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!
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 diam- eter) makes them perfect for use in a graduated cylinder. Includes copper, brass, aluminum and steel.

Galileo Thermometers
Density Box—Demonstration Kit
Students watch with amazement as warm water rises and cold water sinks in this clever demonstration of density. Hot, red water is placed on one side of the clear acrylic chamber and cold, blue water on the other. The center dividing wall is then carefully removed, allow- ing the two solutions to mix. A great demonstration when discussing convection currents, air turbulence and water turnover in lakes and ponds.
