Week12's Blog

This week's lab we check the difference of the 11 kinds of the tiny rocks under the microscope. Here is our group's record and data collect: (which hand record by Kaye Le

• 1. The Big Question Addressed in Lab:

• The lab focused on understanding the layers of the earth based on rock cycle by modeling the formation of different rock types.
• What Erosion cause the different rocks and what is the influence of that?
• 2. Lab Activities:
• We observed these 11 different rock samples with a microscope and recorded and organized the data, as documented on the figure above.

• 3. Lecture Insights from Thursday:
• We learned about buoyancy, which also amounted to a lab session where different drinks were used to test whether they floated or sank, introducing the fact that because of the difference in sugar and weight, the cans sank and floated.

• What did I learn?

• I learned that different brands of beverages can be buoyant in different ways, as well as that different materials sink and float differently, and that different rocks have different appearances, and that they are made up of different components.

• Also, we learned about the Layer of the earth, The earth is made up of different piles of rocks that have accumulated based on time.

• What was most helpful?

• I found the presentation of the experiment and our personal observations most helpful.

• What do I need more information on?

• Figure out what is the individual rocks form and how the rock cycle works.

• Questions/Concerns/Comments:
• For the results of these erosions, what substantial impact do they have on our lives?
