Hi, Primary 5 students! Welcome back to Basic Science and Technology. In our previous lesson, we learned about No previous lesson found.. Today, we’re going to learn about WASTE DISPOSAL.

Objectives

By the end of this lesson, you should be able to:

• Define a compost pit.
• Explain the importance of making a compost pit.

Waste Disposal

Waste disposal is the process of getting rid of unwanted materials. There are different ways to dispose of waste, but one important method is composting.

What is a Compost Pit?

A compost pit is a designated area where organic waste like vegetable peels, leaves, and other biodegradable materials are collected, decomposed, and turned into nutrient-rich compost for gardening and farming. It helps in reducing waste and improving soil fertility.

Making a Compost Pit

Making a compost pit is a simple process that involves the following steps:

1. Choose a suitable location: Select a shaded area in your garden or backyard that receives some sunlight.
2. Dig a pit: Dig a pit about 3 feet wide, 3 feet long, and 2 feet deep.
3. Add layers: Start by adding a layer of twigs or branches at the bottom of the pit for drainage. Then, add layers of organic waste, such as leaves, grass clippings, vegetable peels, and food scraps.
4. Mix and moisten: Mix the layers well and moisten them with water. The ideal moisture level should be like a wrung-out sponge.
5. Cover the pit: Cover the pit with a layer of soil or compost to prevent pests and keep the moisture in.
6. Turn the compost: Turn the compost every few weeks to ensure proper aeration and decomposition.
7. Harvest the compost: After a few months, the compost will be ready to use.
