Lesson Length: 1-2 hoursGrade Level: 6-8Students build a water filter with a variety of natural and commercially produced materials. First they test the materials and then choose which to layer together themselves based on material performance. Students learn about water resources and engineered supports for the earth’s water systems and the impacts on environmental and human health. Engineering connections are highlighted throughout the lesson. Special thanks to Giles County, VA STEM Coordinator, Christina Martin, whose unit on The Global Water Crisis was the inspiration for this lesson. Also thanks to the NASA Water Filtration Challenge (https://www.jpl.nasa.gov/edu/teach/activity/water-filtration-challenge/) that helped guide Christina in the development of her lesson.This material is based upon work supported by the National Science Foundation under Grant No. 1657263.

Lesson Length: 1-2 hoursGrade Level: 6-8Students learn about relationships between earth and space including elements of our solar system, gravity, escape velocity, and space exploration though a breakout box experience. They solve clues about space and conditions needed to support life on a planet and perform tests related to space travel. Clues for opening locks on the breakout box are purposefully challenging to simulate the struggle engineers often grapple with when problem solving.This material is based upon work supported by the National Science Foundation under Grant No. 1657263.
