Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

Learners mix vinegar and baking soda together in a bottle to create a chemical reaction. The reaction produces a gas, carbon dioxide, which inflates a balloon attached to the mouth of the bottle.

Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

Learners make a circuit board that has questions and answers. When the correct answer is chosen for a question, a circuit is completed and a light illuminates.

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.

Learners build a wind turbine and test it to see how much energy is created.

Learners attach an egg to a rubber-band bungee cord and drop the egg.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

Learners follow the template to build and fly a paper helicopter.

Learners build pan pipes out of drinking straws by cutting them to different lengths. Then, learners make music by blowing across the straws and playing some well-known songs.

Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.

Learners act as engineers and design mini submarines that move in the water like real submarines.

Learners analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

In this activity, learners investigate static electricity using everyday objects at four different stations.

In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.

Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.
