In this lesson, students explore the diverse materials that make up the world around them by sorting objects based on size, color, and texture. They learn the importance of different materials in everyday items, such as the use of hard materials for floors and soft materials for clothing, and are encouraged to engage in hands-on activities by identifying and sorting objects in their own environment. The lesson emphasizes the fun and educational aspects of discovering materials and their properties.
  1. What are some big objects you can find in your classroom?
  2. Can you name three colors of objects you see around you?
  3. How do different materials feel when you touch them?

Discovering the World of Materials

Hello everyone! Did you know that everything around us is made of different materials? Let’s explore how we can describe and organize these materials in fun ways!

Sorting by Size

Imagine you’re in a classroom. You see big objects like scissors, a stapler, and a computer mouse. Then, there are smaller things like a die, an eraser, a paperclip, a pencil, and a half dome. We can sort these objects by size! Big things go in one group, and small things go in another. Isn’t that cool?

Sorting by Color

Now, let’s sort by color! We have red objects like a red stapler, red scissors, and a red die. There are also grey objects like a grey mouse and a grey paperclip. We can’t forget the green die and green eraser, and the yellow pencil and yellow dome. Sorting by color makes everything look so organized!

Sorting by Texture

Next, let’s feel the objects. Some are hard, like the computer mouse, paperclip, die, scissors, and stapler. Others are soft, like the eraser and half dome. The pencil is hard too. Sorting by texture helps us understand how things feel!

Why Materials Matter

Different materials are used for different things. For example, floors are hard so we can walk on them, and clothes are soft to keep us comfy. Imagine if floors were soft and clothes were hard—how silly would that be?

Some materials are strong, like stone. Stone is used to build houses and roads because it’s heavy and solid. But if we made a boat from stone, it would sink! Boats need to be light and float, so we use wood. Wood floats on water, making it perfect for boats!

Exploring Materials Around You

Wood is used for many things like houses, benches, toys, and games. Now it’s your turn! Look around your home or school. Can you find different objects? Try sorting them by color, size, or texture. It’s a fun way to learn about the world!

We’d love to hear about the objects you found and how you sorted them. Share your discoveries with us!

That’s all for today. See you next time! Goodbye!

  • What are some objects you can find at home or in your classroom that you could sort by size, color, or texture? How would you sort them?
  • Can you think of a time when you used something made of a special material, like a wooden toy or a soft blanket? Why do you think that material was chosen for that object?
  • Imagine if you could create a new object using any material you want. What would you make, and what materials would you use? Why?
  1. Material Hunt: Go on a scavenger hunt around your home or classroom. Find five different objects and try to identify what material each one is made of. Are they made of wood, plastic, metal, or something else? Share your findings with a friend or family member and explain why you think each object is made from that material.

  2. Create a Sorting Game: Gather a collection of small objects, such as buttons, coins, or toy blocks. Sort them into groups based on size, color, or texture. Once sorted, mix them up and challenge a friend or family member to sort them again. Discuss why you sorted them the way you did and if there are other ways to sort them.

  3. Imagine and Draw: Think about a world where materials are used differently. What if chairs were made of jelly or shoes were made of paper? Draw a picture of your imagined world and describe how life would be different. Share your drawing with the class and talk about why materials are important for the things we use every day.

Sure! Here’s a sanitized version of the transcript, removing any informal language and ensuring clarity:

Hello everyone! The world around us is composed of various materials, and we can describe these materials in different ways. For example, let’s consider some objects that we might find in a classroom. These objects can be arranged based on their properties.

First, we will arrange them by size. We have several large objects and several smaller objects. We will place our large objects, such as scissors, a stapler, and a computer mouse, over here. Then, we will take our smaller objects, including a die, an eraser, a paperclip, a pencil, and a half dome, and move them over here. This demonstrates how we can separate them based on size.

Next, let’s try arranging them by color. We have red objects, including a red stapler, red scissors, and a red die. We also have a grey mouse and a grey paperclip, a green die and a green eraser, and a yellow pencil and a yellow dome.

We can also arrange these objects based on texture. We have some hard objects and some soft objects. We will place our hard objects over here and our soft objects over here. Our computer mouse and paperclip are both hard objects, as are our die, scissors, and stapler. On the other hand, our eraser and half dome are soft, while the pencil is a hard object.

Different objects are made from different materials for convenience. For example, the floor is hard so that we can stand on it confidently, while our clothes are soft for comfort. Imagine if builders and clothing manufacturers switched those materials; it would be quite a disaster!

If we look around, we notice that all things are made from different materials, each with distinct properties. For instance, stone is hard and solid. Strong structures, such as houses and pavements, can be made from stone because it is heavy and dense. However, if we made a boat from stone, it would sink due to its weight.

Instead, we need materials that are light and can float, like wood. If we place a wooden boat in water, it will float due to its properties, unlike stone. This is why builders have used wood for boat construction for thousands of years. Nowadays, there are even more durable floating materials, such as plastics, but many boats are still made from wood.

Wood is used in various objects, including houses, benches, boats, toys, and games.

Now it’s your turn! Look around your school or home and identify different objects. Try organizing them into groups based on their properties, such as color, size, or shape. Observing these properties will help us better understand the world around us.

Feel free to leave comments below and share the objects you found and how you organized them. We would love to hear from you!

That’s it for today. We’ll see you later. Goodbye!
