Hair and Balloon Attraction

The balloon takes the loose electrons from your hair. Then the positive and negative charges attract.

Salt and Balloons Attract Salt is positive and

with the balloon rubbed against the wool, and it has more electrons than protons, so it attracts the salt.

Balloon and Wall Attraction

The balloons are charged negatively when rubbed against the wool. Since the wall is positive the balloon attracts to it.

Balloon and Can Races The cans are

attracted to the balloon, since opposites attract. Ellie and Kassi raced down the hallway with this experiment.

Lemon Battery Lab We used one lemon

to make a cell battery on the first day.

On day two, we used four lemons to create a series circuit to light a LED light.

Van de Graaff Designer Hats

Van de Graaff Generator The Van de Graaff

generator is a machine that transfers electrons from an internal belt to the dome, which produces static electricity.

Van de Graaff Discharge To discharge the

generator after an experiment, we used the discharge wand.

This prevents unexpected shocks from the Van de Graaff by transferring the extra electrons to the ground.

Vocabulary Repulsion - Same

charges in hair and the Van de Graaff jump apart from each other.

Attraction - Objects with opposite charges, like protons and electrons, come together.
