3. What happens if a hole is dug in the gravel below the water table? Water would fill the
bottom of the hole.
Experiment 1: Porosity

1. Which rock produced the most bubbles? The sandstone rock produced the most bubbles.
2. Which has more porosity: tightly packed particles or loosely packed particles? The
sandstone has a higher porosity while the granite has a lower porosity.
3. Which material is most porous? The least? The sandstone is more porous while the granite is
less porous.
4. Why do you think rocks with rounded grains absorb water more than rocks with interlocking
grains? Rocks with rounded grains are porous and therefore can absorb water in the gaps
between the grains and pours.
5. Would dolomite make a good aquifer? Yes.
