A simple kit that helps explain to students the principle of reflection and refraction. Using mirrors, lenses, acrylic prism sets, and a ray box, light can be reflected and refracted in different ways. The acrylic prism set includes a triangular, half-round, double convex, and rectangular prism and two double concave prisms all packed in a wooden storage box. A Newton…
A high-quality apparatus to determine precisely the co-efficient of expansion of various metals. An aluminum channel carries a 60 cm long metal rod enclosed in a heating jacket having three nipples for water intake, water outlet, and thermometer insertion. Dial indicator is a precision instrument sensitive to 0.01 mm/division and is securely mounted. As the apparatus works with hot water,…
Compact loupe magnifiers. Markings in both inches and centimeters for easy measuring. Fold flat for storing when not in use. Sturdy plastic frame. 1.25" x 7.8" when folded flat.
Understanding the principles of physics that occur on a roller coaster has become easier. This triple play apparatus consists of three tracks, one straight down, one with one loop, and the third with two loops. All three have different straight-up track lengths. At the end of each track is a catch sack to prevent losing the ball. The straight track…
To demonstrate the conservation of energy, conservation of momentum, and projectile motion. Consists of a metal track to drop a steel ball, and a circular scale for measuring the angle at which the ball drops. Includes two steel balls and instructions. Size: approx. 110 cm L.
The set consists of two plastic, 10cm-diameter hemispheres. Each half has a wooden handle firmly attached to it. One of the hemispheres has a raised edge to hold a rubber seal, while the other hemisphere has a stopcock for attaching to vacuum tubing. Join the hemispheres, hook them up to a vacuum pump, and evacuate the air inside the hemispheres.…
The transparent acrylic chamber contains iron filings. Chamber also has an internal tunnel into which a bar magnet can be inserted to demonstrate a magnetic field pattern. Other shaped magnets can be investigated by positioning their poles near one side of the chamber. With a Cylindrical magnet.
Consist of a closed transparent box with a transparent tube through the center. The box contains iron filings and silicon oil. When one or more cylindrical magnets are inserted into the central tube, the filings are attracted and lined up along the field lines in all dimensions. With Cylindrical Magnet.
A quick and clean way to visualize magnetic fields. The unit is a transparent acrylic case that holds iron filings in a fluid of proper viscosity. The unit can also be placed on an overhead projector for classroom demonstration. Unit measures 8”x 4-1/2” x 3/8”. 11oz. Ages 10+

The Random Oscillating Magnetic Pendulum (ROMP) is a popular desktop toy. It consists of a pendulum, with a small magnet attached to the end, which can swing freely over a metal base. On the base, there are nine numbers of strong, disc-shaped magnets, which act on the pendulum with either an attractive or repulsive force. When the pendulum is displaced…
Strong Ceramic magnets sealed in unbreakable colorful plastic cases. The North and south poles are located on opposite faces for ease of use. Can be used to determine if an object is magnetic. A pair of magnetic wands can be used to demonstrate attraction and repulsion between poles. The wand measures 7.5" x 1". Ages 7+

Use the magnetic wand with the 6 magnetic marbles included to perform the 4 simple experiments given or to independently explore magnetism. Make your own magnet to discover what magnetic poles are and where they are located. Wand and marble colors vary in each kit. Activity guide included. Ages 7+
Pocket type magnifier mounted in single body with a metal cover which doubles as a handle fitted with a single lens of diameter 18 mm with a magnification of x 10.
A fun way to learn about velocity and acceleration. Launch marbles at five different speeds. The safety guide is printed directly on the hardwood marble launcher's surface. A protractor is built into the launcher. Includes two marbles and an experiment guide. 16 in. L c 10in. W x 11-1/2 in. H.
Useful for demonstrating momentum, conservation of energy and torque, a large flywheel suspended by two strong cords. The cords are wound around the shaft of the wheel and then released. The wheel will unwind as it falls, but will wind itself back up as the momentum carries the wheel upward in the opposite direction. This oscillation process will continue for…
A component part of many kits, this pre-assembled miniature motor operates on 1.5V or 3V DC. RPM is between 7,000- 11,000. Comes with 12" red and black leads. Ages 7+
