  1. What makes water such a good solvent? Why water is is a good solvent.

    • Water is called universal solvent because more substances dissolve than in any other chemical. This has to do with the polarity of each water molecule

2. What are triple covalent bonds?

    • True

15. What is a concentrated solution?

    •  A solution where a solute is more present.


16. Describe Ionic Bonding and Covalent Bonding?


    • Ionic Bonding is the loss/gain of electrons between atoms. Covalent bonding is the sharing of electrons between atoms.

17. What is the difference between endothermic and exothermic?

    • Endothermic reaction cold when touched. Exothermic reaction hot when touched.

18. What is Balancing Equations?

    •  Matter that cannot be created or destroyed.

19. What is different between heat and temperature?

    • Heat is the flow of thermal energy from one place to another. Temperature is the amount of is the measure of how fast the molecules of the substance on average is moving.

20.  Study the lab handout provided by your teacher.  Define all Italicized words.  Be sure you understand how factors affecting crystal growth.  Explain the type of bonding in sodium borate and the formation of its crystals.

Ecological Footprint Activity
Due Date: 9/9/2013
Subject: Chemistry



Ecological Footprint Activity



1.  Go to this website:  http://www.footprintnetwork.org/en/index.php/GFN/

2.  Under Footprint Basics, read Introduction and Overview.  Then define ecological footprint in your own words.  What does it actually measure?


3.  Under Footprint Basics, go to Personal Footprint and take the ecological footprint quiz for yourself.  Enter as a new user, create your avatar and always enter the more detailed information.


4.  Record your ecological footprint.

a.       How many planet Earth’s would be required if everyone lived like you?  _______

b.      Break down your ecological footprint:

         ____% Food   ____% Shelter   ____% Mobility   ____% Goods   ____% Services

c.       How many global acres of the Earth’s productive area do you require? _______

d.      Put the following in order from most land used to least land used: energy land, crop land, grazing land, forest land, built up land, fishing grounds


e.      How many tons of carbon dioxide do you generate?  ________   The Earth can absorb some of our carbon dioxide (do you know how?), but not at the rate we are producing it now.  So, the fewer tons you personally produce, the better.  We will study this more later.

5.  Click on “edit your footprint.” Only make changes that you can actually make in your life. For example, do not change your house since your parents/guardians would not approve it. Instead, change your recycling habits or food intake.   

          a.   How low can you get your footprint to be?  Record it here:  _________     

          b.   List five things that you can do to make your footprint lower. 


6.  Click on “explore scenarios.”  Click on the checkboxes one at a time.

          a.   How do the listed activities affect your ecological footprint in terms of the number of planet Earth’s needed?


          b. If every American did only one of these activities, which would be the most effective in reducing our           ecological footprint?



          c.   Could you commit to doing one or more of these activities? If so, which one(s)? If not, why?



Reflection Questions:

1.       We will gather data from everyone in the class concerning their footprint in global acres. 

a.       What is the total footprint of the class?


b.      What is the average footprint of the class?



c.       How does this compare to the average American’s footprint (23.7 global acres/person)?


d.      Biocapacity is the capacity of an area to provide resources and absorb wastes.  The total biocapacity of the Earth is estimated to be 4.4 global acres/person.  Is our class running an ecological deficit or an ecological surplus?


2.       Think about the fairness of world land use.  The U.S. has an ecological footprint of 23.7 acres per person while the 35 low-income countries average 2.0 acres per person.

a.       Why do you think the average ecological footprint is so much higher in the U.S. than developing countries?



b.      Do you think there should be laws governing how large a country’s or individual’s ecological footprint?  Explain. 



3.       Sustainability is an important concept in Environmental Science.  It means that resources are not being used up faster than they can be replenished, and that wastes are not being produced faster than they can be processed by the earth. 

a.       Are Americans living a sustainable lifestyle? 



b.      Are YOU living a sustainable lifestyle?


c.         How will this affect future Americans?  How will this affect the world? Explain. 



4. According to the Footprint Network, “Earth Overshoot Day marks an unfortunate milestone: the day in which we exhaust our ecological budget for the year. Once we pass this day [each year], humanity will have demanded all the ecological services – from filtering CO2 to producing the raw materials for food – that nature can provide this year. From that point until the end of the year, we meet our ecological demand by liquidating resource stocks and accumulating carbon dioxide in the atmosphere.”  The Earth first experienced overshoot on December 19, 1987.  In 2007, overshoot day occurred on October 6, 2007.    

Use the following formula to calculate overshoot day:


            [ world biocapacity / ecological footprint ] x 365 = Ecological Debt Day


(If the Ecological Debt Day is calculated to be Day 10, then that is January 10th.  For October 6, 2007, the 279th day of the year, the Ecological Debt Day was Day 279.)


a.  When is overshoot day for the world? (world biocapacity=4.4 global acres/person; ecological footprint =5.5)



b.  When is overshoot day for the U.S.? (U.S. biocapacity= 11.7 global acres/person; US ecological

footprint =23.7)




c.                   When is overshoot day for our class? (U.S. biocapacity=11.7 global acres/person; class ecological footprint=answer to reflection question 1b)



d. How does overshooting our ecological resources negatively affect the planet in the present day? How do you think it will affect our planet in future generations?
