Teacher Grant Recipient

Science – Lab Equipment
Amount Awarded: $500

The PREA grant has been especially helpful for our fledgling Marine Biology program at the high school. In its first year, I am working hard to build a rigorous lab schedule. The PREA grant made it possible to order a class set of hydrometers that my students can use to measure the density of sea water and the water in our aquarium. That density is then used to calculate salinity of the water after we take into account the temperature. We also got 2 refractometers that students use to determine the salinity of seawater based on the refractive index of saline water, denser water bends the light more. My physical oceanography unit just got a whole lot more applicable with these new tools that PREA bought for us.
