ClassX Video Lessons Youtube Channel Next Generation Science Measuring and Comparing Masses Using a Simple Balance
Today, we’re going to have fun learning about something called a balance. A balance is a tool that helps us see which things are heavier or lighter. Let’s use toy blocks to learn how it works!
Mass is a big word that means how heavy something is. We can use blocks to help us understand mass. Each block is like one unit of mass. That means one block is one unit heavy!
Let’s play a game with our balance! If we put one block on one side and one block on the other side, the balance stays even. This means both blocks are the same mass!
Now, let’s try something different. If we put two blocks on one side and one block on the other side, the side with two blocks goes down. This shows us that two blocks are heavier than one block.
Let’s try again! If we put two blocks on one side and four blocks on the other side, the side with four blocks goes down. That means four blocks are heavier than two blocks!
Isn’t it fun to see how a balance works? You can try this at home with your toys. See which toys are heavier or lighter. Remember, more blocks mean more mass!
Keep learning and exploring, and you’ll discover lots of exciting things!
Balance Challenge: Create your own balance at home using a coat hanger and some string. Hang the coat hanger on a doorknob or a hook. Use small cups or bags tied to each end of the hanger as the balance pans. Gather different small toys or objects from around your house. Predict which items are heavier and which are lighter. Place them in the cups and see if your predictions were correct. Talk about why some items are heavier than others.
Mass Hunt: Go on a “mass hunt” around your classroom or home. Find objects that you think have the same mass as one block, two blocks, or even more. Use your balance to test your guesses. Can you find something that is exactly the same mass as three blocks? How about five blocks? Share your findings with a friend or family member.
Story Time with Mass: Create a short story about a character who uses a balance to solve a problem. Maybe they need to figure out which fruit is heavier to make a fruit salad, or they need to balance their toys to build a tower. Draw pictures to go along with your story and share it with the class. What did your character learn about mass and balance?

In this segment, we will compare mass using a balance. Let’s explore how we can use a balance to compare the masses of toy blocks.
One block represents one unit of mass. When we place one block on one side of the balance and another block on the opposite side, we can observe that the masses of each block are equal.
Now, if we place two blocks on one side of the balance and one block on the other side, we can see that two blocks have a greater mass than one block.
Next, let’s place two blocks on one side of the balance and four blocks on the other side. In this case, four blocks have a greater mass than two blocks.
