The lesson introduces students to facts about ice ages, including their most likely causes, impact on the earth, and effects on living things. Students likely do not fully understand the meaning of an ice age, or its implications and influences on life on Earth, both past and future. The lesson can be used in conjunction with lessons related to the history of the Earth, glaciers, or the environment.
Sample Classroom Procedure / Teacher Instruction:
- Ask students: What happens to living and non-living things over a long period of time?
- Allow for responses and discussion. Once a student concludes that changes occur, ask students if they know how the Earth has changed over time.
- Allow for responses and discussion. Ask students if they believe the Earth will change in the future, and ask how it will change.
- Allow for responses and discussion. Introduce The Ice Ages.
- Distribute The Ice Ages content pages. Read and review the information with the students. Save the final question for the lesson closing. Use the additional resources to enhance understanding.
- Distribute Activity page. Read and review the instructions.
- Distribute Practice page. Check and review the students’ responses. Allow students to share the corrected false statements, which may vary.
- Distribute the Homework page. The next day, check and review the students’ responses.
- In closing, ask students: Which do you believe is most likely to occur on the Earth first, another ice age or global warming and a “Heat Age”? Why?
- Allow for responses and discussion. There is no correct response, but encourage students to support their responses with facts.
