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...

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

This simulation begins with an exploration of water pressure and atmospheric pressure. In the flow portion, scholars reshape a pipe and see fluid dynamics at work. The water tower portion encourages pupils to determine how water...

Eighth graders identify and explain what Bernoulli's Principle is and draw diagrams to incorporate Pascal. They also perform simple calculations of density, buoyancy, and fluid pressure. Finally, 8th graders describe fluid pressure in...

Students develop critical thinking and awareness about the complexity of natural resource use, wealth distribution, population densities, poverty, and the environment. They think about people living in different parts of the world and...

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