FCAT Science Sample Questions
Kevin hypothesized that dark colors absorb more heat than light colors. He put equal quantities of water in a can covered with black paper and in a can covered with white paper. Kevin measured the temperature of the water in each can at regular intervals on several sunny days. He constructed a graph to display the average temperature of each can over the course of his experiment.
