The front of the two versions are identical but the reverse sides have different information. The authors suggest displaying one and cutting the other into sections for use in various activities. One activity described in the guide addresses the topic of hazardous wastes in terms of where they come from and where they go. The students begin by brainstorming and then build models with sand, cornstarch, salt and sodium bicarbonate to demonstrate how the waste gets from the ground into the water. At the end of the activity, the students test the water to find out whether wastes are present.
Highlighted boxes contain materials lists and questions related to the activities.
A list of additional resources is included in the guide.
