• 8:36 am

• Bugscope Teamif you want, you can control the microscope now
• Bugscope Teamby clicking on the left blue button you can choose from different presets I made

• Bugscope Teamgood job!

• Teacherthis is cool

• Bugscope Teamsome ants will sting you and some ants will bite you and then spray formic acid into your wound
• Bugscope Teamyou can see little barbs to the upper left
• Bugscope Teamthose help cut into your skin
• 8:41 am
• Teacherwhy is it black and white
• Bugscope Teamlike a steak knife

• Bugscope Teamwe are using electrons, not light, to image.

• Bugscope TeamElectrons are much smaller than the wavelength of light, so we can magnify much higher. Right now we are about 20,000x magnified
• Teacherwhat are electrons

• Bugscope Teamthey are particles that float around atoms.

• Teacherwhat thing should i do?
• Bugscope Teamelectrons have a negative charge. There are also protons and neutrons.
• Bugscope TeamClick on the arrow to the left of the screen and click on an image to move somewhere else

• Bugscope Teamadult insects have compound eyes, which are made up of lenses called ommatidia

• Bugscope Teameach can see part of an image

• Bugscope Teamcrane flies kind of look like giant mosquitos

• 8:46 am
• Teacherhow big do they get
• Bugscope Teambut they won't bite you. They suck up nectar from plants
• Bugscope Teamsome can get around a couple inches big

• Teachereew

• Teachercan you look at human body parts
• Bugscope TeamThere are a couple little balls here- those are brochosomes

• Teacherthe bronchosomes are on the insect's lenses??
• Bugscope Teamwe could, but they wouldn't look very good. The body part would shrivel when it dries up. (Everything has to go into a chamber that pumps to a vacuum)
• Bugscope TeamThis is part of the lens

• 8:51 am

• Bugscope Teamthe little balls that were on there earlier are nanoparticles that are made only by leafhoppers, but got onto the fly somehow

• Bugscope Teamback to the bodyparts- insects are nice to use for this because when they dry, they don't often shrivel up because of their hard exoskeletons
• Teacherwhat is the hairy stuff
• Teacherdo they have teeth
• Bugscope TeamThey are the wasp's hairs
• Bugscope Teamthey don't have teeth, but they have mandibles/jaws that open out like a gate

• Bugscope Teamthis beetle is a type of a borer beetle, like the emerald ash borer. They eat trees

• Bugscope Teamyou can see lots of hairs here
• Teacheris that a mouth?
• Bugscope Teamthe hairs help them to feel what is going on around them. They don't have sensitive skin like we do
• Bugscope Teamno that is a division in one of its body segments

• Bugscope Teamthere is the mouth at the top

• Bugscope Teamthink of it as looking up
• 8:57 am

• Bugscope Teamthese are special hairs that help the insect to taste and smell food
