This is an activity to accompany a lesson on man’s impact on natural resources. It is to be used with the book, “The Lorax”, by Dr. Seuss. Place a container or cloth on the floor somewhere in the classroom. Fill the container with 5 different items. It could be 5 colors of skittles, 5 types of noodles, 5 types of beans, etc. Tell students that this is a Truffula Tree forest. Split students into 5 groups. Give each group a different type of tree to harvest. Have one student from each group come and harvest their tree from the container for 30 seconds. Students will have a harder time harvesting each time. After the five harvests, have students complete the data chart and reflection questions.
