Aim:
I want to find out how to make a boat float.
Research:
Method:
Equipment:
- 30cm square tin foil
- Tray of water
- Corks for weight
Instructions:
- Get your equipment ready.
- Fold your tin foil into a boat using the instructions from the video
- Float the boat in the water.
- Add corks onto boat until it sinks.
Results:
Danny (the boat, not a person) was able to hold 40 corks before he sunk.
Discussion:
How/why do boats float?:
The weight of the water that the object is displaces determines the nett upward force acting on the object.
What is density?:
The degree of compactness of a substance.
Archimedes Principal:
The Greek mathematician and inventor Archimedes discovered the physical law of buoyancy, which states that any body completely or partially submerged in a fluid (gas or liquid) at rest is subject to an upward, or buoyant, force whose magnitude is equal to the weight of the fluid displaced by the body. The volume of fluid that has been displaced is equal to the volume of an object that is completely submerged in the liquid or to the portion of the volume below the surface for an object that is only partially submerged. The buoyant force’s strength is equal to the weight of the fluid that has been dispersed.
I hope you enjoyed this experiment, bye!
