2. Dependent variable:
Alex wants to grow some flowers for his wife, but isn't
sure which flowers will grow best in the soil in their yard.

flowers receive the same amount of sunlight throughout
the day and he waters them all the same amount and at the
same time daily. He records the growth of the flowers
once a week for a month.
3. Hypothesis: Which flowers will grow best
4. Control group:
5. Experimental group:
6. Constants:

Dependent variable: growth of flowers
Independent variable: the type of flower
Constant: amount of sunlight, amount of water, type of soil, time of watering
Hypothesis: IF Lowe's is used, it will grow best in the soil.
Experimental group: Flowers grown
Control group: Flowers not grown
