Weekly Homework 7/10/16

How does ocean acidification effect us?

Ocean acidification is caused by the rising level of carbon dioxide being admitted and soaked into the ocean water. Due to the more acidic water, sea animals like, sea butterflies, crabs, and shrimp have a harder time building their shells and become more vulnerable. Sea butterflies in particular are staples in the diets of marine animals such as salmon. Salmon and other fish are food for us and this could seriously affect the amount of food for countries like Japan.

Would we study kelp in the botany lab? Why or why not?

We would study kelp in the botany lab because kelp can be used to reduce the acidity in the oceans. It should also be studied because it can be used as a food source and is easy to maintain.

In what ways is growing kelp beneficial to the environment and economy?

Growing kelp can be beneficial to the environment because we can use it to reduce our fossil fuel usage by being converted into biofuel. They can also save the U.S. about $82 million per year by harboring bacteria that can fend off the growth of toxic algae which can kill fish.

This week we learned about geologic time clocks and made our own using a roll of toilet paper. This was to show the actual time differences in the history off earth. this activity was supposed to help us understand what time time difference between some of the forams can be. Seeing it all laid out showed me that humans really haven't been here long at all and dinosaurs went extinct much more recently than I thought. We also learned how to wash and pre wash samples and were actually able to wash some even though most of them needed a second wash. We have to do this so that the clay chunks can break up and we can be able to see individual forams when they're put under the microscope. Then we learned how to bottle the clear samples so they can be studied.
