Comparing Lengths of Arms with Links
Put students in pairs and give each pair a package of commercially available links or large paper clips. Have each child use the
links to make a chain as long as his or her arm. Have students in each pair compare the chains to determine whose arm-chain
is longer (or shorter). Have students use the arm-chains to measure objects in the classroom. Have students compare their
results to reveal that, when measuring with non-standard units, the same object can be equal to different numbers of armchains. Have students read the book How Big Is a Foot?
Inch By Inch
Paper-Penny Boxes
Have students explore the concept of volume by building a paper box that will hold 100 pennies. This activity is based on the
Newberry Medal Award book The Hundred Penny Box. Have students discuss the strategies that they used to build their boxes.

Steel Heat
Put a sensitive thermometer in a jar and close the lid. Wait five minutes and record the
temperature. Remove the thermometer from the bottle. Soak half of a steel wool pad
in vinegar for one minute. Squeeze excess vinegar out of the steel wool pad and wrap
it around the bulb of the thermometer. Place the thermometer and the steel wool into
the jar and close the lid. Wait five minutes. Record the temperature. What happened to
the temperature?
Teacher’s Note:
Why did the temperature rise?
The vinegar removes any protective coating from the steel wool, allowing the iron in
the steel to rust. Rusting is a slow combination of iron with oxygen. When this
happens, heat energy is released. The heat released by the rusting of the iron causes
the mercury in the thermometer to expand and rise.
