State of matter
This document describes an activity to teach students about the different states of matter - solid, liquid, and gas - using a particle model. The activity involves using foam tablets, potassium permanganate crystals, and ammonia solution to demonstrate the behavior of particles in each state as they are affected by forces and movement. Safety cautions are provided for working with the chemicals. Students will observe how the foam tablets and potassium permanganate crystals behave when interacted with to draw conclusions about the states of matter.
State of matter
- 1. States of substance Teacher : Miss Thidarat Soyjak The learning area of Science Yasothonpittayakom school
- 2.
- 3. activity 2.1 : solid,liquid and gas.
- 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. Equipments and materials • Foam tablets 80 cm3 • Potassium permanganate crystals 1-2 crystals • Ammonia solution 1-2 drops • Plastic bottles of 250 cm3 1 piece • Rubber tube connected to 1 set a gas pipe off
- 6. activity 2.1 :solid, liquid and gas. Equipment and materials • with a set of plastic bottles 1 set • Beaker 100 cm3 1 piece • Glass bottles 1 piece • Small cotton bale 1 piece • Forceps or a spoon 1 piece • Refined water 100 cm 3
- 7. Cautions and suggestions. •Ammonia solution can be danger to breathing system. Don’t smell it and drop on wool about 1-2 drops. And close it immediately. • Potassium permanganate crystals can be danger to skin system.
- 8. Results 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.
- 9. Results Part 2 When put Potassium permanganate crystals into the water it turn to be violet. And smell it quickly.
