A hydrometer is a device used to measure the salinity of water. I built my own hydrometer using a pipet, BBs, and clay. On my hydrometer, I marked a line every half cm so that I would be able to measure the salinity. Salinity is the amount of salt in the water. The hydrometer floats higher the higher that the salinity gets. The addition of salt to water causes the water to be more dense. When the water is more dense it is easier to float on. Density is how thick/thin something is. The salinity of water can also be affected by the temperature. Warmer water has less salinity because there is more energy, moving the salt around. Cold water has less salinity because the water condenses.
