## Lesson Plan # 1 - Boat Construction - weight displacement

by

### Introduction

In this lesson students will construct a boat and calcluate the water line in advance of putting it in the water. Students will learn basic boat terms.

The standard definition of floating was first recorded by Archimedes and goes something like this: An object in a fluid experiences an upward force equal to the weight of the fluid displaced by the object. So if a boat weighs 1,000 pounds (or kilograms), it will sink into the water until it has displaced 1,000 pounds (or kilograms) of water. Provided that the boat displaces 1,000 pounds of water before the whole thing is submerged, the boat floats.
