Procedure – Part 2
Congratulations on polluting your water source! Now clean it up. On the table on there are all the materials you need to build a water filter. The people responsible for recording information and gathering materials should go to the table and write down the materials available. When you have the list take one sheet of blank paper and go back to your group.
Read the materials for building the filter to the group. Then as a group draw out a fully labelled water filter diagram. You must use all the materials when designing the filter.
Your group’s drawing must be finished and handed in at the end of the lesson. You have the next 20 to 25 minutes to complete the drawing.
