Working Model of Science for Class 8

The CBSE Science projects below have been tried and tested and are considered among the most popular school exhibition options. Moreover, the materials required to construct these models are common in most households, while others can be purchased cheaply.

These Science Exhibition Working Models Ideas For Class 8 are not only simple to make but also serve a practical purpose. They are suitable for various students, from kids participating in Science fairs to middle school and upper school students.

By utilizing these working models, students can better understand scientific concepts and principles and develop valuable problem-solving and critical-thinking skills. Moreover, these projects can be a great way to engage with Science practically and make it more accessible and interesting for students.

List of Science Working Models for Class 8: Find the Best Experiments

As we have mentioned before, the working model of science for Class 8 easy projects is incredibly interesting and simple to make. All you need is some things, and you can start the process. These projects can also be made at home and as a part of group sessions.

Project for Solar Energy 

This scientific model demonstrates how a concave mirror gathers solar radiation and focuses it into a single, small point. Additionally, it explores how colours can absorb sunlight and influence the amount of heat absorbed by an object. To undertake this project, suitable for CBSE Class 8 Science, one must conduct it outdoors on a sunny day or indoors where sunlight enters the room through a window.

Materials Needed: Wooden stand, a tube, concave mirror, black paper, thermometer

• To conduct this experiment, the first step is to mount the wooden stand in a suitable location. Once the stand is secure, roll pieces of black paper around the tube. 

• Next, attach the tube to the concave or converging mirror. 

• After securing the tube, fill it with tap water, being careful not to spill any of the water. 

• Allow the tube to sit in the sunlight for 30 minutes. After this time has elapsed, use a thermometer to record the water temperature in the tube.

Electric Generator Project

As taught in CBSE Class 8 Science, the electric generator working model aims to give students a basic understanding of how electricity is generated. This hands-on project is designed to be easily created with commonly available materials found in most homes.

The electric generator, also called a wooden generator, is a relatively simple and enjoyable experiment that demonstrates electricity production through the conversion of mechanical energy. The project involves the construction of a simple device that utilizes the principles of electromagnetic induction to produce electricity.

By building this electric generator, students will gain a practical understanding of how electrical energy can be generated from mechanical energy. They will learn about the basic components of an electric generator, such as a magnet, a coil of wire, and a simple rotor. Additionally, they will learn about the relationship between magnetism and electricity and how these two phenomena are closely interrelated.

Project Potato Battery

This is another working model of Science for Class 8 project. Potatoes are known to have high water content and are also rich in various chemical substances. A chemical reaction occurs when these chemicals come into contact with one or more electrodes.

Materials Needed: Two fresh potatoes, copper and zinc electrode, alligator clips, digital clock.

• To perform this experiment, you must insert a zinc and a copper electrode into a potato. 

• Next, you will use alligator clips to connect the electrodes to a digital clock.

• As the electrodes are inserted into the potato, a chemical reaction will occur between the potato's juices and the electrodes. 

• This reaction will generate a small amount of electricity, flowing through the wires and activating the digital clock.
