Boat Basics
What shape is often used at the bottom of boats to help them float?
Flat Bottom or Hull
What must happen for an object to float?
It must be less dense than water
What happens if weight is not balanced on a boat?
It can tip or flip
What is an “engineer”?
A person who solves problems using science and design
What part of the boat keeps it stable in the water?
Keel or having a wide base
Will a heavy object always sink?
No, it depends on shape and water displacement
What’s the best place to put weight in a boat to keep it stable?
Low and centered
What’s the first step in the engineering process?
Ask or identify the problem
Why do we use Legos for this activity instead of metal?
Legos are lighter and easier to test with!
What gas helps many boats stay afloat?
Air trapped inside ( air bubble)
What unit do we use to measure how much weight a boat can hold?
Grams or kilograms
What does it mean to “test” your design?
Try it out and see how it works)
What do you call the front of a boat?
Bow
Which is the heaviest boat in the world
Supertanker Seawise Giant, also known as Happy Giant, Jahre Viking, Knock Nevis, aIts fully laden displacement was 657,019 tons.
What is one way to test how much weight your boat can hold?
Add small weights until it sinks
What’s a prototype?
A model of your idea used to test how it works)
What is the word for the back of the boat?
The Stern.
Which is the smallest boat in the world?
Guinness World Records, is a 11.5-micrometer-long (0.0004-inch) reproduction of "Benchy the Tugboat", a ship's model.
Your weight can change depending on where you are in the world, but your mass stays the same.
True or False
Weight is a measure of the force of gravity on an object's mass, and gravity varies depending on location. Therefore, your weight can change depending on where you are in the world (e.g., at the equator vs. the poles, or at sea level vs. high altitude), but your mass (the amount of matter in your body) remains constant.
who is the youngest engineer of all times?
Kairan Quazi, who joined SpaceX as a software engineer at the age of 14.
