# Bottles (1)

For this activity which explores capacity, you will need to collect some bottles and jars.

You need to find a collection of jars and bottles of different sizes and shapes, like those in the picture below:

I wonder which holds the most/least liquid?

Use estimation first of all.

How could you find out? Explore!

Can you find a way of counting how many "small container-fulls" each will hold?

Can you find a better way?

Have a go at this task yourself by collecting some different jars and bottles.

### Why do this problem?

This problem is useful for young pupils to start considering capacity. It will encourage discussion between pupils and between pupil and teacher.### Possible approach

Although some discussion could be had by looking at the bottles pictured here, it would be good for the pupils to have a variety of bottles/jars for them to talk about and to explore the capacities practically.

Teachers could give the pupils a long time to both discuss their opinions of how the capacities compare and then how they could explore the capacities further. When it comes to finding a "small container", give them opportunities to try out the different suggestions they have.
