Get your larger model rockets in the air with these popular rocket engines.

With the Large Plastic Dynamics Cart, students can explore the changes in motion that occur in a dynamics cart when different amounts of net force are applied.

The perfect kit for students and educators studying gravitational potential energy, translational and rotational kinetic energy.

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

Air Strike™ desktop catapult can launch the included foam balls as far as 40 feet. Simple to assemble, no tools required. Features super grip suction cups and a pivoting launch base.

Measuring apparatus for investigating the elastic deformation of rods of flat geometry and for determining the modulus of elasticity.

A set of 15 samples of different materials used to challenge students to identify materials based on measurement of their density. For some specimens this will be straightforward. In other cases, it will lead to a discussion of uncertainty in measurements and data, and to an awareness that different materials may have nearly the same density.

Gravitational Torsion Balance and He–Ne–Laser demonstrates gravitational attraction between two bodies and determines the gravitational constant.

Launch an egg and test recovery systems with this reliable, sturdy model rocket.

This model shows the internal structure and operating principles of an air cooled two-stroke engine. All parts are aluminum and plastic. Ignition is shown via a small bulb. Carburetor and fuel supply are also sectioned. Hand crank is provided for manual operation. Mounted on a base.

The Porta pad E launch system is large enough to accomodate those rockets that require larger, 24 mm E and F engines. It has a larger footprint for added stability and a larger blast deflector plate. The Porta pad E comes with the larger ³/₁₆" Maxi launch rod.

Most people are familiar with the key factors of hybrid technology: The engine and motor. However, most don't get a chance to peek inside of these key components while they're running to examine, assess, and diagnose.

We all wish we had our own hybrid automobile to take apart, re-purpose, and use to show others exactly how this fascinating piece of technology works. Just because this may not be a possibility for you doesn't mean you can communicate the basics of hybrid technology.

This product is a model of a wankel engine. The transparent plastic housing enables the students to see the internal structure at all angles. The rotor starts moving when the switch is turned on. It is powered by 110V AC. These items are made special to order and are not held in stock. Lead times are approximately two to three months. Freight charges may apply. Dimentions: Size: 15L x 20W x 28H cm ; Weight: 3 kg

This product is a small-sized model unit used for explaining the principle of a planetary gear. By setting the internal sun and pinion gears into motion (input or fixed), you can get the different outputs from acceleration, deceleration and reverse. Comes equipped with a storage case holding 10 Planetary Gear Demonstrators. These items are made special to order and are not held in stock. Lead times are approximately two to three months. Freight charges may apply. Dimentions: 24L x 14W x 14H cm ; Weight: 3kg

A set of dynamic cart trolleys are used for investigation on momentum, velocity and acceleration. Each trolley consists of two rectangular wooden blocks, 300 mm long, moving on three low friction wheels (ball bearings in wheels). The trolley is fitted with spring loaded impulse rod. It has a provision for stacking the trolleys on top of each other with removable pins. It is supplied with two rubber corks and 2 needles, so trolleys may be stuck together for inelastic collisions. A striking pin for releasing the striker and 3 pins or dowels for stacking are provided. One trolley weight approximately 1 kg.
