In this science fair project, kids measure how weather conditions affect how fast a puddle evaporates.

You don't need to head to the Arctic to experiment with life in an igloo. Learners can build their own ice igloo at home from water and empty milk containers.

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

Here's a fun math and science activity: help your child explore four different kinds of measurement, using their hand and a few simple household tools.

Explore the scientific concept of capacity by seeing how many pennies you boat can hold before it sinks!

This will encourage your child to utilize their observation skills, develop aesthetic awareness, build artistic drawing abilities and learn about the seasons.

How do we know that air exists when we can't see it, taste it, or touch it? Here's a classic experiment that will teach your kid some basics of aerodynamics!

Is our water polluted? Help your young scientist understand the importance of taking care of the environment with this simple experiment.

The goal of this fun science fair project idea is to microwave candy and investigate: do some colors of M&Ms melt faster than others?

Get your child math and science savvy with this fun outdoor classification game. Using chalk, your child will classify what she sees in the natural world.

Here's a classic celery science experiment that uses celery and food coloring to demonstrate how plants absorb water.

Here's a science activity to help your child investigate how seeds are designed to travel.

Put an oatmeal box, a flashlight, and some construction paper together and you have the makings of an incredibly cool bedroom planetarium!

The fish most kids see is usually filleted, and it's hard to see how it came from a lake or sea. This cool gyotaku activity blends life science with art!

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

This experiment works due to a simple principle: plants need light. Build a shoebox maze and watch the plant work though the obstacle course, searching for sun.

Teach your child about recycling and gardening as she re-uses an empty plastic milk gallon jug to craft a swan-shaped plant container!

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

Take this "paper plate snack test" with your child for a hands-on lesson in making healthier choices to teach your child about what's in his food.

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

Your kid will be captivated as she watches liquids change color before her very eyes during this fun science project that introduces some chemistry basics.

In this experiment, students will create their own version of coquina, a sedimentary rock thatâs formed by seashells and sand, cemented by seawater minerals.

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

This is a fun way to introduce kids to the concept of volume, and give them a quick hands-on activity to boot.

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.

In this science and engineering activity, children will explore types of tunnels and their purposes and then design and build a tunnel of their own.

What is surface tension? Kids will discover how water-skating insects use surface tension to keep from sinking by making a model water walker.

Give your local birds a treat — and your young birdwatcher some fun — with this simple DIY bird feeder.
