Making Charcoal in Chad, Africa

11. Making Charcoal in Chad, Africa Charcoal is the most popular type of fuel in Chad, and is seen as more modern than dry firewood. It burns for longer than wood, so it is cheaper to use, and it produces less smoke. It is especially popular in big towns. Unfortunately, charcoal is less efficient, so more trees must be cut down.

12. PICTURE REVEAL Once you’ve read this, you can delete this slide. All you need to do is: Open the presentation (you’ve done that already) Go to VIEW, MASTER, SLIDE MASTER Right click on the MASTER SLIDE. Choose BACKGROUND, FILL EFFECTS, PICTURE and browse to the picture of your choice. Set this as the backgound on the master slides and all other slides will now have this picture hidden by the boxes. Ask pupils to choose a number and this will reveal one square. They have 5 seconds to look and guess, then click HOME. They need to keep in mind what they’ve seen as they only get one section of the picture at a time. Once someone gets the correct answer, click home then click on the INFORMATION action button to reveal the actual picture. Students could also be asked to talk about the section they see, or name 3 things they can identify etc… So by changing the picture on the MASTER SLIDE you can create as many of these as you like.
