1. Read the following, then answer the questions:

1- My favourite subject is science. I have three science lessons a week at school. Yesterday, our teacher of science took us to the science lab. We did some experiments about things that float and those which sink. If you put an orange into water, it floats. 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.

a. Answer the following questions:

1. Where did students do some experiments?

2. How many lessons do you have a week?

b. Choose the correct answer from a , b , c or d:

3. The orange peel has …………………….. in it.
