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

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

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

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

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.

This science fair project idea explores if the length of the string that an object is suspended on has an effect on how fast or slow it swings.

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.

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!

Here is a kindergarten activity that blends art and science by using magnets, paint, and objects found around the house to create a picture.

Here's a household scavenger hunt that shows kids the natural sources behind everyday objects...and builds reading skills, too!

In this simple and social activity, children use size comparison skills to find objects in nature that are bigger, smaller, longer, and shorter.

Science fair project that develops latent fingerprints on a non-porous objects by converting superglue from a solid state to a gaseous state.

This science fair project idea demonstrates how air resistance contributes to denser objects falling faster than less dense objects.

With some cookie dough and ordinary household objects, let your kindergartener explore how fossil imprints are made.

Play this flashlight game with your child to teach him about objects that are transparent, translucent, and opaque.

In this activity, young learners will make a balance using a plastic hanger and weigh a variety of small objects using candy corn.

This plaster fossil activity is a fun supplement to preschool science. Use plaster to make imprints of your child's handprints, footprints and other objects!

In this awesome science fair project idea, kids will be attempting to pick up different objects using snail slime.

The goal of this science fair experiment is to demonstrate the effects of air pressure on objects and analyze applications of air pressure principles.

In this activity, students will think about the form and function of household objects as they compare and contrast kitchen serving spoons of various sizes and designs.

Here's a first grade ladybug game that explores how air can move solid objects, and adds some measurement practice, too. Play, learn, and enjoy!
