Weather_and_Static_Electricity
First grade Earth Science lesson
Liaison: Andrea Kurtz
Date: 11/15/99
Group Members: Manoj and Kate
School: Tobin
Teacher: Laura Groff
Materials:
hot pot
ice
pie plate
rabbit fur
glass and teflon rods
balloons
pith balls
Procedure:
We described three kinds of weather phenomenon: rain, lightning, and the fact that thunder travels slower than lightning. For the rain, we boiled water and condensed the steam on the bottom of a pie plate that we had filled with ice. We also described the water cycle. We talked about how lightning is static electricity on a much larger scale, and did some static electricity experiments. we charged balloons and stuck them to the wall, we charged the teflon rod and brought near a coke can and made it move, we charged pith balls both similarly and oppositely and watched them repel and attract. we also gave each student two strips of scotch tape and had them rip them off the same surface, charging them similarly, and had them rip the strips off each other, charging them oppositely. we showed that sound traveled slower than sound by standing at the end of a hallway and clapping, showing them that the sound didn't quite match the instant my hands struck one another.
Evaluation:
we ask them what they think would happen given two similarly charged objects and two oppositely charged objects. basically we just kept asking them questions.
