Activity Introduction

water-dripping-tap-heroQuick 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.

Learning goals:

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

Australian Curriculum content description:

Year 7 Mathematics:

  • Identify and investigate issues involving numerical data collected from primary and secondary sources (ACMSP169)

Year 7 Science:

  • Water is an important resource that cycles through the environment (ACSSU222)
  • Science understanding influences the development of practices in areas of human activity such as industry, agriculture and marine and terrestrial resource management (ACSHE121)
  • Identify questions and problems that can be investigated scientifically and make predictions based on scientific knowledge (ACSIS124)
  • Collaboratively and individually plan and conduct a range of investigation types, including fieldwork and experiments, ensuring safety and ethical guidelines are followed (ACSIS125)
  • In fair tests, measure and control variables, and select equipment to collect data with accuracy appropriate to the task (ACSIS126)
  • Summarise data, from students’ own investigations and secondary sources, and use scientific understanding to identify relationships and draw conclusions (ACSIS130)
  • Communicate ideas, findings and solutions to problems using scientific language and representations using digital technologies as appropriate (ACSIS133)

Year 8 Mathematics:

  • Investigate techniques for collecting data, including census, sampling and observation (ACMSP284)

Overarching learning goal: Students investigate the water wastage at their school and analysis their primary data. They take action to reduce the amount of wasted water in their school.

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 freshwater 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 shower uses around 43, 800 litres of water each year. All of this water just ends up down the drain.

What can students do to save water? 

  • Keep a timer in the shower
  • Reducing your shower to 3 m

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.
