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.

This experiment examines whether storing your orange juice at different temperatures affects its acidity.

In this experiment you will replicate the mummification process by making a hot dog mummy.

Glass is see-through, but usually you can still see that it is there. In this experiment, we use baby oil to make glass go completely invisible.

Find out whether cast iron or regular teflon pans heat up faster and also retain their heat longer.

Study the life cycle of the common blowfly as it relates to forensic investigation. Record the first time you see flies, maggots, and eggs.

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

Demonstrate how to tell the age of an egg without having to crack it open.

Create a DIY Electromagnet! Using a 9v battery to create an electrical field around a nail, students explore electromagnetism in this cool science project idea.

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

In this science experiment, observe convection currents forming and learn about how heat energy moves in liquids from hot to cooler areas through convection.

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.

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!

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

This study evaluates if electronic devices commonly found in most households emit radiation, and if they do, how much?

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

Find out which type of sponge holds the most water.

This experiment has students record rat behavior to learn about the benefits of rats and research rat myths throughout history.

This project examines whether people's taste perception is influenced by what they see.

This science project teaches students about organic farming and the benefits and disadvantages of commercial plant food.

Explore how sound waves are reflected and absorbed by producing echoes. Analyze which locations produce echoes.

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!

Some fossils have been been preserved for billions of years! Help your kid understand how fossils are created and preserved with this crafty project.

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