Supplies

- plastic block

- wooden block

- oddly shaped plastic

- 100 mL graduated cylinder

- Ruler

- top loading balance

- calculator

Volume of sphere = 4/3 pi r^3

Activity

1) determine via measurement the volume of plastic box

- note box identity

- confirm volume by partner doing the measurement as well.

2) determine via measurement the density of wooden block

- note block identity

- confirm density by partner doing the measurement as well.

3) Density of a cylinder?

- Volume of cylinder = pi r^2 h

- optional

4) Density of sphere?

- Volume of cylinder = 4/3 pi r^3

- optional

5) determine via measurement the density of the oddly shaped piece of plastic

- confirm density by partner doing the measurement as well (optional)
