Spring SAVY 2017, Day 3- Science of the Sea: Diving into Marine Biology

Posted by hallep on Tuesday, February 14, 2017 in Grade 1, Grade 2, SAVY.

Today in Marine Biology we learned some chemistry, especially chemistry of the ocean. We first completed a quick background in matter and atoms. We then investigated how these atoms formed charges which lead to ionic bonds. Some molecules that form ionic bonds are salts, but not just the table salt we normally think of. Salts are common chemical and a lot of them are found in the ocean. We made different ionic molecules by balancing out charges and figured out why water’s chemical symbol is H2O. We discussed the ways the ocean ecosystem could by damaged by excess chemicals from fertilizers or greenhouse gases. We also investigated animals and the oceanic zones they live in. Animals of the abyss zone tend to converse energy with slow swimming, and have bioluminescence to either attract prey or confuse predators. Animals that eat plants tend to live in the sunlight zone and often are either quick swimmers or camouflaged for protection. Next week we will be looking at the water samples you brought in and talking about how animals are adapting for their environments.
