Earth is constantly changing massive pieces of its outer layer are slowly sliding under, over, away from, or past each other. Earthquakes shake the continents and oceans, and volcanoes spew out the molten insides of our planet. By studying these awe-inspiring and devastating natural phenomena, you can learn more about the inner workings of Earth. A full-colour, 48-page experiment manual is included. • Build and erupt model volcano with plaster-based ""lava"" that hardens after each eruption. • Volcano can be erupted multiple times volcanic cone builds up with each eruption, like real volcano. • Learn about the different types of volcanoes. • Build working seismograph and simulate earthquakes to see how scientists measure earthquake forces. • Discover plate tectonics, and see how volcanoes and earthquakes are caused by the constant movement of the planet's parts. • Assemble plate tectonics puzzle and geological globe. Play volcano quiz game to learn about well-known volcanoes.

This gobe has striking cartography and features raised relief on the landmasses to give tactile indication of the location of the world's mountain ranges. It also uses raised relief to portray the ocean depths, revealing the trenches and mid ocean rises, which are important to the understanding of plate tectonics and oceanography. The ocean mapping also shows the direction of major currents, which is useful for an understanding of climatology and meteorology. • 300 mm diameter • Over 4000 place names and pieces of information • Suitable for advanced geographic study • Graduations on meridian help to work out lines of longitude latitude • Includes time dial to calculate different time zones • Available mounted on sturdy metal base and meridian or durable plastic base and meridian. • Assembled in the UK with recycled and recyclable materials, using traditional methods • Supplied with information booklet

This useful unit includes four low voltage lamp holders connected in parallel and mounted on BES type base. Individual switches control each lamp, allowing all, some, or none of the lamps to be lit. Four colour-coded 4 mm sockets can be used to link multiple sets together or to connect a power supply and Voltage and Current sensors or meters. Unit comprises: 4 On/Off toggle switches;4 x 4 mm sockets; 4 lamp holders supplied without bulbs, which are available separately. Suggested uses: • Use hand powered generator (EN98100) to feel the increase in power and energy needed to successively light more lamps. • Use with a battery or power supply to study the relationship between voltage, current and resistance. • Useful for studying power, efficiency, and Ohm's law in simple circuit. • Simple to use and quick to set up, as individual components do not need to be connected together to make circuit.
