➢ Specific values listed for controlled variables (-1 each part)
➢ Record data as step (-1)
• Data
➢ Data tables
• Title (-1)
• Labels – physical quantity and units (-1)
• Significant digits (acceleration should not have more than recorded distances or times –1)
➢ Sample calculations- formula (-1) numbers plugged in (-1)
➢ Graphs
• Titles (-1)
• On graph paper or printed grid if computer (-1)
• Straight edge for axes (-1)
• Labels – physical quantity and units (-1)
• Best fit line- straight or smooth curve not dot to dot (-1 each time )

• Straight lines continued to intercept (-1)
• Both axes start at zero (-1 each time)
• Interpretation
➢ Graph interpretations (for each graph)
• General statement of what graph shows eg. “the straight line on the acceleration force graph shows acceleration is proportional to force” (-1 each time)

• Conclusion
➢ Did data support hypothesis with hypothesis restated in some form (-1 each time)
➢ Specific data supporting above statement (-1 each time)
