Learners calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.

Students are introduced to the SWMP system which tracks short-and long-term changes in water. Using this data, they plot and interpret the data on a graph to determine how human activities are lowering the water quality. They also...

Ninth graders investigate relationship between the temperature and concentration of dissolved oxygen in water. They examine how pollution and other natural influences can cause the parameters to change. In groups, 9th graders collect...

Eighth graders discuss the different types of ecosystem. In this earth science lesson, 8th graders explain the benefits and harm of fire. They research articles about bush fires or controlled burn instance and share it with the class.

Learners predict the movement of an air borne pollutant using their understanding of air currents. They determine which governments and/or communities should be contacted to be forewarned. They also explore the properties of their...

If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this...

A slide show serves as the backdrop for a instructional activity on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

In this Dalton worksheet, students read about John Dalton and his contributions to understanding the atom. Students are given sample data for Dalton's experiments and they answer questions about the data in his experiments.

Mutation and auxotrophs are discussed. Next, the details of RNA transcription and how enzymes can control splicing and introns are given.

Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water.
