Students 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.

Seventh graders examine the life cycle of the human. In this human life cycle lesson, 7th graders discuss the many different stages of the human life cycle. Students use pictures from magazines to create a representation of the human...

Students investigate nutrient cycling in a simplified desktop ecosystem involving aquarium and hydro-ponically grown plants. They set up an aquarium with 10 gallons of water at least a week before the lab is planned and place...

A set of guided notes walks your biology or environmental studies learners through the dynamics of ecosystems. They write short answers to questions about the energy budget, food webs, trophic levels, and biogeochemical cycles. One way...

In this cell cycle learning exercise, students review how enzymes control the cell cycle and what happens when the cell cycle becomes uncontrolled. This learning exercise has 7 short answer questions.

What happens at the end of a plant's life cycle? Show kids the natural way that plants show that they're decomposing, as well as the importance of compost, with a lesson about living organisms. After reading Log Cabin by Anne Schreiber,...

Photosynthesis seems nothing short of magic: a little carbon dioxide and water, add energy, and poof, you get food! A thorough, collaborative lesson teaches youth the process of photosynthesis thanks to a skit they perform with a group...

In this food chains worksheet, students complete a crossword puzzle by placing 16 terms into the puzzle that match the clues given. Students review food webs, biomass pyramids, and the water cycle.

Psychologists study human relationships while ecologist study relationships between organisms in the environment. An introduction to ecology and the related vocabulary benefits scholars as they progress through the presentation and...

Students conduct various experiments to investigate plant transpiration. In this biology lesson, students explain how this process helps maintain the hydrologic cycle. They measure the rate of water loss in plants using a potometer.

Students conduct a series of investigations on the unique properties of water. In this general science lesson, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Small but mighty! Learners explore the role of microbes in a healthy ecosystem. An engaging lesson asks pupils to design an aquaponics system that demonstrates that healthy microbes are necessary to maintain the ecosystem.

Roll up your sleeves and get a little dirty with this elementary and middle school compost lesson. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and you're ready...

Students plant seeds, observe and tend plants. They identify major plant parts, how to germinate and troubleshoot problems with plants; and, that plants need water, light, and soil nutrients to thrive. They create a Plant Growth Data Log.

Students identify the changing nutritional needs across the life cycle. They create and prepare a variety of healthy foods for children that provide adequate nutrients for optimum growth and development. They identify guidelines in...

Students explore energy and nutrient flow. In this science lesson, students diagram the flow of energy through food chains and food webs. Students discuss the importance of energy flow in Earth's ecosystems.

Fourth graders explore the plant life cycle. They discuss the sequence of events in the life cycle of the plant and illustrate how the life cycle never ends. Students explore the importance of water, sunlight, and nutrients during the...

Fourth graders complete a worksheet. In this life cycle lesson, 4th graders learn about the leaf cycle and complete a worksheet where they put the leaf cycle steps in the correct order.
