Based on data collected by student`s, they will determine the average amount ofwater used at home. YOUR TASK….
PHASE 1: TheoryExplain the difference between the terms "volume" and "capacity“. Make a comparative chart. VOLUME VS CAPACITY
PHASE 2: PREDICTION.Get a Gallon ContainerGet 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?

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.
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
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.

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.
