Developing Tests to Distinguish Between Similar-Looking Liquids
Each group talks about how to test unknown liquids based on their findings in the previous experiment. In this second of four activities, they test unknowns on wax paper, newspaper, and construction paper. As a stand-alone, this lesson...
Curated OER
Bats and Hot Dogs
Students identify patterns and relationships from data that is collected and solve variables. In this investigative lesson students study ocean productivity, the nitrogen cycle and phytoplankton then answer questions.
Curated OER
Shake, Rattle and Roll
Students compare the weathering of different-sized materials. Comparisons are made and data analyzed to reach conclusions about the process of weathering. Applications can be made for the higher grades.
Michigan Sea Grant
Water Quality
Learners observe water samples and measure the samples' water quality. Students develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.
Curated OER
What Is In The Water?
Learners investigate the biotic and abiotic factors that are found in an aquatic ecosystem. The emphasis is upon the investigation of present an projections of future water quality. Then students visit a local body of water to gather...
