Comparing containers by how much fits inside.

Today we distinguish water already inside a container from how much it can hold when full.
| Term | What it means |
|---|---|
| Empty | Nothing inside. |
| Capacity | How much fits when full. |
An empty cup has no water. A full cup cannot hold more without spilling. The amount inside can change while the cup stays the same. Capacity means how much fits when the container is full. In identical cups, higher water means more water. In different shapes, height alone can trick us: a wide container may hold more at a lower level.

The cup size stays the same; the water changes.
With adult help, fill one container, then pour all its water into an empty second container. If water remains in the first when the second is full, the first holds more. If the second still has room, it holds more. Use a tray to catch spills; spilled water cannot tell us a fair result.
Test two washable containers with an adult. Predict which holds more, pour carefully, then explain what the remaining space or water shows. Repeat if water spills.
[Full]
Check the outlines.
Identical cups.
Their sizes match.
Compare the water.
Full cup has more.
More of the same space is filled.
An empty jar takes five equal scoops.
1, 2, 3, 4, 5.
Each scoop adds the same amount.
Name its capacity.
Within each pair the cups are identical. Match the pair to the cup containing more water NOW.
