Unit 4: Considering the Influence of Light and Thermal Phenomena on Global Climate
In this section you will consider a local example of the influence of light and thermal phenomena on a closed system. You also will be documenting some of what you already know about aspects of global climate change.
A. Connecting to relevant everyday experiences
A phenomenon that you may have experienced occurs when light from the Sun shines into an enclosed area.
Question 4.1 What happens when a closed car is parked in the Sun on a sunny day?
- Discuss with your group members experiences you may have had in getting into cars that have been parked with the windows up on a sunny day. Why do you think that happens?
This is an example of a system in which more energy enters than leaves the system. Although the mechanisms differ, the result, an increase in temperature inside the car, is similar to what seems to be happening to the global climate here on Earth.
B. Documenting initial knowledge about aspects of global climate.
Question 4.2 What do you already know about the influence of light and thermal phenomena on global climate?
Document your initial knowledge about the influence of light and thermal phenomena on global climate by responding to the following diagnostic questions. These diagnostic questions focus upon two aspects of changes in global climate: the greenhouse effect and rising sea levels. Your responses will not be graded. You will answer the same questions again near the end of the unit, compare initial and current responses, and write a reflection about changes in understandings and ways these occurred.
