Student Task: You are embarking on an in-depth investigation of water in your community! You, with help from your group members, are creating a water protection agency-New Haven Student’s Water Protection Agency. As a new civic group, you must gather all the information you can about water in New Haven. You need to have experts on the watershed of New Haven, experts in drinking water legislation, and experts in water treatment.
Challenge: You need to create a presentation answering four questions-where does your water come from, what is in your water, where does it go when you are done with it, and what you can do to protect your water.
Teacher Information: Create groups from 4-6 students and either have students choose their role within the group or choose for them. Each group needs to have “experts” in watershed science, water legislation, and water treatment. Each group is responsible for creating a presentation that answers the above four questions and a plan of action to reduce pollution in New Haven. Students will become experts in their role and teach this information to the other students in their group. Basic information packets should be given to the group for a planning session. At this point the students only have basic information and during this planning sessions the students should come up with questions or make a list of information they will need to become experts in their field. The students should then begin their research. Allow the students time to jigsaw and meet with other experts from different groups. While the students research their area of expertise there will be Discovery Activities that give the students hands on experience.
