Bellwork We have talked about groundwater and some of the ways it can become contaminated. So...what could be in our drinking water? Explore this website to find out! https://www.ewg.org/tapwater/

Objective Explore the relationship between porosity and permeability empirically.

Porosity vs. Permeability Porosity = amount of water that can be stored in the pore spaces (air pockets) Permeability = ability of water to flow through connected pore spaces 3

How does soil particle size affect porosity and permeability? Question How does soil particle size affect porosity and permeability? How can we make this question into a statement of purpose for our lab?

2. Research/Prior Knowledge What do we already know about: Soil particles? Porosity? Permeability?

(If...then statement that makes a prediction about the question) 3. Hypothesis (If...then statement that makes a prediction about the question)

4. Experiment How can we test PERMEABILITY of different soil particles? Independent Variable: Dependent Variable: Materials: Procedure:

What do the graphs suggest? 5. Analysis What happened? What do the graphs suggest?

Did the data support my hypothesis? 6. Conclusion Did the data support my hypothesis?
