I made this powerpoint to teach my grade six science class about atoms and static electricity. After the lesson, students made their own atom diagrams. I highly recommend starting the lesson off with the "Swing cereal magic trick" on static electricity! I have a lesson plan that comes with the powerpoint called Atom and Static Electricity lesson plan. It is also free and the "magic trick" is included in the lesson plan.
If you enjoy teaching this lesson as much as I did, I have a series of powerpoints and lesson plans as part of the electricity unit that will soon be available for purchase. Happy teaching!
