Laws Of Exponents
This document introduces the laws of exponents. It defines key terms like exponent, base, and power. It then outlines six laws of exponents: 1) the product law, 2) the quotient law, 3) the power law, 4) powers with different bases, 5) zero exponents, and 6) negative exponents. It concludes by explaining how to simplify powers and exponential expressions by applying these laws and definitions of exponents.
Slope Intercept Form
The document discusses key concepts for graphing linear equations including slope, slope-intercept form, and steps for graphing equations. It defines slope as the ratio of rise over run, or the vertical change over the horizontal change along a line. Slope-intercept form is defined as y=mx+b, where m is the slope and b is the y-intercept. Examples are given for finding the slope and y-intercept and writing equations in slope-intercept form.
Dacota_blue K12: Science 7: Quarter 1: Module 1 matter
This document discusses solutions and related concepts. It begins by defining matter and the different states of matter.

Examples are provided throughout to illustrate these concepts. Concentration is discussed further, including percentage by weight and by volume. Factors that affect how quickly solutes dissolve are also outlined.
1) exponential equations
This document discusses exponential functions and equations. It explores the properties of exponential functions by examining their graphs and understanding exponential growth and decay. It also covers how to solve problems leading to exponential equations by learning about bases, exponents, powers, and index rules. The document teaches how to evaluate, write in different bases, identify exponential equations, and solve exponential equations. It includes exercises to solve from the attached document on exponential equations and functions.
Force and motion remind (2)
Newton's three laws of motion describe the relationship between forces and motion:
1) An object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force.
2) The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force.
3) For every action, there is an equal and opposite reaction.
the nature of solution
Mixtures consist of two or more substances that retain their individual properties. A solution is a homogeneous mixture where the components are uniformly distributed at the molecular level. A solution has a solute dissolved in a solvent. The ability of a substance to dissolve, or solubility, depends on factors like the nature of the solute and solvent, temperature, and pressure. Solubility generally increases with temperature for solids and decreases with temperature for gases, and increases with pressure for gases according to Henry's Law.

Tang 06 bond energy
All chemical reactions involve breaking old bonds and forming new ones. Bond breaking is endothermic as it requires energy, while bond formation is exothermic as it releases energy. The heat absorbed or released in a reaction comes from the breaking and forming of chemical bonds. The greater the bond energy, the stronger the bond. Bond energies can be used to calculate the enthalpy change (ΔH) of a reaction by adding the bond energies of reactants and subtracting the bond energies of products.
Substances and Mixtures
This document discusses the differences between substances, mixtures, and compounds. It defines a substance as matter made of the same atoms, and notes that elements and compounds are types of substances. A mixture is two or more substances physically blended but not chemically bonded. Granite and air are given as examples of heterogeneous and homogeneous mixtures respectively. The document explains that mixtures can be separated into their original substances using physical means, while compounds require chemical changes to separate them into their component elements.
Introduction To Equations
The document discusses equations and solving equations. It defines an equation as a statement of equality between two or more quantities that always includes an equal sign. Equations can be true, false, or open. To solve an equation means to find the value of the variable that makes the statement true. The document provides examples of different types of equations and introduces the cover-up method for solving equations.

I disagree with the statement that all natural chemicals are not harmful and all synthetic chemicals are highly dangerous. Here are three reasons why:
1) Many natural chemicals can be harmful in large quantities, such as arsenic or snake venom.
2) Not all synthetic chemicals are inherently dangerous. Many are designed to improve quality of life, like medicines or food additives.
3) Whether a chemical is natural or synthetic does not determine if it is safe - its chemical properties and how it interacts with the body determine if it is harmful or not. Some natural chemicals can be toxic in small amounts while synthetic chemicals can be safely used.
1. structure-of-the-earth (1)
The document discusses the structure of the Earth and compares it to a hard boiled egg. It explains that the Earth has four main layers - the crust, mantle, outer core, and inner core. The crust is the solid outer layer made of rocky plates, the mantle is below the crust and made of molten rock, the outer core is very hot molten metal, and the inner core is solid metal. Cutting open a hard boiled egg reveals similarities to the Earth's layered structure.

States of Matter
This document provides an overview of atomic structure and the states of matter. It begins by asking questions about what the atomic number and atomic mass tell us. It then discusses how to determine the number of protons, electrons, and neutrons in an atom using the periodic table. Diagrams of helium and boron atoms illustrate their particle arrangement in different energy levels. Students are tasked with drawing particle diagrams for two additional elements. The document then covers the three states of matter - solid, liquid, and gas - and how the density and motion of particles changes between each state. It defines the law of conservation of matter and provides an example.
Periodic Table
The document provides instruction on how the periodic table is organized and how to classify elements. It explains that the periodic table is like a calendar, with groups represented by vertical columns and periods represented by horizontal rows. Elements are classified based on their location, with metals mostly found on the left side, nonmetals on the right, and metalloids between them. Specific groups like the halogens in group 17 and noble gases in group 18 are also identified. Students are then asked to locate elements based on their group and period number and to classify different elements.
Inca day 7
The document provides an overview of a lesson on the Inca Empire, including an essential question about similarities and differences between Inca society and modern life. Students will watch a video on the Inca Empire and note interesting facts in their journal. They will then create a foldable to summarize key aspects of Inca government, organization, and farming in their own words with pictures and explanations of importance.
Day 6 Aztecs
The Aztecs established a system of public schools in their capital city of Tenochtitlan where attendance was mandatory for all children, including girls and slaves. There were separate schools for girls, sons of nobles, and sons of commoners and slaves. The schools trained students in specialized professions like farming, trade, engineering and more. As the population grew, Aztec engineers created floating gardens on Lake Texcoco to produce more food.
Day 4 Timeline lesson easley
This document provides instructions for making and reading timelines to help organize and study history. It begins with an essential question about how timelines can help learn history and sets a goal of developing timeline skills for middle school, high school, and beyond. Students then watch a Pixar clip and take notes on plot events to create a class timeline. The document reviews five rules for making timelines, including drawing arrows and using AD/BC dating. It includes activities where students practice timelining dates and summarize timeline rules. In the end, it reviews ancient Greece and Rome through a map activity.
Elements and Atoms
The periodic table can be used to determine the structure of an atom. The atomic number indicates the number of protons in the nucleus, while the atomic mass provides the total number of protons and neutrons. By subtracting the atomic number from the atomic mass, we can calculate the number of neutrons. The periodic table also shows the arrangement of elements by increasing atomic number and energy levels which indicate where electrons are located around the nucleus.
Day 10 evolution
The document provides information about geologic evolution and biologic evolution.
1. It asks how geologic evolution, which is the changes to the Earth over time, relates to biologic evolution, which is the changes to species over time.
2. It lists key vocabulary like adaptation, natural selection, and common ancestor that are important to understanding both geologic and biologic evolution.
3. Geologic evolution involves how the Earth changes over time, while biologic evolution is how species change over time through inherited traits, adaptations, and natural selection of those adaptations best suited for the environment.
Day 9 geo time scale
The geologic time scale is divided by major changes or events such as mass extinctions and the development of new species.
Day 8 weathering unconformity
The document discusses weathering and provides examples of mechanical and chemical weathering. It notes that mechanical weathering breaks rocks into smaller pieces without changing their chemical composition, while chemical weathering chemically alters rocks often changing their color. The document aims to explain the differences between these two types of weathering.
Day 7 superposition fossils
The document provides instructions and questions for a classroom bell ringer activity about fossils, including what fossils are, how they form, and how tree rings can indicate past weather; it also asks students to make assumptions about an area based on finding seashell casts, petrified wood, and to provide class rules for group work and listening.
Day 3 Earth Layers
The document discusses how continental drift occurs through plate tectonics. It explains that convection currents in the asthenosphere, the liquid layer between the lithosphere and outer core, cause the movement of tectonic plates. Hot magma in the mantle rises due to convection currents, cools and sinks, moving the rigid tectonic plates comprising the lithosphere. This continuous cycling of magma drives the drifting of continents via plate tectonics.
Day 2 Continental Drift
Scientists found tropical plant fossils like coconut fossils in Antarctica, where the climate is now very cold. This provided evidence that the continents have moved over time, as the same types of fossils are only found in tropical areas currently. Therefore, the continents could not have always been in their current positions.
Day 3 Earth Layers
The document discusses how continental drift occurs through plate tectonics. It explains that convection currents in the asthenosphere, the liquid layer between the lithosphere and inner core, cause the movement of tectonic plates. Hot magma in the mantle rises due to convection currents, cools and sinks, moving the rigid tectonic plates comprising the lithosphere over geologic time. This cyclical movement of magma drives the drifting of continents via plate tectonics.
Earthquakes
Most earthquakes occur along tectonic plate boundaries and are caused by the buildup and sudden release of stress in rock. Rock can deform plastically or elastically under stress, and will break if stretched too far, releasing seismic energy. The type and strength of earthquake depends on the type of plate boundary, with transform boundaries producing moderate quakes, convergent boundaries producing strong deep quakes, and divergent boundaries producing weak shallow quakes.
Native americans and North Carolina
This document provides instructions for a lesson on the Native Americans who settled North America and North Carolina. Students are asked to read about the five largest Native American groups in North Carolina and how many Native Americans lived in the present-day state. They then work with peers to answer questions about why Europeans may have been shocked by Native Americans' appearance and reasons why Native Americans found European arrival threatening. Finally, students are to write a four sentence summary answering who settled the Americas and North Carolina, and what culture Native Americans developed to survive.
Settlers in The New World
Here are the answers to the Chapter 4 review questions in your notebook:
16. Tobacco became the cash crop that saved Jamestown.
17. John Smith enforced strict rules and discipline to get the colonists to work.
18. Pocahontas helped the colonists by bringing them food during the Starving Time.
19. John Rolfe experimented with different tobacco varieties and cultivation methods.
20. The headright system gave colonists land for each immigrant they brought over.
21. Indentured servitude provided labor for the tobacco plantations.
25. John Smith, John Rolfe, and Lord De La Warr helped establish order and find economic success at Jamestown.
27
Day 3 Ancient Rome Legacies
The document provides instructions for a lesson on the legacies of Ancient Rome. Students will watch a video about life in Ancient Rome and participate in a gallery walk, taking notes on the legacies of Roman baths, roads, the Circus Maximus, the Forum, the Pantheon, the Colosseum, and aqueducts. They will then debate which legacy was the most important and discuss how the legacies of Ancient Rome have affected modern society.
Day 1 Athens and Sparta
This document provides information about Athens and Sparta, two major city-states in Ancient Greece. It discusses how their geography contributed to the development of distinct societies and governments. Athens developed a direct democracy where citizens voted on policies, while Sparta established an oligarchy ruled by a military elite. The document uses maps, pictures and questions to explore the differences between the more culturally-focused Athens versus the militaristic Sparta. Students are engaged through various individual and group activities to learn key similarities and differences between these influential Greek city-states.
