The atom is the smallest piece of matter and is made up of protons, neutrons, and electrons. Protons and neutrons are packed tightly together in the nucleus at the center of the atom, which contains most of its mass. Electrons have a negative charge and orbit outside the nucleus. Most atoms contain the same number of protons and electrons, so the charges cancel out and atoms as a whole are electrically neutral.

Basics of Matter
Matter is anything that takes up space and has mass. All matter is made up of tiny particles called atoms. Atoms are the smallest unit of matter and are made of protons, neutrons, and electrons. Atoms can combine to form molecules or crystalline structures, determining the state of matter. The four fundamental states of matter are solids, liquids, gases, and plasma, which are distinguished by how tightly or loosely packed the atoms/molecules are and how much they move. Changes between these states occur at specific temperature and pressure points for each substance.
What is a mineral
Minerals are naturally occurring substances that make up rocks and have distinct internal structures. Over 2000 minerals have been identified, though only a few make up most rocks. The physical and chemical conditions during formation determine a mineral's properties like color, hardness, crystal structure, luster and density. Minerals are classified as metallic, which include ferrous, non-ferrous and precious metals, or non-metallic like mica, salt and limestone. Energy minerals used as fuels include coal, petroleum and natural gas.

Concept Map
Flora is boiling water on the stove. She turns the dial up to high, causing the water to boil vigorously with large, quickly forming bubbles. She then turns the dial down to low, causing the water to boil gently with smaller, slowly forming bubbles. Flora wonders if the boiling temperature changes with the dial settings. The correct answer is C - the boiling temperature remains the same at 100 degrees Celsius regardless of the dial setting.
Heat capacity
Mia and Devon are having a summer party and need to make two sizes of ice. They wonder if the temperature at which water freezes is affected by the size of the ice. Small ice cubes freeze at a lower temperature than large blocks of ice. This is because it takes more energy to freeze a larger volume of water, so large blocks of ice freeze at a slightly higher temperature than small ice cubes.
Density Anomaly
This document discusses buoyancy, density, and why ice floats. It explains that ice is less dense than water due to the formation of hydrogen bonds between water molecules that cause water to expand when it freezes. As a result, the buoyant force on ice is greater than its weight, causing ice to float on water.
Buoyancy
The document compares two solid cubes made of the same material but different sizes - one is large and one is small. It asks which statement about the density of the cubes is true. The correct statement is that the density of the larger cube is the same as the density of the smaller cube, because density is a property of the material and does not change with the size of the object.
Water
Water is a polar covalent compound composed of two hydrogen atoms and one oxygen atom. The electrons in the covalent bonds are shared unequally, with the hydrogen side being partially positive and the oxygen side being partially negative. This gives water molecules a polar nature. Water exhibits both cohesion, the attraction of water molecules to one another, and adhesion, the attraction of water molecules to other substances. Due to its high surface tension, water forms a "skin" on its surface that requires a force to break. When placed in a glass, the water curves up the sides due to surface tension forming a meniscus.
Friction
The document provides an assignment to investigate the impact of fertilizer amounts on plant growth. To properly conduct this investigation, the following factors would need to be controlled: the amount of water given to each plant, keeping track of the fertilizer amounts given to each plant, starting with plants of the same size, and keeping all plants in a similar location. Variables like the amount of fertilizer and location of the plants would need to be manipulated, while the dependent variable of plant height would be measured.
Scientific Method
The document outlines the key steps of the scientific method, which are: 1) identifying a problem or question, 2) researching existing knowledge, 3) forming a hypothesis, 4) testing the hypothesis through experimentation, 5) recording and studying the data, 6) forming a conclusion, and 7) communicating the results. It also defines key terms used in the scientific method, such as hypothesis, variables, control, and constant.

Metamorphic rocks form deep within the Earth under conditions of great heat and pressure, partially melting existing rocks like igneous or sedimentary stone. Metamorphic rocks can contain fossils from their original parent rock and form in place from the alteration of other types of rock under high temperature and pressure conditions within the Earth's crust. Common examples include marble.
Metamorphic Rocks
The document discusses different types of sedimentary and metamorphic rocks. It states that sandstone forms from cementation, conglomerate forms from compaction, coal forms from organic material, and limestone forms from organic material or liquid solutions. Sedimentary rocks can contain fossils. Metamorphic rocks form from existing rocks undergoing changes from heat and pressure, and examples given are shale transforming to slate and limestone transforming to marble.
Sedimentary Rocks
This document discusses the three main types of rocks: igneous, sedimentary, and metamorphic. It explains that igneous rocks form from cooled magma and have large crystals if they cool slowly, small crystals if they cool fast, and no crystals if they cool extremely fast. Sedimentary rocks form from pieces of other rocks, once-living things, or liquid solutions that harden over time. Metamorphic rocks form from intense heat or pressure that transforms existing rocks.
Igneous Rocks
The document discusses properties of minerals including that minerals are inorganic, have crystal structures, and can be identified by properties like hardness, streak, cleavage, and crystal form. Halite is identified as having cubic crystal formation and displaying fracture when it breaks.
