We also tested materials to compare how much water they could hold, and learned that nylon fabric would make an excellent umbrella cover (because it was waterproof and absorbed 0 mL), and sponge would work very well to clean up spilled water (because it absorbed a whopping 49 mL). Stay tuned, because later on in this unit, we will conduct consumer testing to determine which paper towel brands absorb the most water.
In our continuing exploration of liquids in Science, we’ve been experimenting to see how absorbent different materials are. One of the scientists in our class generously donated a bunch of water beads so that each student could absorb the the beads before and after being placed in water. Suffice it to say that water beads are an extremely absorbent material!
