A scientist investigates the effect of carbon dioxide on plant height. The scientist grows plants in several closed containers. All the plants receive the same amounts of water and light, but the air in each container has a different amount of carbon dioxide. What is the independent variable in this experiment?
the amount of carbon dioxide in each container
the number of plants in each container
the amount of water provided to the plants
the height of each plant after a period of time
Researchers are developing a new fertilizer designed to improve the growth of endangered Hawaiian plants. The fertilizer was applied to one hundred plants in a greenhouse. The temperature, humidity and amount of water were kept constant. Which is best for the researchers to do next?
compare plants that received fertilizer plants that received none
begin selling the fertilizer to gardeners living in hot, dry climates
change the conditions in the greenhouse and retest the fertilizer
test the fertilizer on plants that are adapted to cooler climates
