Clean Up Australia - Leaky Tap Experiment: Year 7 & 8

Activity Introduction

Quick summary: Students will learn about water wastage and understand the importance of saving water. They will undertake a measuring task to see how much water leaks from a tap. Students will look at how water is wasted around the school and home and what actions they can undertake to conserve more water.

Following this lesson plan is an ideal way for your school to take part in Schools Clean Up Day or a Clean Up on any day of the year. You’ll be joining thousands of amazing teachers in making a difference and creating positive environmental change.

Learning intentions:

Students investigate the water wastage at their school
Students analyse and evaluate primary data
Students begin to take responsibility for their personal water use.

Teacher content information: Australia is one of the driest continents on Earth, yet we use more water per person than anyone else in the world! Australians use more than 1 million litres of fresh water per person each year. In an average Australian city, this means that the water we use every day in and around our homes would fill the equivalent of 1,000 Olympic swimming pools!

Households use about 44% of their total water inside the home, half of which is used in the shower. Conventional showers use an average 12 litres of water per minute. Therefore, a person who has a daily 10-minute showe

Leaky Tap Experiment

My area is:
Prediction:

1. How many taps are in this area?

2. How many of those taps are leaking?

3. Pick one of your leaking taps or make one drip. Have one member of your group time one minute.

Collect the water that drips from the tap in one minute in a container.
Count the number of drops that fall in a minute.
Remember to turn off the tap!

4. Go back to class and find out how much water you collected in a minute by pouring the container into a measuring jar.

5. Fill out the table with the rest of your class.

Area	Number of taps	Number of leaking taps	How many drops of water per minute?	How much water is dripping in a minute?

Questions:

1. Which tap leaked the most in a day? How much water?
2. Which tap leaked the least in a day? How much water?
3. What
