  1. Lifeboats

  2. Question How many passengers will a lifeboat hold?

  3. Hypothesis 1. I think my 3cm boat will hold _______ passengers. 2. If my boat is taller, then _______ because ___________. 3. If my boat is shorter, then ______ because _______.

  4. Materials • Lifeboats • Notebook • Tub of water • Pennies

  5. Plan/Procedure • Gather material • Conduct investigation • Record results

  6. Results • My 3cm boat held an average of _______ passengers. • What happened when the boats were taller? (Skip 4 lines ) 3. What happened when the boats were shorter?

  7. Vocabulary • capacity: the greatest amount of fluid a container can hold • Variable: anything you can change in an experiment that might affect the outcome • Graduated cylinder: beaker, a tool used to measure liquid • Milliliters: unit of measurement • Syringe: an instrument used to inject fluids into something or draw them from it • Buoyancy: capacity to remain afloat or rise in air or gas

  8. Content/ Inquiry (skip 3 lines between each question) • What variables might affect the number of passengers your boat will hold? • Is there a relationship between the capacity of lifeboats and the number of passengers they hold? • What does not affect the number of pennies a paper boat will hold?

  9. Reflections • Name 3 things you learned while doing this investigation. • Name 2 things that surprised you during the investigation. • Name one question you have now that you have completed the investigation.
