Making Cents of Density
- Collect the following materials:
- At least 28 coins of the domination you are
assigned (0.01, 0.05, 0.10, 0.25)
Note: If you chose pennies, they should all be pre 1982 or post 1982 - Massing device up to 200 grams
- Meter stick or millimeter ruler
- Optional: 100 ml graduated cylinders with H2O to measure volume by displacement
Making Cents of Density
In this activity, students will measure the mass and volume of several collections of a coin type and enter the data into their handhelds and explore for patterns. Students will also make a plot of mass vs. volume and create a mathematical model that demonstrates the relationship between mass and volume.
