Ashley wanted to determine the effects of a soil pollutant on the growth of a sunflower plant. She
designed an experiment and recorded her results in the data table.
1. According to this experiment list 3 constants.
a. _water___________ b. ___sunlight________________________ c. __plant_________________
2. According to this information, what is the dependent variable?__height of the plant____
3. According to this information, what is the independent variable?__pollutant______
4. Write a hypothesis in an (If… then) statement for this experiment.
If the amount of the pollutant increases, then
the height of the plant will increase.
