What is Intervention (Experiment)?

An intervention is like when you try something new to see if it makes a change, just like testing out a different snack to see if your friend likes it more.

Imagine you and your friend are playing with blocks. You both build towers, but you use red blocks, and your friend uses blue ones. One day, you decide to switch, you use blue blocks, and your friend uses red ones. Then you see whose tower is taller or if the colors make a difference in how fun it is to play. That’s an intervention, you changed something on purpose to see what happens.

Sometimes, we don’t know which way things will go unless we try something new. Like when your teacher changes the homework or tries a different game during recess. You might not know if it's better until you play with it for a while.

Think of an experiment like a special kind of intervention, it’s when you test out one thing and then compare it to another, just like trying two kinds of ice cream to see which is tastier.
