 Lab 





Today in the lab, we dove into the different layers of rock formations, exploring the sequence of their formation based on rock types and layer positioning. Transitioning from theory to practice, we examined diverse unidentified sands under a microscope, within our table groups to try and identify where the sand originated

This week's big question is how does weathering and erosion help us identify where rocks originate and how they are formed.

Lecture

Today in the lecture we did a lab, we began the lab by talking about buoyancy which is the process by which something floats or sinks. There is a relationship between how dense something is compared to water, if something is dense then water sinks if there is something less than water it floats. We read a book called Archimedes, the purpose of this book was to teach us about how we could use water displacement to understand if something will sink or float. We talked about how the water that is displaced shows the amount of volume an item has, and that is how we can measure the volume between two items due to the displacement amount. We talked about Archimedes' Law with Geodes specific gravity= W (air)/(W (air)- W (water)) if the geode is 100% solid quarts we would get 2.7 if the geode is 50% hollow we would get 1.35. The goal of this lecture was to show how geology and bouncy work together.

Pressbook

I learned in the pressbook about where different types of sand come form. According to the pressbook sand comes from dunes in the desert and rocks near the water.

The table "Where did this sand come from?" I found it to be the most helpful because I was confused about the characteristics as well as the location of where sand comes from, and after seeing this table it made the location and characteristics make a lot more sense. I would like more information on the Archimedes equation, because I find the equation to be quite confusing so I need more practice working on it.
