How Hot or Cold? Lab

Purpose: To model how distance from the Sun affects the amount of solar energy

a planet receives.

Materials: tape, graph paper, ruler, flashlight, Sharpie

Procedure:

1- Tape the graph paper to your table.

2- Hold the ruler perpendicular to the

center of the graph paper.

3- Using the ruler as a guide, hold the

flashlight 1.5 cm above the graph paper.

4- Use the Sharpie to trace around the

outside of the circle of light on the paper.

5- Next, move the light to 5 cm above the

graph paper.

6- Again, trace the outside of the circle of

light onto the graph paper.

Questions:

1- What happened to the circle of light when you moved the flashlight farther

away?

Background:

Light leaving a flashlight spreads out just like light from the sun.

Since the same amount of light left the flashlight both times, the smaller circle has

a more concentrated amount of light. Light is a form of energy. Thus, more

energy was received when the flashlight was closer to the paper.
