Maggie read that some plants grow better if the soil is acidic. She can’t believe that a plant can grow when exposed to acid. Maggie decides to test if the plants she has will grow better when acid is added to the soil. She puts potting soil in two planting containers and transplants two of her geraniums that seem about the same size into the pots. She puts the pots in the same location so that they both get the same sunlight each day, are at the same temperature and she makes sure they get the same amount of water. However, Maggie puts a tablespoon of vinegar in the water she gives to one of the plants. She measures the growth of the plants every week for five weeks. Identify the independent variable and the controls of the experiment.
Independent variable: Vinegar in the potted plant
Controls: locations, type of plant, temperature, sunlight, amount of water
Igneous rocks can be different because of___________.
What minerals the igneous rocks are composed of?
