Learners investigate, through their own experimentation, the important role wildlife play in nutrient cycling. Earthworms and compost are used in this experiment and different experimental setups be evaluated.

Ninth graders investigate evolution via natural selection and form an opinion. They support their opinion using scientific evidence and apply this to adaptations that have allowed certain organisms to survive.

For use early in the year with your ecology class, this collection of slides introduces viewers to cycles in nature and relationships between organisms. There is a food web diagram, but the presentation is incomplete without any diagrams...

First graders examine the lifestyle of classroom and family pets in their natural habitat. They determine the needs of plants and animals, and how those needs are met. They listen to read alouds, sing songs, and draw using computer based...

An interactive lesson places pupils as scientists who must learn why the ozone layer is being destroyed by analyzing the data from multiple satellites. The first analysis shows how UV is related to the ozone cycle. The second...

A change in a parameter can end in overpopulation. The resources gives pupils the opportunity to control the parameters of rabbits and wolves in a natural setting. Using the set parameters, the simulation runs and displays the population...

Students explore decomposition and soil health by creating their own garden.  In this agriculture lesson, students build a "lasagna garden" with organic matter found in the area and plant perennials native to their region....

Fifth graders examine the carbon cycle, periodic table, and photosynthesis and respiration. They analyze the periodic table and how it is organized, then complete the "Elementary, Dear Watson" worksheet. Students then examine a carbon...

Seventh graders learn how trees help nature recycle.  In this carbon cycle lesson, 7th graders view a picture of a giant redwood tree, complete a Think, Pair, Share activity, view and discuss a poster about how nature recycles,...

Students explore the natural distallation process that occurs in the water cycle. They use plastic cups and cotton swabs to observe the condensation process that is evident in the water cycle.

Students are introduced to the terms related to the water cycle in their native language. In groups, they describe the steps of the cycle using different materials found in their art classroom. They describe how energy helps water...

Second graders use the program HyperStudio to draw and describe the water cycle. In this science and technology lesson, 2nd graders will first become familiar with the water cycle by exploring books and websites in the classroom. Next,...

Young scholars are introduced to the components and importance of the water cycle. They are shown how groundwater moves using a model. Students list 9 places on earth where water is found. They define the terms cycle and water cycle.

Students develop a better understanding of the need to conserve our renewable resources.  In this water cycle lesson students take notes, complete a guide sheet and illustrate the water cycle. 

Third graders investigate the stages of animal life cycles. They examine an egg and compare it to an inanimate object, read a booklet about the life cycle and define key vocabulary terms, and observe a mealworm. Students then design a...

Students take an imaginary journey through the water cycle. In this water cycle instructional activity, students identify the various parts of the water cycle, listen while their teacher leads them on an imaginary journey through the...

In this researching the nutrient cycle worksheet, students read about the cycle of nutrients, look at the diagram, then answer two questions by doing research on this topic.

Students investigate natural resources and man-made items. In this earth science lesson, students classify items from trash into man-made items or natural resources. Students construct a flow chart to investigate the life cycle of a...

Students participate in various air experiments to understand that air is all around us. In this states of matter lesson, students focus on the role of air in the water cycle. Students understand that air is densest near the ground....

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 explore the life cycles of insects and how they interact with each other in the prairie to create a healthy ecosystem and viable food chain. They list animals or insects in their own community that are similar to the prairie...

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...
