Along the x axis (across the bottom of your paper) write "Distance of the Flashlight from the surface (inches)".

Along the y axis (along the vertical, left-hand side of your paper) write "Width of the Beam (inches)".

 

Record the data you gathered in the lab yesterday.

 

For example, if the flashlight was 1 inch from the surface, and the beam was 2 inches across, then you would go across your x axis to the number "1". From there you would go up the y axis to the number that is the width of the beam, "2", and place your point on that intersection where the x and y axis meet.

 

Make sure the point you plot on the grid is clear and dark.

 

Once all of your points are plotted, you can use your ruler to join your dots, one at a time, to create a line graph.

 

NOW, take out the worksheet you started yesterday, where you wrote a hypothesis about what you thought would happen.

 

Continue answering the questions down the page using complete sentences and vocabulary directly related to the topic. When you have finished, glue both the graph and worksheet into your science journal on the next two, facing pages. Give the left-hand page the title "Relative Brightness Lab" and add it to your Table of Contents.
