Do you know why it's called a watt? an ohm? a volt? Your students will know after this thorough history. From amber and fur (600 B.C.) to jumping frogs (1786) to electrical resistance (1827), this unit is a fantastic introduction to the history of electricity.
You know what you weigh on Earth (even if it doesn't make you happy!!)--but what would you weigh on Mars? on Pluto? Students combine science and math in this fun gravity lab.
This lesson (including lesson plan and worksheet) explains food chains, and then offers students a variety of activities to illustrate and expand their knowledge.
Students read a story about a typical day in one man's life, then isolate the over 20 uses of electricity, concluding by rewriting the story without electricity.
