What happened to the pollutants on the model city when we created a rainstorm last time? What does the foil on the city model represent? If we were to replace paved surfaces with a different material, what material would you choose and why?

Don’t Runoff Challenge Engineers are people who design and improve technologies in order to solve problems or meet needs in their communities, such as preventing pollution from contaminating local waterways. Challenge: How can we keep polluted runoff out of a clean river? Pollutants can travel directly into bodies of water where they become concentrated and more dangerous. Your challenge is to design a model city to help prevent runoff. Your design will enable cities like Nashville to prevent water pollution while creating a more “green” city.

Can we analyze and evaluate the impact of man’s use of earth’s land, water, and atmospheric resources?

SPI Analyze and evaluate the impact of man’s use of earth’s land, water, and atmospheric resources.

Engineering Green Roofs Part I: Engineer a model building at least 23 centimeters (9 inches) high Materials for building structure: 40 index cards, 30 cm (1 ft.) of foil, and a roll of tape 1 cup of water will be added to your rooftop (none may run off); your building must support the weight of the saturated green roof. Part II: Engineer a roof for the building that reduces runoff by absorbing water Materials for roof: soil, gravel, moss, and sand

Imagine: Research Green Roofs by Experimenting Make a plan with your team to test the different types of green roofs. What will be your control factors and variables (independent and dependent)? How will your control group be different from your experimental groups? Record these in your STEM notebook You can earn up to $500 for detailed and accurate data.

Bell Work: 9/15/14 Read the blog “Nashville Music City Center Green Roof”. Why was a “green roof” installed on top of the new Music City Center in Nashville? What will happen to storm water as a result of the green roof? How does the green roof work? How will some of the rain water be reused?
