Students are introduced to the concept of acids and bases and arouse curiosity about acids and bases in daily life. They are introduced to the measurement of soil pH. Pupils are introduced to the effect of soil pH on nutrient cycling...

Learners participate in a series of experiments to learn about plate tectonics and the different materials of the Earth. In this plate tectonics lesson plan, students use eggs, water, beakers, paper, and more materials to learn about the...

Students investigate the lives of frogs by completing several worksheets.  In this biology lesson, students discover the life cycle of a frog from tadpole to death.  Students complete frog life cycle puzzle as well as create a...

In this rain forest worksheet, students use different basic math skills to calculate the percentage of Earth covered by rain forests today compared to fifty years ago. They study the effects of how cutting down trees contributes to water...

Students are introduced to the concepts of a watershed, stream flow and water quality. This five-day plan is an excellent way to introduce students to the concepts involved. They create their own watershed using a paper bag, water and...

Fourth graders observe the effects of water on the soil and record those effect by drawing sketches of water erosion and conservation practices.

Young scholars work together to identify marine debris. They explain the effect of the debris on various ecosystems. They draw different types of ocean currents as well.

Young scholars create their own environment. In this environmental protection lesson, students pretend they are the owners of a tropical island. They create jobs for the citizens and develop the island as a model environment.

Pupils explore the differences in sedimentary, metamorphic, and igneous rocks. They discuss the rock cycle of the different formations. Students discuss how rock is formed into different shapes. They explore, predict, and create each...

Third graders explore water by examining a terrarium.

Students investigate the properties of water. For this states of water lesson, students explore how water goes from liquid to solid and back to liquid again. Students use measurement, observation, and communication to describe the change.

Second graders define condensation and evaporation. They identify and describe the steps in the water cycle. They ask questions to end the lesson.

Students study the Miller-Urey Experiment including its history and criticism.  In this origins of life lesson students repeat this experiment to see how it works.

Students examine the effects of rainfall on different surfaces and discuss water pollution. They review the water cycle and the uses of water in daily lifestyles. Students discuss the effects of soil run off in streams and rivers.

Third graders examine the natural circulation of water from oceans, lakes, and rivers to evaporation into the air, and then to condensation to produce rain falling back to the soil as components of the water cycle.

Students learn about the biological carbon cycle. In this carbon cycle instructional activity, students access the web site and mouse over the diagrams to follow the carbon cycle. They read about what happens to humans and plants during...

Learners investigate the concept of weather and how it is created. They review relevant vocabulary related to weather. Students predict weather given slight background knowledge. The lesson includes background information for the...

Seventh graders take an outdoor observation walk around the campus and take soil samples. Working in groups , they conduct experiments with rocks and soil that demonstrate the effects of different types of erosion.

Second graders discover the needs of their body by trying different types of aerobic exercise.  In this physical education lesson plan, 2nd graders analyze The Busy Body Book by glancing at the pictures inside and predicting what...

Seventy percent of the air pollution in China is due to car exhaust. Under the umbrella of environmental chemistry, learners extensively explore air pollution. From the makeup of our atmosphere to sources of major air pollutants, classes...
