Photos: Kickoff of STEAM program at John Kennedy
Fourth-graders at John Kennedy School on Friday were introduced to the STEAM (Science, Technology, Engineering, Art+Design, and Math) curriculum with science demonstrations, and some hands-on experiences, led by Batavia High School science teachers Nathan Korzelius (top photo) and Burton Howell.
In these photos, Korzelius talks about the properties of lycopodium clavatum, a powder derived from a species of moss. As Korzelius demonstrated, the powder floats on water and if a person sticks his or her hand in, the powder keeps the hand dry. When the powder is concentrated near a flame, it will explode in a flash of flame and lights (side fact: lycoduium was used by early photographers as a flash powder).
