Curated OER
The Science of Respiration and Blood Circulation
Fifth graders study how respiration and circulation are connected. In this respiratory instructional activity students complete several activities to better understand heart rate and carbon dioxide in the body.
Curated OER
The Dose makes the Poison
Learners investigate the effect of a chemical (they choose) on the germination of seeds. They calculate % chemical concentrations in water, form a hypothesis, and discuss the ethics of using animals in biomedical research.
Curated OER
Tobacco Smoking and Lung Cancer
Students explore tobacco smoking and the impact it has on society. In this health lesson students complete several experiments on smoking and lung cancer.
Curated OER
The Chemistry of Lead
Learners explore the basic concept of physical and chemical properties of the element lead, as well as its historical and modern day uses, and how and why it is toxic to the human body. They are shown the basic reactions of the element...
Curated OER
Love Canal-A Man Made Disaster
Students watch a "Waste Management" Power Point as well as a "Love Canal" PowerPoint (a link is provided for the second presentation). Students write the chemical formula for each chemical and convert the contamination to grams using...
Curated OER
Fertilizers, Pesticides and Health
Pupils apply real data to create and calculate algebraic equations. Students create a visual to represent the concentration for one part per million and apply unit analysis to verify measurement computations. Pupils define the use of a...
Curated OER
Science: Testing Water for Toxicity
Students investigate the potential toxicity of water samples using California blackworms to test water quality. They observe the worms' behaviors in different water samples and determine which sample has the highest toxicity. At the...
Curated OER
Dose-Response Relationship
Students complete their observations of germinating seeds. They create a graph showing all of their data and develop a dose-response curve. They compare their data with other groups and analyze the curves.
