Problem: Understand how different levels of acidity affect the mass of shells

Background knowledge:

Hypothesis:  If_______ then _______ because

Materials:

Procedure:

 Type up your lab.  SEE ATTACHED for your evaluation rubric and guide to writing a lab.

1)            Title and names

2)            Statement of the Problem

3)            Background Information:

a)   What is the historical pH level in the ocean?

b)   How much is the pH changing?

c)    What organisms does the changing pH affect?

d)   What is causing the change in pH levels?

e)    What common household ingredients could be mixed with water to change pH in water?

4)            Hypothesis: If __________ then ______________ because

5)            Materials (as a list)

6)            Procedure

7)            Results:

a)   Analyze your results and explain it to the world - be scientific explaining what you proved with your experiment

b)   Ex.  The shell that was in lemon juice for 13 days with a pH of 5 experienced a change in weight of 12%.  It was also observed that the colour changed, 5 2mm holes were formed and the shell became very brittle breaking easily with slight hand pressure.

8)            Conclusion: 

a)           Answer your intital question

b)           Explain whether your hypothesis was correct

c)           Explain any potential mistakes in this experiment (like evaporation)

d)           How can this information be applied to the real world problem of the rise in ocean acidification?

e)           What further research could be done in our lab and out on the oceans to learn more about this problem?
