This lab is one of the most popular for obvious reasons! In it, students will investigate static charges on balloons, an electroscope, and the Van de Graaff generator. This is a straight-forward lab, but some teacher set-up time is needed. Teachers will need to provide a Van de Graaff generator, an electroscope, and enough balloons and tissue paper for each student. Make sure that none of the students are allergic to latex and use cheap tissue paper, the kind without any lotion if possible. Also, clean the Van de Graaff dome with alcohol before use to get the best effects possible.
The Mythbusters examine whether a tongue piercing will attract lightning during a storm, see if a handmade medieval cannon could explode with deadly consequences, and test if there is any way to beat the breathalyzer test. Topics of interest include electrical conductivity, electrical fields, electrical engineering, experimental controls, manipulating experimental design variables, metal contraction, Newton’s Third Law of Motion, a discussion of the relationship between mass, force, and acceleration, Newton’s Second Law of Motion, alcohol metabolism, and public safety.
