DistancesRecommendations

• 20 cm distance from the light- Take temperatures at 5,10 and 15 minutes

• 50 cm distance from the light

- Take temperatures at 5,10 and 15 minutes

• 80 cm distance from the light

- Take temperatures at 5,10 and 15 minutes• Convert all units to metric ( conversion

Learning Objectives

By the end of this activity, students should be able to:

•Describe an equilibrium temperature.•Identify the factors leading to an equilibrium temperature.•Relate the temperature of an object to the energy it emits.•Relate the temperature of an object to the reflectivity of its surface.•Identify major energy inputs and outputs of a system.•State and apply the Law of Conservation of Energy.•Qualitatively relate “distance from the source” to the “energy incident upon an•object.”•Describe relative strengths and limitations of physical and computer models.

Materials needed for Activity B

•A Windows or Apple based PC

•A web browser enabled with Java Version 1.3 or higher (Any Mac with OS X version 10.2 or better will include Java 1.3. Windows users may have to download and install the runtime version of Java from http://www.java.com/ . You will need Administrator rights for this installation.)

• The courseware (a Java applet) loaded into your web browser: available at http://icp.giss.nasa.gov/education/modules/eccm/model/ – see Education Tools, Earth Climate Course Computer Models for Module 1.

NASAExplorerSchools Engage

1. Start by limitations of physical model used in previous lessons.

- What would have happened to models if room temperature was changed?

2. Discuss outcomes.

NASAExplorerSchools

NASAExplorerSchools


Because the temperature of the models (or other systems) remains constant, what must be true about the energy inputs and outputs of the system?

What happens to the energy going into the system?

Variables students can control

NASAExplorerSchools

You Try It!When the web tour opens do the following:

• Run the simulation with the default variables by clicking the ‘start’ button.

• Change each of the variables – room temperature, reflection coefficient, source power and distance, one at a time, then start again and see what happens.
