Students will collect data on average home water usage. They will determine the volumes and capacities of containers, make predictions about typical water usage activities, and measure water usage for various tasks like showering, flushing toilets, and handwashing. Students will calculate their daily and monthly water usage and propose ways to conserve water at home through changed habits and new technologies.

PROJECT

5. Based on data
collected by
student`s, they will
determine the
average amount of
water used at home.
YOUR TASK….

6. PHASE 1: Theory
Explain the difference between the terms "volume" and
"capacity“. Make a comparative chart.
VOLUME VS CAPACITY

7. PHASE 2: PREDICTION.
Get a Gallon Container
Get a clear plastic gallon container . Fill it up with water.
Make a Guess
Take a good look at the gallon of
water. How many gallons do you
think you would use Flush the toilet?
to Wash your hands? Get a drink?
Brush your teeth? Wash the dishes?
Take a shower? Water the flowers?
Wash the car?

8. PHASE 3: AT HOME
Find out the quantity of water (liters) that
comes out of the faucet during a
period of time. ( cups, quarts and
pints).
To perform the measuring, use a
container that shows the volume it
can hold (a bottle of soda, or a box of
milk) and put it in the sink. Let the
water running directly to the container
for thirty seconds. Observe the
quantity of water, and multiply it by
two. The result will be the water flow
spent every minute.

9. a. What is the measure of the water flow?
Continue your experience in the bathroom,
which is responsible for 65%-70% of the
spending of the water in our homes.
b. How much time do you spend while taking a
shower?
c. How many times a day do you do that?
d. How many times in a week do you take a
shower?
E. Propose two word problems.
PROBLEM SOLUTION ANSWER

10. EXAMPLE OF A REGISTRATION TABLE

11. 2. In the bathroom, using the toilet is an activity that consumes a lot of
water. Every time we flush the toilet we spend between 10 and 15
liters, depending on the capacity of the instrument. Think about the
“flushing frequency” along one day.
a. How many times do you flush the toilet in 24 hours?
Finally, we will include two activities about our cleanliness that we do
everyday: brushing our teeth and washing our hands.
b. How long does it take to brush your teeth? How much water do
you spend?
c. How many times a day , a month, do you brush your teeth?
d. How long does it take to wash your hands? How much water do you
spend?

12. PHASE 4 :ESTIMATING
Use the information you have found in the
experience, and calculate the amount of water
that is being spent with those activities.
1. How much water do you spend in one day?
Write in liters and gallons.
2. How much water do you spend in one month?
Write in liters and gallons.

13. PHASE 5: PROPOSAL…
Do you have what it takes to be a water conservationist? What are some things
that you can do at home to help to conserve water?
Thing about everything you have learned so far. How might you change your
habits at home (inside and outside) to reduce your water usage? What
practices do water conservationists recommend? Are there any types of new
technologies that might help to reduce water usage? Make a small
proposal.
