He bought a Special Flower Power fertilizer to see if it will help plants produce more flowers. He plants two plants of the same size in separate containers with the same amount of potting soil. He places one plant in a sunny window and waters it every day with fertilizing water. He places the other plant on a shelf in a closet and waters it with plain water every other day.

have any acid rain added. All 10 pots were set on the window to receive the same amount of sunlight and was watered the same amount of water at the same time everyday. After 5 days, germination rates were recorded for each pot. What is the dependent variable? - correct answers ✅Germination Rate Students wish to test the effects of acid rain on the germination of a seed. They added different strengths of acid rain to radish seeds. They had 10 pots of soil and added 3 radish seeds to each pot. Pots #1-9 had different concentrations of the acid rain added to them. Pot #10 did not have any acid rain added. All 10 pots were set on the window to receive the same amount of sunlight and was watered the same amount of water at the same time everyday. After 5 days, germination rates were recorded for each pot. What are the constants? (list at least 3) - correct answers ✅Sunlight, Water, Amount of seeds planted Students wish to test the effects of acid rain on the germination of a seed. They added different strengths of acid rain to radish seeds. They had 10 pots of soil and added 3 radish seeds to each pot. Pots #1-9 had different concentrations of the acid rain added to them.

What is the control group? - correct answers ✅Pot # It is January and Haley, Sarah and Becky are tired of having cold feet while waiting for the school bus to come in the morning. They decide to design an experiment to test the effectiveness of wool, cotton and nylon as insulators. They fill identical bottles with 200 ml of water at 100C and place inside each sock. They take the temperature of the water after 20 minutes.
