Air Pressure
Fourth graders observe a demonstration experiment showing air pressure. They explain air pressure by completing the worksheet.
Curated OER
Landfills and the Potential for Groundwater Contamination
Young scholars examine how a sanitary landfill is constructed, how it functions, and how waste and leachate affects the areas around the landfill. After a discussion about landfills and leachates, students construct a Sanitary Landfill...
