Curated OER
Oxygen-Carbon Dioxide Cycle
Fifth graders observe a diagram of the oxygen-carbon dioxide cycle to know that when they breathe out, they exhale carbon dioxide as do animals. They observe an aquarium containing both plants and fish and discuss the cycle. They then...
Curated OER
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
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
The Nutrient Cycles
Students investigate the circle of sea life by creating nitrogen compound models. In this oceanography lesson, students discuss sea creatures and where their waste goes. Students identify nitrogen cycles in the ocean by viewing...
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.
Curated OER
The Effects of Photosynthesis on Plant Growth
Students 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 as it...
