Arquímedes and the Density.
As we know, matter is the substance that an object is made of. All matter has two physical properties: mass and volume.
The density of a substance is the relation of its mass to its volume.
Look at the video, copy and answer the questions in your notebook:
1-. Who was Arquímedes?
2-. How did he find out the relation between mass and volume?
3-. How did he demostrate that the crown was a fake?
