The Cycle of Matter
An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form.

Amounts of Dissolved Oxygen in Various Bodies of Water
Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...
Curated OER
Oxygen Factory
Fourth graders examine the interdependence of the oxygen and carbon dioxide cycle in an ecosystem through a laboratory investigation. After a lecture/demo, 4th graders complete the lab in groups.
Curated OER
Carbon and Oxygen Cycles
Students construct their own diagrams outlining the pathway of carbon and oxygen in the atmosphere. Students explain their diagrams outlining the pathway and teacher checks for accuracy and completion.
Curated OER
Ecosystems Beneath the Surface
Sixth graders create a KWL chart about microorganisms. In this biology lesson, 6th graders create and label a diagram on a microbial mat. They investigate the processes involved in the carbon, oxygen and sulfur cycles.

The Effects of Photosynthesis on Plant Growth
Students are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...
Curated OER
Trophic Relationships, Cycling of Chemicals, Human Impact on Ecosystems and Conservation
Students explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...
Curated OER
Food Chains
Learners take a look at the relationship between organisms in food chains, food webs, and energy pyramids. After an opening demonstration by the teacher, pupils are split up into groups. Each one is assigned an environment such as:...

Plant Science: Introduction to Photosynthesis
Students explore the process of photosynthesis in plants. They discuss the purpose of photosynthesis and its components. Students discuss the importance of photosynthesis for plants and they examine the parts of the plant that play an...
Curated OER
The Effects of Photosynthesis on Plant Growth
Young scholars examine the process of photosynthesis; its products and reactants, and the sequence of the process. They diagram the light reactions, record observations of plants, and discuss how difficult it is to measure plant growth...
