Heavy and Light: Comparing Weights in Everyday Life
Weight tells us how heavy or light an object feels when we try to lift it. Some big objects can be light, and some small objects can be heavy!
Heavy Watermelon (Down)
Light Apple (Up)
Measurement of Weight: The heavier side tilts down on a balance beam.
1. What is Heavy vs Light?
• Heavy: Needs a lot of strength to lift (e.g., an iron dumbbell, a car, an elephant).
• Light: Easy to lift with two fingers (e.g., a balloon, a feather, a leaf).
Size Surprise: A huge inflated beach ball is very LIGHT, while a small metal padlock is HEAVY! Size alone does not determine weight.
2. Ordering by Weight
Think about a cricket ball, a balloon, and an apple. From lightest to heaviest:
1. Balloon (lightest)
2. Apple
3. Cricket ball (heaviest)
Words to Know: Heavier, lighter, heaviest, lightest.
💡 Key Learning Takeaways
- Weight describes how heavy or light an object is.
- Big things are not always heavy (e.g., beach ball).
- Small dense things can be surprisingly heavy (e.g., stone, coin).
🎯 Key Learning Takeaways
Heavy vs light concepts.
