Scenario B:
A group of scientists have made three model aquifers by using three different types of permeable rocks. The permeable rocks they used were: gravel, sand, and potting soil. They polluted each model aquifer with food coloring and measured the spread of pollution in all three models.
A. Write a question that could be the basis of their investigation:
B. What is the hypothesis for this investigation?
C. Identify three factors that must be held constant during the experiment.
1.
2.
3.
D. construct a data table below that other students could use to record and analyze the data collected during the new experiment related to pollution diffusion in permeable rocks. Be sure to label rows and columns appropriately and to include units if necessary.
