<!-- 1. Draw a schematic of a wind powered (sail) boat showing pertinent features and how they function. Features should include, but not be limited to a boom, hull, jib, keel, mainsail, mast, and rudder. How do features commonly removed from toy boats affect functionality? -->

There are many websites that show the parts of a sailboat. Instructors should discuss that in toy boats, missing parts do affect movement such as: a missing keel may keep the boat from going straight; and a missing rudder would not allow the boat to be turned. One reference website is [https://adventure.howstuffworks.com/outdoor-activities/water-sports/sailboat1.htm How Stuff Works - Sailboat]

<!-- 2. Draw a plan for a rubber band-powered toy boat of a design of your choosing showing pertinent features that differ from a wind powered boat. -->

These boats typically have a water paddle that is in some way connected to the hull with a rubber band. The paddle is wound that in turn winds the rubber band and motion is initiated with the paddle/rubber band is released. YouTube, Pinterest, and general searches on an internet web search will provide many videos and step-by-step instructions showing a multitude of designs.

<!-- 3. Be able to describe Archimedes’ Principle of Buoyancy and how this principle applies to all boats. -->

An upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. A boat will float if the weight of the boat and all of its cargo is less than the weight of water that it displaces (62.4 lbs/cf or 998 kg/m3)

Water expands over a thousand times when it becomes steam. One may place a zip-lock baggie in a microwave with a teaspoon of water and see the vapor expand the baggie.

You can find more information on Wikipedia about [[w:Archimedes%27_principle|Archimedes’ Principle]].

<!-- 4. Be able to describe Newton’s First Law of Motion and how this principle applies to all boats. -->

According to [[w:Newton%27s_laws_of_motion|Newton's first law of motion]], an object (boat) at rest will remain at rest unless acted on by an unbalanced force (wind, rubber bands, pushing, waves, paddles, etc.). An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force (opposing wind, friction of water, shore line, etc.).

<!-- 5. Be able to describe Newton’s Third Law of Motion and how this principle applies to a wind-powered (sail) boat. -->

According to [[w:Newton%27s_laws_of_motion|Newton's third law of motion]], <u>every action has an equal and opposite reaction</u>. The wind imposes a force on a sail and the boat will move when the force can overcome the resistance from the boat in the water. The larger the area of the sail, the more wind "force" is collected to overcome the boat resistance. The lighter the boat, the less force needed to overcome resistance.

<!-- 6. Be able to describe the difference between Potential Energy and Kinetic Energy. Discuss how and when a toy rubber band powered boat uses both types of energy. -->

The rubber band contains the energy. When the rubber band is wound up, the energy is stored energy = [[w:Potential_energy|potential energy]]. When the rubber band unwinds it is releasing energy by moving = [[w:Kinetic_energy|kinetic energy]].

<!-- 7. Use recycled materials to make at least one toy wind powered (sail) boat and at least one toy rubber band powered boat. Each toy boat will be no wider than 4 inches (10 cm) and suitable for travel in a 6-inch (15 cm) wide lane of water. -->

YouTube, Pinterest, and general searches on an internet web search will provide many videos and step-by-step instructions showing a multitude of designs.

<!-- 8. Participate in an organized wind-powered (sail) boat race using a boat you have made to complete this honor. -->

Two or more "tracks" may be made with 6-inch house aluminum guttering, sealing the ends, and filling with water. At the start, participants are to use same size straws to blow on sails and the first boat to the end is the winner. Winners from each heat are then paired together until a final winner is determined for the group.

<!-- 9. Participate in an organized rubber band boat race using a boat you have made to complete this honor. -->

Two or more "tracks" may be made with 6-inch house aluminum guttering, sealing the ends, and filling with water (may be the same tracks as used for the wind boat race).  The participants are to place a wound-up boat in the water and released at the start of the race. The first boat to the end is the winner. Winners from each heat are then paired together until a final winner is determined for the group.
