Best of Luck!!

🙂

When a solid is added to a cup of water, coke, or any liquid, we see that the liquid increases.

🙂

An object floats as it is less dense than the buoyant force. If the object is heavier or stronger than the buoyant force, it will not float.

As the weight in the bottle increases, it starts to sink as it is denser than the water it is floating on. 

A ship floats on water

ARCHIMEDES' PRINCIPLE and 

BUOYANT FORCE

Let's restate...

Archimedes' principle, physical law of buoyancy, discovered by the ancient Greek mathematician and inventor Archimedes, states that any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant force, the magnitude of which is equal to the weight of the fluid.

snapped

upthrust

LET'S LISTEN TO THE POEM!

Did Archimedes discover the phenomenon of buoyancy by chance or on purpose?

CHANCE

ON PURPOSE

When did the king feel that the goldsmith had cheated him?

Let's recheck

The king caught the goldsmith’s eye as he was delivering the crown and it seemed to the king that he was being lied to.

'DRAG AND DROP'

forge a crown with a lump of gold he provided

the volume of an object

he climbed into his bath and observed water being displaced

The king of Sicily asked the goldsmith to _______.

He had found out a way of testing  _______.

Archimedes understood the principle related to objects immersed in liquids when _______.

Archimedes was successful in confirming the King's doubt that the goldsmith had indeed mixed a cheaper metal into the gold.
State True or False.

1. True
2. False

Why did Archimedes leap out of his bath and what did he do?

Let's recheck

The king caught the goldsmith’s eye as he was delivering the crown and it seemed to the king that he was being lied to.

The rhyme scheme of the poem is

1. aabb
2. aabc
3. abcd
4. abbc

Identify the poetic device used in given lines:
"He suddenly snapped, and let out a scream..."
"What various metals the crown could contain...."

1. Simile
2. Metaphor
3. Hyperbole
4. Alliteration

Identify the pair of rhyming words in the given lines.
The goldsmith's eye made the King suspect
That he'd made up the weight with some cheaper metal
And stolen some gold, that his debts he might settle.
