Science Experiment
Question: Does it take more water, less water, or the same amount of water to cover and irregular surface than it does to cover a regular surface of the same volume?
Research: Gravity pulls water to the low places leaving the high places exposed
Hypothesis: I think it will take more water to cover the irregular surface than it takes to cover the regular surface.


We smoothed the sand to make it fairly even.





Analisis: The sand that was piled up stuck out of the water even though no water or sand was added or taken away.
Conclusion: We would need to add more water to cover the irregular surface. It takes more water to cover an irregular surface that it does to cover a regular surface of the same volume.
