Procedure drafts and week 7/25 homework

Pre-washing your sample:

Make sure balance is level
Weigh the beaker to find the weight before you put the sample in
Start to fill in the chart with all important information (Ex: Date, beaker #, weight of beaker, sample number)
Put sediment in beaker but leave a thumb sized amount in the bag in case other researchers need to use it later
Use bag sealer to reseal the bag
Weigh sample in the beaker
Finish filling in the previously mentioned chart with the weight of the sample in the beaker

Foraminifera (forams) are dust-sized protists that live at the bottom of the ocean. These fossils are collected by drilling into the ocean floor. The Geology lab looks at fossilized forams and uses them to measure the climate, and ocean acidity of different geologic time periods. Ocean acidification is when the ocean takes in fossil fuels such as carbon dioxide which change the pH levels of the water. If the pH gets too low, the ocean is more acidic. When the ocean is more acidic, Foraminifera shells are thinner because they don’t have enough calcium carbonate to make strong shells. This can affect us because animals that make shells in the water are eaten by larger fish and we eat some of those fish. If animals can't make their shells they start to die off and that can seriously affect our food supply.

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've come a long way in women's advancements. Back in the late 1800s to early 1900s women in science were usually unpaid volunteers and their colleagues and husbands would take credit for their work. Now women are paid to work in science fields and able to publish their work without it being stolen. We still have some ways to go though because some people still take credit for other's work. Also women aren't yet paid equally to men.
