A Memoir of the Cultural Revolution affiliate link — A juvenile non-fiction memoir of the Chinese Cultural Revolution, Red Scarf Girl is included in our reading list because it is a first hand account of the totalitarian communist regime that sought to destroy all pre-revolution values. Teaching Red Scarf Girl affiliate link provided copies of some primary source documents that enhanced the topic. A Thousand Splendid Suns affiliate link — Covering thirty years of Afghan history through the eyes of women who experienced freedom under the Soviets and oppression under the Taliban, A Thousand Splendid Suns is an important work that depicts how the lives of women are affected when totalitarian fundamentalists are in power.
For example, rock layers show the sequence of geological events, and the presence and amount of radioactive elements in rocks make it possible to determine their ages. Analyses of rock formations and the fossil record are used to establish relative ages.
In an undisturbed column of rock, the youngest rocks are at the top, and the oldest are at the bottom. Rock layers have sometimes been rearranged by tectonic forces; rearrangements can be seen or inferred, such as from inverted sequences of fossil types.
The rock record reveals that events on Earth can be catastrophic, occurring over hours to years, or gradual, occurring over thousands to millions of years. Records of fossils and other rocks also show past periods of massive extinctions and extensive volcanic activity. Although active geological processes, such as plate tectonics link to ESS2.
B and erosion, have destroyed or altered most of the very early rock record on Earth, some other objects in the solar system, such as asteroids and meteorites, have changed little over billions of years.

Major historical events include the formation of mountain chains and ocean basins, volcanic activity, the evolution and extinction of living organisms, periods of massive glaciation, and development of watersheds and rivers. Because many individual plant and animal species existed during known time periods e.
C By the end of grade 2. Some events on Earth occur in cycles, like day and night, and others have a beginning and an end, like a volcanic eruption. Some events, like an earthquake, happen very quickly; others, such as the formation of the Grand Canyon, occur very slowly, over a time period much longer than one can observe.
By the end of grade 5.
Earth has changed over time. Understanding how landforms develop, are weathered broken down into smaller piecesand erode get transported elsewhere can help infer the history of the current landscape.
Local, regional, and global patterns of rock formations reveal changes over time due to Earth forces, such as earthquakes. The presence and location of certain fossil types indicate the order in which rock layers were formed.
By the end of grade 8. Major historical events include the formation of mountain chains and ocean basins, the evolution and extinction of particular living organisms, volcanic eruptions, periods of massive glaciation, and development of watersheds and rivers through glaciation and water erosion.
Analyses of rock strata and the fossil record provide only relative dates, not an absolute scale.
I stumbled upon John Coltrane's Giant Steps in my local library. It offered so much more than I expected in a children's book! The CD included with the book is a must; this is really meant to be experienced as an entire package. The 5-Step Writing Process: From Brainstorming to Publishing. Every writer follows his or her own writing process. Often the process is a routine that comes naturally and is not a step-by-step guide to which writers refer. Writing can be one of the most daunting skills for some students to learn. Over time, however, students of any skill level can learn to write effectively with the right practice and instruction.
By the end of grade Radioactive decay lifetimes and isotopic content in rocks provide a way of dating rock formations and thereby fixing the scale of geological time. Continental rocks, which can be older than 4 billion years, are generally much older than rocks on the ocean floor, which are less than million years old.
Tectonic processes continually generate new ocean seafloor at ridges and destroy old seafloor at trenches. B and erosion, have destroyed or altered most of the very early rock record on Earth, other objects in the solar system, such as lunar rocks, asteroids, and meteorites, have changed little over billions of years.
Weather and climate are shaped by complex interactions involving sunlight, the ocean, the atmosphere, clouds, ice, land, and life forms. Earth is a complex system of interacting subsystems: The geosphere includes a hot and mostly metallic inner core; a mantle of hot, soft, solid rock; and a crust of rock, soil, and sediments.
The atmosphere is the envelope of gas surrounding the planet. The hydrosphere is the ice, water vapor, and liquid water in the atmosphere, ocean, lakes, streams, soils, and groundwater. The presence of living organisms of any type defines the biosphere; life can be found in many parts of the geosphere, hydrosphere, and atmosphere.Writers use the descriptive essay to create a vivid picture of a person, place, or thing.
