- 7:31 am
- Bugscope Teammicroscope is pumping down
- 7:47 am
- Bugscope Teamit's taking its time
- Bugscope Teamclose, now
- 7:55 am
- 8:01 am
- 8:07 am
- 8:16 am
- 8:23 am
- Bugscope Teamwe are making presets, almost done!
- 8:28 am
- Bugscope Teamgood morning!
- Bugscope TeamWelcome to Bugscope!
- Bugscope TeamI'm looking for good diatoms on the waterbug's cuticle.
- Bugscope TeamBut we are ready to roll at any time.
- Teacherwe are just waiting for the students to come
- 8:33 am
- Bugscope Teamthese are mites or crustaceans we have never seen before
- TeacherThat is really cool!
- Teacherwoah! what is that?
- Bugscope Teamyou can see that the diatoms are sometimes, like this one, covered with a lot of juju
- Teachergiant mouth! lol
- 8:38 am
- Studentwhere are we on this bug?
Bugscope Teamnow you can see its proboscis
- Bugscope Teamif this dude bit you it would hurt
- Bugscope Teamthis is the head. it is so big we cannot see all of it at once
- TeacherI dont want to mess with that bug! I dont want to get bitten!
- Bugscope Teamthe eyes -- the compound eyes -- are on either side
- Studenta nickname for him is the eastern toe biter.
Bugscope Teamhaha Perfect!
- Teacherwhat is the tube on top of the proboscis?
Bugscope Teamwe see that on true bugs, and I'm pretty sure it's part of the suction mechanism for slurping up liquid food
- Bugscope Teamwell it's taking forever for the reply from SEM to go through
- Studentgood morning!
Bugscope Teamgood morning!
- Bugscope Teamokay who will be driving today? RMS?
- Teacherwe are all here. lets get started!
- 8:44 am
- Bugscope Teamtrue bugs, which have piercing/sucking mouthparts -- such as cicadas, stinkbugs, etc. -- have them
- Bugscope Teamspider eyes
- Bugscope Teamyou can see lots of setae -- hairs -- among the eyes
- Bugscope Teamspider eyes are often not that sensitive, although some can see quite well
- Bugscope Teamthey do have very sensitive setae
- Studentare their larger eyes more powerful?
- Studentdo you know why they have so many eyes?
- Studenthow are the eyes attached? it looks like they come right out from its body
Bugscope Teamthey are little domes that extend over the cephalothorax
- Bugscope Teamcephalo- is the head, and thorax is the body part to which the legs are attached
- Bugscope Teaminsects have a separate head and thorax but spiders do not
- Teacherwhy do some of the hairs look "spiky" on the sides?
Bugscope Teamthey are 'plumose' setae, like little evergreen trees, very sensitive to vibration
- Bugscope Teamsome spiders have, as well, what are called 'urticating hairs'
- Teacherthe hair on the left looks like a tree/bamboo! lol
Bugscope Teamsure does!
- 8:49 am
- Bugscope Teamthe word 'urticaria' means 'itching'
- Bugscope Teama spider like a tarantula, for example, may release urticating hairs to dissuade a dog from bothering it, as the hairs go up its nose
- Teacheris there like a hole on the center of the hair?
Bugscope Teamit's a place where the dried film we see is not there
- Bugscope Teamthere is some kind of liquid on the spider here -- a dried liquid
- Bugscope Teamsame with the enormous Eastern toe biter
- Studentso in other words thats the acyual hair?
Bugscope Teamthis is a single plumose (referring to the smaller 'branches') seta
- Bugscope TeamI keep calling hairs setae because we're supposed to, but even entomologists give up and call them hair
- Bugscope Teamhere we get an idea that this is live imaging, because you can see that the preset moved from its original position, as shown in the thumbnail image
- Teacherour internet just went down.
Bugscope Teamlooks like you are back!
- Teacherjust got it back up
- Bugscope TeamSweet!
- 8:54 am
- Bugscope TeamYay!
- Bugscope Teamsome web is sticky, and some is not. hard to tell here, though, isn't it?
- Bugscope Teamif a spider got stuck in its own web it could eat its way out; they do recycle their web by eating it sometimes
- Studentyou can see the fractures
- Teacheryummy spiderwebs!
- Bugscope Teamit's good you're not a spider; they are kind of nasty critters
- Bugscope Teamthey inject venom into their prey, and the venom dissolves the internal organs, and then they suck it all up like a milkshake
- Bugscope Teamactually ambush bugs and assassin bugs do the same thing
- Studentid be a faster typer if i where a spider
Bugscope Teamhaha yeah
- Studentare those true bugs?
Bugscope Teamyes they are!
- Teacherwhat are the bumps on the right string?
Bugscope Teamlooks like some dried salts, perhaps, or just debris
- 8:59 am
- Bugscope Teambe sure to cruise to some of the other presets!
- Teacheryummy salt... can I put some on my food?
- Bugscope Teamit would be a pretty small amount. You wouldn't even notice it :)
- Bugscope Teamthis is live imaging of dead specimens in a vacuum chamber, and we are using electrons to collect the images
- Bugscope TeamCate is writing a better response...
- Teacherwhat is the hole-like thing on in the center of the screen currently?
- Bugscope Teamthe only liquid left is dried onto the cuticles of the specimenas
- Bugscope Teamspecimens...
- Teacheris it a cave?
Bugscope Teamit is a place just below that spine in which there was a bubble of some sort
- Studentwhere is the cuticle?
Bugscope Teamif we take the mag down a bit we can see it better
- Bugscope Teamthe dimpled part is cuticle
- Bugscope Teaminsects do not have skin -- instead they have an exoskeleton, which is like a shell or a coat of armor
- Teacherwhat does the cuticle do?
Bugscope Teamit protects the insect from the environment and also gives it support, since there is no endoskeleton
- 9:04 am
- Studentso the cuticle is another phrase for exoskeleton?
Bugscope Teamyes, sorry
- Bugscope Teamnow we see another example of cuticle, which is made of chitin
- Bugscope Teamchitin is a material sort of like our fingernails
- Bugscope Teamthis is a spiracle, which is what insects breathe through
- Bugscope Teamthey have spiracles on either side of each body segment, and they help bring oxygen to the internal organs
- Bugscope Teamon the inside, they are connected to tubes called tracheae
- Teacherwhat is the hole in the ant spiracle?
Bugscope Teamthat is the pore through which the insect breathes, or you could say regulates its respiration, since it can also close the spiracle
- Studentthe defenition of spiracle is?
Bugscope Teamopenings on the exoskeleton that lead to the respiratory system
- 9:09 am
- Teacheris there anything inside the hole?
Bugscope Teamyes there are often hairs in there that are kind of like nose hairs. They keep out particles
- Studentyes there is somthing in the hole.
- Teacherwhat are those hairs?
Bugscope Teamoops Cate just explained it... those serve as a filter to keep particles like pollen out of the tracheae
- Teacherasked too soon... lol
- Studentso spiracles are kind of like gills?
Bugscope Teamyes they are similar in function
- Studentok, neato!
- Teacherso THAT was the bug that we were wondering about!
- Bugscope Teamhere we see the same kind of suction tube we saw on the enormous Eastern toebiter
- Bugscope Teamtrue bugs..
- Studentwow! it looks like there are three sections
- Studentare those the eyes on the sides?
- Studentis it missing a hair in one follicle?
Bugscope Teamit looks that way. Sometimes they can get scraped off
- 9:14 am
- Teacherwhat is the fuzzy like thing?
- Studentwhy does it look like sandpaper?
- Teacherthose look like stones on a pathway
- Bugscope Teamthis looks like a softer part of the cuticle because it is more qrinkly
- Bugscope Teamwrinkly*
- Bugscope Teamthis is actually the closest we get to skin on an insect
- Studentah ok
- Studentwhat makes it softer?
Bugscope Teamit's actually comparable to what the suction tubes we have been seeing are made of
- 9:20 am
- Studentis this from a spider that we sent?
Bugscope Teamyes it is!
- TeacherThat looks... hairy
Bugscope Teamhaha yes and silky, perhaps
- Studentis this all part of the spider's body?
Bugscope Teamthis is external to the spider's body, but note that down below we can see one of its legs, and its claws
- Bugscope Teamspiders often have these comb-like claws
- Bugscope Teamyou see the two larger claws and then smaller 'tines' like a distorted fork
- Teacherinternet went down again...
- Bugscope Teamyou are back, we are happy to see you!
- Studentwe're all back!
- 9:25 am
- Teachermore bamboo! yay!
- Studentif you say so.
- Bugscope Teamthis is about 4 times higher in mag and better resolution than you can see using a light microscope
- Bugscope Teambig bamboo
- Teacherwow! that is really cool!
- Bugscope Teampresently it's 4800x
- Studentwhat is the magnification?
Bugscope Teamyou can see the magnification at the bottom of the image. we are at 4800x!
- Teacherwhat is the bump on the side of the bamboo?
Bugscope Teamlooks to be some dirt
- Teacherit looks like there is a cannon on the left of the bamboo!
- Bugscope Teamthat is one of the 'tines' of the spider's claw; it is a little bit worn
- Studentit was frozen for a bit :)
- Studenttines? like a fork?
Bugscope Teamyes just like a fort
- Bugscope Teamfork
- Teacherfort? like a snowfort? I like snowforts!
- Bugscope Teamhaha. fork sorry
- Studentof topic
- Teacheryes.. it is of topic
- 9:30 am
- Studentoff topic.
- Teachercan you give RMS2 the controls please?
Bugscope Teamthey have control
- StudentI LIKE PIE
- Studentone of our students really enjoys pie :)
- TeacherRMS2 really likes pie...
- Studentplease forgive him.
- Bugscope Teammaybe just this once :)
- Studentok, I am in control now :) and would like to thank you so much for preparing these specimens for us to explore!
- Teacheryeah! thanks!
- Teacherwe can go for about 10 more minutes
- Studentare these thje mandibles
Bugscope Teamyes, in this case they are fangs
- 9:36 am
- Studentthe dog from Harry Potter?
- Bugscope Teamright now this is more like the giant spider in harry potter
- Studentdo you want me to come over there?
- Bugscope Teamwe cannot see the poison pores
- Teacherstay in your seat RMS1
- StudentI have a book.
- TeacherIf you don't, you will get detention...
- Studentok, they are just being silly, no worries, as we changed the picture.
- Studentyour not even the teache
- Studentthis is the last image that we will have time for today.
- Bugscope Teamthis is the tip of the seta from the silverfish
- Bugscope Teamvery interesting setae they have
- Bugscope Teamthe preset was one of the first ones we made this morning, and the specimen drifted a bit in the meantime
- Studentso is this one single hair?
Bugscope Teamyes it is!
- Teacherthat is one big hair~
- Bugscope Teama single seta
- Bugscope Teamlots of the silverfish's setae look like this
- Studenti cant remember the name
- Bugscope Teamthey are weird critters
- Studentit looks like the spike off the tail of a....... dinosaur.
Bugscope Teamit does. like a stegosaurus
- 9:41 am
- Teacherwell, that is all the time we have. Thanks for having us!
- Studentare each of those cone-shaped spikes receptors?
Bugscope Teamwe are not sure if they are mechanosensors, thermosensors, or chemosensors
- Studentwe need to get going now, we are going camping :)
- Bugscope TeamThank You!
- Bugscope TeamCollect some ticks for us!
- TeacherWe hope we can do this again someday!
- StudentThank You!
- Studentthank you!!!!!!!!!!!
- Bugscope Teamhave fun! Thanks for bugscoping with us today!
