Teachers explore patterns in sunspots and total solar irradiance to understand the counterpoint to the human effect of global warming. In this professional development tool, teachers work through a lesson on the sun's natural...

Students plan, practice, and act in a 2-3 minute videotaped production about a specific topic. Students from a local high school give presentations pertaining to seasons, earth rotation, and moon phases. Students analyze the...

Walk your class through the journey water takes once it leaves your kitchen sink, all the way through the water cycle. Demonstrations support your lecture. This plan is thoroughly written, but ideally you would follow it up with water...

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 study different bodies of water and how they fit into the water cycle. They explain that materials exist in different states (solid, liquid and gas) and change from one to another, that there are systems, order, and...

Students experience and participate in "Riding the Water Cycle" with this lesson. They explore, analyze and study the role of reservoirs in maintaining a reliable supply of drinking water. Each student constructs a model of a reservoir.

Pupils access prior knowledge of the water cycle by completing a KWL. In this water cycle instructional activity, students follow the movement of water through the water cycle.

Purifying air and water, providing soil in which to grow crops, and moving water through its natural cycle are all services an ecosystem provides that benefit humans. Lesson four in a series lets learners explore and discuss the value of...

Caterpillars have an amazing, yet tough job to perform in their short lives — eat much, avoid predators, and try not to let all those comments about being the unattractive stage of the life cycle get to them. How do they handle it all?...

Students are introduced to the water cycle and water movement in soil. For this water cycle lesson, students explore how water moves through the water cycle and discuss water sources, natural reservoirs, soil...

In this life cycle workbook, 3rd graders complete several different activities in which they analyze different invertebrates, identify arthropods, examine human biology and plants, and study natural environments. 20 different activities...

In this carbon cycle lesson plan, middle schoolers review the carbon cycle and visit stations in the room where they experience every phase in the carbon cycle. Students journal about their journey through the cycle and brainstorm...

Fifth graders identify the chemical and physical changes in the water cycle, carbon cycle, and the effects of weathering. They analyze the periodic table, and observe how vinegar reacts with limestone in a chemical reaction that causes...

Students investigate the life cycle of the 'o'opu also known as Hawaiian gobies.  In this amphidromous living lesson, students discuss the reproductive cycle, create props and an obstacle course to demonstrate the importance of the...

Students examine human impacts on the water cycle. They compare/contrast the permeability of various materials for the purpose of engineering landscape drainage systems, and answer discussion questions.

Students study the formation of metamorphic rock. In this metamorphic rock lesson, students examine how metamorphic rock forms as part of the rock cycle. They review the rock cycle using chocolate chips, conduct Internet research, and...

In this water cycle instructional activity, 3rd graders conduct an experiment where they observe and calculate how water transpires in different types of trees.  Students engage in a class discussion and use Venn Diagrams to compare...

Students investigate the stages of plant life. Students create a K-W-L chart. They describe six main stages of the plant life cycles. Using stickers, students create a life cycle flow map.

Second graders explore biology. In this life cycle instructional activity, 2nd graders act out the stages a caterpillar goes through to become a butterfly. They spend days prior to this instructional activity observing caterpillars they...

Second graders will study and explain the meaning of growth, development, and life cycle. They describe how plants grow and develop and observe an animal to show how it grows, changes, and reproduces throughout its life.

Students examine the rock cycle and how rocks can change over time.  In this geotechnical engineering lesson students draw a diagram of the rock cycle.

Students participate in a mini field trip around the neighborhood to observe nature and changes that are occurring during fall. They collect leaves of various colors, shapes and sizes on their trip. Upon return to the classroom, they...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...
