Angle of Sunlight Lab

P. 82

2 of 8

Directions

Hold the flashlight at the correct angle for your test, example 30* and use the protractor to maintain the same distance between your paper and the flashlight for each angle

3 of 8

Directions

Trace the outline of the shape of the light on your paper.

4 of 8

Directions

LABEL the outline with the angle you held the flashlight

30*

5 of 8

Directions

Repeat those steps for the additional angles

30*

Data Collection

​

Column A

# complete squares

Column B

# ½ or partial squares

2

Column C�Approx. total area (A+B)

30* angle

​

​

​

45* angle

​

​

​

90* angle

​

​

​

Then, count the number of complete squares and partial squares and record them in your data table for each tracing mark

Data Analysis

If we assume in our model that the flashlight emits 1,000 kilojoules (unit of energy), how many kilojoules (kJ) will each square receive?

​

​

Column C

Approx. total area (A+B)

Column D

Amount of energy per square

1000 kJ/ Column C

30* angle

​

​

45* angle

​

​

90* angle

Summary of Learning

  1. What do the different angles of the flashlight represent in “real life”? (30*, 45*, 90*)�
  2. Which angle had the highest solar intensity (energy/square)? �
  3. Draw a detailed diagram that helps explain your results from question 2. (labels, etc)

Just REFLECT THE QUESTION
