How do you make a working model on biotechnology?

To make a working model on biotechnology, you can choose a specific aspect of biotechnology such as genetic engineering or fermentation, then design a model that demonstrates the process in a simple and visual way. Use materials like clay, paper, or building blocks to represent the biological components involved, and include labels or diagrams to explain each step of the process. You can also incorporate interactive elements like moving parts or lights to make the model engaging and educational.
