Answer:
Connect up the circuits in the diagrams. Use the results to answer the questions.

 Which circuit has the brighter globe? Why do you think this occurs?

Which circuit has the brighter globe(s)? Why do you think they are brighter?

Which circuit has the brighter globes? Why do you think this happens?

How do you think the amount of electricity flowing in a circuit is affected by the number of batteries (see Question 2) and by the number of globes (see Question 3)? You could connect an ammeter (which measures current) in the circuit to check your ideas.
How is the speed of an electric motor affected by the number of batteries in the circuit?

Try these two circuits. If you wanted to light up two globes as brightly as possible using one battery, which is the better way to do it?

  Predict which of each pair of circuits in the diagram will have the brighter globes. Construct these circuits and find out if your predictions were correct.
