In this design challenge, your child will make a bottle rocket using typical household items.

In this challenge, students are tasked with creating an insulated cup that will keep beverages colder for longer than a regular cup.

In this microwave plant experiment, find out whether microwave radiation will affect radish seed germination. Will it help or hinder the plants' growth?

Find out whether a longer airplane will fly farther or a wider paper airplane.

Show your child how to construct a homemade thermometer. It's hands-on fun and a great way to learn about this important instrument!

This science fair project idea examines whether plants are still able to grow normally if they are turned upside-down.

Learners hypothesize about and experiment with soil erosion in this hands-on activity.

In science fair projects, middle school students discover why nitrogen fixing bacteria are important to plant growth.

For a fun family activity to introduce your child to genetics, have your child go on a search for dominant and recessive family genes!

Is there a relationship between caffeine and heart rate? Students will determine the effect of caffeine on heart rate in this fun science fair project.

This science fair project idea determines if the color of light affects the growth of plants.

This experiment explores the question of whether age and/or gender play a role in people's ability to remember dreams.

The goal of this evaporation experiment is to learn about how different external conditions affect drying time.

Learn all about balance and motion as your child designs a corn maze!

This science fair project explains the process of how the lungs expand and contract with the help of the diaphragm.

In this science experiment, do tensile strength test on fishing line, a strand of hair, a rubber band, and any other materials you're curious about!

This science fair project idea explores the different properties of matter.

Learn how to make a hygrometer to measure relative humidity in this project. Make a sling psychrometer hygrometer with gauze, thermometers, and a bottle.

The objective of this science fair project is to observe the differences in heat absorption for darker colors vs. lighter colors.

This science fair project idea determines what household items are good conductors of electricity.

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

Science fair project examining barometric pressure, and how it can be used to predict the weather. How does atmospheric pressures relate to weather conditions?

Discover that the absorbency of fabrics depend largely on the shape and structure of the individual fibers that make up the fabric.

In this cool physics experiment, use double plane mirrors at various angles to learn about light reflection. Then, see if you can solve a puzzling problem!

This science fair project idea explores which fruit molds the fastest.

This science fair project idea demonstrates that light travels in straight lines and experiments with reflecting light.

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.

In this open-ended activity, students will be given a small quantity of three types of materials and asked to design a prototype for “something that will improve the school.”

In this project students experiment with making music using only glasses of water.

In this cool project, create a lighted, scale model of the different layers of the Sun, including the core, radiation and convection zones, and photosphere.
