Float or sink
Weight & Balance
Engineering Terms
100

What shape is often used at the bottom of boats to help them float?

Flat Bottom or Hull

100

What must happen for an object to float?

It must be less dense than water 

100

What happens if weight is not balanced on a boat?

It can tip or flip

100

What is an “engineer”?

A person who solves problems using science and design

200

What part of the boat keeps it stable in the water?

Keel or having a wide base 

200

Will a heavy object always sink?

No, it depends on shape and water displacement

200

What’s the best place to put weight in a boat to keep it stable?

Low and centered

200

What’s the first step in the engineering process?

Ask or identify the problem

300

Why do we use Legos for this activity instead of metal?

Legos are lighter and easier to test with! 

300

What gas helps many boats stay afloat?

Air trapped inside ( air bubble)

300

What unit do we use to measure how much weight a boat can hold?

Grams or kilograms

300

What does it mean to “test” your design?

Try it out and see how it works)

400

What do you call the front of a boat?

Bow 

400

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.

400

What is one way to test how much weight your boat can hold?

Add small weights until it sinks

400

What’s a prototype?

A model of your idea used to test how it works)

500

What is the word for the back of the boat?

The Stern. 

500

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. 

500

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.

500

who is the youngest engineer of all times?

Kairan Quazi, who joined SpaceX as a software engineer at the age of 14.
