CHANGE OF STATE OF MATTER
Overview
In the previous lesson, we learnt about the properties of a solid, liquid and gas matter/ material. in this lesson you will learn how some materials can be changed from a solid, liquid and gas by heating or cooling the material.
Grade 4 NS & Tech Change of state of matter lesson
Lesson description
In this lesson, students will learn about the three main states of matter: solid, liquid, and gas. They will learn about how matter can change between these states and how this relates to particle theory.
What is a change of state?
Explanation;
Start the lesson by watching the video with the learnerson how to change state of matter. Explain to learners how matter can change state by heating or cooling (pause and explain and discuss each change of state). Allow learners to take the online quiz to so that they can check themselves whether they understood the concepts learnt so far and clarify any misunderstanding. It is important to take the quiz first before sharing it with learners, so that you can explain how to take the quiz and any other concepts that are not mentioned in the video.
Most materials or matter can change from one form to another form. This is called a change of state. The states of matter are solid, liquid and gas. A change of state happens when a liquid such as water to a solid such as ice, or when a gas such as water vapour changes to a liquid such a water. You can change a state of materials by heating or cooling the solid, liquid or gas.
Practical demonstration
Below is a powerpoint presentation of how to carry out the experiment of changing a solid to liquid and gas.
After watching this presentation, complete the online worksheet given about the changes of states and submit for marking and feedback.online worksheet
