For his science project Sam decided to test the effect of a vitamin on the growth of
radish seeds. Sam thought that if vitamins helped the nutrition and growth of humans, then
vitamins would help the growth of the radish seeds by making more of the seed sprout. Sam
planted 5 radish seeds in 100 grams of soil and added 10 ml of water to the soil. In his second
group, Sam planted 5 more radish seeds in 100 grams of soil, but this time he crushed a
multivitamin and dissolved it in 10 ml of water, then he used the vitamin water to water the
second set. Both groups were placed by a sunny window. After one week, Sam observed that
only one radish seed in the vitamin solution germinated (sprouted) and that four out of five seeds
in soil with plain water germinated.
a. What is the question Sam is trying to answer?___Will a vitamin make radish seeds grow
better by making more sprout._______________
b. What is Sam’s hypothesis? Please use an if/then format.
__If I add a vitamin to the water used on radish seeds, then more radish seeds will sprout._
c. Identify 4 constant variables in the experiment.
1) Number of seeds
3) Amount of soil
2) Type of seeds
4) Sunny window
d. What is the independent variable in this experiment?_Vitamin or no vitamin in the water._
e. What is the dependent variable in this experiment? The number of seeds that sprouted.__
f. What are the results of this experiment?_With the vitamin = 1 out of 5 seeds sprouted___
__No vitamin = 4 out of 5 seeds sprouted.________________________________
g. What conclusion can you draw from this experiment? The vitamin does not help.
