Density Cube Set
Here’s a handy, low-cost set of 10 one-inch cubes
cut from modern materials. Use these precision
cubes to perform a variety of density experiments.
The set contains one cube each of aluminum, steel,
brass, copper, acrylic, nylon, poplar, oak, willow and
polyethylene.

AP6058 Density Cube Set $40.00
Reverse Density Rod
The “normal” density rod (AP4632) sinks in warm water
and floats in cold water. The reverse density rod works just
the opposite! It will float in water 30–35 °C and sink in cool
water! Using both rods will enhance your ability to make
density meaningful to your students. The reverse density
rod will force students to think about the concept of density
in a very fundamental way. This demonstration will also
dramatically call attention to the fact that the properties and makeup of the rod as
well as the properties of the liquid must always be considered.

Specific Gravity Metal
Specimen Set
Four different metal cylinders for use in measurement
and density experiments. Their small size (5 cm long
x 1.3 cm diameter) makes them perfect for use in a
graduated cylinder. Includes copper, brass, aluminum
and steel.

Galileo Thermometer
Each bulb in the thermometer is partially filled with
a different colored fluid and a metal tag beneath it
with a printed Fahrenheit temperature. The bulbs are
in continual motion up and down the column as the
temperature changes. The current actual temperature
is indicated by the lowest floating sphere in the upper
part of the cylinder. Two sizes are available.

Metal Density Cube Set,
Economy Choice
Students measure the densities of the four metal
blocks and then determine their composition. The
four cubes in the set are aluminum, steel, copper and
brass. Instructions are provided.

Steel Sphere Density Set
Boggle your students’ minds with this fun density set! Both
spheres weigh the same, but have different volumes. Which will
sink? Which will float? Have fun discussing density, mass and
volume with this density set!

AP9910 Steel Sphere Density Set $33.16
Density Rod
Simple device with a multitude of demonstration possibilities. The rod responds
to changes in density of a liquid by sinking or rising in the liquid. As the
density of the liquid is changed, the rod moves up or down accordingly. It
sinks in warm water but floats in cold water. A temperature gradient in
a column of water will find the rod held in suspension somewhere
in the middle. Put the rod in alcohol and it will sink. Add different
amounts of salt to water and the rod will rise or sink as
the density changes. Comes with instructions and detailed
explanation of density theory. 6.5 cm long, 1.9 cm diameter.

Density Cube Set of 24
Use this density cube set, comes in various samples of
the same material ranging in sizes from small to large,
for density experiments. Available in eight different
materials: acrylic, aluminum, brass, copper, nylon, polypropylene,
PVC, and steel. Each material is represented
by a ½", 1" and 1½" cube.
