Full and Empty: Understanding Capacity States
Capacity is the maximum amount of liquid (water, milk, juice) that a container can hold.
FULL
HALF-FULL
EMPTY
Measurement of Capacity: Containers can be Full, Half-Full, or Empty.
1. Three States of a Container
• Full: Filled right to the top brim with liquid; cannot hold any more without spilling.
• Half-Full: Filled up to the halfway mark.
• Empty: Has zero liquid inside.
Nearly Full & Nearly Empty: We also use 'nearly full' when almost at the brim, and 'nearly empty' when only a few drops remain at the bottom.
2. Liquids Take the Shape of Containers
If you pour 1 glass of water into a round bowl, it looks wide and shallow. If you pour it into a tall vase, it looks high. But the amount of water is still exactly the same!
Conservation Concept: Don't let tall containers trick you! Always check how much water went in.
💡 Key Learning Takeaways
- Capacity is how much liquid a container holds.
- Full = up to the brim; Empty = no liquid.
- Liquids take the shape of their container.
🎯 Key Learning Takeaways
Full, half-full, and empty.
