Genetic disorder poster project

Genetic Disorders Poster Project

• From the list included in the Genetic Disorders Folder Choose a disorder.
• Print your name next to the disorder you are making a poster for.
• Research your disorder.
• Include on your poster
• Name of disorder
• Description of disorder
• Cause of the disorder
• Phenotypic expression of the disorder (pictures are appropriate here)
• Treatment or cure
• Prevention (either within ones life or by ones parents)

• Bibliography(please use at least three separate sources)

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?
