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...

Take your class up, up, and away with an engaging weather balloon simulation! Individuals get hands-on experience in creating and launching their own airborne labs to study how temperature and pressure affect substances at 100,000...

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...

After a basic introduction to the rock cycle and the three main types of rocks, young geologists can deepen their understanding of how rocks change through a fun learning game. Based on the characteristics and events shared by a reader,...

Students define trash, garbage, or solid waste, discuss ways of disposing of trash, list examples of biodegradable materials, and have trash relay race in order to sort trash into appropriate containers labeled biodegradable, reusable,...

Young scholars simulate the search for water in Mars using simple apparatus. In this space science lesson, students explain how soil temperature affects the cooling of probes. They graph the data collected from the simulation.
