It's a rare kid who doesn't like a sandbox. Next time you're out digging, build in some earth science, too.

The next time you've got a restless second grade earth scientist on your hands, use this experiment to demonstrate crystals and make a tasty treat, too!

This science fair project idea teaches how the gases and pollution in the air affect the earth's atmosphere temperature.

Learn about the role of Earth's rotation on the Coriolis Effect and hurricanes in this science project. Model the Coriolis Effect on a hurricane's direction.

Check out this cool science project idea to learn about rocks and explore the cycles of formation, breakdown, and reformation of rocks in the Earth's crust.

What is the hydrologic cycle and how does it work? Check out this fun and easy science project where you will model and learn about Earth's water cycle!

This project uses science and art to help students learn and teach others about Earth's endangered and extinct species.

Leave your computer on 24/7. Will this lead to to more frequent crashes, freezes, and a slower processing speed? Find out in this science fair project idea.

How do the phases of the Moon and gravity cause spring tides and neap tides? Does the Sun play a role in the tides? Figure it out in this fun science project!

This experiment evaluates if people have an accurate perception of how much personal time they spend interacting with technology.

This experiment challenges students to forecast the weather based on the surrounding areas' weather.

Research and understand basic computer science. Build a simple computer, following instructions found online. Design a new or improved feature.

This experiment will explore if and where fractals can be found in the natural world.

Start thinking about how the internet works by assembling an Ethernet cable of your own!

This simple experiment serves as an introduction to the greenhouse effect.

The objective of this project is to evaluate whether a top will spin at different rates during different phases of the moon.

Examine the influence of the phase of the moon on moisture capillarity in garden soil. Measure and record the depth at which water is first detected.

This science fair project idea investigates how magnetism can defy the force of gravity.

In this fun science fair project, make two different scale models of our solar system using Astronomical Units and planets' relative size!

Learn how to tell time by the sun with this cool science fair project idea that tracks how the accuracy of a sundial changes over time.

This science fair project idea researches the different layers of the atmosphere and creates a visual representation of the atmospheric layers.

In this free science fair project, build a star clock and learn how to tell time on a clear night by observing the big dipper!

The apparent movement of the sun has been used to keep time since the bronze age. In this science fair project, kids plot solar time against mean solar time.

We all know that the Moon has different phases, but it can be hard to figure out why. Try this activity to see how the Moon's phases really work.

This science fair project idea recreates the movement of planetary bodies in order to learn why they sometimes appear to move backwards.

What is a barycenter? Kids learn how gravity and mass influence the orbit of binary systems like planets and moons or stars and planets in this cool experiment.

Choose a timeline to live without technology. Keep a journal of all the issues encountered. What are the benefits and cons of modern technology?

How does water pressure change with depth? Kids learn how pressure works underwater with this cool and easy demo.

Science fair project that determines how UV radiation emitted by the sun varies depending on the time of day, using a handheld UV detector

Compare air temperature with the infrared temperature from a reflecting surface at different times of the day, in shade and in sunlight.
