Water habitats project

Prepared by

Mr. Rabeea Hussein Chemistry teacher + his students team work

MBAW independent secondary school for boys

2009-2010


Introduction to our project
Introduction to our project

  • We use scientific method in our project as following


Introduction to the scientific process
Introduction to the Scientific Process

Use conclusions to develop a new hypothesis


Step 1 our big question
Step 1: Our big question

How can we convert sea water to soft water ?


Step 2 gather information
Step 2: Gather Information

  • Use references to do background research

    • Internet:

      1-http://www.newworldencyclopedia.org/entry/Water

      2-

    • Interview Experts:-

      AlShaker company for water treatment


Step 3 formulate a hypothesis
Step 3: Formulate a Hypothesis

Hypothesis

we hypothesis that if the water has high TDS value then we can convert it to soft water by evaporation because of the evaporation separate the salt from the water

1-CAN BUILD UP A MODEL OFAQUATIC QATER SEA WATER?(Y/N)2-HOW MUCH THE T.D.S OF QATER SEA WATER ?3-WHAT IS THE EFFECT OF HEATING ON T.D.S OF QATER SEA WATER? 4-CAN YOU BUILD A DEVICE TO CONVERT HARD WATER TO SOFT WATER?


Step 4 develop an experiment
Step 4: Develop an Experiment

Materials:

  • three Samples of water from:

    al wakra –alkhour –alkornich areas

  • Supplies:

    T.D.S meter

    pH meter

    Heater

    Thermometer

    Aquarium

    Tow dish ( one thermal glass + one ceramic)

    Thermal plastic sheet

    Coin

    Thermals Wool


Procedure

  • Teacher divided students to three groups:-

    a-Group 1 (3 students) :make aquatic Qatarian environmental

    b-Group 2 (3 students) :analysis the three samples of water by T.D.S meter , pH meter and thermometer and take the results for each samples 3 times for each experiment

    c-Group 3 (2 students) :make a MBAW device for converting hard water to soft water


Variables
Variables

  • Area of water

  • Temperature

  • Effect of universal indicator

  • PH

  • T.D.S value




Step 7 make conclusions
Step 7: Make Conclusions

  • You must repeat the experiment to make the data valid three times at least

Our conclusion :

1-

T.D.S IS VERY HIGH IN QATAR SEA WATER.

2-

WE CAN BUILD A SIMPLE MBAW DEVICE FOR CONVERT HARD WATER TO SOFT WATER
