You are interested starting a roadside produce business and wish to improve the quality of your peanut plants. Nitrogen is an essential macronutrient for protein synthesis and photosynthesis in plants. However, it is often considered to be a limiting nutrient - available in short supply in nature. In agriculture, a common way to increase plant yield is to apply fertilizers that contain essential nutrients. You design an experiment that compares the height (growth) of two groups of plants after exposure to fertilizer.
Group A has 50 peanut plants that receive fertilizer.
Group B has 50 peanut plants that do not receive fertilizer.
After two weeks you measure the changes in height and observe that plants from
Group A had an average height of 12.43 cm and plants from
Group B had an average height of 12.38 cm.
a. From this experiment, identify the following on the end of lab worksheet: the control group, experimental group, independent variable, and dependent variable.
