Watch the animation below on porosity and permeability. Make sure to record the following: For the porosity experiment, write down the amount of water poured into each beaker. This is calculated by subtracting the amount of water left behind in the measuring cup from 100ml. For the permeability experiment, write down the time it took the water to filter through the rocks into each of the three different beakers.
