Task: At this station, you will be determining the density
of a sinker.
Materials:
- Spring scale or balance
- Graduated cylinder
- Beaker with water
- Sinker
- Calculator
Directions:
- Find the mass of the sinker. Include units in your answer.
- In the space below, describe the procedures you will use to
find the VOLUME of the sinker.
- Find the volume of the sinker. Include units in your answer.
- What is the density of the sinker? Round to the nearest tenth.
Include units in your answer.
Show your work in the space below using the formula:
Density = Mass/Volume
- Suppose you cut the bottom half off the sinker. What would
be the density of the upper half of the sinker? Explain your answer.
