Scientific Method Test Review

SpongeBob found some Super Bubble Soap at Sail-Mart. The ads claim that Super Bubble Soap will produce bubbles that are twice as big as bubbles made with regular bubble soap. Patrick and SpongeBob made up two samples of bubble solution.  One sample was made with 5 oz. of Super Bubble Soap and 5 oz. of water, while the other was made with the same amount of water and 5 oz. of regular bubble soap. Patrick and SpongeBob used the same type of bubble wands to blow 10 different bubbles. They measured the diameter of each bubble.

Post Malone has taught his pet rat to run a maze. He thinks that the rat will go faster if he puts its favorite treat at the end. He has the rat run the maze ten times with the favorite treat and ten times with a regular food pellet. He uses a stopwatch to measure how long it takes for the rat to get to the reward. What is the dependent variable in this experiment?

• The tyupe of treat

• The size of the rat

• The lenght of the maze

• The time it takes the rate to run the maze
