Heavy, Light & Balance!
Chapter 14: Measurement — Weight
Weight is something we feel before we measure! A big balloon is light. A small stone can be heavy. Let's learn to compare and measure weight!
The Surprising Box!
Riya is packing for a trip. She sees two boxes. 📦
"This big box looks heavy!" she says.
But when she lifts it... "It's so light!" It's full of pillows! 🪶
Then she tries the small box... "Wow, this is heavy!" It's full of books! 📚
Milo tilts his head. "Size doesn't tell you weight!"
Look at these two objects. Which one feels heavier? Click to choose!
⚠️ Remember: Big doesn't always mean heavy! A big balloon is lighter than a small stone. Always lift to feel!
When we're not sure, a balance scale shows us which is heavier!
🏪 At the shop, the grocer says:
"These potatoes weigh 2 kg"
💡 Remember: We use kilograms (kg) for things we can lift — fruits, vegetables, bags, books. For very heavy things like cars, we use tonnes!
Guess first! How heavy do you think this is? Then let's measure!
How heavy is the school bag?
Now we can compare using numbers! Which is heavier?
Which is heavier: the bag (5 kg) or the watermelon (3 kg)?
💡 Tip: The bigger number means heavier! 5 kg is heavier than 3 kg because 5 > 3.
Different situations need different tools! Which tool is best?
