides our samples...will the samples be labeled so the kids know which are ours?
Bugscope Team Cate can do that -- she is saving your samples for last so they show up sooner.
- Teacher ok
- Teacher I cant think of anything else I need them to know before hand...
- Teacher Anything else you need before I sign off?
Bugscope Team no I think we are fine
- Teacher great, see you in a bit
- Bugscope Team We are ready to roll.
- Bugscope Team the spider, the ant, the ladybug, and the fly (the housefly) came from Donovan
- Bugscope Team this right now is the head of the owlet moth
- Bugscope Team hello Abby/Hannah!
- Bugscope Team Welcome to Bugscope!
- Bugscope Team let us know when you have questions, and let us know if you would like to drive the 'scope
- Bugscope Team this is the head of the owlet moth
- Bugscope Team hello Kaleb/Jessica and Andrew/Clayton!
- Bugscope Team hello Everyone!
- Student Hello
- Student hey yo
Bugscope Team yo!
- Bugscope Team hey there
- Student hey
- Student hi
Bugscope Team hello!
- Student Heyy!!
Bugscope Team Heyy LL!
- Student how are you doing
Bugscope Team good!
- Student heyhey!
Bugscope Team Holly!
- Student great meeeee tooo
- Student what are we lookin at?
- Student wait. whos ll?
Bugscope Team Linzie/Laura
- Student this is soooo cool
- Teacher Hello Scot, who are you giving control to first?
Bugscope Team Abby/Hannah have it now
- Student sooo uhh what are we looking at?
Bugscope Team this is the head of an owlet moth
- Bugscope Team Abby and Hannah you should see controls for the 'scope now at the top of the viewing screen. Also, if you click on one of the presets, the 'scope will drive to that place
- Student what's an owlet?
- Teacher the girls do not have controls yet scot, are you loading?
Bugscope Team okay I just gave control to Holly
- Student nevermind
- Bugscope Team Holly can you see controls, or can you click on one of the presets and make it move?
- Student yes
- Student what kind of spider is this?
Bugscope Team the spider you sent is on here, but we are on the moth. The spider we aren't sure what type it is , we were never good at identifying them unless they had some big markers on them like a black widow
- Student i like bugs(:
- Student how do we know if we have control?
Bugscope Team let Holly try it now...
Bugscope Team you will see a simple set of controls on top of the viewing window
- Bugscope Team Cool!
- Bugscope Team Holly is now the Supreme Ruler
- Bugscope Team this is the eye of the housefly you sent
- Student why holly dude?
- Bugscope Team the compound eye, and all of the round things are individual facets called ommatidia
- Teacher ok, we seem to have good control now, holly, move this around, demag, whatever
- Student its a fish!!!!! hahaha im just joshing
Bugscope Team yeah like fish scales
- Student muaha! I feel powerful! what's that on the screen?
Bugscope Team some juju on the fly's compound eye
- Student what is juju?
- Student Is that debris on the eye?
Bugscope Team ha yes
- Student thats weird
- Student hey CLAYTON ima get me some fish eyes to look at
- Student Hiiiiii Holly :D
- Student ok, but why call it juju?
- Student whats the line on the eye?
Bugscope Team oops sorry it's gone
- Student Hi MaryBeth and Css
- Bugscope Team see the pollen grains?
- Bugscope Team the little round dudes?
- Bugscope Team they're spikey
- Student oh pollen cool
- Student whats the furry stuff on the bottom
Bugscope Team those are tenent setae -- they're sticky hairs that let the fly cling to surfaces
- Teacher was this our sample?
Bugscope Team yes!
- Bugscope Team the fly (housefly), the ant, the spider, and the ladybug
- Teacher who brought this in guys?
- Student ?
- Student whats the little hole in it0
Bugscope Team that is where one of the bristle-like setae busted off and fell out
- Student is there a difference between bug hair and human hair?
Bugscope Team yes. bug hair is called setae, and it is often sensory
- Student thats different
- Student uhh definetely not me.. i didnt bring it in. and i bet spiderman has some tenent setae(;
- Teacher scot, is there anyway we can give someone else control now?
Bugscope Team we can
- Student What to look at next?
- Bugscope Team insects have an exoskeleton, which is like wearing armor, and the setae stick through
- Student thats weird
- Bugscope Team you can choose any one of the presets
- Bugscope Team please let us know who would like to drive next
- Teacher holly do you still see controls?
- Teacher who wants to go?
- Student MMMEEEEEE!!
- Student i doo
- Teacher ok, Laura and Linzie
- Student yes. I see the controls.
- Student ahhhhhh
- Student love you mcloving(:
- Teacher just wait a minute Holly, you should not have them in a minute
- Bugscope Team L/L have control now
- Bugscope Team headless fly
- Bugscope Team eeeuw
- Student Bye, controls.
Bugscope Team hey you did a great job!
- Student i like it!!
- Student thanks!
- Bugscope Team the tarsi are folded over the thorax
- Teacher who brought in the fly, I can't remember
- Student their legs are really werid
Bugscope Team yes they have a number of forearm segments that are called tarsi
- Student eew\
- Teacher by do bug legs fold up under them when they die?
- Student what's a thorax?
Bugscope Team the thorax is the core of the body, like our chest/trunk
- Student they dont have bones do they?
Bugscope Team no they have their bones on the outside, like a shell, called an exoskeleton
- Student flys have a trunk?
Bugscope Team insects have a head, thorax, and abdomen
- Bugscope Team and they have six legs
- Bugscope Team so it is not really a trunk
- Student go white sox
Bugscope Team ha
- Teacher landon/dakota absolutely not
- Student !yess ma'ma
- Student otay
- Student what exactly is a fly claw?
Bugscope Team many insects have claws that can open and close like little grasper hands
- Bugscope Team so there are two actual curved claws, and the little fine features are slitcky hairs -- tenent setae
- Teacher scot can we give clayton/andrew control now?
- Student im scared of fruit flys now
Bugscope Team they are mostly just annoying. they can be hard to get rid of once they are in your house. they are attracted to rotting fruit most of all
- Bugscope Team inside the tarsus -- the forearm segment -- is a tendon called an unguitractor that pulls to close the claw and loosens to open it
- Student what is this?
- Bugscope Team this is where the fly's head should been
- Student this just looks naaassstyyy
Bugscope Team it is
- Student what is that?
Bugscope Team that is the 'neck' of the fly
- Bugscope Team Cate put the head directly on the stub. It is over to the right.
- Student is that the headless fly
Bugscope Team yes it came like that. it probably fell off en route to us
- Teacher hey scot
Bugscope Team yes!
- Student thats so gross
Bugscope Team heh sorry
- Teacher can we give clayton/andrew control now?
Bugscope Team okay A/C are the Supreme Rulers now
- Student is it supposed to look like that?
Bugscope Team we don't see the insides that often, but it is not a surprise
- Teacher you guys got controls?
- Student im the best supreme ruler of them all though... so uh yeah
Bugscope Team no problemo
- Bugscope Team this is the spider's head
- Student ooh thats mine
- Student I vote we zoom a little! hah
- Bugscope Team spiders do not have a head/thorax/abdomen; they have a cephalothorax, which is the head and the thorax in one, and they also have an abdomen
- Student haha it looks like a crab!
Bugscope Team yeah it does, good eye
- Student what is the things on its back?
- Student r the bumps the eyes?
Bugscope Team yes they are!
- Bugscope Team now we see the pedipalps
- Teacher wheres its eyes?
Bugscope Team you cant see them too well but they are on the front part of the "shell", a little north from here
- Teacher and what is on it?
- Bugscope Team they're like boxing gloves, and this is a male spider, pretty sure, from the larger palps/pedipalps
- Student What r Pedipalps?
Bugscope Team they're like accessory mouthparts, or the 9th and 10th leg
- Student spiders can box?
- Student you spelled SPIDER wrong
- Student sipder*
- Student spider**
- Teacher I hate to rush, but can we have cassidy and mary beth take over now?
Bugscope Team got it!
- Student what do they do for the spiter?
Bugscope Team the male spider fertilizes the female using the palps
Bugscope Team and then he gets out of the way so he doesn't get eaten
- Student whats that?
Bugscope Team this is a beetle head
- Bugscope Team small beetle
- Bugscope Team you can see the clubbed/lamellated antennae
- Student loving relationship(the woman tries to eat him)
Bugscope Team yeah praying mantises are like that too
- Teacher so how much time does he have to get away
Bugscope Team it depends, of course, in part on whether the female is hungry
- Student ahaha ewwh! his baby's mom will eat him?
Bugscope Team yeah....
- Student That beetle has some massive pores..
Bugscope Team heh
- Bugscope Team male spiders, depending on the species, can be much smaller
- Bugscope Team the females are just trying to get enough energy to lay eggs
Bugscope Team yeah, thinking ahead. you're done, Dude, now I'm hungry
- Bugscope Team you can see sensilla on the short limb here
- Student how small can they get?
Bugscope Team they can be super tiny compared to the female
- Student man im hungry too!
Bugscope Team haha
- Teacher scot can we have abby and hannah now please?
Bugscope Team done
- Student why are the pictures black and white?
Bugscope Team when we use electrons to get what are called secondary electrons to eject from the sample, the secondary electrons are collected in a detector as signal. there is no color, just intensity of signal
- Bugscope Team but the samples are no longer colored anyway, not on the surface we see. because Cate coated them with gold/palladium, which is silver
- Student what is this?
- Student what is that
Bugscope Team we are looking at tenent setae on the forearm (tarsus) of the ladybug. which seems to have lost its claws
- Student silver to help with the magnification??
Bugscope Team the gold/palladium looks silver because palladium is silver. But we also put silver paint down to help the electrons run to ground
- Teacher why do they have to be gold/palladium coated?
Bugscope Team the Au/Pd makes the samples conductive so that the electrons do not just go into them and make them charge up
- Student where is this hair located? the legs?
Bugscope Team this is on the legs, yes
Bugscope Team if you take the mag down you can see where you are
- Teacher sorry ladies, could we have dakota and landon now?
- Student so lady bugs have hair?
Bugscope Team yes but we are not supposed to call it hair because what defines and distinguishes mammals is that they have hair
- Student do all bugs have hair on their legs or something?
Bugscope Team yes many insects have varieties of what looks like hair
- Student Thats a bad idea Mrs. McAuliffe lol jk
Bugscope Team nevertheless Dakota and Landon now have control
- Teacher no some shave
Bugscope Team if they did they would lose the ability to sense their environment
- Bugscope Team so Dakota and Landon you can now drive, you know
- Bugscope Team this is how insects breathe
- Student eew
- Student i shave my legs.. i lost all ability to sense my enviroment
Bugscope Team ha but you have nerve endings in your skin
- Teacher whats a spiracle?
Bugscope Team it is an opening that is connected to tracheae inside the body that carry air/oxygen
- Student i got my eyeballs to sense my enviroment
Bugscope Team you also have your nose to smell the air and nerve endings in your skin to sense touch, hot/cold
- Teacher but bugs dont actually have lungs do they?
Bugscope Team not really. it is good that they are inefficient breathers; if they could breathe better they could be larger, and that would be frightening to us
- Student it looks like a feather on a pillow on a blanket on a couch
- Student whats coming out of his eye
Bugscope Team the thing that looks like an eye is called the pedicel, and it is the base of the antenna
- Student Im not Scared of no bug!!!
Bugscope Team but if they were like really big it might not be so pleasant
- Student hahahaha CLAYTON
- Teacher how about giant dragon flys during the triassic period?
Bugscope Team there was more oxygen in the atmosphere and insects could be larger
- Bugscope Team insects were bigger than because there was more oxygen in the air
- Student Well im kind of scared of spiders.. Especially the big, black, hairy ones lol
- Student (:(:
- Student wait. clayton your scared of spiders haha
Bugscope Team spiders inject venom into their prey, the venom dissolves the insides of the prey, and then they suck it all up like a milkshake
- Student giant bugs = unhappy me... so thank you, lack of oxygen!
Bugscope Team exactically
- Bugscope Team assassin bugs and ambush bugs do the same kind of thing as spiders regarding table manners
- Student i have table manners
- Student no...you dont
- Student so if we gave a spider more oxygen it would grow?
Bugscope Team yeah I think if you gave them an atmosphere higher in oxygen they would be able to take advantage of that and become larger
- Student wow thats scary to know!!
- Student ewww
- Bugscope Team spiders can jettison limbs at will, also. if they sense that a toxin has entered one of their legs they can just let it go
- Student a untasteful milkshake
- Bugscope Team here we can see that at least from this view the beetle is unlikely to be able to climb. oops gone...
- Bugscope Team this is a spiracle, but an odd one
- Student and then they will grow it back right?
Bugscope Team if they are the kind of spiders that live long enough to molt
- Student it looks like Hooks... hook from peterpan
Bugscope Team that's right!
- Student thanks, guys!
- Student thank u!
- Student THANKS CATE AND SCOT
- Student THAAANNNNKKKKSSSSSSSSSS
