Aquatic Field Data
Students use laptops and sensors to measure water quality and graph their results. In this aquatics lesson students post their results to a website or email.
Curated OER
Technology as a Tool of Science
Students monitor streams, take stream surveys, collect chemical and macro-invertebrate and stream discharge data. Using a digital camera, students observe the percentage of various types of vegetation on the flood plan, riparian area and...

Water Hardness- Causes and Testing
Eighth graders examine what materials cause water hardness and the relative measure of water hardness in a two part lab activity. In part one, 8th graders add an assigned soap test solution to eleven different test tube solutions in...
Curated OER
Science: Dissolved Oxygen and Water Quality Sampling
Students perform tests to determine the level of oxygen dissolved in water. After examining a table displaying the temperature and solubility of water, they examine the three stages involved in the test. Upon completion, students explain...

The Effects of Water Quality on the Growth Rate of Freshwater Mussels
Pupils participate in a field and laboratory study to determine if local freshwater mussels are environmentally stressed.
Curated OER
How To Get Clear On Water
Tenth graders investigate different systems that are used to purify water. They have class discussion about the benefits and challenges that different countries would face with the implementation of the systems. Students explain the...
Curated OER
Where's the Water?
Fifth graders conduct an investigation into water purification during a role play situation in an Amazon Rainforest. They design a scientific experiment for cleaning and filtering water.
Curated OER
Analyze the Results
Students conduct water tests and sample macroinvertebrates from a nearby source to make a general determination about the overall quality of water. They use worksheets and analyze data as part of a larger unit.

Aspirin Analysis
Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand.
Curated OER
What's in the Water?
Students examine water data for up to a month and perform tests on the samples.
