Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...

Second graders investigate the properties of solids and discover how to classify them. Using rulers, they measure various solids on display. In groups, they play an identification game where one students names a location, such as the...

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...

Students describe the motion of solids, liquids and gases. In this chemistry lesson, students describe how temperature affect motion of the particles. They determine the physical properties of each phase.

Students pretend they are water droplets traveling through the water cycle. Using their text, they discover the steps in the cycle and the different paths water can take. They write a report about their journey through the water cycle...

Young scholars identify the elements that make up the earth's weather. Begin by having students pretend they are hiking along a mountain ridge. It's been sunny and warm all day, but you see a dark line of clouds moving from the west.

Students examine the phases of the water cycle and water's different forms it can have. They work in groups to create pantomimes to illustrate the water cycle to their classmates.
