1. Monday 9/25/17
Copy this week’s schedule into your assignment notebook.
Notebook Entry: Look back at your Science of Boat Design notes. Find the section about density and review what it means. Explain how density causes the cork to float, but the rock to sink.

2. Displacement

3. Build a Better Boat – Reflect and What’s the Point
Answer the 3 reflect questions – pg DIG 22 in sheet protector or found on my webpage.

4. Build a Better Boat 2
Just when you thought you had it all figured out, the gatekeeper tells you that you that your boat must float through the 5 cm opening and carry two more keys (one hex nut).
He wants you to show him a final design that will carry 8 keys (4 hex nuts) and fit through the 5 cm opening. He will then be confident in giving you the keys to the fort.

5. Criteria and Constraints
Build a Boat
Must fit through a 5cm wide opening.
Float for 20 seconds
Carry 8 keys (4 hex nuts)
Build and Test in 10 minutes
5” x 5” piece of tinfoil
No other materials
One get 1 piece of tinfoil

6. Build a Better Boat 2
As you plan your design think about what you have learned about density and buoyancy.
You are welcome to use ideas of other groups, but you must make sure to give them credit.
Keep track of your design(include measurements and labels) and number of keys the boat holds on your Boat Records Sheet.
