This STEM lesson about global access to clean water is intended for students in grades 9-12 and is aligned to STEM Standards of Practice, Common Core State Standards and Next Generation Science Standards. The lesson is designed for students to work individually and in groups. Students will conduct research and take notes, design and build a water purification system, and create a presentation to share what they have learned. Teachers will need to guide students through the activities. Some work is designed to be done on the computer and some work is designed to be done in the paper-based Engineering Portfolio.
Before you start the lesson, be sure to do the following:
- Read through the Teacher Notes , which provide a page-by-page companion to the student activities in this lesson.
- Print out and assemble a portfolio for each student and assign teams of 3–4 students, keeping in mind the number of computers your students have access to in the classroom.
