Causal diagram

A causal diagram is like a picture or a map that shows us how things are connected to each other. It helps us understand why things happen the way they do.

Imagine you want to figure out why your plant is dying. You know that plants need sunlight, water, and nutrients to grow. A causal diagram can show you how these things are related to each other.

Let's draw a picture of a causal diagram!

First, draw a box that represents your plant in the middle of the page. Then, draw three arrows pointing towards the box. These arrows represent sunlight, water, and nutrients.

Now, draw two more arrows coming out of the box. One arrow should point to a sad face, and the other should point to a happy face.

The sad face represents an effect, which is something that happens as a result of the plant not getting what it needs. The happy face represents a positive effect that happens when the plant is healthy.

So, the causal diagram shows that the plant needs sunlight, water, and nutrients to be healthy. If it doesn't get those things, it will start to die (represented by the sad face). If it does get what it needs, it will grow strong and healthy (represented by the happy face).

Causal diagrams can help us understand all kinds of things, from why people get sick to why companies succeed or fail. They are like roadmaps that guide us towards understanding the world around us.
