What Do We Do Now?!
(Salinity Test Groups)
Site Observation: You have 1 hour to observe 3 sites! For each site, do the following:
- Pick a placewhere there is salt water (kai), fresh water (wai), or brackish water (wai kai).
- Estimate an area of about 20 square feet & mark it off with stones.
- 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).
- Put on your gloves to collect a water sample and bring it to your chaperones &/or teachers who will help you:
- test the level of pH (acid & base)
- titrate the salinity (figure out the amount of salt)
- test the temperature of the water
- 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).

- Put on your gloves to collect a water sample and then do these tests – don’t forget to use the Data Sheet on the back to record the results of your tests (if you need help, bring it to your chaperones &/or teachers):
- test the level of pH (acid & base)
- testthe temperature of the water (see adult)
- test for nitrates
- test for dissolved oxygen
- test for phosphates
- Before you leave your site, collect all the rubbish you safely can.
