What is reactivity?

Reactivity is when something changes because another thing changed, it’s like a chain reaction you can see and feel.

Imagine you have a toy car that rolls down a ramp. If you make the ramp steeper, the car goes faster. That’s reactivity in action, one change (the steeper ramp) makes another change happen (the faster car).

How It Works

Think of reactivity like a seesaw at the park. When one side goes up, the other side goes down. If you push the left side, the right side moves because of it. That’s reactivity, one part reacting to what happens on the other side.

A Real Example

Imagine you have a bag of marbles and a small bucket. If you pour all the marbles into the bucket, the bucket gets heavier. Now imagine that bucket is attached to a string, and when it gets heavy enough, it pulls up a flag. That’s reactivity, one thing (the marbles) changing causes another thing (the flag) to change too.

Reactivity is everywhere, from your toy car to the seesaw and even the bucket with marbles, just like how you feel things around you change when something else changes. Reactivity is when something changes because another thing changed, it’s like a chain reaction you can see and feel.

Examples

  1. A matchstick catches fire when you strike it, that's reactivity in action!
  2. Baking soda and vinegar make a fizzing volcano, simple reactivity!
  3. When you mix paint colors, they create new colors through reactivity.
