Pupil’s book page 60 ex 1 (listen and read)
Picture 1
Mr Yusuf: If I put this coin in water, it sinks. But a ruler floats. Why?
Ali: The coin is made of metal, so it sinks. It’s small and heavy.
Kareem: The ruler is made of wood, so it floats. It’s big, but it’s light.
Picture 2
Mr Yusuf: That’s right! Well done, boys. This week, there’s a school science competition. You must do an interesting experiment to find out about objects that sink or float. The prize is this science book.
Ali: Great! I love competitions.
Kareem: Me too.
Picture 3
Laila: What happens if we put an orange in water?
Ali: Look. It floats. But what happens if we peel the orange? Does it still float?
Laila: let’s find out.
Picture 4
Ali: If I put an orange in the water, it floats. But look! If I peel the orange, it sinks.
Mr Yusuf: Why does this happen?
Ali: The orange peel has air in it. This makes the orange float.
