This kit and its finished products contain small parts which may cause choking hazard. Keep away from children under 3 years old Please ask an adult for help when getting any material (i.e. potatoes fruits, juice, etc) needed for the experiments 6. Food or beverages used in these experiments are not edible. Please dispose of them immediately after use 7. Do not connect any of the parts provided to any AC wall socket or any batteries. This may cause electric shock or a short circuit. B. CONTENTS 4 zinc plates(silvery grey), 4 copper plates(brownish), 4 connection wires, 2 plastic cups, 1 paper cup, 2 specially designed bottle screw caps, 1 light tower with LED lamp, 1 sound chip, 1 LCD watch moment with protective cover,1 set transparent adhesive tapes, 1 set experiment instruction guide with experiment record sheet and fun facts C. HOW DOES YOUR ENVIRO BATTERY WORK? Your enviro battery works by immersing a pair(or pairs) of connected zinc and copper plates into an aqueous medium such as a potato, mud, water, or a piece of fruit. the zinc plate is the negative electrode; the copper plate is the positive electrode. When the metals are immersed into the electrolyte a chemical reaction takes place. The acid in the electrolyte breaks down the atomic structure of the copper and zinc, causing individual electrons to be released. Zinc is a more reactive metal than copper in this chen process. It generates electrons faster than copper in this chemical process. The excess electrons flow from the zinc plate to the copper plate. This flow of the electrons from a reactive metal to a less reactive metal forms a small current which is strong enough to power a small light bulb, a small watch or a sound chip.

Low Temperature Difference Hot Air St... $81.99 $127.99
Description: Name: Low Temperature Hot Air Engine Model  Size (Dia*H): φ89*135mm Material: Metal Aluminum Surface Treatment: Anodic Oxidation Product Weight: 152g Features: 1. . This low temperature stirling engine, runs on a hot cup of water (Do not put it above a candle or other fire), could be a great conversation starter at work and unique gift to families or friends or for class demonstrations. 2. It is almost ready to run: after the installation, put it on a cup of hot water or Ice water, wait about 20 seconds, gently flip the wheel,then it will run itself. 3. Basically you can run this engine up to 20 minutes with a cup of warm water (the engine must be cool). The bigger the temperature difference between the top and bottom plates the higher RPM you will get. This works best with a hot cup of water underneath and an ice cube in a plastic bag on the top (there is plenty of room for one ice cube on top). 4. Durable, well made, sytlish, and adjustable.Very fantastic craftsmanship, made with Metal Alloy. 5. If there is a little noisy, ONLY use a little graphite dry lube or a pencil quieted it down nicely. Do not use oil to lubricate,which will mix with dust in the air, and become a oil-dirt, finally make the friction to be even bigger.The stirling engine can't run smoothy. Principle: This low temperature stirling engine,runs on a hot cup of water (Do not put it above a candle or other fire). The engine's speed depends entirely upon the temperature difference between the hot side and the cold side. In the case of using a cup of hot beverage, not only is the engine transferring the beverage's heat to the surrounding air, there are air currents constantly crossing the top (cold) plate. The differing temperatures will cause the engine to slow or speed according to the net difference between the two plates. For some extra fun, you could obtain a USB-powered cup warmer and place engine on that. After the warmer finally made it to full temperature, the engine will chug along like a champ.  Package Included: 1 x Low Temperature Engine Model

Description: It is an experimental facility for children to experiment and learn the Physics, it can slide resistance. Item: Slide Rheostat Size: about 16cm Usage: 1. When the current in the circuit is used to adjust the intensity , it should slide rheostat in series with the circuit, and the first raised to the maximum slip resistance rheostat , connect the power supply , then slide the conductive brush , gradually reducing resistance , so that the current strength suitable amount is gradually increased . 2. When used to adjust the voltage of the circuit between two points , and the circuit should varistor connected in parallel , and the first rheostat resistance to minimum , connect the power supply , then slide the conductive brush , and gradually increase the resistance , the circuit ends voltage is gradually increased to the appropriate value. Note: 1. when the rheostat use should not be too close to the heat source. 2. rheostat long-term use may cause poor contact oxidation insulation in contact with the resistance wire brush , then wipe away the oxide layer must be used. Long love vibration and other reasons, it may appear screw loose, loose slider and other illnesses , pay attention to check eliminated. 3. rheostat should not exceed the rated maximum load. Package Included: 1x Slide Rheostat 1x Manual

SHUNMA 31009 Four-stroke Metal Diesel... $178.99 $277.99
SHUNMA 31009 Four-stroke Metal Diesel Internal Combustion Engine Teaching Instrument Physics Experiment Model Description: Brand Name: SHUNMA Item Name: Diesel Engine Model Model: 31009 Weight: 1000g Size: 18.5*12.5*31 cm Material: Metal, Environmentally Friendly Plastic Use for: It is used for the teaching demonstration of the heat engine part in the physics class of the secondary school. The design of this instrument has been extensively solicited opinions from relevant departments, and several improvements have been made to the original model, so as to not only clearly explain the basic working principle of the four-stroke single-cylinder diesel engine, but also be closer to the actual product, and better clarify the common single-cylinder The main structure of the diesel engine to improve the use effect of the instrument. Structure: The front of the instrument is a section cut along the longitudinal axis of the cylinder, the cylindrical cavity in the middle is the cylinder, and the light-colored part next to the cylinder represents the section of the cooling water jackets. The piston moves up and down in the cylinder. The lines on the piston indicate the piston ring and the oil cup. The square cavity under the cylinder is the crankcase. The front of the cylinder is the crankshaft, which is connected to the piston through a connecting rod. . The rear one is a camshaft with two cams in different positions, which push the push rod to move up and down in sequences, and control the opening and closing of the intake valve and exhaust valve at the top of the cylinder through the rocker arm. The middle of the top of the cylinder is the fuel injector. . On the left side of the instrument is a flywheel, and on the right there are models of crankshaft timing gear, camshaft timing gear, oil pump cam and high pressure oil pump. The compression ratio of diesel engines is generally 12-20, so when the piston rises to the top dead center, a certain gap is left proportional to the top of the cylinder. This instrument is equipped with a light display device, and the power supply adopts a AA dry battery or a low-voltage power supply. When the instrument is running, the lights will flash sequentially, which can more intuitively explain the actions of intake and exhaust and fuel injection. There is a handle on the flywheel, which is only used for driving the flywheel to rotate during the demonstration. How to wrok: Turn on the power, adjust the piston to the top dead center, and then slowly turn the flywheel in the direction of the arrow shown on the flywheel, respectively explain the actions of the piston, intake valve, exhaust valve, fuel injection, etc. in the four-stroke cycle, and explain the diesel time The basic working principle of oil machine. The flashing electric ball on the top of the cylinder indicates fuel injection. The fuel supply advance angle of this instrument is 20 degrees, so fuel injection is performed when the compression stroke is not completely finished. Package Included: 1 x Diesel Engine Model
