Capacity!
Chapter 15: Full, Empty & Holds More
Capacity is about space inside, not size outside. A tall glass might hold less than a wide cup! Let's learn which containers hold more.
Which Holds More?
Riya has a tall glass and a wide cup.
"The tall one must hold more!" she thinks.
But when she pours water, the wide cup overflows first!
Milo barks: "Height isn't everything! Capacity is about space inside!"
Look at each container. Is it full, empty, or half-full?
Watch what happens when we pour from one container to another!
We use litres to measure how much a container can hold. Tap each item to learn more!
The litre is how we measure liquids like water, milk, and juice.
A milk packet from the shop is usually 1 litre! 🥛
💧 Remember: We write litre as L. So "2 litres" becomes "2 L".
How many litres does each container hold? Guess first, then check!

Questions & Answers
How much it holds
What is capacity?
Capacity is how much a container can hold. A bottle, a mug and a bucket all have different capacities.
Is capacity the same as size?
Not always. A tall thin glass can hold less than a short wide one. You have to fill them to be sure.
What units measure capacity?
Millilitres for small amounts and litres for larger ones. One litre is a thousand millilitres.
How do I compare two containers?
Fill one with water and pour it into the other. If it overflows, the first holds more. If space is left, it holds less.
What does full mean?
Full means the container cannot hold any more. Empty means it holds nothing at all.
Why do we pour to compare?
Because your eyes can be fooled by shape. Pouring gives a fair answer every time.
Where do I see litres in daily life?
Milk packets, water bottles, petrol, cold drinks and cooking oil. Look at the label and read the number.
How can I practise at home?
Use cups and bottles at the sink. Guess how many cups fill a bottle, then pour and count. Guess first, then check.
💧 Readiness signs: Child understands that shape affects capacity, compares by pouring rather than guessing by height, uses "litre" correctly in conversation, and can estimate whether a container holds more or less than 1 litre.
