Science 8th Grade
First Semester
I learned about mapping the earth with latitude and longitude, topographic maps and making and reading them, magnetic pole and geographic pole, types of soil and weathering, types of chemical and physical weathering, soil composition, cave formation, porosity and permeability and more.

In this lab report, students were to report the effect of a meander of a stream on the erosion and deposition in a stream bend. I learned that meandering rivers are rivers that curves due to the less steep land it is sitting on. In a meandering river, there is a cut bank and a point bar. Cut banks are located on the outside of the meanders of the river while point bars are located on the inside of the curve. On the outside area of the curve, there occurs high velocity water which causes erosion, or movement of sediments to be relocated. On the inside where the point bar is, there is low water velocity resulting in sediments to deposit. Another thing I learned through this lab report is that a constraint of a lab is not things like human error, which was what I had written on this lab. A constraint is actually limitations that make this lab unrealistic compared to nature in real life.
Additionally to what I learned about erosion and deposition, I learned about canyon and delta, river features, water shed, drainage basin, cliff models, glacial movement, dune formation, sediment sorting and transportation, weather and climate, uneven heating, the atmosphere, air temperature (relative humidity and dew point), air movement, global winds, cloud formation and more.

Third Semester
I learned about hurricanes and how to track them, what are isobars and isotherms and how to read and write them, reading weather maps, surface currents, climate, plate tectonics, earthquakes and how to plot them, reading a seismograph, earth's interior, faults, the theory of continental drift, the mid-Atlantic ridge, and sea-floor spreading. For climate, I was assigned a climate investigation lab report on the topic of the effect of the Location in The Cascade Mountain Range, Seattle or Spokane, on the Precipitation on Either Area (Seattle, WA and Spokane, WA).
