The earth's climate has changed greatly over the course of millions of years. The Geology lab studies how small microfossils called foraminifera (forams) tell what the climate was like millions of years of ago. The lab studies how forams and their shells can tell us about the how the climate and about the acidity levels of the ocean thousands and millions of years ago. By studying the shells and how much calcium carbonate are in the shells it tells researchers exactly how acidic the ocean was. It is important that researchers know how acidic the ocean was and how it affected sea life, like shellfish, and corals. If researchers know that information then they can predict what will happen to sea life if the pH levels in the ocean keep dropping. It is important that we know about the climate then and now because that way researchers can predict how climate changes like global warming, rises in CO2, and drops in pH levels will affect all of us and sea life in the long run.

Washing samples:

1. Get a 63 micrometers sieve and place it in the sink.
2. Pour the wet sample that is in the beaker in the sieve that is in the sink.
3. If part of the sample remains in the beaker use the nozzle with a gentle spray of deionized water , that is strong enough to remove the sample but not too strong or the sample will go everywhere.
4. To test the strength of the nozzle, turn it on AWAY from the sieve and test on your hand, it feels too strong then turn it down until it feels really gentle.
5. Using the nozzle wash the sample in the sieve for thirty minutes.
6. While washing move the nozzle slowly in an up and down motion or in a side to side motion. This will break up some of large clusters of clay and/or forams
7. To test if the sample is clean after thirty minutes place the beaker under the sieve and let the water fill the beaker.
8. If the water is cloudy add another fifteen minutes, and if it is still cloudy after that then it may need a second wash.
9. To remove the sample from the sieve, place a circle piece of filter paper in a funnel and put it in the same beaker you used in the beginning.
10. Using a spray bottle with Deionized water to gently remove the sample from the sieve into the filter paper.
11. After that is done, place the sample in the dry oven over night
12. Clean sink, station, and place sieve in sieve washer.

Do you think we've come a long way or we've still got ways to go when it comes to woman's advancements and giving people proper credit when it comes to working and fair pay? 

I think we still have a ways to go to when it comes to fair pay and giving women proper credits. There are cases when equal pay and credit is given but there are still a lot of instances were women do not receive equal pay or credit. In the case of Katherine Bush she received proper credit and pay most of the time but she was unable to join expeditions because she was a woman. However she was able to publish work.
