Are all three cans made of the same material? (circle or highlight one of the following) YES or NO. Does this make the type of material used in the experiment a constant? (circle or highlight one of the following) YES or NO 5. What is the benefit of plotting the data for all three cans on one graph? 6. What is the benefit of plotting the data for when the light is shining on the can on the same graph as the data for when the light is not shining on the can? You may find the following helpful when answering the following questions to use terminology that is often used when analyzing a graph. Directly Proportional relationship: Graph is a straight line that passes through the origin. Linear relationship: Graph is a straight line that does not pass through the origin. Non-linear relationship: The graph is not a straight line, but curves. Increases, Decreases, gradual increase or decrease, drastic increase or decrease, remains constant, increases exponentially. Can you think of more? 7. White can: How does the dependent variable change with respect to the independent variable while the light is shining on the can? 8. White can: How does the dependent variable change with respect to the independent variable when the light is not shining on the can? 9. White can: Compare and contrast the behavior of the dependent variable with respect to the independent variable when the light is shining on the can, and when it is not shining on the can. 10. Gray can: How does the dependent variable change with respect to the independent variable while the light is shining on the can? 11. Gray can: How does the dependent variable change with respect to the independent variable when the light is not shining on the can? 12. Gray can: Compare and contrast the behavior of the dependent variable with respect to the independent variable when the light is shining on the can, and when it is not shining on the can. 13. Black can: How does the dependent variable change with respect to the independent variable while the light is shining on the can? 14. Black can: How does the dependent variable change with respect to the independent variable when the light is not shining on the can? 15. Black can: Compare and contrast the behavior of the dependent variable with respect to the independent variable when the light is shining on the can, and when it is not shining on the can. 16. Does your data support your hypothesis? Explain your results
