  • 1. Flour and water experiments By daughter April 23, 2014
  • 2. Question If you mix flour and water together, is it liquidy or does it bubble? Hypotheses My hypotheses are: -  None of the mixtures will bubble -  Some of the mixtures will be liquidy and some won’t depending on how much water I add.
  • 3. Experiments Three experiments with different amounts of flour and water Experiment Flour Water Experiment 1 1 cup 3 cups Experiment 2 ½ cup 2 cups Experiment 3 ½ cup ¼ cup
  • 4. Experimental protocol Materials: -  Flour -  Water -  3 bowls -  Spoon -  Measuring cup Method:   Measure  flour  and  water.  Add  flour  and  water  together   and  mix  with  spoon.  
  • 5. Data Experiment 1 It got a little bubbly and really liquidy.
  • 6. Data Experiment 2 There was a tiny bit of bubbles and it was pretty liquidy.
  • 7. Data Experiment 3 It got kind of doughy and there were no bubbles. It was like play-dough.
  • 8. Conclusions •  The mixture did bubble a little. My first hypothesis was not correct. •  Two of them were pretty liquidy and the other was doughy. It did depend on how much water I added. If I added more water it was more liquidy. My second hypothesis was correct.
  • 9. Conclusion Sometimes experiments can be really fun and sticky!
