Can we analyze and evaluate the impact of man’s use of earth’s land, water, and atmospheric resources?
SPI 0707.7.7 Analyze and evaluate the impact of man’s use of earth’s land, water, and atmospheric resources.
Which natural material do you think works best to reduce runoff? Why do you think so?
Imagine First we examined roof surfaces and their effect on runoff. What is it useful to add green roofs to buildings? In cities, why is it useful to have paved areas? How do paved areas add to the runoff problem? Today we are going to investigate permeable pavements. Reflect back to the introduction video. There was a technology called porous or permeable pavement. How did this technology work? What does the word permeable mean?
$$$ Check Green Roof Data Chart= $500 Today you will have a cost restraint of $200. You may not spend any of your green roof money; however, I will give you a $200 allowance to test permeable pavement. There is a catch, your pavement must meet two criteria: 1. The pavement must absorb water. 2. The pavement must be smooth enough for people to use for walking and driving.
$$$ Money Permeable Pavement Data Chart= $500 Glue the Materials Price List into your STEM notebook. Create the chart to the right in your STEM notebook:
Imagine: Action Research List your control (variables) factors and the independent and dependent variables. Place the small foil tray into the large foil tray to catch extra water…watch me! Test the pavements in the small foil tray. Test the usability of the pavement by seeing whether a wind-up toy can walk on their pavement in a straight line. Spray the pavement with 20 squirts of water. Wait 20 seconds. Record how well the water soaks in. Be prepared to share your data with the whole class after testing.
How can we, as environmental engineers, use what we learned in our investigation to keep polluted runoff out of the river?
