Curated OER
Nitrogen Cycle-Stream Side Science
A thorough background and nitrate sampling lab sheet are provided to share with your young scientists. After discussing the nitrogen cycle with the class, you will break them into small groups and show them how to use their inquiry...
Curated OER
The Nitrogen Cycle
Students design and create a compost pile in order to study the Nitrogen Cycle. They then use the scientific method to determine if plants grow better when they add organic matter from their compost pile to the plant's soil.
Curated OER
Microbial Influence on Earth's Systems
Students identify the different biogeochemical cycles on Earth. In this biology lesson, students observe microbes under a microscope. They compare and contrast respiration and photosynthesis.
Curated OER
Let's Make a Compost Cake
Students create a compost cake. In this gardening and decomposition science lesson plan, students review and describe the "nutrient cycle." Students create a compost pile, measure and record the dimensions and temperature of the pile,...
Curated OER
Weathering
Second graders explore weathering and how the water cycle plays a part in weathering. In this weathering lesson, 2nd graders put gravel and sugar cubes in a jar and shake, simulating weathering. Students use the scientific method to do...
Curated OER
Can't Bayou this Water Cycle
Learners identify the stages in the water cycle. They observe a local water source and view the cycle in action. They create their own water cycle using software.
Curated OER
Microbes in Long Island Sound
Students discover the harm and benefits of microbes. In this biology lesson, students explore water, nitrogen and carbon cycles. They investigate the factors affecting bacteria growth.
Curated OER
Ions in the Environment
Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
Curated OER
Go With the Energy Flow
Students explore energy and nutrient flow. In this science activity, students diagram the flow of energy through food chains and food webs. Students discuss the importance of energy flow in Earth's ecosystems.
