4. activity 2.1 : solid, liquid and gas.
The purpose of learning
• Try to check the alignment, the distance between
the particles and the binding forces. And the
movement of particles in a solid, liquid and gas
using the particle model of arrangement of the
material.
• Explain the different state of substance. The
model is used to sort the particles of substance.

5. activity 2.1 : solid, liquid and gas.

• Ammonia solution 1-2 drops
• Plastic bottles of 250 cm3 1 piece
• Rubber tube connected to 1 set
a gas pipe off

Part 1
Blow the foam tablets softy. When they swaying
but they stick together. When blow heavier, it swaying
again then move around in the button. And blow it is
the heaviest the foam tablets will spread out quickly
around the plastic bottle.

Part 2
When put Potassium permanganate
crystals into the water it turn to be
violet. And smell it quickly.
