In this science activity, you will find out how much of a compound is too much to dissolve.

In this science activity, you will make a little toy raft that is powered by surface tension, and use your vessel to investigate how surface tension works.

In this science activity, you will investigate the diversity (or biodiversity) of the animal life around your home and try to figure out which phylum most of the animals belong to.

In this science activity, you will stack several liquids, one by one, and create a colorful density column.

In this science activity, you will investigate the enzyme called catalase to find out how it helps to protect your body from cell damage.

Finding a cure for cancer is one of scientists' greatest challenges today. But in order for this to be possible, they have to study and understand the disease. This lab explores the software available on the Cancer Genome Anatomy Project...

Have you ever looked through a magnifying lens? Why do things look bigger when you look at them through the magnifying lens? Even though the object appears to get larger, it really stays the same size. Each lens has its own unique power...

In this lesson, students will explore how water is continually cycled among land, the oceans, and the atmosphere.

In this lesson plan, learners investigate what effect changing the direction of gravity will have on the growth of a plant's roots. Includes detailed instructions, videos, background articles, etc.

In this fun activity, students will get creative with craft materials. They will figure out how to protect an "animal" and its territory from getting too hot in the sun. What will they build to keep their animals cool?

In this activity, you will investigate some of the processes that make water move in and out of the atmosphere by making a miniature water cycle model inside a plastic bag.

Explore the world of drones as you build your own mini drone using popsicle sticks in this fun activity.

In this hands-on weather lesson, 3rd graders design, build and use their own rain gauge to measure how much water falls during a rain storm.

Middle schoolers will build a multi-stage balloon rocket that they can launch across the classroom while learning about real space flight and Newton's laws of motion.

Students will design, build, and race balloon-powered cars in this fun lesson that teaches about engineering design and kinetic and potential energy.

In this project, middle schoolers will build model earthquake-resistant buildings and measure their movement during a simulated earthquake using a mobile phone and a sensor app.

For this lesson, your young scholars will learn about kinetic and potential energy as they build their own roller coasters from simple classroom materials.

This lesson will introduce your students to the scientific method using a fun, hands-on activity.

Students build a device to protect an egg and prevent it from breaking when dropped.

Learn about the scientific method in this lesson that uses rockets made from nothing but paper, tape, and straws.

In this activity, you will get to build your own mini hovercraft. How will different amounts of air in the balloon affect how long the hovercraft hovers?

In this quick activity, you will make a simple motor using nothing but a battery, magnet, and a piece of wire.

In this activity, you will use an alien model to demonstrate how genes or physical traits are passed on from parents to their offspring.

In this activity, you will be able to observe the oxygen production in leaves by doing a floating leaf disk experiment. You can also find out how quickly plants produce oxygen, and what variables affect photosynthesis.
