The Cycle of Matter
An educational instructional activity 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.Â
Curated OER
Evolution and the Fossil Record
Engage young biologists with four laboratory activities that explore the fossil record. Learners examine fossil images, a fossil kit, the rock record, and geologic time scale. They even experiment with the oxygen production of an Elodea...

History's Thermometers
Ancient coral beds give scientists clues to past ocean temperatures in much the same way that tree rings indicate historical weather conditions. High school scientists examine coral oxygen isotope ratios and plot the data as a function...
Curated OER
Fortified Breakfast
Students reverse engineer a cereal. In this dietary instructional activity students identify the minerals that the human body needs to function. Students examine how foods are fortified by food engineers. Students find the amount of iron...
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
Oxygen Levels and Aquatic Plants and Animals
Students design an experiment to test the effects of a change in the amount of dissolved oxygen of water on aquatic plants and animals. Questions are offered for exploration and experiment design. Results are tabulated and conclusions...
Curated OER
Monitoring Oxygen Level
Students measure oxygen percentages in room air and air exhaled after they perform various activities. They explore various websites, and record and analyze the data from the experiments.
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
Water: The Neutral Substance
In this water worksheet, students read about hydrogen bonds in water and the differences in electronegativity between the oxygen atom and the two hydrogen atoms in water. Students answer four questions about the structure of water and...
Curated OER
Oxygen: What a Gas!
Eighth graders explain how oxygen reacts to other elements. They also explain why oxygen is a reactive substance, how it has weight, and how it reacts with other substances. They construct an experiment to relate their findings.
National Institute of Open Schooling
p-Block Elements and Their Compounds – II
Ozone, made of three bonded oxygen atoms, is found 15-30 km above Earth, has a strong smell, is blue, and blocks sunlight from hitting the surface of Earth. The 22nd lesson in a series of 36 specifically focuses on the important elements...
University of Washington
The Carbon Cycle
When it comes to the carbon cycle, the sky really is the limit. The lesson begins with observing a closed ecosystem in a bottle. Then, scholars discuss and answer questions on the carbon dioxide and oxygen cycles.Â
American Museum of Natural History
Journey to the Bottom of the Sea
Follow the path to the sea floor. Pupils play an online interactive board game to reach the bottom of the sea. Participants must match descriptions of creatures to a property of water dealing with oxygen, food, light, or density to move...

Dissolved Oxygen in an Aquatic Ecosystem
High schoolers explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.
Curated OER
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...
Curated OER
Environment: Battling for Oxygen
Students construct an interactive ozone depletion model using gumdrops and toothpicks. After analyzing the data obtained from the model, they record it on butcher paper and complete worksheets about oxygen.
Curated OER
Space Shuttle Science
Students study the nomenclature, operation and purpose of America's Space Transportation system. They demonstrate how water can be broken down into its component gases of hydrogen and oxygen by electrolysis. They construct and use the...

Laboratory: Observing a Candle
In this observation worksheet, scientists observe a burning candle and answer eight post-lab questions. Topics include the phase changes occurring during the observations, the role each part of the candle plays in the chemical reaction,...
Curated OER
Photosynthesis: Intake of Carbon Dioxide - Production of Oxygen
Students, after a long-term observation of photosynthesis with aquatic plants, assess the benefits of photosynthesis towards all living organisms. They explain in their own words the two cycles within photosynthesis. Guided discussion...
Curated OER
Dissolved Oxygen
Students discuss the relationships between dissolved oxygen in a stream, stream temperature, organic waste loads, and stream conditions by studying and using a model of dissolved oxygen in the stream.
Curated OER
Fish and Oxygen
Students explore what factors affect population dynamics, identify factors affecting fish populations, and use Stella to model how dissolved oxygen affects fish populations.
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.
