testable questions
Testable Questions
  • 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?
background information
Background Information
  • Pendulum – body mounted so it swings freely with gravity
  • Period – time for pendulum to complete 1 swing
  • Simulation
materials
Materials
  • Fishing line
  • Rubber stoppers
  • Protractor
  • Stopwatch
  • Meterstick
  • Balance
  • Tape
safety
Safety
  • Basic laboratory safety
  • No specific issues
in lab groups
In lab groups…
  • Write a detailed procedure for one testable question
  • Identify the variables and controls for one testable question
  • Create data table(s)
warm up
Warm-up

What factors should be considered when designing the pendulum investigation?

7 th period warm up
7th period warm-up
  • What are the last two sections of a lab report?
seventh period
Seventh period
  • Complete investigation plan up to and including procedure.
  • 10 minutes
  • Work with person sitting next to you.
  • Check with Mr. Founds if time permits
after collecting data
After collecting data…
  • Create graph displaying data
  • Write conclusion in paragraph format. Include:
    • Restate testable question
    • Summarize procedure
    • Summarize data
    • Evaluate hypothesis
    • Suggest improvements
    • Suggest further investigations
conclusion
Conclusion
  • 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?
warm up1
Warm-up

Why is the pendulum lab considered a controlled scientific investigation?

science warm up
Science Warm-up
  • What are some challenges that your group has faced so far with the pendulum investigation?
7 th period warm up1
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?
procedure
Procedure
  • 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
before you begin
Before you begin
  • On a piece of scrap paper…
    • What is your IV?
    • What is your DV?
    • Why are we doing multiple trials?
    • What do you do after collecting data?
