Ecology 5 - Carbon and Oxygen Cycles
Students construct their own diagrams outlining the pathway of carbon and oxygen in our atmosphere. They listen to a lecture on the carbon cycle while drawing an example of the carbon cycle on the board. Students comprehend that CO2 is...
NASA
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.
Curated OER
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
The Biological Carbon Cycle
Students learn about the biological carbon cycle. In this carbon cycle lesson, students access the web site and mouse over the diagrams to follow the carbon cycle. They read about what happens to humans and plants during this cycle.
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 instructional activity, 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
Nitrogen Cycle
Students identify the main concepts and ideas of the nitrogen cycle.
They review key concepts covered up to this point in ecology including food chains, food webs, energy pyramids, and bio-geochemical 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
Dissolved Oxygen Lesson
Students investigate what dissolved oxygen is and why it is important to aquatic life and what factors influence levels of dissolved oxygen in a lake. They study how to use MS Excel to make charts to show trends and correlations.
Curated OER
Food Chains
Fourth graders investigate food chains. They review cycles and discuss ecosystems. They select an environment and create a food chain in small groups. They write their food chain and label it for the class to evaluate. They create...
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...

Ecology 12 Human Effects
Students are able to respond to a reading passage concerning human effects (under development) in Madagascar. They have a quiz on primary and secondary succesion as their bell ringer. Students write an essay on the topic "No man is 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...
