4.
Read the description of the experiment below. Fill in each part of the scientific method for the experiment.
Ms MacAulay wondered this. She thought back and realized the summer was rainy, and thought that
all the extra water caused the cucumbers to be very small.
Hypothesis:________________________________________________
To test this, she set up 4 pots of cucumber plants. One she watered a normal amount-50 mL of water
per day. The other three she gave:
100 mL, 150, mL, 200 mL of water.
Control:________________________________________________
Independent variable:________________________________________________
Dependent variable:________________________________________________
She measured them every other day for one month, and found that the plant with 150 mL of water and
200 mL of water were 8 cm smaller!
Results:___________________________________________________________________________________________
___________________________________
She decided that she was correct and would water her cucumber plants less next year if the summer
was rainy.
Conclusion:_______________________________________________________________________________________
