Teaching ideas for Matter
We hope you have visited our previous blog. This blog contains videos and activities for Matter.
a) Using Videos
The teacher can use this video to introduce the concept to children after asking the big questions.
This video answers the following questions – What is matter? What are the different types of matter along with examples? And is air matter and why? (5,1)(5,2)
This is an excellent way of making the children to connect the topic with their daily life. It will be great if the teacher can think of activities on these lines where the children derive the understanding of the topic from their surroundings.
Activity 1: Make a list of all things around you and group it into solids, liquids, and gas along with the reasons for choosing a certain state. This activity can help children improve their observation skills and compare objects around them.(5,2)
During this activity let the children move around and explore things. Ask them to put down the things into these categories along with the reasons behind it. Push them to come up with as many points as possible.
Activity 2: Chain Activity to understand molecular structure of solids, liquids, and gases – (7,1)(7,2)
This activity can be used in order to explain the difference among the molecular structures of the three states of matter.
1) Ask 5 students to volunteer and bring them in front of the class.
2) First, ask all of them to hold each other by the waist. Tell the class that the 5 students are the molecules of matter. Ask the students to hold each other tightly with no gaps. Bring a new student in the front and ask him/her to move them.
Question: Will it be easy or difficult to move the chain? How is the bond, weak or strong?
ESR: It will be difficult. It is strong.
3) Then explain when the molecules are close and the bond is strong, the matter becomes rigid and strong.
Question: Which type of matter is rigid and strong?
4) Next, ask the same 5 students to hold each other with their hands. Again ask another student to push and change the shape of the group.
Question: Was it easy or difficult to move them?How is the molecular bond?
ESR: It was easy. Weak.
5) Then explain when the molecules are not as close and the bond is less strong, the matter becomes flexible.
Question: Which type of matter is more flexible?
5) Next, ask the same 5 students to hold each other with threads. Again ask another student to push and change the shape of the group.
Question: How difficult was it to move the chain?How is the molecular bond?
ESR: It was very easy. Very Weak.
6) Then explain when the molecules are very far and the bond is very weak, the matter becomes more flexible. Question – Which type of matter is the most flexible? (ESR: gas)
Question: Which type of matter is most flexible?
a) Properties of different states of matter (5,3)(7,1)(7,2)(7,3)
- 3 plastic bags
- one glass of water
1.Put a stone in the first plastic bag and seal it. Ask your students to squeeze and press the bag. What happens? Let them try to bend the stone to change its shape.
Question: Ask them why they cannot bend the stone.
ESR: Stone is a solid and solids are rigid with a fixed shape.
2. Put water in the second plastic bag and then seal it. Tell students to observe the water in the bag carefully. Ask a representative to gently squeeze the bag of water.
Question: Does the shape of water change?
ESR: Yes because water is a liquid. Liquids have no fixed shape and take the shape of the container.
3. Blow air into the third plastic bag and then seal it. Gently press the plastic bag.
Question: Does the shape of the air change? Open the bag to release the air. What happens?
ESR: Cannot be seen. But the plastic bag changes with pressure. When the bag is opened, the air goes away and the plastic is not full this shows air has mass.
The above activity can help you introduce the properties of different states of matter and explain the arrangements of particles for each state. For more information on the activity, click here.
After these activities, the teacher can provide independent reading materials to children given in this article.
