 * Activities**
 * 1) Read p142 and answer Q1
 * 2) Discuss and look at the demonstration of what makes a circuit a parallel circuit (you can think of a parallel circuit as two, or more circuits, that share a single power source).
 * 3) Investigate [|Parallel circuits] for yourself. Follow the worksheet, copy and complete in your exercise book to record your findings.
 * 4) Complete the [|Electricity questions] use the video and textbook to help you if you get stuck
 * 1) Voltage in series and parallel circuits - discuss what voltage is
 * 2) Write down the definition of voltage in your book
 * 3) Look at the simulations and build your own example circuits
 * 1) Answer Q7 from p143 of Exploring science 7. Use the words 'current' and 'voltage' in your answer.
 * 2) Describe how measuring voltage and current is different (use the words //series// and //parallel// in your answer).
 * 3) Complete [|Another model for current]
 * 4) Extension: Read and about and answer the questions on [|Ring mains]
