– understand why someone might collect data about a problem or issue
– collect data and display data
– make a statement about the data we have collected
We have probably all been told that it is important to save water. Today we are going to inquire about our own water usage and compare it with countries that have less access to clean water than us.
Read these instructions carefully
1. To find out how much water you use on average daily, take turns in your group taking the water usage questionnaire. Record the amount in your book (e.g. Daily water usage for the Nathan/Brittain household: 138.54 gallons per day).
2. Divide this amount by the number of people who live in your house to find the average daily water usage per person (e.g. Average daily water usage in the Nathan/Brittain household per person: 46). Record this in your book, also.
3. Visit Water.org and have a look at each of the ‘water facts’ and the info graphics that go with them. In your books, write down two interesting or surprising facts.
4. On a shared piece of paper, each person from your Maths group write down their name and their average daily water usage per person.
5. Using the shared data, in your books create a graph to display the average daily water usage per person for your maths group.
6. A jerry can, like you see in the top photo, carries 5 gallons of water.
– How many jerry cans would it take to gather the amount of water you use per person in your house each day
– How many jerry cans would it take to gather the water you use daily, for your whole house?
– How many jerry cans would it take to gather the water you use daily, for your whole group?
7. On average, women and children in the developing world walk 6km (about 1 and a half hours) to gather water.
– How many kilometres would you have to walk to gather the water you use in your whole house, daily?
– List some ways it would impact your life if you and your mum had to walk to gather the water you use every day?
