Generate a data table to display your findings.

Display your findings as a bar graph for each variable (there will be 3 graphs).

A.    Analysis- Analyze your data, patterns or trends you observed using facts such from a chart or graph.

B.     Conclusion/Claim- Based on the facts or reasonable assumptions, the claim is a testable statement or conclusion that answers the original question.

1.     Evidence –Specific data that supports the claim based on a minimum of 3 pieces of evidence from your data; there is not any explaining here, only the facts as seen from the data. Select only the data that is both appropriate and sufficient to support the claim.

2.     Reasoning- This is the evidence to the claim. You want to explain how the evidence is connected to the claim using the science background knowledge and your science vocabulary and principles that allowed you to make that connection between claim and evidence.

C.     Discussion: Did your data support your hypothesis?  Were there possible variables that influenced results?

-      What would you do differently?

-      What are some new questions you have after doing this lab?
