Copy the blank graph below onto your Catalyst sheet, and label the following parts: - X axis- Y axis- Axis where “Mass of Liquid” should be- Axis where “Calculated Density of Liquid” should be- Axis where “grams” should be - Axis where “grams/milliliters” should be- Title (and what should the title be?)

Catalyst

Homework

• Create final copy of Observations (either typed of written as a final copy on a separate sheet of paper)

• Create final copy of Graph (created on a separate sheet of graph paper)

1. What was your hypothesis for the Calculated Density lab? Write it down on your Catalyst sheet.

2. Look at your graph. What relationship between the IV and DV do you think is represented on your graph? A positive, negative, or no relationship? How do you know this?

3. Based on the data in your data table and your graph, was your hypothesis supported or rejected? Explain.

Catalyst

What relationship exists between the variables?

• Positive relationship

• Negative relationship

• No relationship

Conclusion

• What is the purpose of your Conclusion?

Conclusion must haves!

• Restates the question in the form of a statement.

• Restates the hypothesis.• Tells whether the hypothesis was supported or

rejected.• Uses data from the data table and/or graph as

evidence for support.• Ends with a summary statement.• Is written in paragraph form.

Homework

• Write a rough draft of your Conclusion in your science notebook

• Use the rubric as a guide!

Conclusion• Pencil

Below are the “accepted” densities for the liquids you tested in class. Copy these down onto your Catalyst sheet, and then answer the following questions:

Corn Syrup – 1.38 g/mLSalt Water – 1.05 g/mLLiquid Water – 1.00 g/mLRubbing Alcohol – 0.79 g/mL

1. What do you think is meant by the term “accepted density”?2. How do your densities compare to these accepted densities?

Catalyst

Conclusion

• You should have a rough draft of your Conclusion written in your science notebook

• Your next homework assignment will be to create a final copy of this Conclusion

Inference

• What is the purpose of the Inference of a lab report?

Inference must haves

• I would suggest starting the Inference with your problem statement again, just like the Conclusion

• Explain results using key terms (mass, volume, density, accepted density?)

• Propose a possible source of error• Suggest a way to eliminate the source of error

Homework

• No homework due to concert
