1 TASK 3 : CREATE A NEW CITY MAP Be Creative Follow Your Laws Think about Zoning Think about sustainability

2 Where will rainwater go ? Civil Engineers need to design a system to handle storm water

3 TASK 4 DESIGN A MODEL HOME / YARD What are some choices for building materials?

4 WOOD: “Stick built” home

5 Insulating a stick built wall. Notice the studs are not insulated

6 ICF Insulated Concrete Form

7 Concrete is poured in the ICF making an R-50 wall ! Great insulation!

8 ICF form. Build a house with your bare hands

9 Straw Bale Construction. R 35- R50 walls.

10 Straw House from the inside

11 Finished Straw House with solar collectors

12 Could a home be built with tires?

13 Earthship home. Built of tires and cans.

14 Earthship Home. Designed to interact with the environment

15 Earthship home : Built to collect solar energy

16 Building an off-grid home into the earth. Advantages?

17 Earthship homes are “off-grid” note photovoltaic cells

18 Inside an earthship home

19 Earthship bottle wall

20 Can a home be a farm? All earthship homes are designed to produce food

21 Ground Source Heat Pump

22 Yard dug up to put ground source heat pump coils in.

23 GROUND SOURCE HEATING AND COOLING.. Also called geothermal

24 Septic System : sewage is broken down by bacteria in tank and soil

25 Septic Tank and drain-field. Bacteria in soild break down sewage. Plants absorb nutrients

26 Drain field pipes will be buried.

27

28 Keep drain field away from your well!

29 Task 5: write a PUBLIC SERVICE ANNOUNCEMENT about Biomagnification Write A public service announcement about biomagnification of mercury from the old coal burning power plant. This announcement must include the words: MERCURY. BIOMAGNIFY. FOOD CHAIN. ____ Educate citizens on the process of biomagnification ____ Explain why larger fish are more dangerous to eat than smaller fish even if you eat the same amount ______ Explain the effects of mercury poisoning ____ Explain how mercury entered the foodchain of dragonfly lake ____ Suggest limits on eating Walleye under 21 inches from Dragonfly Lake. … and limits on eating walleye over 21 inches from dragonfly lake. We will use the data on the MN DNR website for…… Lake and pretend that is the data for dragonfly Lake Write the announcement so that it can be read aloud in a 1 minute advertising slot at the new town radio station

30 Website to learn about bioaccumulation of mercury

31 Mercury is a silver liquid

32 Mercury poisoning affects development. Strongly affects the nervous system

33 Mercury doesn’t ever go away… moves through food chains

34 Mercury magnifies through food chains = biomagnification

35 Minamata Japan. Site of huge mercury release in mid 20 th century

36 Minamata disease. Severe mercury poisoning from eating seafood
