- 9:50 am
- Bugscope TeamGood morning!
- Bugscope Teamhello Elms!
- Bugscope TeamWelcome to Bugscope!
- Teacherwelcome, we are here with a fifth grade class
- Bugscope TeamYou have control of the microscope. Please let us know if you have any trouble driving, and please let us know when you have questions about anything!
- Teacherwhat insect and part are we focused on
Bugscope Teamthis is the claw of an earwig
- Bugscope Teamwe have some of your insects along with some of ours today
- Teacherhow do I move it
- Bugscope Teamit has a mite on it
- Bugscope Teamyou should see controls to the right of the image
- Bugscope Teamthe session was locked, I just unlocked it
- Bugscope Teamyou can change the mag, select click to center to enable you to use the mouse on the screen and click off center - whereupon the image will recenter
- Bugscope Teamif you use click to drive, remember to click to stop
- Bugscope Teamand you can click on any of the presets to have the microscope drive to that saved location
- Bugscope Teamthe presets are the thumbnail-sized images to the right of the chat box
- Bugscope Teampresets are places we have chosen beforehand that you will be taken to and can then drive around
- 9:55 am
- Bugscope Teamright now we are seeing carbon double-stick tape that the insects/arthropods are all mounted upon
- Teacherhaving trouble navigating could you select the part
- Bugscope Teamso I just clicked on preset #13 -- the flea head
- Bugscope Teamif you get lost, it could help to single click on a preset in the lower right, and the microscope will navigate you there
- Bugscope Teamyou can see the eyespot -- the eye
- Bugscope Teamnow we are back on the earwig claw
- Bugscope Teamyou can scroll through the presets
- Teacherwhere is the mite
Bugscope Teamthe mite is found on another leg, you could try driving to the left and taking down the mag to find it, or you could clickon preset 11 to go right there
- Bugscope Teamsometimes it is better to click F11 to expand your screen to the full size
- Bugscope Teamthe mite is preset 11
- Bugscope Teamthere it is!
- Bugscope Teamcan you scroll down to see other presets? sometimes it is hard to see them depending on what you are using to control the 'scope
- 10:00 am
- Bugscope Teamto us it looks like you are clicking on the same preset each time, and it keeps going to that
- Bugscope TeamI just clicked on preset 5
- TeacherI just found the scroll the area, thanks
- Bugscope Teamtotally cool
- Bugscope Teamthis is not easy to do first time, we know!
- TeacherIs this the beetle?
Bugscope Teamyes this is the beetle!
- Bugscope Teamsee the large compound eyes on either side of the mouthparts?
- Bugscope Teamyay! The beetle!
- TeacherI found this boring in a mesquite,
Bugscope Teamcool!
- Bugscope Teamnow we see its mouth, and we see its palps, which are like arms that belong to the mouth, and we see the antennae, and we see the eyes on either side of the head
- Bugscope Teamthese are little pores that we find above each set of legs
- Teacherwhat is the spiracle
- 10:05 am
- Bugscope Teama spiracle is what insects use to breathe through, and although this is not an insect, it is a similar structure
- Bugscope Teamthis is the millipede's head, tucked into a ball with its body
- Bugscope Teamthe legs are all the same shape, and they have a single claw, sort of like a sharp toenail
- Bugscope Teamtwo different shapes of moth scales!
- Bugscope Teamsome are jagged and some have a rounded top edge
- Bugscope Teamyou can see that the moth is covered with scales, even down its arms
- Bugscope Teamthese are ommatidia -- the individual facets of the eye
- Bugscope Teamand this is salt from a Wendy's restaurant
- Bugscope Teamif you take the mag down here you can see where you are
- 10:10 am
- Bugscope Teamthe tongue of the wasp!
- Bugscope Teamclaw!
- Bugscope Teamhamuli!
- Bugscope Teamdo you want to know what they do?
- Bugscope Teamnow if you take the mag down you can see where this is
- TeacherI just changed classes, now 4th grade will be comming in
- Bugscope Teamthis is very good -- we rarely get such a good view of the tongue
- Bugscope Teamcool!
- TeacherI am taking some time to learn to navigate, my students really enjoyed the 'tour'
- 10:15 am
- Bugscope Teamgreat!
- Bugscope Teamwe often make presets so that the students will be curious about the context -- about where they are
- Bugscope Teamsee how the compound eyes are very round and streamlined into the shape of the head?
- 10:20 am
- Bugscope Teamlook at all of the pollen!
- Teacherwhat are the small bumps
Bugscope Teameach one of those are a ball of pollen
- Bugscope Teamthose are pollen grains!
- Teacherwhat are the pointed things
- Bugscope Teamtheses are the parts of the antenna that help the wasp taste the air
- Teacherstundents say ewwwwwwww
- Bugscope Teamthe pointed things are setae that likely give the wasp information about how the wind is moving
- Bugscope Teamif you take the mag down you can see sort of where you are
- Bugscope Teamthis is cool too!
- Bugscope Teamthese are a very few of the eye facets of the moth
- Bugscope Teamthey look like almost perfect hexagons
- Bugscope Teamthe moth may have thousands of ommatidia in each compound eye
- Bugscope Teamthis is a claw, and in the center is a part called an 'arolium'
- Bugscope Teamwe like to get kids grosses out doing this. Makes the whole experience that much more fun
- Bugscope Teamthe ariolium can swell and shrink and help the moth grasp or cling to a surface
- 10:26 am
- Teacherwell, we are from Texas and it is hard to gross us out
Bugscope Teamyeah I bet. You have a much more diverse collection of insects there then here for sure
- Teacherour students think its cool
- Teacherwe live in a semi desert area, our insects have wonderful adaptations
- Bugscope Teamthat is pretty cool
- Bugscope Teamhere
- Bugscope Teamhere's the mite
- Bugscope Teammites like this often live on earwigs
- Teacheris it a parasite or is it a sybiotic relationship
- 10:31 am
- Bugscope Teamwe are not sure; these are not well studied
- Bugscope Teamwe find the (apparently) same mites on other insects, sometimes
- TeacherI have a hissing cockroach that has a mite that lives with it , are they similar
- Bugscope Teamcould be!
- Bugscope Teamwe have seen these mites on large millipedes, and we think they come from the soil
- Bugscope Teamthe flea!
- Teacheris the circlular part an eye
Bugscope Teamyes!
- Bugscope Teamit has cutting mouthparts that would be to the left just out of where we are focused now
- Teacherwhat is the fiberous stuff
Bugscope Teamit was stuck to the insect. I think it might be lint of some sort
- Bugscope Teamyes it looks like plant fibers to us
- Teacheris this what they are protecting when they coil up in a circle
- 10:37 am
- Bugscope Teamthis is something we have found recently, and we are not really sure whether it is a spiracle or a venom duct, or just what it is
- Bugscope Teamwhen they curl up, their backs are probably tougher than the rest of them. It protects their heads and limbs
- Bugscope Teamsee the mandibles here, in the middle on top?
- Bugscope Teaminsect mouthparts are quite different from ours in several ways
- Bugscope Teamone is that their mouths open from side to side
- Bugscope Teamand they have accessory limbs that help them eat and taste their food
- Teacherthe beetle head isnt coming up
- Bugscope Teamthose accessory limbs are called 'palps' or sometimes 'pedipalps'
- Bugscope Teamhit refresh on your browser
- Bugscope Teamtry refreshing your screen
- Bugscope Teamyour browser window that is
- Bugscope Teamdo you see it now?
- Teacherthanks it is up now
- Bugscope Teamthe little bumpy things on the side of the head are the compound eyes
- 10:42 am
- Bugscope Teamand there are four palps, as well as the two antennae on the left and right
- Bugscope Teamthis is the lower portion of the mouth
- Bugscope Teamthe claw!
- Bugscope Teamthe setae we see -- the little bristles or hairs -- are often mechanosensory. they help the insect sense its surroundings through the cuticle, which is what the exoskeleton is called
- Bugscope Teamif you had an exoskeleton it would be like wearing a suit of armor all of the time
- Teacherwhat part is this
Bugscope Teamthis is part of the mosquito eye. They are normally more plump then this. When insects die, they dry out a bit, creating a sunken look with their eyes sometimes
- 10:47 am
- Bugscope Teamthe ommatidia are littered with scales
- Bugscope Teammosquitos, silverfish, and moths and butterflies have scales, as well as very few beetles
- Bugscope Teamlooks like we are off the stage
- Bugscope Teameverything we are looking at is in a vacuum chamber
- Bugscope Teamand all of the critters on the stub are coated with a few nanometers of gold-palladium alloy to make them conductive
- Bugscope Teamthe last four or five segments of the limb are called the 'tarsi.'
- Teacherour time is up. this has been great, thanks for the time
- 10:53 am
