  1. Battery Computer Assignment Take notes to help you write a summary that explains how a dry cell makes electricity. Draw and label a diagram to help explain it. Word Bank: electrolyte, electrodes, chemical reaction, positive, negative, terminals, current electricity

  2. How it Works

  3. You could view a battery as a kind of pump. But instead of pumping water through pipes, the battery moves electrons through a wire and through the things that the wire is connected to.

  4. Here's how a dry cell works: The cell is made up of a zinc can, which acts as the container.

  5. Here's how a dry cell works: The cell is made up of a zinc can, which acts as the container. The other electrode is a carbon rod in the center.

  6. Here's how a dry cell works: The carbon rod is surrounded by a pasty mixture that could be a strong base such as potassium hydroxide. Strong acids like sulfuric acid can also react with certain metals to make electricity.

  7. A chemical reaction from the paste causes the zinc container to steal electrons from the carbon atoms. The carbon atoms become positive while the zinc atoms become negative.

  8. If a circuit is created between the positive and negative terminals of our cell, the electrons will be pulled by the positive carbon atoms. The electrons are pushed by the chemical reaction until the metals are too corroded and the cell is said to be “dead”.

  9. HOMEWORK Now use your notes to write a paragraph that explains how a dry cell makes electricity. Draw and label a diagram to help explain it. Word Bank: electrolyte, electrodes, chemical reaction, positive, negative, terminals, current electricity
