This lesson offers activity ideas and discussion questions to facilitate students learning about the phases of the Moon. In this lesson, students explore how living things are affected by changes in the environment by studying the case of the snowshoe hare and how it’s impacted by climate change. Why you sometimes feel a cold coming on, only to have the symptoms disappear the very next day. To develop the idea that carbon dating is based on gathering evidence in the present and extrapolating it to the past. Students will use a simple graph to extrapolate data to its starting point. For the laboratory portion of this lesson, you will have to set up the ring stands, rings, funnels, and graduated cylinders. Fill the funnels with ice before the students arrive in the classroom. You can continue to fill the funnels as different classes arrive.

Empty the graduated cylinders between classes if the volume is more than about 75 ml. Begin by having students read the article.
The article briefly describes radio carbon dating. Students should answer the questions on their student sheet based on their graphs and the data they collected.
