### Pendulum Investigation

08.31.12

Lab Report FormatCopy for Warm-up

• Testable Question

• Background Information/Research

• Hypothesis

• Materials

• Variables and Controls

• Procedure

• Safety

• Results

• Conclusion

• How is the period of a pendulum effected by length?

• How is the period of a pendulum effected by mass?

• How is the period of a pendulum effected by release angle?

• Pendulum – body mounted so it swings freely with gravity

• Period – time for pendulum to complete 1 swing

• Simulation

• Fishing line

• Rubber stoppers

• Protractor

• Stopwatch

• Meterstick

• Balance

• Tape

• Basic laboratory safety

• No specific issues

• Write a detailed procedure for one testable question

• Identify the variables and controls for one testable question

• Create data table(s)

What factors should be considered when designing the pendulum investigation?

7th period warm-up

• What are the last two sections of a lab report?

• Complete investigation plan up to and including procedure.

• 10 minutes

• Work with person sitting next to you.

• Check with Mr. Founds if time permits

• Create graph displaying data

• Write conclusion in paragraph format. Include:

• Restate testable question

• Summarize procedure

• Summarize data

• Evaluate hypothesis

• Suggest improvements

• Suggest further investigations

• In paragraph format…

• What were you testing? (testable question)

• How did you complete your test? (procedure)

• What were the results? (graph)

• How could the investigation be improved?

Why is the pendulum lab considered a controlled scientific investigation?

• What are some challenges that your group has faced so far with the pendulum investigation?

7th period warm-up

• In the investigation you designed yesterday, what was your independent variable?

• For the pendulum lab, why is having ONLY ONE independent variable important?

• Choose what to test (length, mass, or angle)

• Select 3 different variables

• Complete 3 trials for each variable

• Keep all other factors the same

• Complete table

• Graph data

• Write conclusion

• On a piece of scrap paper…
