# Red Class have the Capacity!

Red Class have been thinking about measuring liquids. We spotted one thing very quickly. You can’t hold liquids in your hands to measure them.

So, we started looking at containers.

Once we started looking, we saw them everywhere…

We spotted that they all had a number in millilitres (ml) written on the labels. We investigated and found that liquids are measured in millilitres. Wow!

We collected some containers in class and decided to order them from smallest to biggest. Most of us thought that the tall, thin container would hold the most liquid.

We experimented to find out if we were right. We counted how many times a 50 millilitre (50ml) container could be used to fill the containers.

Ask us which container had the largest capacity. Clue: It wasn’t the tall thin one! Can you guess which one it was?

Once we started to investigate, we couldn’t stop. We poured, measured and counted to find the capacity of lots of containers.

We are great capacity and measure investigators.
