Preparations for Experiments at Home

Experiments at home - is a great way to introduce children to the basics of physics and chemistry, and to facilitate the understanding of complex laws and abstract terms by means of a demonstration. And to carry them out does not need to acquire expensive reagents or special equipment. After all, without hesitation, every day we carry out experiments at home - by adding slaked soda in the batter prior to connecting batteries to the flashlight. Read on to find out how easy, simple and safe to carry out interesting experiments.

Did you know that lemon can be used as batteries? However, very low power. Experiments at home with the children demonstrate citrus battery operation and a closed electrical circuit. You will need 4 lemons - 4 pcs, 4 galvanized nails, 4 small pieces of copper (you can take the coin), 5 crocodile clips to the wires short length (about 20 cm), a small lamp or torch. BTW, you can buy crocodile clips at Banggood. Besides, you can easily get other electronic accessories (e.g. cheap acrylic mirror) there with high quality and reasonable prices.

Here's how to spend experience: Ride on a hard surface, then gently squeeze the lemons that they let the juice inside the skin. Insert one galvanized nails and a single piece of copper in each lemon. Arrange them on a single line. Connect one end of the wire to galvanized nails, and the other - to a piece of copper in another lemon. Repeat this step until all the fruit will not be connected to each other. When you're done, you have to stay one nail 1 and 1 piece of copper, which came to nothing connected. Prepare your lamp, and determine the polarity of the battery. Plug the remaining piece of copper (plus) and a nail (minus) to the plus and minus flashlight. Thus, the chain connected lemons - a battery. Turn on the light bulb, which will operate from the power of fruit! To repeat such experiments in the home is also suitable potatoes, especially green.
