This hands-on activity explores the concept of static electricity. Students enact a "human diagram" of the Bohr model of an atom. Then, in pairs, they charge a comb (on hair) and use it to attract an O-shaped piece of cereal and then watch the cereal jump away when it touches the comb. They do the same with Styrofoam pellets, observing them pulling towards a charged comb, then leaping back to the table. Students gain an understanding of what's going on at the atomic level.

    Engaging Activity
    I made a lab out of it... having students record number of times the balloon was rubbed to the amount of time it took for the item to loose it's "stickiness". The students enjoyed comparing how much longer their item held on to the balloon. I will be following up with a graph and discussions on why people had different times for the same number of rubs... introducing the human error factor :-)
