Given a variety of rocks, junior geologists calculate densities and correlate them to Earth's layers. As a simulation of continental crust, they experiment with how materials of differing density float in water. Finally, they...

Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

Students explore physical science by participating in a class experiment. In this chemistry lesson, students discuss what they predict will happen when cooking oil and water are blended together. Students utilize a plastic bottle,...

Students examine how a hot air balloon works. For this hot air balloon lesson, students do an experiment to test the effects of heat on density. Students make their own hot air balloon and act out how nitrogen moves when turned to a liquid.

Young scholars experiment by creating an oil spill and trying a number of clean up methods. They determine which methods are the least costly and most effective. They role play as an environmental engineer and as an oil company owner who...

Students observe earth science by examining results from an experiment. For this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...

Students investigate how temperature and salinity causes ocean layering. In this ecology lesson, students observe and sketch their experimental result. They report their findings in class.

High schoolers conduct a variety of experiments to explore gel electrophoresis. In this biology instructional activity, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Students determine how to use a quarter meter quadrant to find population density, relative density, frequency and how to calculate a diversity index while participating in a virtual field trip. They study how to establish a Correlation...

Students use a demonstration in order to learn abou the movement of weather fronts.
