This experiment works due to a simple principle: plants need light. Build a shoebox maze and watch the plant work though the obstacle course, searching for sun.

Introduce your child to science with something they see everyday--their shadow!

How many steps long is the hallway? Kids put their graph-making skills to work as they make a step map of their own house.

Encourage your kindergartener to investigate and chronicle the weather she observes during the coldest months of the year.

Gather the neighborhood children together and practice graphing with this backyard tournament!
