Which tool will best help the student determine if the speed of the mouse improved?

• metric ruler

• pan balance

• stop watch

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...
