Условие
A. Read the text and find in it “instruction” phrases.
Nothing can burn without oxygen. To find out how much oxygen there is in the air, make a simple experiment. The first thing you should do is to stand a candle in a bowl of water. Light the candle. Be careful not to burn yourself. The next thing you do is to cover the candle with a glass jar. Remember that water should be able to get into the jar. Another thing to remember is to mark the level of water in the jar. As the candle burns, there becomes less oxygen in the air and the water goes up to take its place. Soon the candle goes out − all the oxygen has gone. You will find that the water has gone one fifth of the way up the jar. A fifth of the air is oxygen.
B. Complete the text “Grow Your Own Violets”. Use the “instruction” phrases.
