Question

You observe that the hair on your head stands up when a charged balloon is brought near without touching your head. Based on this observation, you write down the following question and steps to an experiment.
Can two charged objects be attracted to each other without touching?

Step #1: Bring the charged balloon 10 cm from your head.
Step #2: Charge the balloon by rubbing it against a cloth.
Step #3: Record your observation.
Step #4: Bring the charged balloon 5 cm from your head.
Step #5: Record your observation.

What revision could you make to improve the experiment?

Remove the fifth step, you do not need to make multiple observations in an experiment.
Reverse the first two steps so that you charge the balloon before you bring it close to your head.
Reverse the second and third steps so you record your observation before you charge the balloon.
Swap steps two and four, you do not need to charge the balloon until the end of the experiment.
