Water Monitoring and Pollution

Do golf courses affect the water organisms in nearby streams and ponds? Small groups collect samples of water upstream and downstream from a golf course and analyze the macroinvertebrates found and the stream index values of the two...

What kind of organisms are living in the stream? After an explanation on how to use a dichotomous key, groups of three to four use the keys to identify macroinvertebrates from a local freshwater stream. Using the the concept of Stream...

Did you know that California produces two thirds of the fruits and nuts consumed in the United States? That it produces almost one third of the vegetables? Did you know that scientists warn that California is facing the onset of a...

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

In this water contamination investigative worksheet, learners identify a fictional local business that is continuously contaminating the water. They role play as a member of the consulting firm as outline the evidence that they would use...

Tenth graders research two ways to test the water quality near their home. For this chemistry lesson, 10th graders determine the short and long term effect of different substances on aquatic ecosystems. They conduct tests and write a...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Healthy invertebrates mean healthy ponds. An outdoor activity has scholars collect samples of invertebrates from local lakes or ponds. They identify and count different species and use the information to estimate the level of pollution...

Students become familiar with real-world gathering of chemical data. The experience how the science is done: the nature of analysis, data collection, interpretation, and presentation. They study a nearby body of water for their experiment.

Students 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.
