1. Physics Thursday 11-8 Finish Lab Info gathering
Work on calculations, write-up
Any old homework
See Play

2. Finish Gathering information
With the rubber-band
With the wood and paint stirrer

3. Finish Calculations
Will want the calculations done in a neat sequential manner on a separate piece of paper
All group members have the same calculations for the wood launch and the farthest rubber-band launch
Each individual will have additional calculations on a 2nd rubber-band launch different from the rest of the group

4. Descriptions
In addition to the calculations, write a concise description of the set-up for the most successful rubber-band shot.
Write a paragraph indicating the most significant sources of error affecting the calculations. Be specific in your description.
Don’t say “ measuring”, but indicate how error might have been introduced for specific measurements

5. Percent Error for angle
Wood-Paint stirrer part
Indicate the % error difference between the calculated angle of launch and the initial angle of the paint stirrer
│calculated angle – paint stirrer angle │
X 100
Paint stirrer angle

6. Mass values
Measure the mass values of your marshmallow shot and the paper shot
Visit each group and record their paper shot mass value and their farthest range value.
Write a brief statement indicating if you believe there is any relationship between the mass of the shot and the range it travels. Explain your position.

7. What is due for the lab 1) The paper with all the information
2) Calculations for the wood/stirrer projectile
3) 2 sets of calculations for the rubber-band projectile
Max range projectile
2nd individual projectile
Description of how the group shot the rubber-band
Detailed paragraph on sources of error
Percent error calculation for wood/stirrer projectile

8. Any old homework?
No homework today through weekend

9. Books
Those who have books, please bring them back to the classroom by Monday
