Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

In this classic reaction, learners baking soda and vinegar in a soda bottle to produce carbon dioxide (CO2) gas. This gas inflates a balloon.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

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.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

In this activity, learners make a helium balloon "flink"--neither float away nor sink to the ground. Use this activity to introduce physics concepts related to gravity, density, and weight.

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.

En esta actividad, los aprendices experimentarán con las tres fases del agua. Intentarán controlar la rapidez de los cambios de estado al manipular la temperatura y la presión del agua, hielo, y gas.
