Internal Combustion
Engine Model
Gasoline Motor
Highly-detailed engine model perfect for any
technology, physics, or general science classes. Fourstroke
operation is demonstrated by the gear-driven
timing mechanism, valves, ignition system, and
more. DC power input is available to power a lamp, if
desired, to represent the spark or glow plug ignition.
Grades 7—12. One-year warranty.
Sh. wt. 1.59 kgs.

NASCO Buoyancy Experiment Kit
Explore the factors that cause objects to float or sink. Students also experiment to
investigate how shape and weight affect buoyancy. Kit contains: clear plastic box (5- 1 ⁄8”
x 5- 3 ⁄8” x 1- 3 ⁄8”), aquarium (½ gallon, 5- 3 ⁄8” x 7” x 3-¾”), 30 red crayons, pencil, paper clip,
seed, rubber band, clay, salt (26 oz.), six dishpans (13-½” L x 9-½” W x 4-¾” D), paper towels,
40 marbles, 30 washers, unpopped popcorn (2 lbs.), and 30 Alka-Seltzer® tablets.
Grade 5 and up.

Four Stroke Engine Models
Learn how engines work by studying the
internal workings. Turn the crank and see the
intricate parts move. Ignition is shown by means
of a miniature bulb. Diagram on front clearly
delineates each part and its location on the
model for easy reference. Mounted on base.
Grade 7 and up.
Gasoline Engine Model. Represents a typical
air-cooled, side-valve, four-stroke gasoline
engine. Cams are driven by a gear train from
rear of the main crank. Screw terminals are provided
for connection to 3V battery. Sh. wt. 5 lbs.
SB48290M — $122.90
Diesel Engine Model. Represents a four-stroke
water-cooled diesel engine of the chain-driven,
overhead camshaft variety. The functioning of
fuel injection system is also represented.

High Quality Stirling Engine
This affordable Stirling Cycle Engine
measures 7" x 4¼" and comes complete
with built-in alcohol burner. Red flywheels
and chassis mounted on a green base, this
all-metal engine runs silently at speeds in
excess of 1,000 RPM and is sure to attract
your student's attention and inspire awe.
This model comes completely assembled
and ready to run, accompanied by Stirling
Cycle Engines book which explains the
principles of operation. Sh. wt. 2 lbs.
SB43624M — $224.65
NASCO Speed of a Bubble Tube Test
An effective introduction to proper techniques of graphing and a powerful way to
connect a physical science concept (velocity) with a mathematical idea (slope). Three
transparent plastic tubes containing coloured fluids of three different viscosities illustrate
how a bubble in each tube rises at a constant speed which depends on the type
of fluid, the angle at which the tube is inclined, and temperature. Reproducible pages in
the instruction manual guide students through the steps of data collection and analysis.
Follow-up questions, as well as notes to the teacher and answers are also included. Set
includes three “speed of a bubble” tubes and instruction manual — the only additional
items needed are a metric ruler and a clock with a sweep second hand. Grade 8 and up.
Sh. wt. 0.48 kgs.

Nearly 200 demonstrations in physical
science to engage and enlighten students. Each
activity is designed in an easy-to-follow, concise format,
including application, theory, materials, safety
precautions, procedure, chemical disposal information,
and references where available. Concepts
covered include: waves, sound, and light; Newton’s
laws of motion; electrical charges and currents; force
and mass; heat energy; properties of matter; work,
power, and simple machines; atomic theory and
bonding; classification of matter; energy and motion;
magnetism; and the nature of a gas. Grades 8—12.
