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.

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...

Students experiment with acids and bases using technology-based "probe-ware", computers, and household products in this exciting biology/chemistry lesson. The lesson was written for an advanced 6th grade class.

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...

Students investigate landforms by holding a class experiment. In this topography lesson, students define the word "karst" and discover why sinkholes are created on the surface of the Earth by completing worksheets. Students create a...

Middle schoolers use the internet to research air bags in cars and trucks. In groups, they discover air bags history and the safety issues surrounding them. They create their own design of a new air bag and test it using a raw egg in...

Students identify the signs that a chemical reaction took place. In this chemistry lesson, students role play the movement of different molecules of matter. They classify matter according to their properties.
