carbon footprint

Calculate your carbon footprint

Calculator



Upon calculating your footprint choose 1 area that you assessed and develop a plan to reduce your carbon emissions.

Calculate the following

1. How much would you reduce your footprint by making this change?
2. How much would this change cost you as a consumer.

Period 1 Postlab Assignment

1. Within your group produce a graph that shows the relationship between playing video games and reaction time. (every student must have a completed graph)

2. Compare your groups graph to the class data

 3. Write a brief discussion ( steps 1 and 2 ) that answers the question. "Does playing video games improve reaction time?"

Quiz Friday

Quiz on water and pH friday

Osmosis lab

Create an experiment to test how water moves through a membrane in response to a concentration gradient

Materials:
Dialysis tubing
10% salt solution
Distilled water
Plastic cups
Scale

Incubations
10% salt
8% salt
6% salt
4% salt
2% salt
0% salt (distilled water)

Data Table

% salt
Mass of Bag (initial)
Mass of Bag (Final)
%Change in mass
 10%



 8%



 6%



 4%



 2%



 0%





% change in mass=[ Mass of bag (final)-Mass of Bag (initial)]/Mass of bag (initial) * 100


After setting up your experiment:
1. Write a prediction about what you believe is going to occur to the mass of each bag.  Explain why you believe this will occur. Include in your statement what materials are moving through the membrane, what materials are not moving through the membrane and explain why.
2. Create a graph illustrating your predictions

After collecting your data
1. Report your data
2.Create a graph using the class data
3. Using your predictive statement from above and the data collected from the experiment write a paragraph which includes the following information:
A. Is your prediction correct?
B. What data supports your statement? (use specific numbers here)
C. Explain why this happened (what scientific principle is at work here)
D. Why is this important in biology? Give a real world example where this would be important
E. What mistakes were made in the lab? How did these mistakes influence the data? How would you correct these mistakes in the future?
