Identifying Variables Worksheet

For the following experiments, define the IV (independent variable), DV (dependent

variable), and CG (control group).

1. Different rose bushes are grown in a greenhouse for two months. The number of

flowers on each bush is counted at the end of the experiment.

2. You water three sunflower plants with salt water. Each plant receives a different

concentration of salt solutions. A fourth plant receives pure water. After a two-

week period, the height is measured.

3. Three redwood trees are kept at different humidity levels inside a greenhouse for

12 weeks. One tree is left outside in normal conditions. The heights of the trees

are measured once a week.

4. Pea plant clones are giving different amounts of water for three-week period. The

first pea plant receives 400 milliliters a day. The second pea plant receives 200

milliliters a day. The third pea plant receives 100 milliliters a day. The fourth pea

plant does not receive any extra water: the plant only receives natural ways of

receiving water. The heights of the pea plants are recorded daily.
