Read the passage carefully, and decide whether the sentences are True or False 

Our school has a model club. The members of the club try to make water rockets. The students taking part in the club love discovering new things  and learning science subjects. A water rocket doesn't cost you much. You can use the things you have used such as empty bottles, old types of bicycles. The model has two main parts : the base and the rocket.  The pump in the base is made up of water pipes and it can increase the pressure of water. The rocket made from empty bottles should have blades in its tail and a pointed head. These parts help the water go in the correct path as the membershave planned. When we use the pump to incease the pressure of water, the rocket will take off and fly into the air. our school club has just won the first prize on making water rockets.
