15. ANS: C PTS: 1

SHORT ANSWER

16. ANS:
If the landfill is close to the city, residents of the city would not want to live near it, would see the value of their property decline, and would most likely organize protests against having the landfill close by. If the landfill is far from the city, trucks would have to drive the garbage long distances to dispose of it. This would lead to high costs to taxpayers for gas, oil, and road and truck maintenance, and would also contribute to air pollution.

PTS: 1 DIF: 3 REF: 1 OBJ: 3

17. ANS:
Some waste simply does not burn; incinerators give off a certain amount of toxic particles and gases, even with pollution control devices; and the ash that remains after the waste is burned must still be disposed of.

PTS: 1 DIF: 3 REF: 1 OBJ: 2

18. ANS:
The first way is to produce less waste, such as choosing products with as little packaging as possible. The second way is to recycle, which saves resources and energy. The third way is to change the materials we use, as in developing truly biodegradable “plastics.”

Adding Methods and Materials to your renewable energy project




Today, you will add methods and materials to your renewable energy project. 

1. Find a renewable energy experiment you feel you can complete as a group. 

You may want to start with the textbook:

Resources: http://my.hrw.com/
      Login: eav6e1





   password: j8y4j  

Then you can google search for projects. Just make sure it's not to complex to complete in a couple of days. 

2. Add a slide with the materials for your experiment.

3. Add a slide with the methods (procedures).

Email the slideshow to me: tmegahan@dallasisd.org

3. Add a slide with the methods for your experiment.

Renewable energy project from  Wednesday/Thursday

Slide one: Title Slide. All group member names
need to be here.

Slide two:  Purpose Statement

Slides three and four:

Supporting Details. Should include:
  1. Information about why nonrenewable resources are impractical, based on your calculations, graphs from yesterday's activities, and any of the graphs from Chapter 17. Include the graph
  2. Information about which renewable energy resource will be most important in 2050. Graphs must be included. This information can be found on Chapter 18.  
Slide five: Hypothesis

Modeling a Sanitary Landfill



Today, you will build a model of a sanitary landfill. Use page 485 as your guide. There are projects from last year to use as well.



Before you can build you need to write:

Introduction -- a good intro includes:
  • A purpose statement (Look to the LO)
  • Three supporting details (Remember to cite your text...According to...)
  • A hypothesis that logically follows the details (look at the rubric for how to write this) 
 While you are building you need to write:

A materials list (look at the model)
A procedure (make sure your layers are right!)


A couple of important things to consider:


  • you need to use a probe and the burner in the back of the room (vent hood) to make holes in your bottle lid. 
  • you need to 10 mL of water in the bottom for groundwater.
  • you need to put 5 drops of dye on top to prove that you don't have any leachate leakage.
