Seventh graders observe and test for the presence of carbon dioxide gas. They compare concentrations of carbon dioxide gas and conclude high concentrations of carbon dioxide gas are unhealthy for human beings.

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Second graders work with gases to determine what the effects of temperature are on volume and air pressure by working with balloons. Also, they experiment with vinegar and baking soda. They predict the outcomes of these experiments, and...

Ninth graders identify the characteristics of fish.
