Density - Archimedes Principle
Students watch a short video from a TED-animation about how Archimedes "discovered" the principle named after him. This activity helps to introduce students to a lesson on density.
The author says that some of the best opportunities to learn are the moments in which we are...
Archimedes is an ancient mathematician and inventor. His discoveries are still important, and we use them today. What is an example of another discovery that Archimedes made that is still used today?
Name other people from ancient history that have made important discoveries.
When and where was Archimedes born?
List five objects that you think are more dense than water.
How will you test your prediction about the five objects?
How will you determine which objects are the most dense?
What determined how much water was displaced from Archimedes bathtub?
What are some practical applications for Archimedes' Principle. Why do you think it's so important?
What property did Archimedes need to determine in order to solve the king's mystery?
These days, using the way an object displaces water to determine volume is called:
Collect a rock from your teacher and determin its density using the form below.
What was the density of your group's rock?
(remember to use units and sig figs)
Show how one would set up a ratio to determine the mass of a substance with a density of 8.2 g/mL and a volume of 2.0 mL. Determine the mass
What was your final answer with units?
Show how one would set up a ratio to determine the volume of a substance with a density of 4.2 g/mL and a mass of 8.6 g. Determine the volume.
What was your final answer with units?
Density of water is 1 g/mL or 1.0 g/cm^3
What is the volume of a sample of water if the mass is 6 g? Explain why this is so easy to figure out?
(Hint: think ratio)
