Pre-reading question: - Does an orange sink or float in water? 2. Read about the experiment and put the pictures in the ordeer: SB page 7 Does it float or sink?

)1(

)4(

Do this experiment with an orange. ●

Put an orange in some water. What happens?

●

If you put an orange into water, it floats on top of the water.

●

Peel the orange and do the experiment again. Now what happens?

●

If you peel the orange and then put it into the water, the orange sinks to the bottom.

This science experiment tells us that the orange peel has air in it. If something has enough air in it, it doesn’t sink. Now do a similar experiment with oil. Watch what happens. ● When

you add oil to some

water, the oil floats because it is lighter than water.

: W atch this experiment. You need a glass bottle, a balloon and some hot water. First, put the balloon over the top of the bottle. Now, heat the bottle in the water. What happens if the air in the bottle becomes warm? 57

UNIT

11 Hassan : When the air in the bottle becomes warm, the balloon fills up with air! Why does this happen? Ali

: When you heat air, the air moves around faster. This fills up the space in the bottle and pushes the air into the balloon.

Girl 2 : What happens next? Teacher : Finally, you put an egg into the glass of salty water. What happens now? Girl 2 : The egg floats! Teacher : That’s right. Girl 1 : Why does this happen? Teacher : I t happens because usually an egg is heavier than water. That’s why it sinks. But when you add salt to water, the water becomes heavier than the egg. The egg doesn’t sink, it floats. 59
