We learned about landforms created by deposition. These landforms are flat and low-lying, such as mountain streams that reach the gentle slopes of wide, flat valleys or plains at the bottom of slopes that form alluvial fans. Deposition occurs when water slows down or loses energy. Deposition also occurs as glaciers melt leaving behind piles of sediment and rock called eskers or moraines. Next we played a game where we answered questions on types of rock.
We reviewed the parts of the Eukaryotic and Prokaryotic cells to prepare for a test. Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
We learned that the presence and location of certain fossil types indicate the order in which rock layers were formed. Then we learned about Earth materials and systems such as water, ice, wind, living organisms, and gravity that breaks rocks, soils, and sediments into smaller particles and moves them around. We learned that the Earth is constantly changing being reshaped by constructive and destructive processes. Constructive processes such as the cooling of lava build up features on Earth’s surface but destructive processes such as strong hurricanes tear down features on Earth’s surface. The process by which glaciers, wind, or water carry sediments to new locations is called erosion. Then we learned that the rate of erosion depends on the type of rock, for example, sandstone rocks break into large pieces but shale rocks break into small pieces. We learned that landforms created by erosion such as the Painted Desert of Arizona contain several layers of different materials. Then we looked at some national parks with unusual landforms and learned how the formations occurred.
We created a rocks and minerals game that helped us learn the history of planet Earth. We learned about local, regional, and global patterns of rock formations. This activity revealed changes over time due to earth forces such as earthquakes. We looked at the hoodoo shapes in Bryce Canyon. We learned that they were formed in sedimentary rock, hoodoo shapes are affected by the erosional patterns of alternating hard and softer rock layers. The name given to the rock layer that forms hoodoos at Bryce Canyon is the Claron Formation. This layer has several rock types including siltstones and mudstones but is predominantly limestone.
We explored the physical sciences concerned with the study of inanimate natural objects, including physics, chemistry, astronomy, and related subjects. We played a game where we learned about supernovas, constellations, and planets.
Space Facts Game
We played a game answering questions about planets, stars, and other objects in space. This increased our understanding of asteroids to meteorites, comets, and galaxies. Yanuell did extremely well.
Lesson 1 Forms of Energy
We learned that energy is not only the ability to cause change but the ability to do work. Then we identified the differences between potential and kinetic energy. Next we reviewed the concepts of gravitational, elastic, and chemical potential energy.
