Lesson Plan version 1.1 activities
1.Collect information about soil erosion and make notes on the causes of soil erosion and ways of preventing it. Exchange the information with your friends.
2. You can make compost in a small place around your house or school or even in a bucket or a plastic bag. Dig a pit. Put any organic waste such as vegetable peels, cow dung, fallen leaves from trees, crop residues or even weeds into the pit. Cut them into small pieces if they are too large. Put a layer of soil over them. Sprinkle water over the soil to keep the matter moist. Go on heaping layer after layer until the pit or the bag is full. Microbes break up the organic matter into simpler forms. Adding a few earthworms will also help. Leave it for 8-10 weeks. Compost is now ready for use
3. Collect more information about the types of irrigation systems and crops grown adopting these systems.
