In this science fair project, young children will become aware of and have the opportunity to experience the four basic tastes: sweet, sour, salty, and bitter.

In this activity, your child will be challenged to make a tower using paper cups.

This two-ingredient dough, sometimes called "moon sand," is a quick and cheap way to let kids explore their senses, build fine motor skills, and play.

In this design thinking activity, your child will choose an animal to research, learn about the animal’s habitat, and then replicate the animal's habitat using household items.

This science fair project idea investigates which objects float and sink in honey, water, and oil.

The goal of this fun science fair project idea is to microwave candy and investigate: do some colors of M&Ms melt faster than others?
