Construct a motorised DIY vehicle using power from a solar cell. Students can have fun building the sun powered motorized vehicle as they also learn how motors and automotive transmissions work. Watch the vehicle run at maximum power on a sunny day or minimum power on a cloudy day.

Set of 13 equally tempered tuning forks. Comes with a round-ended stick with one soft end and one hard end for use with all frequencies of forks.

This set contains 30 wheels of three different sizes, 35 metal hooks and 15 free running pulleys (1-wheel, 2-wheel and 3-wheel). Metal hooks can be attached to both top and bottom of pulley. String included.

A set of 4 different magnetic shapes.

This fun and educational magnet set allows students hours of active exploration of magnetic forces with the provision of different types of magnets and other apparatus.

A comprehensive kit consisting of 6 different types of magnets.

Two classic demonstrations using a pair of bottles. We supply two threaded connectors that connect a pair of plastic bottles mouth to mouth. One connector has a single hole; the other has two holes and plastic tubing. You supply the bottles and coloured water. With the single hole connector, you can create a vortex that simulates a tornado or waterspout by swirling a partially-filled bottle then setting it upright. With the two-hole connector you make Hero's fountain using the plastic tube and two partially-filled bottles. Air pressure from the water in the upper bottle drives the fountain.

Construct a self-supporting arch without buttresses of glue! This set's 13 shaped hardwood blocks allows your students to assemble a self-supporting arch based on the mathematical catenary curve. An arch built in the shape of this curve will support itself without glue or buttresses. Your students will prove this - with or without the supplied assembly template!

Easily determine vector-force relationship with this Low Cost Kit. This system makes it easy and fun for students to learn about the force of equilibrium. Students pull on three zero-adjustable dual-spring scales attached to the 20 cm-diameter protractor disk to measure the forces and angles necessary to achieve equilibrium. Measures forces up to 5N. Easy to set up and use. The apparatus contains everything needed including protractor, three spring scales and complete instructions.

Children will use problem-solving and engineering skills to build their very own clock which really works!

A fun way to explore the properties of air and water. Now students can make their own Cartesian Diver using this easy-to-assemble device and an empty 2 litre bottle that you supply. The diver consists of a plastic medicine dropper and a metal nut. The diver will float and sink depending on the water level in the bulb of the dropper. Students utilise this principle to try hooking the diver onto another object. Apply pressure to the outside of the bottle and watch what happens!

An educational electronic kit for children ages 7 and up. Easy-to-handle components snap together to create 188 circuits. Safe and easy to operate. Circuits activated by moisture, light, touch, sound and magnets; activating flashing lights, spinning fans and various sound effects. User's manual included.

Safe, solderless, educational and fun! Students build their own operational meter, generator, bell and motor with this 4 kit set. Students can experiment by controlling a motor's forward/reverse movement, ringing the bell with the generator and so on! Includes instruction manual. For ages 10 and up.

Easily read tubular body and scale with top suspension ring and load hook.

Easy for the entire class to see! Using Squidy and a 2 litre plastic bottle, students will have fun exploring the properties of air and water when pressure is applied. This Cartesian Diver is highly visible and economical. The Diver will float and sink depending on the water level in the bulb of the dropper. Instructions included.

Compass with luminous north needle and points.

General purpose funnels suitable for many types of liquids. Safe and easy to clean.

Set includes 50 wheels of four different sizes and 25 metal rods.

High-quality binoculars for use in all light conditions with independent adjustment on one eyepiece tube and an easy to operate focus control. Supplied with lens caps and a PVC storage bag.

Students can touch the plasma sphere and watch as streams of electrically-charged particles leap harmlessly around their palms and fingers. Used to demonstrate high voltage and high frequency currents.

This device demonstrates the construction and operation principle behind AC/DC generators. Simply turn the hand wheel and the bulb will light up.

A single pump to show hydraulic principles and measure hydraulic pressure.

The Mirage optical illusion is a perfect reflection and refraction demonstration for classroom. When students place an object inside, directly below the hole, the 'object' appears in the hole as an illusion!

A demonstration of an electrochemical cell. The LCD clock runs smoothly on two potatoes, fruits, plants, or eve fizzy drinks!

A stimulating addition to any lesson on energy conversion, electricity or magnetism. A slow turn of the handle will light dimly, turn faster and the bulb becomes brighter.

Anti-gravity globe use for demonstrating the effects of magnetic repulsion and attraction. Students can pass their hands above, below and around the globe as it continues to levitate!
