This year we will be learning about:
Earth Systems and Resources
- Weathering, Erosion, Deposition (chemical, physical, stream table)
- Rock Cycle (igneous, intrusive, extrusive, magm, lava, metamorphic, sedimentary, sediments)
- Earth Layers (crust, lithosphere, asthenosphere, mantle, outer core, inner core)
- Seismic Waves
- Plate Tectonics
- Divergent Plate Boundaries (mid-ocean ridges, seafloor spreading)
- Convergent Plate Boundaries (subduction, island arcs, folded mountains, trenches)
- Transform Plate Boundaries (San Andreas fault, faults)
- Continental Drift (Pangea)
- Hot Spots
- Evidence for Plate Tectonics
- Patterns of Earthquakes and Volcanoes
- Forces inside Earth (tension, compression, shearing)
- Convection Currents
- Catastrophic Earthquakes and Volcanoes
- Earth Resources (minerals, ores, fossil fuels)
- Physical and Chemical Properties (luster, texture)
- Newton's Laws of Motion
- Balanced vs. Unbalanced Net Forces
- Inertia
- Force = Mass x Acceleration (F=ma)

- Properties of Waves (amplitude, wavelength, frequency, crest, trough, rarefaction)
- Behavior of Waves (refraction, absorption, reflection, transmission)
- How do Rainbows Form?
- Interacting Waves (Interference)
- Standing Waves
- How we see in color
