conclusion/ question

1. Define the term salinity

The amount of salt in something

2. If you add salt to a water solution, will a hydrometer float higher or lower in the water?

lower because it was more dense

3. What effect does the addition of salt have on the properties of water?

it makes the salinity level's higher

4. Is it easier to float in the ocean than a swimming pool?

a pool because an ocean has more salt than in a pool

5. Define the term density 

a ratio of the amount mass per unit volume

6. The salinity of seawater is also affected by the temperature of a body of water. Explain how temperature causes differences in the salinity of water

because when it's hot, the molecules of the salt start to move more and multiply

It's all connected

Analysis of Results:

1.   Why do you think there are international laws for dumping waste/trash/chemicals in the ocean, rather than just local laws? Do these laws only need to extend to nearby neighboring countries? Explain. 
    There are international laws for dumping waste into the ocean so that  everyone has the same law to follow. Having this international law they are hoping that everyone around will not violate this law by throwing waste into the ocean. Now more people will follow this law because they would get more trouble having it be an international  law. 
  1. What else can be done to protect the oceans from being the repository for waste?
Have larger fine given to the people that get caught. Also they can make a bigger deal about how important the ocean is and try to get peoples attention on how the waste in the ocean can harm our environment.
