3.E.4A.3- Obtain and communicate information to exemplify how humans obtain, use, and protect renewable and non-renewable earth resources.

The teacher will start the class by having the students sit at the front of the class on the rug. The teacher will conduct a read aloud using the book, The Lorax by Dr. Suess. The teacher will read the book to the class, then ask the students questions about what they understood from the book. The teacher will have the students get into groups of three and will teach the class about renewable and non-renewable resources. The teacher will pass around 120 goldfish crackers to each group. Each student in each group will play a role during this activity "Over fishing". The roles are the protector, recorder, and fisherman. The protector will take 50 of the goldfish from the beginning and the pond will have 70 goldfish in it. Every round the protector will put four goldfish in the pond, and the fisherman will double the number of fish he "catches" every round starting at "1 fish". The group has to make predictions about how many rounds they will get to before they have no more fish in the pond. This activity shows the students that sometimes humans take more than they need and that we should conserve our resources.

Questions to ask during the lesson:

• What do you think about the overuse of renewable resources?
• How would you construct a plan for your community to help them understand and want to use less natural resources? 
• Do you agree that natural resources are limited and could run out in the future?
