The student conducted an experiment mixing different amounts of flour and water to see if the mixtures would bubble or be liquidy. Three experiments were performed using varying ratios of flour to water. The results found that the mixture with the most water bubbled slightly and was very liquidy, while the mixture with the least water became doughy with no bubbles. The student's hypothesis that the consistency would depend on the water amount was supported, but their hypothesis that none would bubble was not fully correct.

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!
