Uma loves to do experiments... so her friends surprised her with an experiment kit where she has to build... Electrical Circuits Before Uma starts, she reads the instructions because she knows electricity can be dangerous! And the same applies to you at home: electricity is very dangerous. Experiments with electricity can only be done with kits like Uma's. If you want to do something with electricity, always ask your parents first! In Uma's experiment kit, there are two pieces of wire... with crocodile clips on each end... the light bulb ... and a battery. She wants to try to light up the lightbulb. First, Uma looks at the battery. The battery has a postive terminal with a PLUS symbol... and a negative terminal with a MINUS symbol. If Uma clamps one of the wires to the positive terminal pole... and the other end... goes to the lightbulb... what do you think will happen next? (...) Absolutely nothing! How unusual... what would Uma have to change to make the lamp light up? (...) Uma should take the second wire and clamp it to the negative terminal pole. Where should the other end of the wire go? (...) Uma can attach it to the other connection of the light bulb! Do you think the lamp will shine this time? (...) Indeed! But why? Uma built an electrical circuit, which is a complete path around which electricity can flow. We can also draw it! First, represent the lightbulb, using a circle with an
