Building a Filter

Have you ever thought of how water gets to our faucets? Nano particles and filter materialWater is pumped from lakes into water treatment plants. This water is filled with contaminants. Contaminants are materials that make water unsafe to drink. Leaves, algae, sand, salt, and bacteria are examples of contaminants. These contaminants may differ in size, chemistry, and other ways. These differences make water treatment a complex, multiple step process. Since dirty water contains many contaminants, engineers are always researching contaminants and designing ways to remove them from water. The water treatment process provides clean, safe water to drink.

Building a Filter TEK8 Student Guide

The student handout will be given to all students working on the design challenge. It gives a brief recap of the story, it helps the students identify what they are attempting to achieve, and it recaps the design process.

Building a Filter TEK8 Instructor’s Guide

This Instructor’s Guide provides the instructor additional information on how to run the design challenge with alternatives for materials and test setups as well as information to help make the design challenge a good educational experience.

Telling the Story Video

The Telling the Story Video conveys the societal impact of the student’s research that is the basis for the design challenge and will set the problem-solving context for students.

Design Challenge Video

The Design Challenge Video leads students through the design process. It indicates materials available, states what the criteria are for success and any constraints. It also gives a second ‘level’ of the design challenge that allows ‘early completers’ to move on to a slightly more difficult challenge.

PowerPoint Presentation

The presentation can be used in conjunction or in place of the Design Challenge Video.
