  1. Investigation 2: Lifeboats

  2. Introduction • Today, you are going to investigate lifeboats! • What are lifeboats and what are they used for? • Lifeboats carry passengers safely away from distressed ships.

  3. Passengers: How many passengers can your lifeboat hold BEFORE it sinks?

  4. Explore: Test your boats several times to see how many passengers it takes to sink your lifeboat

  5. Variables of the lifeboat • Reporters report out how many passengers your boat HELD? • What is a variable? • What variables affected the number of passengers your boat could hold?

  6. Capacity • How could we check the variable of our boat size? ( to find out if in fact all the boats are identical) • I suggest we measure our boat’s capacity! Watch me demonstrate this!

  7. Four New Boats • We will investigate the variable of boat size to see how it affects the number of passengers a boat can hold. • You will construct four new boats, each different sizes! • All boats should be no shorter than 2 cm and no taller than 4 cm from base to top.

  8. Capacity • After you make the boats, measure their capacity. • Name each boat and write the name AND capacity on the side with permanent ink.

  9. Wrapping Up Part 1 Vocabulary Content/ Inquiry What variables might affect the number of passengers ( pennies) a paper-cup boat ? Variables might affect the number of passengers are: placement, water movement, and boat size • Capacity is

  10. Part 2: Lifeboat Inspection

  11. Lifeboat Inspection • REVIEW: What is the meaning of a controlledexperiment? • Today, we will conduct a controlled experiment to find out how the variable of capacity affects the number of passengers a lifeboat can hold.

  12. Standard Boat-Loading • We need to decide as a class what our standard for boat loading will be. • How should we place the pennies in the boat? • How should we handle the basin? • What are your thoughts about the pennies? Wet or dry?
