Converter - Demonstration Model |
|
|
|
Ever
wonder how your car works? The Motion Converter shows how the power
generated by the pistons in your engine transfer to the wheels, making
them turn round and round. Includes a detailed activity guide which
details the history of the model, practical applications, and classroom
experiments. 39" x 12" x 5". |

Train – Demonstration Model |
|
|
 |
A
system of two or more toothed wheels meshed together so that the motion of
one directs the others to employ a force in a direction in which the
resistance is to be moved. Includes a activity guide which detail the
history of the model, practical applications and classroom experiments.

| Screw
– Demonstration Model |
|
|
 |
Each
Demonstration Model measures approximately 2-1/2 times the size of the
student version and is great for classroom demonstration. An example of a
simple machine, which converts a circular motion (the turning of the
screw) into a linear motion. It also lets you amplify the force a great
deal, since turning the screw only moves the end of the screw a small
amount. Includes a detailed activity guide which details the history of
the model, practical applications, and classroom experiments. 19-1/2"
x 10" x 4".

| Newton's
Cradle |
|
|
|
Demonstrates Newton’s Third Law of Motion and the
principles of conservation of momentum. This law states that action and
reaction are equal and opposite. The unit consists of a walnut support
with five nickel-plated steel balls. Dimensions are 9" x 7" x
8" H overall. |

| Drinking
Bird |
|
|
|
Almost everyone
remembers this hard-to-find toy with at least a twinge of nostalgia - now
he's back, disguised as a great physics demonstration of heat and
thermodynamics. This lugubrious little lorikeet dips his beak into a glass
of water as evaporative cooling induces the rise of a volatile liquid from
his tail toward his head. As he dunks, the liquid returns to his tail, the
bird rises, and the process begins again. |

be amazed at the beauty of these blown glass pieces, handmade in Germany
by skilled artisans. These Drinking Birds are worthy of displaying in your
classroom or home. They're also perfect as gifts for honored teachers or
students. Birds come complete with glass stands and cup. |

Hand Boiler |
|
|
|
This energy
transformation is sure to capture your students' attention! Hold the glass
vessel in your hand, and your body heat causes the liquid inside to appear
to boil and shoot into the top bulb. Challenge your students to explain
the rapid change. Assorted colors and styles. Hand Boiler is 7 inches
tall. |

Newton's Apple |
|
|
|
Would you know
a Newton if it hit you in the head?
Sir Isaac Newton himself was inspired by the fall of an apple when he
developed his theory of gravity. Your students can perform their own
gravity and motion experiments with Newton's Apple! Of course, it
has a weight of exactly one Newton (108g) and is made of soft foam, in
case you want to act out the story that started it all. |

Periscope |
|
|
|
Periscopes, including this one, can help you see around
barriers. But what if you want to see something behind you? Submarine
periscope operators walk in circles, turning the whole periscope. Why not
just rotate the top mirror? Try it with this rotating periscope, and
you'll see that the image of everything behind you is upside-down! An
elegant demonstration of basic plane mirror reflection, this is also a
great way to test student understanding of image formation. |

|
When
pigs fly! A fun lab on centripetal force.
Add some excitement to your lessons on circular motion with the Flying
Pig. Suspended from the ceiling, his wings flap and carry him in a regular
circle. With the string, this motion gives students a conical pendulum and
a perfect opportunity for quantitative measurements of circular motion.
Lab instructions included.

| Balancing
Soda Bottle Kit |
|
|
|
It's the balancing bottle trick
using a 2-liter soda bottle. The hole in the acrylic board is just large
enough to fit the neck of a 2-liter soda bottle. Slip the bottle through
the hole and try your hand at balancing the bottle on the bottom edge of
the board. It looks and feels impossible until you finally let go! The
bottle appears to defy gravity as it balances in a most precarious
position. Don't let the sounds of "ooohs & ahhhs" drown out
your lesson on the center of gravity.
What's included?
The kit comes complete with a precision cut balancing
board, an empty 2-liter soda bottle, a science display box and an activity
guide with great extension ideas.
How does it work?
It's truly a lesson in the center of gravity. When the
center of gravity of the entire set-up is directly above the base of the
board, the “system” (the board and soda bottle) will balance itself.
When the center of gravity is not directly above the foot of the base, the
system is unstable and falls over.

| Solar
Radiometer |
|
|
|
A radiometer is a large glass
bulb or sphere with a mast running up the middle. Four diamond-shaped
"sails" balance near the top. As the sunlight hits these flags,
they begin to turn. In bright sunlight, they really spin fast! It's an
amazing experiment in solar science and the nature of light!
How does it work?
The glass bulb of the radiometer is sealed so that a tiny
bit of air is trapped inside. This partial vacuum allows the flags to turn
freely, without too much drag. Notice that the flags have one shiny side,
and one black side. When the light hits the flags, it is reflected off the
shiny sides, but absorbed by the black sides, which raises their
temperature. When the black sides of flags heat up, the air near them also
heats and the excited air molecules exert a tiny bit of pressure on the
flags from one side. This small difference in pressure is enough to make
the sails spin!

| Concave
& Convex Mega Mirror |
|
|
 |
These
extra-large parabolic mirrors make demonstrating optical principles a
snap. One example? The concave mirror can demonstrate the reflection and
focusing of light, heat, and even sound. A discussion of shapes and uses
of satellite dishes can be visually demonstrated. The mirrors' extra-large
size makes your demonstrations easy to see and understand, even from the
back of the lecture hall.
Each
silver-backed, non-aluminized mirror measures 24" in diameter and is
supplied with an aluminum frame, mounting bracket, and base. The surface
has been highly polished for accurate reflection. Order them and see why
Professor Peter Kinsler of Howick College said, "I recommend them
unreservedly to all physics and science teachers." Includes
demonstration guide.

| Magic
Mirror |
|
|
|
This deceptively simple device
creates three-dimensional real images of remarkable optical resolution and
startling clarity. Precision-mirrored coating faithfully reflect
untouchable objects of your choice to an amazed class. It's ideal for a
wide range of experiments illustrating the difference between reality and
sensory perception. Comes with a confidential owner's manual that reveals
the secrets of the illusion and details of the unusual effect. Dimensions:

| World's
Simplest Motor |
|
|
|
Wrap the wire around a D-cell battery, scrape
the ends and the coil is ready to go in one of the world's easiest motors
to build. The principles of magnetism can be demonstrated as the coil
becomes energized in each rotation and pushes against a mounted ceramic
magnet with enough energy to keep it spinning. Additional experiments are
suggested for hours of fun and learning.
