1. 12th Grade Environmental Science
Instructor: Ms. Lindsey La Barge
Practice and Presentation: Collecting and Purifying Water
This is the last assignment of the class and I will divide the class into five groups of three. All of the
planning and preparation must take place within the sustainability discussion group folder. I will let you know
what group number you are in and you will be required to join the discussions within that number folder.
Within this discussion, it must be evident that each of the group members is contributing equally. If you have
any questions, please e-mail or page me and I will respond within 24 hours. You can also call me on the
phone between 8:00AM and 6:00PM Monday through Friday.
Project: Each group is to create an apparatus to collect and purify water. Be creative. This is the time to try
any theory that you might have about effectively collecting and purifying water that might otherwise be
unusable. First each group will design a collecting and purifying plan. Then describe the plan in a short essay
with diagrams if needed. Post this essay within the sustainability discussion group folder so that each group
member can read it. The last part of the project is to put the plan into practice. At least one member in each
group is required to build the collecting and purifying apparatus. Extra credit will be given for each extra
group member that builds the design that has been agreed upon. It is required to take measurements of the
water collected and state how the water will be used. Also, take pictures to add to the final presentation.
Presentation: Each group will be required to load a PowerPoint presentation into the sustainability forum by
May 12, 2009 at 5:00PM. This will give everyone a chance to look at and respond to each group’s
presentation by May 19, 2009. Each student is required to respond to all projects, except their own. The
PowerPoint must have notes at the bottom of each slide describing each group member’s participation and
thoughts that were not added to the actual slide. Citations must be added to the slide using MLA format. This
website: http://owl.english.purdue.edu/owl/resource/557/01/ will help you properly format citations. Go to the
bottom of the page and click on the type of source that you need to cite.
Project Grade: Each group member will receive the same grade on the project, so make sure that you do
your part to the best of your ability. I will ask each of you to review the other two members of your group, so
that you can let me know if each person participated equally. Remember that you can get 5 extra credit points
for each extra group member that builds the designed water collecting and purifying system. This project is
worth 10% of your final grade. This project is worth 100 points, but you can get as many as 110 points if your
project meets all the requirements and all team members build the water collecting and purifying system.
