Tina asks the question “Does caffeine increase the heart rate of an earthworm?” In Test 1, she measures the heart rate by looking at the earthworm under a microscopes, the earthworm has a heart rate of 50 bpm (beats per minute). In Test 2, she places a few drops of caffeine on the earthworm’s skin and measures the rate again. In this test, the heart rate is 68 bpm. 1) What is the manipulated (independent) variable in this experiment? 2) What is the responding (dependent) variable in this experiment?
What is 1) caffeine and 2) heart rate?

ordan is doing a science fair project on the effects of music on the growth of tomatoes. He has two tomato plants, Plant A and Plant B, that he grows in a window and gives the same amount of water. Plant A is exposed to classical music using headphones attached to the soil. Plant B is not exposed to music. Throughout the growth period, Jordan counts the number of tomatoes produced by each plant. Plant A = 35 Tomatoes | Plant B = 55 Tomatoes 1) What is the control group? 2) What is the manipulated variable?
What is 1)group B and 2)exposure to classical music?
