From Lake to Potable- A H20 Online Installation

For the second H20 Action Project, GCE Freshman investigated the following guiding question:

How prepared are you in case of a water crisis? 

Here's the scenario students were challenged with: 
There was a flood in your city, and all water sources have been contaminated. To avoid relocating to a different city until the water treatment plant has been repaired, you decide to build your own water filtration system -- which will be used to filter drinking water until safe tap water is reinstated 2-3 weeks from now. Bottled water supplies are running low across the city, so time is of the essence. Using your knowledge of aquifers, pH and groundwater filtration, build a water filter that your family can use until the city is able to ensure tap water is safe to drink.
Please find below the online installation we created, featuring the water filters built by the students. Please click on the water filters to learn more about the process and whether the water was potable after filtering.

Alignment with Common Core Math & NextGen Standards

PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

ESS1-6. Apply scientific reasoning and evidence from ancient Earth materials, meteorites, and other planetary surfaces to construct an account of Earth’s formation and early history.

ESS3-4. Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

CCSS.HSN-RN.A.1. Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents.

CCSS.HSN-RN.A.2. Rewrite expressions involving radicals and rational exponents using the properties of exponents.

CCSS.HSN-Q.A.3. Choose a level of accuracy appropriate to limitations on measurement when reporting quantities.
