- Step 2: Take two containers and label them 'Organic' and 'Inorganic'.
- Step 3: Place the organic waste in one container and inorganic in the other.
The learning connection
Hands-on experiments engage students, making learning memorable. Observing changes in real time helps solidify concepts of decomposition and sustainability.
Try it with your learner
1. Layer soil in the bottom of the container. 2. Add organic waste on one side and inorganic waste on the other. 3. Pour 100 ml of water evenly over the waste. 4. Cover the container loosely to allow airflow. 5. Place the container in a warm, sunny spot. 6. Check the container weekly and note any changes you observe.
