PHYSICAL SCIENCE
Student Magnetic Field Demonstrator
Iron filings sealed in the circular plastic transparent case respond to magnets
placed on the flat outer surfaces. Magnetic force lines are easily viewed and
maintained while students record results. Includes bar and disk magnets.
AP6077—$8.55
Collapsing Can—Demonstration Kit
This demonstration with more than 1,800 lbs of force convinces students that
air exerts significant pressure. Heat 1 cm of water in a can then cap it and watch
and listen to the can collapse as a vacuum forms inside as it cools.
AP4695—$13.05
Mysterious Glowing Ball
Students see a glowing ball that appears to give off white light, but when it is
spun, they observe red, blue and green. Great for discussing the components
of visible light or how humans see colors.
AP9996—$6.95
C
C. Newtonian Demonstrator
Illustrate Newton’s laws of motion and the conservation of momentum. The
large swinging balls can be manually aligned to produce nearly perfect elastic
collisions. High-quality wooden construction. 7" x 9" x 8½".
AP6913—$36.00
Wave Demonstrator
Make waves by using this 1.8-meter helical spring to demonstrate standing,
transverse and longitudinal wave properties.
AP9023—$28.35
Solar Bag
This 50-foot-long, 3-foot-diameter black plastic bag holds 350 feet3 of air. Fill it,
tie off the ends, and let the Sun heat the air. In 10 minutes, the bag rises.
AP4622—$22.90
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 set!
AP9910—$29.95
Gravitron Space Gyroscope
Introduce Newton’s theories of gravitation and laws of motion in a simple,
entertaining way. Get several for class games and competitions or compare it
with a classic gyroscope. 6" H x 3" W x 3" D.
AP9967—$11.40
Diving Eggs Inertia Challenge—
Newton’s First Law Demonstration Kit
Present a dramatic demonstration of Newton’s law of inertia by dropping three
eggs into beakers of water without touching the eggs!
AP7419—$19.05
Sonic Flame Tube—Demonstration Kit
Students visualize waves and resonance as natural gas flows through a 3-foot
aluminum tube with predrilled, evenly spaced holes and then is ignited. A
speaker sends frequency sound waves through the tube, creating resonance.
AP7363—$75.90
