What Do We Do Now?!

(Salinity Test Groups)

Site Observation: You have 1 hour to observe 3 sites! For each site, do the following:

  1. Pick a placewhere there is salt water (kai), fresh water (wai), or brackish water (wai kai).
  1. Estimate an area of about 20 square feet & mark it off with stones.
  1. Make a drawing of the area (site). Include all the rocks, limu, plants, litter, fish, bugs, etc. you can see in the drawing. Also, draw where the water source is (stream, pond&/or high/low ocean tide lines).
  1. Put on your gloves to collect a water sample and bring it to your chaperones &/or teachers who will help you:
  2. test the level of pH (acid & base)
  3. titrate the salinity (figure out the amount of salt)
  4. test the temperature of the water
  1. Before you leave your site, collect all the rubbish you safely can.

* TAKE NOTE!

What could people do to care for your sites better?

BONUS: If you have time, ask an adult to help you test the turbidity of the water (how murky or cloudy it is).
