You're So Dense - TI-83

Activity Overview

Students investigate the relationship between density of an object, its mass and its volume. They use mass and volume measurements to determine the density of pennies. They compare the density of pre-1983 and post-1984 pennies.

Before the Activity

Set up the calculator for data collection using the procedure described in the attached Appendix PDF file

See the attached PDF file for detailed instructions for this activity

Print pages 71 - 82 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Fill a 50 mL graduated cylinder with water to the 20 mL mark and measure its mass

Add 5 pennies (pre-1983) to the cylinder, record the mass and note the volume

Repeat the step, adding batches of 5 pennies (until 25 pennies have been added); record the mass and volume after each addition

Calculate the density of the pennies

Repeat the activity with 25 post-1984 pennies

Calculate the density of the pennies

Compare the density data

Measure the volume and density of another set of 15 pennies

Use the data to determine the density and categorize the pennies

Given the mass of the pennies, predict the volume

Given the volume of the pennies, predict their mass

After the Activity

Students will complete the Data Collection and Analysis page and answer questions listed on it.

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
