  • Coins
  • Dime
  • Nickel
  • Penny
  • Quarter

Materials

  • 1 set of coins per pair of students consisting of 1 circulating U.S. penny, nickel, dime and quarter per set (4 coins)
  • Magnifying glasses or stereomicroscopes
  • Lab notebooks
  • Pencils
  1. Divide the class into pairs of students. Give each pair one set of four coins, one of each of the lowest denominations. Have them record various visible characteristics for each coin in their lab notebooks.
  2. Once the students have made their initial observations, have them use hand-held magnifying glasses or stereomicroscopes to make more detailed observations.
  3. Have the students make graphite copies (pencil coin rubbings) of the coins by placing thin white paper over the coin and lightly rubbing the side of the pencil point across the covered coin. The details of the coin will be shown through the graphite on the white paper.
  4. Have the student pairs share with the other pairs the coin specifics they have determined.

Differentiated Learning Options

Give students data about “unknown” coins. Using knowledge the students gained previously, have them identify what type of coin the information describes.

Evaluate the lab notebooks to see whether the students have met the lesson objectives.
