John has decided to study the effects of light on plant growth. He plants 20 marigold plants in 20 identical pots, all with an identical amount of soil.  He waters them the same amount each day. He places 10 plants in a sunny window, and the other 10 in a dark closet.  He lets the plants grow, watering them each day, for 2 weeks.    What is the manipulated variable in John’s experiment?

• Amount of Light
• Type of plant
• Height of the plants
• Amount of water

Sally wanted to know: “Does temperature affect the sprouting of radish seeds?”  Sally planted 100 radish seeds in each of four trays of soil.  The kind of soil, amount of water, and amount of light were constant.  Each tray was kept at a different temperature.  After five days, Sally counted the number of seedlings that had sprouted in each tray. What is the independent variable in Sally’s experiment?

• Number of Seedlings that Sprouted
• Height of the Seedlings
• Temperature
• Type of Soil

• More seedlings sprout at lower temperatures
• Seedlings grow taller at higher temperatures
• More seedlings sprout at higher temperatures
• Seedlings grow taller taller at lower temperatures
