Matter and Particles

The video tutorial explains that matter is composed of tiny particles, which are not visible to the naked eye. Through a series of activities, students explore this concept by inflating a balloon to observe air particles, dissolving sugar in water to see how particles interact, and evaporating salt water to understand the persistence of particles. These activities help demonstrate the particle nature of matter.

What did you observe as you blew up the balloon?

What evidence is there that particles of air filled the balloon?

Where did the particles go after adding sugar to the warm water?

What changed in the container over several days?

How does this demonstration illustrate that salt water is made-up of tiny particles?
