# Maths Investigation / Down the Drain – Introduction

Water is a precious resource, so we all try to be careful when using large amounts of water. We can take shorter showers and avoid watering the gardens in the middle of the day.

But what about the small amounts of water? A tiny constant drip from a tap wastes a surprising amount of water over time.

If you know how much water goes down the drain when you leave the tap running while cleaning your teeth, you might just change your habits.

We are going to investigate ways to find out how much water goes down the drain.

To do this we need to know the metric units of measurements that are used to measure capacity.

Think about what unit of measurement can be used to measure water.

–       What would we use to measure a small bottle of water or medicine cup?

–       What would we use to measure a sink of water, a bath or the amount of water a person drinks in one day?

–       What would we use to measure a large swimming pool?

–       What would we use to measure a large body of water such as the Hazelwood Pondage or Lake Narracan?

Respond to these questions as a comment on the blog.

Wow, Mr Andrews, it looks like you have been working hard on measuring! In my class (56J) we are measuring but we are measuring angles with our protractors. Its hard because you need to get it even on your protractor and strait so you get the right measurement. The little ones on the protractor are hard because you need to count them and they are soooooooo microscopical. I’M SERIOUS. Don’t tell me i’m blind. 😀
