Here is a fun electricity science experiment to try with them.
Experiment:
Do different hair colors have different effects on static electricity?
Materials:
- 12 lightly colored balloons, all the same size
- Notebook
- Pencil
- Permanent marker
- Timer
- 1 red-haired friend
- 1 brunette (brown-haired) friend
- 1 black-haired friend
- 1 blonde friend
- Clear wall space
- Have your child consider what they know about what happens when they rub a balloon on their head. Using these notes, have them take a guesses to what might happen to the balloons as they rub them on brown hair, blonde hair, black hair and red hair. Make one guess for each color of hair. Does hair color affect static electricity? Have them write down there guesses, or hypotheses in their notebook.
- Blow up each of the balloons so they're all roughly the same size. You can use your breath or an air pump to blow them up, if this makes it easier - careful not to get too dizzy! Close off each balloon with a secure knot.
- Using the permanent marker, write "Brown" on three balloons, "Red" on three more, "Blonde" on the next three, and "Black" on the last three. You're going to test each hair color three times to get the most accurate result possible.
- Using the balloon marked "Red" on your red-headed friend, rub the balloon on his or her hair.
- Once you've made the hair stand, stick the balloon to the wall and use the timer to time how long it stays on the wall. When the balloon begins to fall, stop the timer.
- In your notebook, create a table like the one outlined below. You should have 13 rows and 4 columns. The far left column should have the hair colors listed (Red, Brown, Blonde, Black). Then, each column should list the time trials (Time 1, Time 2, and Time 3).
- In the column labeled "Red Hair," note how long it took for the first balloon to fall from the wall on your chart under Time 1 for the first time you did it.
- Repeat steps 5 and 6 two more times with the red-haired volunteer and the balloons marked "Red". Then, list the second time under Time 2 and the third under Time 3.
- Write down how long each balloon stayed stuck to the wall after each trial.
- Repeat steps 5 through 10 with the brown, blonde, and black-haired volunteers. Don't forget to write your times as soon as you finish each step.
