Worksheet time: 7mins
What was King Hiero's main concern about his new crown?
It was too heavy.
It was not shiny enough.
It might not be made of pure gold.
It didn't fit his head.
What did the King think the goldsmith might have done to the gold?
Used less gold than he was given.
Mixed the gold with a cheaper metal.
Stolen the crown.
Made the crown too small.
Who did King Hiero ask to help him figure out if his crown was pure gold?
Another goldsmith
Archimedes
His royal advisor
A merchant
What scientific idea did Archimedes use to solve the problem of the crown?
Gravity
Density
Magnetism
Temperature
What does density measure?
How much space an object takes up.
How much light an object reflects.
How much a material weighs when it fills a certain amount of space.
How hot or cold an object is.
How does the density of gold compare to the density of silver?
Gold is less dense than silver.
Gold is denser than silver.
Gold and silver have the same density.
Density cannot be measured for gold or silver.
What is the approximate density of pure gold in g/cm³?
2.70
10.49
19.32
21.45
If the crown's measured density was lower than pure gold, what would that tell Archimedes?
The crown was too small.
The goldsmith used too much gold.
A cheaper metal was mixed into the gold.
The crown was made of platinum.
Why was it difficult for Archimedes to find the volume of the crown?
The crown was too big to measure.
Its irregular shape made calculations hard.
He didn't have the right tools.
The king wouldn't let him touch it.
What did Archimedes notice while taking a bath that helped him solve the problem?
The water became cold.
The water level rose when he got in.
He saw a reflection of the crown.
He felt lighter in the water.
What does the amount of water an object pushes aside tell us about the object?
Its weight.
Its color.
Its volume.
Its temperature.
What famous word did Archimedes shout when he made his important discovery?
Hooray!
Victory!
Eureka!
Amazing!
What did Archimedes discover about the king's crown after his measurements?
It was heavier than expected.
It was made of pure gold.
Its density was too low.
It was a perfect fit for the king.
Why was the crown's density too low?
It was made of a new type of gold.
The goldsmith mixed in a cheaper metal.
Archimedes made a mistake in his calculations.
The crown was too old.
