Eighth graders make inquiry about the existence of matter. A definition of the word is needed before students can engage in various activities. The application of knowing about matter is done in the working of experiments.

Students list sources of phosphorus in soil. They explain how phosphorus is removed from the soil and used by plants. Students list the symptoms of insufficient or excess phosphorus. Students perform experiments to examine the effect of...

Learners experiment floating a variety of objects in various liquids. They discover how density affects the ability of an object to float and apply the concept of density to solve problems.

Young scholars experience and participate in "Riding the Water Cycle" with this instructional activity. They explore, analyze and study the role of reservoirs in maintaining a reliable supply of drinking water. Each student constructs a...

Young meteorologists answer questions based on the types of weather they experience in the region they live. They also complete a word search to find weather-related terms.

In this Earth's atmosphere worksheet, students observe the effects of air pressure using an egg. They describe what happens to the egg and what makes it do what it does. Then they determine how to get the egg out of the bottle opening at...

Students explore climate change by participating in a physical science experiment. In this greenhouse effect lesson plan, students discuss the impact global warming has on our environment and how it works. Students utilize a glass jar,...

Young scholars observe and experiment using a terrarium. In this scientific lesson plan, students build a nature terrarium. Young scholars then observe their terrarium over a period of time to discover what makes the plants grow. A...

Third graders examine how trees produce oxygen. They examine satellite images of the reservation they examining and interpret the number of trees on the land. They determine how natural resources should be used wisely.
