Curated OER
Water Quality Monitoring
Young scholars study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.
Curated OER
Pesticides and Eggshell Thinning.
Students analyze the calcium content of egg shells as an introduction to the toxic effects of pesticides on biological systems.
Curated OER
Identification of Different Compounds and Substances
Students conduct a series of tests to identify unknown compounds. In this chemistry lesson, students compare the physical and chemical properties of substances. They collect data and formulate a conclusion.
Curated OER
What Happens When Chemical Are Put Together?
In this chemical reactions worksheet, students answer 20 multiple choice questions about chemical equations, chemical formulas, oxidation and reduction reactions and acids, bases and salts.
Curated OER
Dewey and Chemistry: The Water Cycle Revisited
Students undertake a series of experiments related to the water cycle. All experiments use John Dewey's experiential philosophy as their bases. Each lesson is clearly based on philosophy and attempts to be relevant.
Curated OER
Amino Acids
Students explore what amino acids are, their history and how they are used in technology. In this protein lesson plan students identify the properties of proteins and amino acids.
Curated OER
A Self Directed Inquiry into the Identification of Unknowns
Learners gain experience in designing an experiment and use logic in selecting specific tests for unknowns. Students recognize the use of spreadsheets in helping one to make clear comparisons.
Curated OER
Seltzer Breath
Young scholars investigate "indicator" (Bromothymol Blue or BTB) to test for the presence of certain chemicals in liquids and gases. They compare distilled water and seltzer water for presence of carbon dioxide.
Curated OER
Water Quality Monitoring
Students work together to gather water samples. They compare and contrast the water quality from different places in the community. They answer discussion questions to complete the lesson plan.
Curated OER
Jeannette
Pupils develop hypothesis about what might happen when salt water is frozen. In groups, they freeze ice samples with different salt concentrations. They use the internet to research the situation of the Jeannette to discover their answer.
