 1. Water Filtration System

This is a classic and very practical science project for Class 8 working model that helps students understand the science behind water purification. In this project, you can build a simple water filtration system using household items like sand, gravel, and cotton.

Materials Needed:

• A plastic bottle,
• Sand,
• Gravel,
• Cotton,
• Activated charcoal (optional).

Steps:

1. Cut the bottom of the plastic bottle and place it upside down.
2. Layer the cotton at the neck of the bottle.
3. Add a layer of activated charcoal (optional), followed by sand and then gravel.
4. Pour dirty water through the top and collect the clean water at the bottom.

Explanation: This model mimics how natural water filtration occurs, with the different layers trapping various impurities. It can be a great working model that shows the importance of clean water and how filtration works in water treatment plants.

Materials Needed:

• Battery,
• Wires,
• Bulb,
• Switch.

Steps:

1. Connect the wires to the battery terminals and attach them to the bulb and switch.
2. Complete the circuit by flipping the switch to light the bulb.
3. For a more advanced model, try adding multiple bulbs to create a series or parallel circuit.

Explanation: This project helps students understand the flow of electric current, the difference between series and parallel circuits, and how electrical energy is converted into light.
