3 2 Sam attached a small magnet to the model cat. The magnet was attracted to the fridge door. a) What metal are magnets made from? b) Sam made another model, B. He attached a small magnet to model B. Sam placed model A next to model B. The magnets attracted each other. Label the poles on the magnet on model B. Use the letters N and S. c) Sam then turned the magnet on model A around. What would happen to model B P a g e 1 0

4 3 Jane and Jake had four magnets. They brought them one by one to a box of pins. They counted the number of pins the magnet had attracted and recorded the results. Magnet W X Y Z Number of pins attracted a) Pupils made the following conclusion. Cirlce the correct statement. Jane: Bigger magnets are stronger than the smaller magnets. Jake: Strength of a magnet does not necessarily depend on the size of the magnets b) Which magnet is the strongest magnet? c) Write down the factor Jane and Jake had to keep the same while planning the test Eric is using a band catapult to make a toy car move across the floor. a) What do you think will happen if the catapult is pulled back further? b) Which factor will Eric keep the same to make the test fair?

The magnets show how many paper clips they can hold. a) Are all the magnets of the same strength? b) Which magnet M1 or M2 are strongest? c) If we are testing the strength of magnet do all paperclips have to be of the same size? Why? d) Which of the three magnets are the strongest? A truck carrying a ball in back hit a curb. What would happen to the ball? Circle the picture that shows the correct answer. 5 P a g e 1 0
