The Archimedes principle -
Taking a bath to find the density of objects
Taking a bath to find the density of objects
1
- Write down what the king wanted Archimedes to find out and why.
- Describe which physical quantity of the crown he had to determine and why.
- Name the two quantities that Archimedes had to measure to find the density of the crown.
2
Now you: find out the density of objects in the PHET simulation. You will find the link in the second box below. There are three categories: intro, compare and mystery. Fill in the table for each category. You can find them on the next side.
Video: How taking a bath led to Archimedes' principle - Mark Salata
Archimedes was summoned by the king to investigate a suspicious goldsmith about his crown. Did the goldsmith mix silver into it?
PHET-simulation on density
There are three categories that you can find below. Intro, compare
and mystery. Fill in the according tables with the help of the
simulation.

Intro
Look at the density of water and floating objects. Why can they float whilst others cannot?
You can hold floating objects under the water with your mouse to measure their volume.
Part 2: Compare
