Set up a fun guessing game for your curious kindergartener, one that will test her ability to use all five of her senses.

Does your child love learning about dinosaurs? Does he like digging around in search of hidden treasures? In this fun activity he'll do both!

With this hands-on activity, you'll show how fall colors are hidden in the leaf all year long!

In this activity, find out who the flowers' "partners in crime" are by being a flower spy!

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

Take a nature walk in your backyard or local park to find one object for every letter of the alphabet. Then put them together in this handy nature book.

Demonstrate how static electricity can cause an object to move. It also examines just how an object affected by static electricity will move.

Here's an investigative activity in which your child will discover real-world names and uses for sugar and find out how it is hidden in many different foods.

In this cool experiment, learn how to find specific gravity of minerals using liquids of different densities to see which substances and items sink and float.

In this physics project, you'll learn how to find the maximum height of a projectile using some math and trigonometry.

This experiment will explore the possibility of creating an infinite object by hand.

Water can go from solid to liquid to gas...but how does popcorn go from kernel to snack? Invite your first grade scientist to find out.

In this science fair project on the relationship between distance and time, kids explore the behavior of gravitational acceleration through direct observation.

This science fair project idea investigates how the shape of an object affects drag.

In this project, all you need is a protractor to learn how to use the altitude of Polaris to find latitude on Earth. Polaris is also known as the North Star.

Demonstrate the relationship between mass, volume and density. Measure displaced water, and weigh object to calculate mass and density.

This science fair project idea shows how a vibrating object transfers energy to whatever it touches.

This project examines Newton's First and Second Laws of Motion with a bicycle and water balloons.

Science fair project that uses iodine vapors to develop latent fingerprints on a non-porous object.

This science fair project idea explores if objects dropped from a high distance will equal a greater impact force than the object dropped from a low distance.

This science fair project idea determines if the size of the parachute will change the rate at which an object falls.

Demonstrate and explain holographic technology. Determine if a holographic image of a magnifier still magnifies the object beneath it. Explain the effect.

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

In this simple circular motion experiment, you'll observe tangential velocity and learn about how acceleration and centripetal force affect an object.

This science fair project idea investigates how optical distances change the apparent size of an object as seen through a magnifying lens.

Find out whether matching resonant frequencies can cause objects to shatter.

Make "fossils" with your child to hide in the sandbox or at the park or the beach, to help your child explore his archaeological side.

Determine how different measurements of the same object might yield different values. Provide as many reasons that you can think of.

This science fair project idea discovers whether there are some objects that do not fall at a constant rate.

Would your child like to learn about a hidden world? All she needs to do is open her box of markers!
