It includes exercises for students to identify multiples and write multiples between given numbers. The document also introduces the concept of consecutive multiples as multiples that follow one another numerically.
division
Division is the process of splitting a quantity into equal parts or groups. The amount being divided is called the dividend, while the number it is being divided by is the divisor. To perform division, the divisor is subtracted from the dividend repeatedly until the remainder is zero. The number of times the divisor is subtracted is the quotient. Common word problems involving division use language like "share", "each", and "equal groups". Strategies for solving division problems include repeated addition, repeated subtraction, writing the division as a symbol, or drawing pictures to represent sharing into groups.

Metamorphic rocks
Metamorphic rocks are rocks that have changed from their original form due to heat, pressure, and fluids. There are two main types of metamorphism - contact metamorphism which occurs in small local areas, and regional metamorphism which affects large areas. Metamorphic rocks form through heat from the mantle, pressure from overlying rock layers, and fluids which can change a rock's chemistry and minerals. Metamorphic rocks are classified as either foliated (layered) such as gneiss and slate, or nonfoliated (nonlayered) such as marble and quartzite.
Rocks rock!
Rocks can have varying properties and are not always hard, solid, natural, or composed solely of minerals as initially thought. Rocks are classified based on their formation process, with the main types being igneous (formed from cooling magma), metamorphic (formed from existing rocks undergoing heat and pressure), and sedimentary (formed from compression of sediments over time). The document serves to dispel preconceptions about rocks and introduce how they are scientifically classified according to their formation.

Earth science overview
This document provides an overview of the curriculum for an Earth and Space science class. The year will be divided into four parts - geology, oceanography, meteorology, and astronomy. Geology will cover topics like minerals, rocks, fossils and plate tectonics. Oceanography will explore the ocean environment including waves, currents, and marine life. Meteorology will study the atmosphere, weather patterns, and severe weather. Finally, astronomy will examine objects in our solar system and beyond, such as stars, galaxies, and nebulae.
Observations and inferences
The document discusses the differences between observations and inferences. Observations are what can be seen or noticed directly from a drawing or situation, while inferences are conclusions or explanations that are formed based on observations but cannot be directly observed. The document prompts the reader to write down observations and inferences based on drawings or stories in order to understand how inferences can differ between people even when based on the same observations.
Relationships in a Food Web
The document discusses the relationships between organisms in a food web. It defines producers as organisms that make their own food, mostly plants. Consumers must find their own food and include all animals. Decomposers like worms and fungi break down dead and decaying matter. Consumers are classified as herbivores that eat only plants, carnivores that eat only meat, and omnivores that eat both plants and meat. A food chain shows the transfer of energy from producers to consumers as one organism eats another. A food web depicts overlapping food chains and shows how all animals in a community obtain food. An energy pyramid illustrates the decreasing amount of energy at each trophic level in a food web.
Relationships in Ecosystems
This document discusses key relationships in ecosystems, including populations, competition, limiting factors, carrying capacity, symbiosis, mutualism, commensalism, parasitism, predator-prey relationships, and cooperation. Populations of the same species compete for resources like food and space within an ecosystem. Symbiosis describes close species interactions like mutualism where both benefit, commensalism where one benefits and the other is unaffected, and parasitism where one benefits at the other's expense. Predator-prey relationships involve predators consuming other organisms as prey. Cooperation occurs when organisms work together for common goals.
Earth moon system
The document summarizes various topics relating to Earth's seasons, phases of the moon, eclipses, and tides. It explains that Earth's rotation causes day and night, while its revolution around the sun causes years. It describes how the tilt of the Earth on its axis causes seasons. It also discusses the phases of the moon and how they are caused by the relative positions of the Earth, moon, and sun. Lunar and solar eclipses occur when one celestial body passes in front of another, blocking light. Tides are caused by the gravitational pull of the moon and sun and change approximately every six hours.
Moon Formation and Structure
The document discusses evidence that supports the collision theory of lunar formation, in which an object the size of Mars collided with Earth, ejecting material that formed the moon. Key evidence includes the moon's similar surface composition to Earth's crust and mantle, the lack of an atmosphere due to the force of the impact, and similar oxygen atoms between Earth and the moon that are different from other celestial objects. The document also provides an overview of Apollo missions to the moon and features observed like maria, highlands, and craters.
Storms
Hurricanes form over warm ocean waters and require specific conditions including warm temperatures, low pressure, high humidity, and the Coriolis effect. They can produce dangerous storm surges that are the most damaging part of a hurricane. Thunderstorms form from cumulus clouds and can produce tornadoes, hail, lightning and heavy rain. Flash floods occur when rainwater cannot drain quickly from an area, while river flooding happens when a river overflows its banks due to heavy rainfall.
Salt water notes with blanks(ch13, 14)andie
The document summarizes key aspects of Earth's hydrosphere including ocean motions, tides, ocean chemistry, ocean currents, ocean zones, and life in the ocean. It discusses how waves are formed by wind, differences in water density and pressure with depth, and how tides are caused by the gravitational pull of the moon and sun. It also outlines the salinity and salt composition of ocean water, factors influencing ocean currents like wind and the Coriolis effect, and different features of the ocean floor including the continental shelf, slope, and abyssal plains.

Soil horizons
This document describes the typical horizons found in a mature soil profile. It explains that a mature soil profile contains O, A, B, and C horizons. The O horizon contains organic material like leaves and twigs. The A horizon is dark colored due to mixing with humus. The B horizon is the subsoil, containing materials leached from above. The C horizon contains partially weathered parent material and mineral particles.
Soil
Soil is made up of weathered rock and decayed organic matter that provides nutrients for most plants to grow. It forms over time as bedrock is broken down by weathering processes like water and wind, and as organisms like bacteria and fungi break down bedrock and organic material. Soil is important because it supports the growth of plants that produce food and provide habitat for animals - without soil, life on land would be very different.
Direct Variation
The document defines direct variation and provides examples of direct variation relationships. It explains that direct variation occurs when y varies directly with x, meaning y=kx where k is the constant of variation. As x increases or decreases, y also increases or decreases. The document provides examples of tables showing direct variation relationships and calculating the constant of variation k. It also shows how to use direct variation equations to solve word problems by finding the constant k and plugging values into y=kx. Finally, it discusses the graph of a direct variation relationship, noting it must pass through the origin.

The document summarizes key facts about the Milky Way galaxy and the universe:
1) A constellation is a group of stars that appear close together but are not actually physically close. Constellations help people navigate the night sky.
2) A light year is the distance light travels in one year, which is about 6 trillion miles. The closest star to our solar system, Proxima Centauri, is about 4 light years away.
3) Stars are classified by size, temperature, and stage of life. As stars age, they evolve through different stages on the Hertzsprung-Russell diagram until dying. Our Sun will become a red giant in about 5 billion years.
