- 8:41 am
- Bugscope Teamwe'll have to ask Annie to check them out
- Bugscope TeamI am having weird things happen with my controller and closed the setup page...
- Bugscope Teamhello mrs. sagler! welcome to bugscope.
- Bugscope TeamWelcome to Bugscope!
- Bugscope TeamWe have been driving around, checking out this shield bug.
- TeacherGood morning all - this is the class that high point is running for us
- 8:46 am
- Bugscope TeamGreat!
- Bugscope Teamexcellent, we are ready for you anytime. you should see controls on the top right of your browser
- Bugscope Teamand presets on your bottom right
- TeacherThis is Doug Geiwitz and I am just getting things checked over before the class starts
- Bugscope Teamoh yeah, hi doug, we met on a previous session i think.
- Bugscope TeamShield bugs are related to stink bugs and are sometimes the same thing. They produce a foul-smelling liquid and we were looking for the places that might come from.
- Bugscope Teamthat may be what presets 10 and 11 represent.
- Teacheri will start things off then pass them over to the kids
- Bugscope TeamGreat!
- Bugscope Teamsounds good
- 8:52 am
- Teachermy name is lili what bug is this
Bugscope Teamthis is a shield bug, similar to a stink bug
- Teachermy name is sara is this the head?
- Bugscope Teamhi sara, yes this is the head
- Bugscope Teamthe eyes are on the side of the face, look like half circles
- Bugscope Teamyep, this is the head of the shield bug, and you can see the compound eyes on it too, try zooming in to get a better look
- Bugscope Teamyeah, there ya go
- Bugscope Teamthe antennae are just above the eye
- Bugscope Teamcompound eyes are very cool. they are made up of hundreds of individual facets (ommatidia), each of which has a lens in it.
- Bugscope Teamthe eye is a compound eye, meaning it has many facets called ommatidia that capture an image
- Bugscope Teamyou are doing a great job so far, let us know if you are having any problems
- Bugscope Teamthe difference with the ommatidia is that the lens can't move, it's stuck in the direction it is looking, that is why the compound eye has so many ommatidia, that way it can see a wide angle.
- Bugscope Teamthe ommatidia are little lenses -- we can tell when we see a broken eye, occasionally. They are crystalline.
- Bugscope Teamhi all
- 8:57 am
- Bugscope TeamHi folks
- Teachermy name is delaney do thay have exoselten
Bugscope Teamyep, insects have an exoskeleton which protects them from the harsh environment.
- Bugscope TeamAnnie we found these cool little organelles on the body of the shield bug -- see preset 11
- Bugscope Teamyes the shield bug has an exoskeleton.
- Bugscope TeamI see those--they could be scent glands
- Bugscope TeamI am not sure
- Bugscope Teamit is made of chitin and similar to what our fingernails are made of.
- Bugscope TeamI am not sure what these are!
- Bugscope Teamit is also called cuticle
- Teachermy name isevan howoldis it
Bugscope TeamThis insect is probably one year old. They live one summer, usually
- Bugscope Teamthis is probably less than a year old -- I don't think they last over the winter
- 9:03 am
- Teachermy name is lili is the bug olive
- Bugscope TeamLili this one was kind of pale yellow.
- Bugscope Teama sturdy looking bug, and actually it is a bug -- a true bug
- Teachershe means alive
Bugscope Teamno it is not alive
- Bugscope Teamoops sorry none of the critters in the 'scope now are alive.
- Bugscope Teamit wouldnt be able to live in the microscope if it were alive. plus it would be hard to look at if it moved around a lot
- Bugscope Teamwe don't kill them, usually; people give them to us after they have died
- Bugscope Teamit would have to hold its breath for a long time because there is a vacuum in the specimen chamber
- Teacherhi my name is bryanna how many legs are on this bug
Bugscope TeamAll adult insects have 6 legs
- Bugscope Teamwe are beaming electrons at the samples, and the images we see come from electrons that bounce out of the conductive coat of gold-palladium we have put on the samples
- Bugscope Teamso this shield bug is an adult, and it has six legs
- Bugscope Teamyou can see one of the antennae in the middle of the image, and you can see the bug's proboscis on the left, or you could a second ago...
- Bugscope Teamthe bug really is shaped like a shield
- Bugscope Teamthe proboscis is a mouth part that is like a straw
- Bugscope Teamit is on its back so we can see its legs
- 9:08 am
- Bugscope Teammany of these bugs feed on plants and push their proboscis into the plant so they can suck juices out.
- Bugscope TeamThey eat an entirely liquid diet
- Teachermy name is coral dous it hurt the bugs eyes with drit on the eyes
Bugscope TeamWhen insects are alive, they will clean dirt and goo from their eyes. I am not sure if it hurts them though. We don't know much about insect pain
- Bugscope Teambe sure to try some of the other presets if you would like to see some other insects
- Bugscope Teamspiders usually have 8 eyes
- Bugscope Teamyou can see they are all grouped together ehre
- Bugscope Teamthey can use their arms to wipe dirt away from their eyes. It probably does not hurt them; they can only feel if they have something there to transmit the feeling to nerves
- Bugscope Teamthese are spider eyes
- Bugscope Teamok, mrs. sagler 2, i just switched control to you
- Bugscope Teamthings should be okay now
- Studentsorr, we had a little problem on our end and we are back now
- Bugscope Teamno problemo
- Bugscope Teamthe spider here is on its belly
- Bugscope Teamnotice how hairy the insects are. those hairs are called "setae", a single hair is called a seta. setae help the insect to sense it's environment.
- 9:15 am
- Studentmy name is will what kind of spider is it
Bugscope Teami dont know if we know what kind of spider this is
- Bugscope Teamif you zoom in on on of the seta, you will see how it comes out of the exoskeleton.
- Bugscope Teamits not very big. you can see the scale bar in the bottom right hand corner of the screen for 1mm
- Studentmy name is nick how long is this spider
- Bugscope Teamit is about 5mm big according to the scalebar in the bottom right hand corner
- Bugscope Teamhi nick, like cate said, check out the scale in the bottom left of the image, it says 1mm, that means one millimeter. so the spider is about 3-4 millimeters long i think
- Bugscope Teamyou are actually controlling the microscope live! the microscope is called an ESEM (environmental scanning electron microscope). it costs $600,000, but don't let that scare you.
- 9:20 am
- Bugscope Teamthis is an ant mouth
- Bugscope Teamwe are looking at it from the underside
- Bugscope Teamthis is a flying ant
- Bugscope Teamwe have noticed that ants almost alway look like they have another insect in their mouths, but it is just that they have very busy mouths...
- Bugscope Teamlots of little palps to help them taste what they might be eating
- Bugscope Teammrs sagler, all of the chat and images from this session are saved onto your member page, so you and your students can study the information later: http://bugscope.beckman.uiuc.edu/memebers/2008-011
- Bugscope Teamyou can see that the antenna on this side, at least, is broken off
- Bugscope Teamsorry the link is: http://bugscope.beckman.uiuc.edu/members/2008-011
- Studentmy name is evan how much dose it wae
Bugscope TeamMuch less than an ounce...maybe 0.1 oz? Just an estimate.
- Bugscope Teamthis probably weighs a hundred milligrams or so
- Bugscope Teamvery small and light
- Studentmy name is dustin is it a boy or a girl
Bugscope TeamThis is a female ant, most likely. Most of the ants that you see are girls
- 9:25 am
- Bugscope TeamI was thinking about a 10th of a gram
- Bugscope Teamor less than a grain of rice
- Bugscope TeamGram...yes. I am all mixed up on units of weight
- Bugscope TeamI think it is a boy
- Bugscope Teamnow you can see its wings
- Bugscope Teamnice driving the scope, now you can see the wings of the ant!
- Bugscope Teamants and wasps are both related
- Bugscope Teamoops I thought the opposite
- Bugscope TeamI was wrong on how much the ants weighs...it all evens out in the end
- Bugscope Teamthat is nice of you to say Annie
- 9:30 am
- Studenthi my name is mara where do you find all these bugs
Bugscope TeamSometimes teachers and students send is samples. Sometimes we collect them ourselves
- Bugscope TeamIt's true
- Bugscope TeamMara we have been doing this for awhile, and people often send us bugs when they find them. We also collect them ourselves, sometimes. And Annie can get them from old collections for us.
- Bugscope TeamAnnie is an entomologist.
- Bugscope TeamThat I am
- Bugscope TeamSo she studies insects.
- Bugscope TeamAnnie rustles long-horned beetles.
- Bugscope TeamNot during the winter though...there are not too many to rustle
- Bugscope Teamnow you can see the individual facets of another compound eye
- Studenthi my name is becca how long is the wing
- Bugscope TeamBecca the wing is about 7 or 8 millimeters long.
- 9:35 am
- Bugscope Teamthis is a big housefly
- Bugscope Teamthose very small holes in either side of the abdomen are spiracles
- Bugscope TeamSpiracles are like nostrils
- Bugscope Teaminsects breathe through their spiracles
- Studentmy name is logan how fast is a fly
- Bugscope Teamit looks like there is also a haltere in this view of the fly
- Bugscope TeamLogan that is something we will have to look up!
- 9:41 am
- Bugscope Teamhere you can see spines on the fly's legs
- Bugscope Teamwell they fly faster than you can swat them with a flyswatter!
- Studentnick how many germes are their on the fly
Bugscope TeamIt is hard to say exactly how many germs are on a fly. It depends where the fly has been hanging out. A kitchen is less germy than a port-a-pot
- Bugscope Teamhorse flies are fast, dragonflies are very fast (like 36 mph), and houseflies are about 8 km/h
- Studentcan we see germs on the fly
- Bugscope Teamwe can see germs, as bacteria, when they are there
- 9:46 am
- Bugscope Teambacteria such as E coli or even anthrax are bacilli, and they are usually about 2 micrometers (microns) long
- Bugscope Teama micrometer, or micron, is one one thousandth of a millimeter
- Bugscope Teamyou can see how long a millimeter is in this view of the housefly
- Bugscope Teamthis is probably a female housefly
- Bugscope TeamHouse flies are not major carriers of disease, well not in the US anyway
- Studentdo they have an autak
- Bugscope Teammale housefly eyes are usually close together
- Studentattack
- Bugscope TeamI am not sure I understand the question...
- Bugscope Teamheh, i thik all insects of some attack in the sense that they do need to feed and certain parts of their bodies are adapted to help them feed better.
- Bugscope TeamDo you mean do they attack people? It seems like they really do like to bite when it is about to rain...
- Bugscope Teamthis is the end of someone's hair
- Bugscope Teamhuman hair
- Bugscope Teamand this is the shaft of the hair
- Bugscope TeamTrue house flies: Musca domestica do not bite. They can't bite. They don't have any biting mouthparts
- Bugscope Teamthis is from a guy who was concerned that some of his hair was starting to turn white, and he wanted us to look at it.
- Studentcoral : do bugs get sick
Bugscope Teamyes! There are many diseases that make insects sick. Viruses, bacteria, fungi, nematodes, all make insects sick.
- Bugscope TeamLots of my hair is turning white!
- 9:51 am
- Bugscope Teamyes insects can get sick
- Bugscope Teamsometimes they get fungal diseases, for example
- Bugscope Teamsometimes the fungus gets them to do odd things
- Bugscope TeamInsects don't have as good an immune system as we do, and usually insects don't get well from their illnesses
- Bugscope Teami wonder if flys eat more chicken noodle soup when they are sick?
- Bugscope Teambugs can sometimes carry disease too then they are called vectors
- Studentbryanna : how many hairs does a fly have
Bugscope Teamthousands! the hairs are called setae (sea-tea), and they help the fly to sense it's enviornment. the setae are on the body, the eyes, the wings, all over.
- Bugscope TeamBryanna there are almost too many hairs to count.
- Bugscope Teamthe hairs are called 'setae.'
- Studentsara:can you put your hand under the microscope and see it?
Bugscope Teamsara, this microscope is actually a vacuum, meaning it's a lot like space (the air is removed), so no, you'd have to cut your hand off to put it in there, and we don't want to do that!
- Bugscope Teamnot in this microscope
- Bugscope Teamsome of the setae (pronounced see-tee) help the fly smell
- Bugscope Teamthis microscope has a vacuum chamber, so we cannot open it when it is running
- Bugscope Teamwe can show you what it looks like, thoug
- Bugscope Teamh
- Bugscope Teamunless someone was willing to have part of their hand cut off, but i dont think we would have any volunteers
- Studentcoral: could you tell that the bug is sick
Bugscope TeamYes usually you can tell there is something wrong with it. Sometimes sick insects will turn a weird color, sometimes they will stop eating or have digestive problems. Sometimes they will act weird.
- Bugscope Teamscott is going to switch the scope to an internal camera, so you can see what the inside looks like
- Bugscope Teamthere it is
- Bugscope Teamnotice in the middle is the stage, that has the insects on it.
- 9:56 am
- Bugscope Teamabove the stage is the electron beam, i think, that shoots electons at the insects on the stage.
- Studentvery cool
- Bugscope Teamlet me know when you want me to switch back to the secondary electron camera (SE)
- Bugscope Teamokay, going back to SE mode now
- Bugscope Teamback to the white hair
- Studentevan: how old is it
- Bugscope Teamsometimes other insects will do tricky bad things like inject their eggs into a living caterpillar, and that might make the caterpillar sick
- Studentthank you!
- Bugscope Teamthis is from a guy who is in his 30's, I think. But the hair would not be 30 years old -- just a few months, likely
- Studenthave a great day
- Bugscope TeamAnd sometimes, other insects will lay eggs inside an insect...that makes them really sick and they other insects wll spin cocoons on the outside of an infected insect's body! Pretty gross!
- Bugscope TeamThank You !
- Bugscope Teamdoh
- Bugscope Teamhope you enjoyed bugscope!
- Bugscope Teamewe annie, that is gross!
- Bugscope TeamThank you all for the questions!
- Studentwe did, got to go now
- Bugscope Teamokay, bye bye
- Bugscope TeamSee you next time!
- Bugscope Teamif you have any other questions, just be sure to email us
- Bugscope Teambye bye
- Studentbye bye
- Bugscope Teamhave a great day
