Flour and water experiments
By daughter April 23, 2014
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.
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
Experimental protocol
Materials: - Flour - Water - 3 bowls - Spoon - Measuring cup
Method: Measure flour and water. Add flour and water together and mix with spoon.
Data
Experiment 1
It got a little bubbly and really liquidy.
Data
Experiment 2
There was a tiny bit of bubbles and it was pretty liquidy.
Data
Experiment 3
It got kind of doughy and there were no bubbles. It was like play-dough.
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.
Conclusion
Sometimes experiments can be really fun and
sticky!
