In celebration of Earth Day, help your fifth grader write a poem from the Earth to its inhabitants.

Prove that the Earth is not flat. The objective of this science fair project is to measure the angle of the sun and calculate the circumference of the Earth.

Science fair project which measures the shadow cast by a meter stick at various times in order to predict the circumference of the earth.

Grow borax crystals and get your child excited about Earth science with this crafty science experiment.

Have your kid determine if a goldfish can be conditioned to expect food the same way Pavlov's dogs did with this fascinating science fair project.

This science fair project idea examines the distance a person travels on an average day and to relate that to an understanding of the size of the Earth.

Get your fifth grader involved in some earth science by helping her plan and create her very own rock collection.

What cause the phases of the moon? Make a model to see how the positions of the Sun, Moon, and Earth cause the crescent, gibbous, quarter, full, and new moon.

Science fair project which determines whether it is numerically possible to be connected to every person on the earth within six degrees of separation.

In this game, players will learn interesting facts about animal adaption and practice them using a fun matching card game!

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.

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

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 simple experiment serves as an introduction to the greenhouse effect.

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

This science research project challenges students to think of more effective lobster farming methods.

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

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

All you need are pencils, paper and some scissors to get started on this easy and fun game to review astronomy information, or other types of study concepts.

In this activity your child will make a coiling snake out of simple household materials, and also find out why they coil.

How do organic materials become soil? This science experiment measures what materials biodegrade.

Science fair project which compares the rate of temperature change and the maximum temperature as a result of the angle of light radiation.

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 activity, children will let their imagination run wild as they design and build a new planet in the solar system.

Science fair project that determines whether mass and weight are the same or different.

Demonstrate how static electricity can cause an object to move. It also examines just how an object affected by static electricity will move.

Are you looking for an out-of-this world activity that's both fun and educational? This solar system garland is a great way to introduce your child to astronomy.

The objective of this science fair project is to experiment with balancing everyday objects and observing the the effects of gravity on materials.

This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.
