Aim – To see how the packing pellets dissolved in cold water
Materials – One glass beaker, 40ml cold water, one
Method – Place pellet into cold water. Observe what
physical/chemical changes happen to the pellet.
Results – Over time the packing pellets dissolved.
Observations – The water deformed the pellets and started to dissolve them. The packing pellets dissolve quicker in hot water.
Discussion – The packing pellets dissolved faster in the hot water than the cold water.
Conclusion – The packing pellets broke down and dissolved in the water. But the hot water was more efficient in dissolving the pellets.
Stop culling sharks,
Dear WA government, 87 Wilson st
Moonee Ponds VIC 3039
I am writing to put forward the idea to stop shark culling. It deeply saddens me to think that we are just randomly killing such a big part of our eco system. Not only me but thousands of other Australians are just like me arguing for the freedom of our sharks. You should listen to our scientific community. What they have to say is important. They have researched these topics for years and I know you’re just ignoring them.
I don’t know why we are killing particular types of sharks. These animals are a huge part of the food chain and our natural eco system. The Great White sharks are endangered but you see them as so much of a threat that you kill them. All humans and animals are equal and all have their own rights. How we have evolved in such a way that would drive us towards killing our animals shocks me. I’d hate to think what half-witted claims were going to make next.
I don’t know why you aren’t just ignoring everyone’s suggestions. Haven’t you seen the thousands of protesters gathering at beaches trying to be heard? Even professional scientists are disagreeing with your plans. Not only them but even shark attack victims are say this plan is idiotic. They way you’re using the nets are not only harm full to sharks but even humans. If anyone happens to swim to far they might get stuck.
Finally that what we are doing is evil. We should take responsibility of our lives, and realise that every time we go in the water that there are other animals as well as us. The risks we take are our own fault and shouldn’t wreck there habitat just because we don’t agree with it. Our natural world is at the point in time were it can’t handle all the pollution. Instead of putting in nets to kill sharks they could also kill dolphins and turtles.
I put forward this statement to not only the WA government but to everyone that thinks that wrecking our waters is a good idea. Implementing this plan is an extremely unintelligent thing to do. The risks that were putting our animals are ridiculous. Going forward with these plans will cut our shark population dramatically. For all the reasons above I hope that you accept this and take it into consideration.
Yours sincerely Jack L, MPPS
