• Bugscope Team just setting up now

• Teacher hi

• Teacher i am home schooled. My name is tyler]
• Teacher I am 8

• 8:31am
• Bugscope Team hi tyler!
• Teacher hi

• Teacher what are we going to do?
• Bugscope Team In a few minutes you will be able to control the microscope and move to different insects

• Teacher ok thanks.

• 8:36am

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

• Bugscope Team good job!

• Teacher this is cool

• Bugscope Team some ants will sting you and some ants will bite you and then spray formic acid into your wound
• Bugscope Team you can see little barbs to the upper left
• Bugscope Team those help cut into your skin
• 8:41am
• Teacher why is it black and white
• Bugscope Team like a steak knife

• Bugscope Team we are using electrons, not light, to image.

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

• Bugscope Team they are particles that float around atoms.

• Teacher what thing should i do?
• Bugscope Team electrons have a negative charge. There are also protons and neutrons.
• Bugscope Team Click on the arrow to the left of the screen and click on an image to move somewhere else

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

• Bugscope Team each can see part of an image

• Bugscope Team crane flies kind of look like giant mosquitos

• 8:46am
• Teacher how big do they get
• Bugscope Team but they won't bite you. They suck up nectar from plants
• Bugscope Team some can get around a couple inches big

• Teacher eew

• Teacher can you look at human body parts
• Bugscope Team There are a couple little balls here- those are brochosomes

• Teacher the bronchosomes are on the insect's lenses??
• Bugscope Team we 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 Team This is part of the lens

• 8:51am

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

• Bugscope Team back 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
• Teacher what is the hairy stuff
• Teacher do they have teeth
• Bugscope Team They are the wasp's hairs
• Bugscope Team they don't have teeth, but they have mandibles/jaws that open out like a gate

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

• Bugscope Team you can see lots of hairs here
• Teacher is that a mouth?
• Bugscope Team the hairs help them to feel what is going on around them. They don't have sensitive skin like we do
• Bugscope Team no that is a division in one of its body segments

• Bugscope Team there is the mouth at the top

• Bugscope Team think of it as looking up
• 8:57am

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

• Teacher thank you for the help on bugs bye

• Bugscope Team i hope you had fun
• Teacher i did bye
