- 3:00 pm
- Bugscope TeamJust about ready
- 3:06 pm
- Bugscope TeamThat’s a cute little comb
- Bugscope TeamHi Mrs Fry!
- Bugscope TeamHello Mrs. Fry!
- Bugscope TeamWelcome to Bugscope!
- Bugscope TeamWe're working on/refining the presets
- Bugscope TeamHi there!
- TeacherHi, this is Mrs. Fry. Just checking to make sure we have a connection.
Bugscope TeamLooks like it!
- Bugscope TeamThe star next to your name on the righthand screen lets you know that you have control of the microscope.
- Bugscope TeamHave them log into their own chromebooks
- Bugscope Teamwe can confer control to anyone you suggest. Just one person at a time
- 3:13 pm
- TeacherI've never done this before. Should I have students come up and use my chromebook to control microscope and ask questions or should I have them log in on their own chromebooks.
Bugscope TeamBest if they ask questions from their own chromebooks. That way we can answer them three at a time.
- TeacherOnce they have control, they can click on the magnification, focus, contrast, and brightness using the plus or minus buttons?
Bugscope TeamThey should be able to yes
- 3:20 pm
- Bugscope TeamMrs Fry, we're just finishing up some shortcuts for the students to click on ("presets").
- TeacherI assume there is some delay when they are controlling it, correct? So I should tell them not to continually click a button? Click once and wait?
Bugscope TeamThat's right. Sometimes it takes as long as ten seconds. But if they click click click click, usually something appears "microscope busy" so they'll figure it out.
- Bugscope TeamWelcome to Bugscope, Tanjiro. We'll be ready in just a few minutes.
- 3:27 pm
- Bugscope TeamMrs Fry please let us know when you want us to give a certain student control of the microscope. In the meantime, students are of course welcome to ask questions.
- Bugscope TeamI'm ready to start. Scope is ready. 10, 9, 8,...
- TeacherThey are all beginning to log on right now.
- Bugscope TeamHello Everyone!
- StudentHi :)
- Bugscope TeamThis is the face of a fruitfly
- StudentHello people
- Bugscope TeamHi guys. Mister fruit fly's face welcomes you to Bugscope. Any questions?
- 3:33 pm
- Bugscope Teamits compound eyes are on either side of its head -- the pads we see just inside where the compound eyes are, are part of the antennae
- StudentHi :)
- Bugscope Teamplease let us know when you have questions!
- Bugscope TeamOne of his eyes.
- Bugscope Teamnow we are looking at one of the compound eyes, up closers
- StudentHi, what are those little spikes on the eye?
- Bugscope TeamHi from me as well
- Bugscope Teamthe little spines are setae that let the fly sense wind, and touch
- Bugscope TeamMrs Fry your students are welcome to ask questions.
- Bugscope TeamYay
- StudentWow thats cool
- Studentwhat are the bumps on it's eyes
Bugscope TeamThose are the individual facets of its eyes called ommatidia. The smaller bumps are probably bits of dirt or other stuff that isn’t part of it
- Bugscope TeamWe're fine-tuning the focus for a moment, guys.
- Studentcan the fly feel wind on the rest of its body
- 3:38 pm
- Bugscope TeamOK, done focusing.
- Bugscope TeamThe bumps on the front of its eyes are kind of like the cells on the *backs* of our own eyeballs.
- Bugscope Teaminsects often have thousands of ommatidia making up each compound eye
- Bugscope TeamPlease let us know if someone wants to drive.
- TeacherCan we see the wings of the fly?
- TeacherPlease give Jennifer control.
- StudentWhat were to happen if the setae were to fall off or be ripped off?
Bugscope Teamthat does happen -- they break off. but they have a lot of setae, and it probably doesn't cause too much trouble
Bugscope TeamNot too much, I think. Kind of like shaving the hairs off your arm?
Bugscope TeamFirst of all they won’t grow back. If the insect lives long enough they might come back after a molt. It might just lose some sense of touch
Bugscope TeamThey do not grow back; once an insect has wings it has reached its final form, as an adult
- 3:43 pm
- Bugscope Teamit looks like our software is running slowly right now
- Bugscope Teamso just a second ago we saw an image of the sample
- Bugscope Team-- the whole sample
- TeacherDoes Jennifer have control yet?
Bugscope TeamI see she has it now
- Bugscope Teamnow we're looking a fly's claws, with little setae on them as well. but those setae help the fly stick to ceilings and walls
- Bugscope TeamThis is one claw of the fruit fly. Looks like Jennifer can at least zoom in and out.
- Bugscope Teaminsects and similar arthropods (like rolypolies or ticks or scorpions or spiders) have an exoskeleton -- their skeleton is on the outside of the body, like a shell, or like a knight wearing armor
- StudentWhy are there grooves on the fly?
- StudentWhat are the branches behind the antler looking piece?
Bugscope TeamThose are special setae/hairs that help it to stick to vertical surfaces like windows
- Bugscope Teamso in order to sense what it is in their environment -- what is around them -- they have setae that stick through the exoskeleto
- 3:48 pm
- Bugscope Teamoops 'exoskeleton'
- StudentWhat is the intestinal system in a fly like?
Bugscope TeamMuch simpler than a mammal's. I don't think it even has a separate stomach and intestines.
- Studenthow do fly's mate
Bugscope TeamI am not sure.
- StudentWhat are those 2 holes under the claw?
Bugscope TeamNot sure. I missed it. Sorry!
- Bugscope Teamsome insects, like dragonflies, mate while they are flying
- StudentWhy do flies have claws?
Bugscope TeamAll insects have some sort of claw at the the end of each of their legs that they use to hold onto things
- Studentwhat part of the fly is this
- Bugscope TeamThis is the business end of a tick, what it sticks through your skin.
- Bugscope TeamBecause a dragonfly's head can fall off easily, there are hooks behind the head that secure it when it is mating
- StudentWhat is that bump on the top of the left claw?
Bugscope TeamUm maybe dirt?
Bugscope Team(Sorry, we drove away already.) Probably just a bit of dirt.
Bugscope TeamThe bugs we get here often have crud or pollen or mold or bacteria on them.
- Bugscope TeamThe barbs are what keep it in, like a fishhook.
- Studentcan a fly spread a diseases
Bugscope TeamYes especially mosquitoes
- 3:54 pm
- StudentWhat are the scales we see in the middle of the slide?
Bugscope TeamThere actually is a bit of cut butterfly wing in there, which has scales all over it
- Studentcan we look at the ladybug larva head
- Bugscope TeamEben I'm sure it's different for different flies, but I think most flies mate while they are on a flat surface, not while they are flying
- StudentThere are some diseases that are spread by flies. Can those same diseases kill the fly?
Bugscope TeamThey are not susceptible to those same diseases.
Bugscope TeamNot that I know of. Flies don’t live long enough anyway
- Bugscope TeamHere's the butterfly scale that Marinda asked about.
- StudentWhat would happen if all of the fly's setae fell off?
Bugscope TeamIt would all its senses but sight pretty much. Those setae give it sense of touch and provide chemosensory feedback as well
- TeacherPlease give control to Marinda.
- StudentHow is the wing attached to it's body?
- StudentDoes the butterfly really die if you touch the wing
- 3:59 pm
- StudentWhy are there a lot of holes??
Bugscope TeamI'm not really sure, but that's their shape. The spacing of the ribs determines the color too, sometimes.
Bugscope TeamIt makes them lighter and might help with color shifting
- StudentAre those lines the bones of the wing?
Bugscope TeamThey give the scales structural color
- StudentWhy are the holes in columns?
- TeacherSorry, we have a Marinda and a Miranda. Can Marinda please have control?
Bugscope TeamOops! You have *so* many students :-)
Bugscope TeamOK, mArInda has control. Sorry about that!
- StudentWhat is the size of a butterfly wing?
Bugscope TeamIt’s a couple inches long. I cut out a small snippet off of it
- Bugscope TeamI just asked an expert here, and, yes, the spacing of the holes determines the wing's color and how evenly the color appears from different angles (shimmery, or smooth velvet, or in between).
- StudentWhy are the holes only on the bottom of the wing?
Bugscope TeamThey go all the way through the wing.
- Bugscope TeamThe green box there is Scott fixing the "astigmatism" to make the scope sharper.
- 4:04 pm
- StudentWhat is the size of a butterfly brain?
Bugscope TeamAbout the size of the head of a pin
- TeacherCan we switch to the mantis head and give Gabby control.
- Bugscope TeamSee where it reads "5 microns" below the image, to the left?
- StudentDoes the holes in the butterfly's wing affect its flight
Bugscope TeamI think it just helps make the scales lighter for flight. Maybe it helps with making them hydrophobic as well?
Bugscope TeamThose holes are super small, and the scales themselves are super small. From our perspective without a microscope they are like powder.
Bugscope TeamThe holes are too small to affect flight. A teensy bit of air leaks through them, but not enough to measure.
- StudentDoes the shape of the wing affect how a butterfly flies?
Bugscope TeamThat’s an interesting question and I think they do! There are swallowtail butterflies with those little bits at the end and I think it makes them more fluttery. It would be interesting to see what makes them fly faster or able to change direction better
- Bugscope Teamwe can see that the holes are perhaps a micron across. A micron is one one thousandth of a millimeter
- Bugscope TeamGabby, you have control of the scope now.
- TeacherAre we asking too many questions?
Bugscope TeamI think we are doing okay with the questions
Bugscope TeamNot at all! Fire away. Scott and Cate and I will answer them as we see them.
- Bugscope TeamIf a micron is a thousandth of a millimeter, it is a millionth of a meter.
- Bugscope TeamMantis head coming up.
- Bugscope Teambacteria are often 2 microns (also called micrometers) long. we can see them with this microscope
- 4:09 pm
- Bugscope TeamMantis head!
- Bugscope Teamyou can see one of its raptorial forelimbs to the right
- Bugscope TeamThis mantis looked like a wasp before we sputter coated it with gold-palladium
- Bugscope Teamthe curved part holds its prey against those spines
- StudentWhat's the difference between a grasshopper and a mantis, I've always gotten them mixed up.
Bugscope TeamGrasshoppers are usually green and have those big hind legs
- Bugscope Teamsee the mandibles? they are just above the little stick-like palps, near the mouth
- StudentWhat is in lower right-hand corner of the slide?
Bugscope TeamThat is where one of it’s grabbing arms is
Bugscope TeamLower right is one of his claws, that is closed.
- StudentWhy are the eyes on the mantis so big?
Bugscope Teamit means that they can see all around their head, like a 360 degree view
- Studentwhy are the antennas bent at a 90 degree angle
Bugscope TeamThey were straight when he was alive. Probably just got smooshed in the mail.
Bugscope TeamNot sure. It might have bent that way after it died. Ant antennae do have an elbow bend to them though
- StudentCan you explain the lines on his face
Bugscope TeamNot really... just kind of wrinkly. Sometimes if a bug has dried out for a while that happens, but this guy is fresh because his eyes are still in good shape, not like a deflated soccer ball.
- 4:15 pm
- StudentWhat are the specs on the eye?
Bugscope TeamThis was probably caught in a trap that also caught moths or mosquitoes
- StudentWhat is background behind the mantis
Bugscope TeamIt was given to us by an entomologist student
- Bugscope TeamThe background behind the mantis is double-stick tape. The crater-like appearance is just a side effect of how we cover all the samples with a very thin layer of gold.
- Bugscope TeamHere's a better view of the eye bumps, with a pollen grain sitting on top.
- StudentWhy are the bumps on the eye?
Bugscope TeamThe hexagons are ommatidia again. There is a large thing that is a pollen grain and there’s some other stuff sitting on it too
Bugscope Teameach bump is a facet of the eye, and it functions like an individual eye
- StudentWhat are the things on the eye?
- 4:21 pm
- StudentOr those spikes setae too or something else?
Bugscope Teamyes! they're setae, most likely mechanosensory -- so they would sense touch as well as the movement of wind
- StudentWhy are there scales on the eyes???
Bugscope Teamthe individual ommatidia (the hexagons) are each individual tiny eyes
Bugscope TeamEyelashes isn't too oversimplifying as an explanation. I forget the fancy name!
Bugscope TeamSorry, I think I answered the wrong question... these "scales" are the "facets" or ommatidiae that we've been chatting about already.
- StudentHow does the mantis eat with such small mouth???
- Bugscope Teamyou can tell that there are a few to several thousand ommatidia making up a large insect's compound eye
