Work: Plane And Simple
Students investigate the difference between inclined planes and screws.
They measure the force required to lift objects. They explore the amount
of work needed to move objects. Each kit contains enough materials to do
the experiments repeatedly, a materials list, an activity guide,
instructions for 8 to 12 learning packed activities, safety instructions
for children to follow, background information and more! This fun-filled
kit comes packaged in a sturdy, plastic container that makes storage a
breeze! Sorry, we don't have a picture available, so used
the one for Clever Levers, which shows extensiveness of these kits.

Inclined Plane Kit
For determining the coefficient of kinematic and static friction,
mechanical advantage and efficiency of an inclined plane. Comprised
of a hardwood inclined plane (600 x 100mm) fitted with a pulley at the
free end. It is hinged to a horizontal polished wooden base, which is
fitted with an aluminum arc graduated both vertically and angularly.
The inclined plane can be fixed at any angle up to 45 degrees or at a
suitable height with a clamping wing nut. Supplied with a
cylindrical plated metal roller, two wooden blocks, a steel block and
scale pan, cord and hook.

Inclined Plane Friction Kit
This device is used to study the friction between two surfaces and the
forces on an inclined plane. The inclined board can be set at any
angle been 0 and 45 degrees. A hanging pan is provided to hold the
desired weight. Two wood boards with different sizes and metal plate are
included. You can determine the coefficient of static friction and
the coefficient of sliding friction and verify the normal and frictional
components of the force exerted by the plane. Comes with extensive Instruction
Manual.
No. SK290-PF. Only $54.95

Double Cone and Incline
For the dramatic and puzzling visualization of the effect of change of
center of gravity of an object. Consists of a pair of wooden double
ended cones, a wooden diverging bar 0 to 10cm wide, that serves as an
inclined plane. When the double cone is set on the bars of the
incline, the cone appears to roll up the plane, violating the law of
gravity. This is possible because the axis of the cone is
actually moving downward due to a widening of the track.
Fascinating.

ABS Inclined Plane
This rigid four foot heavy duty steel pane is finished with a heavy coat
of baked enamel. It features two screws to adjust level and
facilities for the mounting of a pulley set. Often used in
conjunction with the Multipurpose Cart for experiments in
kinetic energy. Does not include cart.
No. SK290-DE. Only $34.95 |

Multipurpose Cart
This is little vehicle that. can be used in a variety of experiments including
investigations of speed, circular motion, velocity, time, force, mass,
acceleration and kinetic energy. Fabricated out of ABS resin and
steel, this versatile cart measure 3.25" x 8" and is virtually
indestructible. Features built-in receptacles to receive up to three
hexagonal 1/2 kg masses. Comes with a motor mount and water clock.
Middle and High School.
No. SK290-CA. Only $32.50
Halls
Carriage
This durable carriage has a one-piece high impact plastic body. the
machined aluminum wheels and axles are mounted on hardened steel cone
bearings for minimum friction and long life. Designed to be used
with all types of inclined planes. 5.75" long
No. SK290-CB. Only $14.95 |

Friction Apparatus
This set includes a friction block and a friction board, both made
of high quality, smoothly finished pine wood. The friction
block has a hook for a spring scale and two compartments for
additional weights. It can be placed face up or sideways.
You can vary the weight or area of contact to see how they impact
the friction force. Comes with three 50 gram weights and 100g
spring scale. Board is 10" x 2". Block is 4 x 1.5" x 1.
Comes with comprehensive study manual.
No. SK290-FA. Only $29.95 |

Linear Motion Apparatus
This unit is designed for use in the study of motions in a straight
line, including the motion with constant speed and the accelerated
motion. A trolley cart can move on a nearly frictionless horizontal
or inclined track, with or without driving force. The
distances the cart travels every 1/60th of a second are recorded on
a tape by a spark timer (included). You can analyze the data to
determine the velocity and/or acceleration for each motion.
30" x 6" x 7". Instruction manual included.
No. SK290-MA. Only $179.95 |
