5 3 Experimenting 1 Form groups of five to do this experiment. Each group will explain in class their conclusions from the experiment. You will need: A spade a container a piece of polythene about cm several medium-sized stones fresh plants from the environment, such as herbs, leaves or branches from shrubs... Procedure: a) Dig a hole in the ground about 30 cm deep and with a diameter of about 60 cm. b) Put the container in the centre of the hole and surround it with fresh plants. c) Cover it all with the polythene, and hold this in place with stones. Put a stone in the centre of the polythene, just above the container. Look at the container 24 hours later. What has happened?

19 10 Listening 68 1 Listen and fill the gaps in the text. Then discuss with your classmates whether biofuels are renewable or non-renewable energies, and the advantages and disadvantages of their use. Biofuels are components obtained from cultivated which produce when they are burnt. One of the crops most used for the of biofuels is maize. The problem is that, biofuels from maize, a large of land is necessary for its, and this cannot be used for production.
