Science Tuition Class Practical Hands-on: Do you need a Potato for a Potato Battery?

Chemistry, Science, Tuition
What better way to ingrain in our Science students the application of Science in actual hands-on work! The potato battery has been used in school experiments for a long time. While commercial kits are available, we decide to get our hands wet and dirty to make one from raw materials and bits and pieces of electrical apparatus as described a previous post. Today, we revisit the potato battery and attempt to make one out of fruit/vegetable other than a potato. Theory of Our Battery For a good discussion of how a potato battery works, refer to our previous post which mentioned the Reactivity Series or Electrochemical Series. It also talked about the potato acting as an electrolyte to conduct an electric current within the battery. For this experiment during our…

Our Enrichment Programmes are designed for students to be away from their studies and learn new knowledge and skills, both academic and non-academic. They are open to both our centre’s regular students and any other students of the right academic level. The following programmes are scheduled to run on the given dates. Click on each of them for fees and further information. Call or WhatsApp us at 8768 6497 or Email us at info@imatter.com.sg to register.

While commercial kits are available, we decide to get our hands wet and dirty to make one from raw materials and bits and pieces of electrical apparatus. Common Misconception Most students (and some adults) believe that the energy of a Potato Battery comes from the potato. But no. Its energy comes from the 2 different metals inserted into the Potato Battery. They differ in their reactivity according to the Reactivity Series or Electrochemical Series - a concept which is only covered in Upper Secondary Chemistry. In our hands-on experiment, we at first tried a copper strip and a screw. The…
