RET Teaching Module 21: Filters, Lights, and Entrepreneurship

Overview

Students will design and improve water filters using the engineering design process. Students will also build a spectrometer to support understanding the function of light to test different materials.

After completing this module, student should be able to:

• define engineer
• identify and implement the steps of the Engineering Design Process
• discuss some problems and engineering solutions associated with air, water, and soil contamination
• recognize the role of environmental engineers in helping to address the problems of air, water, and soil contamination
• identify multiple human uses for air, water, and soil
• make predictions about the efficacy of different filter materials based on their properties
• conduct a controlled experiment
• observe, analyze, and compare the performance of filter materials when used to filter contaminated water
• decide which materials and/or combination of materials will be good choices for use in a water filter design
• use prior analyses of filter materials to inform their water filter designs
• test and analyze a water filter design for strengths and weaknesses
• "improve" their designs based on earlier analysis
