Physical Science
Density And Specific Gravity
12-Piece Mystery Density Set
This set of 12 samples represents two sets of materials
(nylon and acetyl) that, while sharing similar physical appearances,
represent differing densities. The set is meant
to be used as an inquiry lesson in which students are
asked to measure and graph the masses and volumes of
all 12 pieces without the knowledge that the 12 samples
actually represent two different substances. Proper analysis
of the graph will point students to the conclusion that
there are in fact two substances of differing densities. Use
to introduce the concept of density; to reinforce the basic
principle of graphing data as a means of data analysis; and
to test students’ abilities to properly collect dimension,
mass, and volume measurements. Additional material may
be needed. Ideas for supplemental activities are included.
Grades 7—12. Sh. wt. 1.25 lbs.
SB47733M — $40.80
Equal Mass Cylinder Density Set
Demonstrates the inverse relationship between density
and length for cylinders of the same mass and diameter.
The set consists of five cylinders (copper, aluminum,
nylon, polyvinyl chloride, and polyethylene) all 12 mm
(½") in diameter and range from 15 mm to 100 mm in
length. Mass of each cylinder is 15 g. Sh. wt. 0.11 kgs.
SB15356M — $13.05
Density Cube Set
Here’s a handy, economical set of 10 one-inch cubes in
the following materials: aluminum, steel, brass, copper,
acrylic, oak, nylon, pine, poplar, PVC. Experiment with
mass, volume, density, buoyancy, specific gravity, and
floatation. Instructions included. Grade 3 to adult.
Sh. wt. 2.27 kgs.
SB31356M — $38.05
12-Cube Set. One 1” cube each of the materials listed
above, plus lignum vitae and polypropylene.
Sh. wt. 1.75 lbs.
SB45884M — $38.05
Density Ball
Used to demonstrate
the effects of tem-
perature and mineral
content on density.
The metal ball will
float in cold water
and sink in hot!
Sh. wt. 1.50 lbs.

Equal Mass SG Metal Cylinder Set
A metal cylinder set of 5 different materials: aluminum,
copper, lead, tin, and zinc. Each are machined to an equal
mass on a computer-controlled turning center and their
metal is identified with a stamped symbol on one end.
Since each specimen weighs the same and all are ½" dia.,
this set is ideal for demonstrating reciprocal density and
for computing the specific gravity of each element.
Sh. wt. 0.20 kgs.
SB26243M — $13.05
Density Identification Set
With this clever kit, students try to identify each of 12 different
samples by determining their density. Each cylinder
varies in size (volume) and density, but has the same
diameter of ½". Lengths vary between 1 9 ⁄16" and 2 5 ⁄8".
Includes: 12 of the most common materials, wood base,
and instructions. Grades 6—12. Sh. wt. 0.48 kgs.
SB39210M — $47.55
Specific Gravity
Metal Specimen Set
Four cylinders of copper,
brass, steel, and aluminum. 7
mm dia. x 50 mm long.
Sh. wt. 0.23 kgs.
SB10371M — $11.45
Set of 18 Density Blocks
Excellent for experimenting with density and volume.
Includes 10 mm cube, 20 mm cube, and 30 mm
x 20 mm x 10 mm block of six metals: aluminum,
brass, copper, lead, steel, and zinc. Sh. wt. 2 lbs.
SB45749M — $47.55
Density Cubes
Set of four 1" density cubes containing one each of nylon,
acrylic, aluminum, and pine wood. Grades 6—12.
Sh. wt. 0.31 lbs.

Diverse Material Equal Volume
Specimen Set
This equal volume set is comprised of four ½" dia. cylinders
of widely diverse materials: aluminum, glass, plastic (PVC),
and wood. The set is used for specific gravity, as well as
measurement education. Each specimen is 5 cm long and
the set comes in a reclosable poly bag. Sh. wt. 0.17 kgs.
SB26242M — $13.70

Drilled Ball Set
Ideal for collision and pendulum
applications, this ball set consists of 14 balls of seven
materials. Includes two balls each of aluminum, brass,
copper, iron, lead, zinc, and wood. 1" each.
Sh. wt. 2.25 lbs.
