Learners use a simple process to extract DNA from strawberries.

Learners observe a sealed container holding a clear colorless liquid. They shake the container and the fluid turns blue. When allowed to sit for a few moments, the fluid turns colorless again.

In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

Did you know that some breakfast cereals are fortified with ferric phosphate, while others contain tiny pieces of reduced iron?

In this activity, learners will explore pi and the mathematical relationships between a circle's diameter, circumference, and radius.

Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

Learners build a lever and use it to lift a load. With the load on one end of the ruler, learners add coins to the effort cup at the other end until the load is lifted.

In this activity, the learner will explore hand eye coordination while using a variation of the ball and cup game.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this activity, learners will use string and salt to lift an ice cube out of a glass of water. Salt depresses the freezing point of water, allowing it to melt around the string and refreeze.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

This activity was designed for blind learners, but all types of learners can explore the process of extrusion used to produce pipes and wires in industry.

In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.
