Ei E: Water, Water Everywhere: Designing Water Filters Lesson 3

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Make a splash with young scientists as you teach them all about water using this activity packet. Thirstin, a cartoon glass of water, walks children through the water treatment process, teaches them about different sources of water, and...

Students test a variety of filter materials to see how well they remove particles and color from contaminated water. [10:26]

A storybook introduces the engineering challenge and context. In this story, Salila, a girl from India, learns about environmental engineering as she designs her own water filter. [15:34]

Students focus on the environmental engineering problem of providing clean water as they imagine, plan, create, test, and improve their own water filters. [11:30]

Observe a teacher's lesson, and see her introduce the engineering challenge of designing water filters with a picture book. In this story, Salila, a girl from India, learns about environmental engineering as she designs her own water...

Students think like environmental engineers as they review a mural of a small American community, noting possible sources of pollution and suggesting ways to clean up or eliminate the source of the pollution. [11:08]

This unit offers four lessons demonstrating a classroom working on the engineering problem of providing clean water as they imagine, plan, create, test, and improve their own water filters.

Students learn about air resistance and test three isolated variables used in the design of parachutes. [11:42]

Students explore properties of natural membranes and test the performance of several model membrane materials. [19:02]
