Is Our Water Healthy?
Students test water for a least one chemical characteristic. They hypothesize how a storm event might change the chemical characteristics of a stream. Students collect water samples and use the chemical test to test the water.

Testing the Waters
Eleventh graders examine a local body of water. In this science lesson, 11th graders collect water samples to test. Students analyze the data and make conclusions. Students create tables and graphs of the data.
Beyond Benign
Urine Jeopardy
Urine can tell us a lot about what is happening in our bodies. In a hands-on activity, scholars administer pH, glucose, ketone, and protein tests to a sample of "urine" solution made from household ingredients. Their results lead them to...

Unit 2 Pre-test, Grades 7– 9
This pre-assessment launches a unit on climate change and weather. 15 questions, both short answer and multiple choice, asses the classes' knowledge about these concepts.
Curated OER
Measuring Aquatic pH
Students apply the scientific method and safety rules to aquatic pH. They test unknown solutions for pH levels.

Soil and Agriculture: Lesson 4 - Agriculture and Soil
Students determine how the various levels of minerals in the soil, as well as the pH of the soil, affect the growth of plants in these plant growth experiments.
Curated OER
Enzymes and Jell-O
Students test for the presence of enzymes in fruit and the specificity of those enzymes. They identify the susceptibility of enzymes to certain environmental factors such as temperature and pH in the enzymes environment.

Move To a Healthier Aquatic Balance
Fourth graders examine aquatic orgnaisms and how enviromental chages affect them. This factors include: temperature, Ph, oxygen, nutrients, and pollutants. They also explore habitat quality (erosion). Students compile data and create...
Curated OER
Acid Rain Research
Students collect samples of rainfall, cloud condensation, and water that trickles through the soil. These samples are tested for pH, conductivity, and the presence of sulfates, nitrates, calcium, and magnesium.

Water Quality
Students examine water quality and how to improve it, how to measure it and how it relates to human activities. For this water quality lesson students sample water from different sources, and test the samples.
Curated OER
Polluted Rain
Students identify and analyze how acid rain can affect the environment. They then explain how air, water, and pollution interact and conduct pH tests to find acidity levels in water. Finally, students become "Pollution Watch Reporters"...
