  1. Water habitats project Prepared by Mr. Rabeea Hussein Chemistry teacher + his students team work MBAW independent secondary school for boys 2009-2010

  2. Introduction to our project • We use scientific method in our project as following

  3. Introduction to the Scientific Process Use conclusions to develop a new hypothesis

  4. Step 1: Our big question How can we convert sea water to soft water ?

  5. 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

  6. 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?

  7. 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

  8. 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

  9. Variables • Area of water • Temperature • Effect of universal indicator • PH • T.D.S value

  10. Step 5: Record and Organize Data

  11. Step 6: Analyze Data

  12. 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
