A hypothesis is a possible explanation for observations, or an educated guess about what you think will happen in your experiment. Fertilizer adds those nutrients to the soil, thus allowing plants to grow more. Well, your data “supported” your hypothesis, but your experiment did not cover that much ground. Developing a Testable Hypothesis For each of the following scenarios, develop a testable hypothesis as well as identify the investigative question, cause, effect, independent variable, and dependent variable. If I increase the current supplied to an electric motor, then the RPMs (revolutions per minute) of the motor will increase. When you go and dig a 3-foot by 3-foot-wide and 1-foot-deep hole in the dirt in those two states, you discover Floridian earthworms, but not Alaskan ones. Ag Science: HYPOTHESIS WORKSHEET ANSWERS.
