Students demonstrate the four of five procedures that municipal water plants use to purify water for drinking. A water filtration system is designed by a student and their partner. A data chart is made to record all observations when the...

As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

Students construct a water filter. In this engineering lesson, students discover how to construct a water filtration system. Students work in groups to sort tools by their properties. Students analyze and construct a water filtration...

Students experiment with making a water filtration system. In this engineering lesson, students get into groups and are challenged to use only eight items to create a water filter. When finished, students compare and contrast their results.

Students explore the causes of water pollution. In this environmental lesson, students conduct experiments with natural filtration systems.

Students investigate our water system and how it is filtered. In this science lesson, students perform a laboratory activity to investigate the process that goes into filtering water. They relate this activity to other subject areas...

Learners explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they investigate filtration and aeration processes as they are used...

Young scholars examine various types of household materials for their usefulness as filters. They work together in teams to design a filtration system that produces the cleanest water in the shortest time.

Fifth graders play a game in which they list as many environmental issues or terms in alphabetical order. They brainstorm ways they can save the environment and create a mural that displayed research found from the internet and Encarta.

Students watch videos about unusual fish behavior and write to marine scientists about the proper care of fish. In this fish lesson plan, students watch the videos on how to properly transfer fish to saltwater, and they do so in an...
