Which travels faster, light or sound? Scholars work in groups to simulate the ability for waves to travel through solids, liquids, gases, and through a vacuum. Then, they learn about the properties of a mystery wave and must determine...

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...

High schoolers explain how the elements are arranged in the periodic table. In this chemistry lesson, students determine the subatomic particles for certain elements. They research the physical and chemical properties of an element they...

What can bulldozers and screen doors have in common? Use this lesson on fluid power to find out. It begins with some simple teacher demonstrations, includes a couple of videos, and culminates with an inquiry-based activity to investigate...

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...

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

Pupils 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.

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

Students investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Students perform a...

Students explore matter by conducting an in class demonstration. In this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't dissolve...

Students analyze earth science by creating a frozen treat in class. In this heat transfer lesson, students discuss how matter is transformed from solid to liquid and liquid to gas when energy is removed from the equation. Students...

Learners explore matter. They use a formula to measure the volume of matter.

Sixth graders investigate ways rice is sold by creating a chart of the different rice foods. In this economics instructional activity, 6th graders examine their local food store and list at least 10 rice by-products in a class chart....

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...

Third graders rotate between three property stations, the solid station, the gas station, and the liquid station. They experiment with each activity until the teacher gives the signal to change.

Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

Students make and test predictions about sinking and floating, and classify objects according to whether they sink or float.
