Find out which kind of bubble wrap fares best when put in impact.

This science fair project idea provides evidence that air is everywhere and takes up space.

What chromosome combinations determine a fetus gender? Use probability to think about whether a sperm and ovum will create a male or female in this project.

Young scientists will investigate people's preferences for saltiness, and make some inferences about genetics and diet.

This fun experiment provides a concrete and visually striking illustration of photosynthesis.

Discover whether a metal will expand under hot water.

This science fair project will help students learn about non-vascular plants, such as mosses.

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

This science fair project explores how osmotic pressure forces water through the root up into the plant.

The purpose of this science fair project is to study the properties of sugar and examine individual preferences for sugar and other sweeteners.

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

Soil and energy don't go together, right? That would be as bizarre as a pairing of peanut butter and marshmallows! Well, actually...

Step into the fantastic world of colors with a project that explores what shade you -- and your friends -- like best.

This science fair project idea examines whether adding gelatin causes a solid to have a higher melting point and/or melt slower.

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot navigate around several obstacles.

In this science fair project, students examine under what conditions individual plants release seeds and how far the seeds are released.

Find out whether putting something on top of a plant will inhibit its growth.

This science fair project idea explores how enzyme inhibitors, active sites, non-competitive enzyme inhibitors, and substrates work.

This project investigates the affect of storage temperature on microwave popcorn.

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.

This science fair project idea investigates how the height at which a pendulum is released affects the length of time it continues.

In this science fair projects, students will grow out the bacteria that collect on air conditioner filters.

Learn about the microclimate of your backyard by tracking rainfall, temperature, and observed weather with hand drawn charts and graphs.

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot move in a pattern related to the sound and rhythm of music.

In this activity, children will work on their mathematics and engineering skills as they attempt to recreate the Eiffel Tower out of building blocks!

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.

Have you ever noticed the way a dropped stone makes a fun pattern in a pond or lake? What's the science behind these splashy occurrences?

In this activity, your learner will be challenged to create their own tic-tac-toe grid out of building blocks.

In this science fair experiment, children demonstrate the relationship between the amount of stuff and the amount of pressure in a closed system.
