Introduction to our project
• We use scientific method in our project as following
Introduction to the Scientific Process
Identify a problem
Gather Information
Formulate a hypothesis
Design and Experiment
Record and Organize DataAnalyze Data
Draw Conclusions
Use conclusions to develop a new hypothesis
Step 1: Our big question
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
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 ExperimentMaterials:
• three Samples of water from: al wakra –alkhour –alkornich areas• Supplies:T.D.S meterpH meter HeaterThermometer
Aquarium Tow dish ( one thermal glass + one ceramic)Thermal plastic sheetCoin
Thermals Wool
• Teacher divided students to three groups:-a-Group 1 (3 students) :make aquatic Qatarian
environmentalb-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
• Area of water• Temperature• Effect of universal indicator• PH• T.D.S value
Step 5: Record and Organize Data
AreaT.D.S T.D.S T.D.S
Alwakra 500 487 502
Alkornich 400 432 450
Alkhour 490 479 480
Step 6: Analyze Data

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
