Make a Prototype and Test Your Design
Now it is time to make and test a prototype of your design!
Your teacher will provide you with the materials you may use and a sample of contaminated water.
Create your water purification system, and test it out to see how well it works to purify your water sample. Record your observations on page 13 in your Engineering Portfolio and keep track of your data as you test your water purification system.
In this activity, students will build and test their water filtration or distillation systems. Before beginning, have students turn to page 13 of their Engineering Portfolios. Provide students with the directions and materials they will need.
