A scientist is conducting an experiment to test the effect of the amount of sunlight on plant growth. What is the dependent variable?
Plant growth
Amount of fertilizer
Amount of water
Amount of sunlight
Which of the following is a valid hypothesis?
After conducting an experiment, Susan states that sunlight definitely alters the pH of water.
Does an increase in sunlight affect the pH of water?
Susan suggests that an increase in sunlight can increase the pH of water.
Susan states that an increase in sunlight will definitely increase the pH of water and causes fish to die in the pond.
Based on the graph “Effect of Light on the Height of a Plant” what relationship would exist between the variables?
An increase in the height of a plant will increase the amount of sunlight
As the amount of sunlight increases, the height of the plant decreases.
As the amount of sunlight increases, the height of the plant remains relatively constant.
As the amount of sunlight increases, the height of the plant increases.
