This first grade science activity is great for winter! Your child will grow and observe her own amaryllis bulb, keeping a journal of her scientific findings.

This science fair project idea explores whether talking to a plant will help it grow.

Do you think you could walk around upside down -- with your feet in the air and your head on the ground?

Encourage your child to take ownership of a plant by creating a care plan and following it over the course of a couple of weeks.
