Description
Learn how batteries work, discover the magic of chemistry and have fun with a unique STEM experiment that combines knowledge and play. An exciting set that cultivates curiosity and shows that science can be simple, creative and fun!
HOW IT WORKS: A typical battery, such as an alkaline battery, has three main parts: an anode (usually zinc), a cathode (often manganese dioxide), and an electrolyte (such as potassium hydroxide). When you plug it into a device, such as a toy motor, a chemical reaction occurs. The anode releases tiny particles called electrons, which travel to the cathode, creating electricity to power the motor! In your homemade battery, the aluminum foil acts as the anode and the lead graphite acts as the cathode. When mixed with salt water, as the electrolyte, and plugged into an LCD watch, the aluminum releases
electrons that flow to the graphite, powering the watch. It produces a small current, enough for the watch but not strong enough for a motor. It’s science magic!
