What are Hilary Erickson's top science fair project ideas for kids?

Based on the content I have, Hilary Erickson suggests choosing a science fair project that aligns with your child's interests. Here are a few ideas she mentioned:

• If your child loves Legos, see if the size of the brick matters when building a tall tower.
• If they enjoy video games, examine if their positioning changes their performance in a game.
• If they're into Hot Wheels, test which car goes the farthest off a slide.
• If they're fascinated by Barbies, investigate if they disintegrate in water.

She also suggests turning common household questions into projects. For example, you could test which paper towel is the best or if stain remover really works. The key is to ensure your child has a good amount of input into the project to maintain their interest level.

What age group is your child in? I might be able to provide more specific suggestions.
