In this activity, your student will be invited to build a chair out of building blocks that is designed to meet the specific size and shape of a small doll or toy figure.

In this project combining nature, art, math, and science, children make rubbings of leaves then observe shapes and structures and sort the leaf images.

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.

Learn about the layers of the Earth and make a model! Create a earth layer book, cake, or clay diagram.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

This science fair project idea investigates if webbed feet help a duck (and others) swim.

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.
