Worksheet Directions: For the following experiments identify the three variables for each experiment, the Independent Variable, the Dependent Variable and the Control Variable. 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. a. Independent Variable b. Dependent Variable the number c. Control Variable de different rose bushes are grown of flowers are counted. greenhouse for two month 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. a. Independent Variable b. Dependent Variable c. Control Variable 3) Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. One tree is left outside in normal conditions. Height of the tree is measured once a week. a. Independent Variable b. Dependent Variable c. Control Variable 4) Pea plant clones are giving different amounts of water for a three-week period. 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 height of pea plants is recorded daily. a. Independent Variable b. Dependent Variable c. Control Variable

Dissection

Dissection is the process of cutting up the tissue of a dead or live animal or plant, to do anatomical studies and surgical treatments. The purpose of dissection is to learn more about the overall structure of organs and organ systems and thereby understand the physiology of the organism.
