Teach your first grade scientist the difference between liquids and solids using maple syrup.

For your budding first grade scientist, all you need is some simple, natural materials to create an amazing ant farm. Here's how to get started.

Check out this fun science fair project idea for 1st grade: a solar eclipse model that demonstrates total, partial, and annular solar eclipses.

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

In this project children practice the scientific method while playing with puffy paint.

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

In this science fair project, kids observe the expansion of liquids when frozen and determine if some liquids expand more than others in the freezing process.

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

The objective of this science project is to determine the length of time for different seeds to germinate.

Here's an easy experiment that lets your first grader practice the scientific method, while watching a caterpillar eat.

In this exciting and empowering challenge, your child will construct a bridge using marshmallows and toothpicks!
