Methane Hydrates – What's the Big Deal?
Have you ever tried to light ice on fire? With methane hydrate, you can do exactly that. The ice forms with methane inside so it looks like ice, but is able to burn. The lesson uses group research and a hands-on activity to help scholars...

The Earth's Magnetic Field
Students explain how the earth's magnetic field works and looks. They create
their own free-floating compass using the everyday materials. After constructing their compass, they test it and determine north.
