[21-Jul-2022] We all know the oceans are salty, but so are other sources of water. The oceans have a salinity (salt content)
of 35 parts per thousand (‰). The Dead Sea has an average salinity of 290‰, almost nine times saltier than
the oceans. But what does that actually mean? Just how salty tasting are these various bodies of water? With
up to seven containers of water and table salt, students can "taste test" simulations of various bodies of
water around the earth, concluding with the impressively high salinity found in the Dead Sea. This 25-minute
experience may be geared towards younger students, but can be an eye-opening activity at any age when combined
with discussions about the water cycle (e.g., distillation of water during evaporation process, global evaporation
and precipitation rates, and influx of salts to oceans).
