Models
Models represent the phenomena that we see in the real world. We are often unable to observe things directly to understand these phenomena. By using models, we can represent processes in organisms and in matter to understand and explain them better. Also, using models allows us to make predictions about these processes.
We can use the railway model to represent the structure of a complex railway system. Similarly, we can use the atomic model to represent the structure of the basic building blocks of matter.
We can use the railway model to explain how the components of a railway system work together to transport people and cargoes. Similarly, we can use a cell model to explain how parts of a cell work together to keep an organism alive.
We can also use the railway model to predict what happens when the rail trucks are blocked. Likewise, we can use the ray model of light to predict what happens when the path of light is blocked.
In the theme, we will learn to use models to study cells, matter and light.
