Sustainable Fishing

 Is Sustainable Fishing Possible?

  • There are less damaging ways to fish and better ways, Because there is no such thing as sustainable fishing.

How is commercial fishing a threat to dolphins and bird life?

  • It’s maybe a threat to dolphins because of the nets they use to catch the kinds of fish, and  The use of long strands of rope and nets can entangle whales and dolphins at a high enough level that populations can become threatened - and can have an especially significant impact in the case of endangered species.

  • Dolphins die in foreign fisheries every year due to being hooked or entangled in nets and other fishing gear.  

What is Bycatch?

  • the unwanted fish and other marine creatures trapped by commercial fishing nets during fishing for a different species.

Dilution Experiment

What is Dilution: 

Making something less concentrated 

there will be less particles in the liquid

Hypothesis: which test tube is the most dilute? 

last one 

which test tube will be the lest dilute?

What did I do:

  • first we added 10 mils to the first test tube then we added 5 mils to the other 5 test tubes and after that there was a chemical that got added which had made it turn into a sorta dark bright purple colour.
Was my hypothesis correct - it sort of was right...
How did I know: when i was giving it ago and to see what the result would be when 
i found out what happened but comparing it with what i thought would happen which one
would be diluted...

Filtration Experiment

 Aim: Separate a mixture we have made using filtration...

Hypothesis: I think that they may separate and change colour.

When we mixed it, the colour turned into a darker blue, after that we then filtered it and one the blue one changed into a solid and the other then started falling down to a liquid... when we were filtering it, the blue one didn't go down but the other clear liquid did...
