Conclusion
The pH meter had an uncertainity of about 0.1. The data we gathered shows that the pH is approximately 7.91 for the whole ocean. As the results were taken on 2 different days of the week we can say that the pH does not change alot thus is somewhat constant.It is necessary to note that this pH is almost neutral and because of this it supports a variety of acquatic life.
like barnacles,crabs, sea stars ,sea urchins ,sea lions and many others. In addition due to the constancy of the pH this life is able to last longer .From researched articles we learnt that a 0.2 -0.3 change in pH slows the calsification process thus the ocean is suitable.Lastly from these results we can say that the ocean is not so salty and thus low pollution.
The Pearsoon docks had a low pH which shows that there are more salts in the water where we stay and could signify the pollution we create in the docks.The Marina is second highest because there is alot of activity at this place like a store and quite as high pollution chances while people consume.However we can conclude that the water in the Pacific Ocean especially in Padder Bay is all at around a pH of 7.91

Results
We meeet another obstacle .........no one can use the pH meter and wow guess who we just met down at the docks ..........................GARTH.................
We quickly stumble down and grab this resource and ask him to help us and GOOODDD JOBBB GUYS ..................we have valid results.
A table showing the pH results for the samples taken today and on Thursday.
THEN TO THE MARINA ..................past the same Maxbell steps.
Slightly exhausted but we are too persevering to give up so..........................we keep moving.........down the hill and into the forest. It was now Elly's turn to get the water sample and with so much enthusiasm she heads out and hurrrraaayyyy!!!!!!!!!she has it.
And now its time for Elly to bring the sample and we head back BBBBBBUUUUUUTTTTT
ELLY is FALLING and she is STUCK IN THE MAD
THE PROJECT DAY!!!!!!!!!!!!!!!!!!!
The difference in the pH levels at the Wiers Beach, The Marina and Pearson docks.
We met today in the LLT at 8.30 and from Mark's "motivational" film clip we changed our idea from a boat ride to Race rocks to a walk to the beach and then we head off from the Maxbell steps.The walk to the beach was an enriching one both physically and socially
. Jose asked " guys ,what is your EE topics?" Emilia says "am so scewed cos am really not sure what question am doing in Biology>><<<<".We talked all the way down about advisors ,monsters even military service and we also got the water sample at the beach.We also saaaaaaaaaaawwwwww the beach it was so beauuuutifuuul.

Materials in...
So on Tuesday we spoke with Jonathan about the equipment for the project, everything is going as planned. Let's see how diferent is ph of the water in the marina, the docks and near race rocks.
Until next update.
Until next update.
