- Bugscope Teamstarting presets
- 8:19 am
- 8:27 am
- 8:33 am
- 8:39 am
- Bugscope Teamdone with presets, session unlocked, we are ready
- 8:47 am
- Bugscope Teamhello ldob
- Guesthi, we are previewing, we are on for tomorrow at rockford lutheran
- Bugscope Teamcool!
- Bugscope Teamwelcome to bugscope
- Bugscope Teamwe are waiting for the teacher for today's session to login
- Bugscope Teamoh cool. BTW we have the samples you sent us
- Bugscope Teamafter the session is over, if you are still around, we can give you control of the scope so you can practice for a few minutes
- Bugscope Teamthis is a large spider, and Cate left it, after doing the presets, so we could see the fangs
- Guestwe are going to go read about the scope and come back a little later
- Bugscope Teamokie dokie
- Bugscope Teamwelcome to bugscope!
- Bugscope Teamhello ms tiffany :)
- Bugscope Teamms. tiffany, we are ready for you and your students anytime, if you have any questions please just ask us
- 8:55 am
- Teacherdoes this spider bite?
Bugscope Teamyes we think it is a grass spider, and Scott says he's been bit before
- Bugscope TeamMs Tiffany you may try driving anytime you would like. You can also choose from among the presets to select another insect or a different view of a sample
- Bugscope Teamyes you can see its fangs
- Teachercan you tell if this a boy or girl spider?
- Bugscope Teamthey make big dome-like bumps on your skin, or at least they did for me
- Bugscope Teamit is hard to tell but from the size of the palps, of which one is left, on the left, it looks like a boy
- Teacherdoes it bite with the fangs we are looking at?
- Bugscope Teampreset no. 14 will take you to the fangs as well
- Teacherwhat is this picture we are looking at?
Bugscope Teamwe are near the spider spinnerets (which we can't see). The cool thing about spiders is they have plumose setae (setae are insect hairs) that are different from most other insect hairs
- Bugscope Teamthe setae we see here are called 'plumose' setae because of their 3 dimensional shape, like a christmas tree
- Bugscope TeamThey are probably helpful in detecting vibration
- 9:00 am
- Bugscope TeamMs Tiffany these are not just pictures -- you can drive the microscope
- Bugscope Teamwhen you select a preset the microscope drives to that position
- Bugscope Teamcool
- Teacherwhat is all the hair on the spider for?
Bugscope Teamspiders in particular, and as Cate said, need to be very sensitive to vibration, and many of the hairs (setae) are mechanoreceptors that transmit noise/vibration signals to the spider's brain
- Teacherhow many eyes do spiders have?
Bugscope Teamthey have 8 eyes, just like the number of legs on a spider
- Bugscope Teamspiders have the ability to make a particular leg fall off if they, for example, detect venom moving into that leg. it prevents the venom from entering the body -- the cephalothorax
- 9:05 am
- Bugscope Teamwhen they jettison a leg, that is called autotomy
- Teacherdoes the leg grow back
Bugscope Teamyes it can when they next molt.
- Teacherwhat does this kind of spider eat?
Bugscope Teammost spiders are predatory, feeding on other insects or other spiders too... yum!
- Bugscope Teamback there a second ago you could see the little toothlike elements the spider uses to hold its prey with its fangs
- Teacherdoes this spider build a web
Bugscope Teamthis kind of spider, if we have it identified correctly, builds a funnel-like web in the grass
- 9:10 am
- Bugscope Teamthe funnel-like web may not be sticky
- Bugscope TeamAnnie!
- Bugscope TeamHello!!
- Bugscope TeamAnnie is our entomologist, but she also knows about lots of other critters, like spiders
- Teacherwhy is this called a stink bug?
Bugscope TeamA stink bug releases a smelly liquid from glands on it abdomen when it is disturbed. The smell is usually kind of like rotten fruit.
- Bugscope TeamIt is pretty stinky
- Teacherhow many legs does a stink bug have?
Bugscope Teamthey have 6 legs
- Teacherwhat does a stink bug eat?
Bugscope TeamStinky bugs either feed on plant and fruit juices. Some are predatory and they feed on other insects.
- 9:16 am
- Teacherwhere do they live?
Bugscope TeamThey live in many different natural habitats. They live all over the world, except in very cold places.
- Bugscope TeamI found a stink bug on the outside of my front screen door this summer, and I was looking at it from the inside. When I got too close, it started to excrete a droplet of smelly liquid
- 9:21 am
- Bugscope Teamthis is such a cool-looking fly
- Teacherdoes a fly really poop everytime it lands
Bugscope TeamNot every single time...only when it has to "go"
- Bugscope TeamYou can usually see fly poop--it is a small brown speck of dirt
- Bugscope Teamflyspeck
- Bugscope Teamdepends on the type of fly of course....mosquito poop is usually sort of liquidy
- Bugscope Teamand some flies don't eat as adults, so they don't poop at all
- Bugscope Teamentomologists call poop "frass"
- Bugscope Teamthis is a tgreat view of the compound eye of the fly, and to the left you can see one of its antennae
- 9:26 am
- Bugscope Teamfly's often have HUGE compound eyes - like this one does
- Bugscope Teamthe compound eye has hundreds to thousands of facets -- little lenses -- called ommatidia
- Bugscope Teamone way compound eyes are different from our eyes is that they are much more sensitive to movement; insects with complex compound eyes like that see changes in the space around them very quickly, and they can then respond more quickly
- Teacherthank y ou for allowing us to look at these bugs but my four year olds are loosing interest
- Bugscope Teamit makes it hard to catch them
- Teacherthank you again
- Bugscope Teamno problem -- Thank You for logginb in today!]
- Bugscope TeamThank you!
- Bugscope Teamthanks for using bugscope today, i hope they learned a lot :)
- Bugscope Teamms tiffany, all the chat and images are available anytime at:
- Bugscope Teamhttp://bugscope.beckman.uiuc.edu/members/2008-121
- 9:31 am
- Bugscope Teamthat web page is available to you and your students to review anytime, so you can study your session materials after the session is over
- Bugscope Teamthe link to your member page is also included in the original email we sent to you after you applied to bugscope
- Bugscope Teamok, ldob, you have control of the scope now
- Bugscope Teamldob we have given you control of the microscope if you would like to test
- Bugscope Teamyou should see controls on your right of the image, magnify, nav, focus and adjust
- Bugscope Teambeetle face
- Bugscope Teamyou can see a couple of palps
- Bugscope Teammandibular and maxillary palps
- Bugscope Teampalps are used to manipulate/taste food
- Bugscope Teamand the tips of the jaws, I think, here
- 9:36 am
- Guestthis is tricky
Bugscope Teamyou get used to it after a while. we've made the controls a lot like it is controlling the real ESEM, for a more realistic experience
- Bugscope Teamlots of dirt and lots of sensory setae
- Bugscope Teamyou seem to be doing well
- Bugscope Teamif you want real fine control of navigation, i suggest you use "click to center" instead of click to drive
- Bugscope Teamyou might have to take the mag down to see where you are
- Bugscope Teambe sure and try a preset, if you have time; we have plenty of time
- Bugscope Teamyeah, make sure to use the magnify. often it's easier to find what you are looking for by first lowering the mag, then moving, then increase mag to focus in on what you want to see
- Bugscope Teamthe images you collect will go to Ms Tiffany's page, and she will be able to access them later, as could you if you wanted to look in on her session later
- Bugscope Teamyes, and when you have your session, all your chat and images will be saved to your own member page
- 9:42 am
- GuestThanks, I will see you tomorrow.
- Bugscope Teamok, see you tomorrow!
- Bugscope Teamcool Thank You!
- Bugscope Teamsee you tomorrow:)
- Bugscope Teamnice session everyone. rxl stopped, session disabled, session locked. bye bye!
