The possibilities are endless with this fun Halloween-themed STEM activity! With simple supplies, your child will experiment, adapt, and use their creativity while they build structures using different specifications.

Teach your child how to make an all-natural, yellow-brown dye, using just walnut shells and water. This deep dye can be used on textiles, art, and wood.

Here is a nifty science experiment using Epsom salts to make "frost" appear on a piece of glass.

Your child will create her own falling snowflakes using white paper and glue them over a tree, so it appears as if they are falling from the sky.

Here's a fun at-home activity that will help your child strengthen math skills using high and low temperature data, and become a master temperature tracker!

Sink or swim? Calculate the density of various fruits and vegetables using water and a kitchen scale.

This cool science fair project teaches kids about temperature, density and buoyancy using balloons that float with normal air. No helium required!

The objective of this science fair project is to examine the basic principles of air pressure using simple materials like a balloon, straw and string.

Demonstrate the properties of pressure and surface tension to explain how water can stay inside an upside down glass using cardboard.

Using simple materials found around your home, you can reinforce the static electricity concept by helping your child build a simple device with zapping power!

Demonstrate how you can make your own compass using a magnetized needle. It also allows you to compare magnetic north and geographic north.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

Gymnosperms are coniferous trees that reproduces using pine cones to spread seeds. Check out this simple pine cone experiment to learn about the process!

Make your own helicopter using a paper clip and a sheet of paper. Hold the spinner up in the air, let it go, and watch it spin gracefully to the ground.

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

Explore the craters, maria, and highlands on the surface of the Moon! In this fun science project you'll create a 3-D model of the moon using paper mache.

Every time a sound is produced it emits a sound wave. This experiment demonstrates how sound travels, using nothing more than a spoon and a string!

Experiment about connection of senses of taste and smell. Using blindfold and noseplugs, administer blind taste test. Analyze results and organize data.

In this free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.

This project determines the age of a tree using a growth factor chart instead of cutting the tree down to count the rings in its base.
