Here's a math, science, and social studies activity: help your kindergartener become a "coin archaeologist" by examining how different coins look and feel.

Alive or not? This yeast experiment you can conduct with your little scientist explores the answer to this timeless question.

Make scented sensory cloud dough. Add it to a sensory table, activity station, or put it in a baggie for extra at-the-park entertainment!

Help your kindergarten scientist predict and observe as she explores the science of smell...and have a great time doing it, too.

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

Get a better understanding of water content by dehydrating carrots.

This science fair project idea investigates whether air has mass and weight.

In this fun guessing game, your child uses his sense of smell and taste to figure out what is in the container. Here's how to play:

In this project, create and examine garden mulch to find out what critters live in the messy, muddy layers just above the soil.

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

This science project teaches young students about germs, bacteria, and the importance of washing their hands. Students will test what is the best way to wash.

This science experiment tests why guacamole goes brown and if leaving the pit in will stop guacamole from turning brown.
