Elements and their combinations account for all the varied types of matter in the world. As a basis for understanding this concept: a. Students know that during chemical reactions the atoms in the reactants rearrange to form products with different properties. b. Students know all matter is made of atoms, which may combine to form molecules. c. Students know metals have properties in common, such as high electrical and thermal conductivity. Some metals, such as aluminum (Al), iron (Fe), nickel (Ni), copper (Cu), silver (Ag), and gold (Au), are pure elements; others, such as steel and brass, are composed of a combination of elemental metals. d. Students know that each element is made of one kind of atom and that the elements are organized in the periodic table by their chemical properties. e. Students know scientists have developed instruments that can create discrete images of atoms and molecules that show that the atoms and molecules often occur in well- ordered arrays. f. Students know differences in chemical and physical properties of substances are used to separate mixtures and identify compounds. g. Students know properties of solid, liquid, and gaseous substances, such as sugar (C 6 H 12 O 6 ), water (H 2 O), helium (He), oxygen ( O 2 ), nitrogen (N 2 ) , and carbon dioxide (CO 2 ) . h. Students know living organisms and most materials are composed of just a few elements. i. Students know the common properties of salts, such as sodium chloride (NaCl) Life Sciences 2. Plants and animals have structures for respiration, digestion, waste disposal, and transport of materials. As a basis for understanding this concept: a. Students know many multicellular organisms have specialized structures to support the transport of materials. b. Students know how blood circulates through the heart chambers, lungs, and body and how carbon dioxide (CO 2 ) and oxygen (O 2 ) are exchanged in the lungs and tissues. c. Students know the sequential steps of digestion and the roles of teeth and the mouth, esophagus, stomach, small intestine, large intestine, and colon in the function of the digestive system. d. Students know the role of the kidney in removing cellular waste from blood and converting it into urine, which is stored in the bladder. e. Students know how sugar, water, and minerals are transported in a vascular plant. f. Students know plants use carbon dioxide (CO 2 ) and energy from sunlight to build molecules of sugar and release oxygen. g. Students know plant and animal cells break down sugar to obtain energy, a process resulting in carbon dioxide (CO 2 ) and water (respiration). Earth Sciences 3. Water on Earth moves between the oceans and land through the processes of evaporation and condensation. As a basis for understanding this concept: a. Students know most of Earth’s water is present as salt water in the oceans, which cover most of Earth’s surface. b. Students know when liquid water evaporates, it turns into water vapor in the air and can reappear as a liquid when cooled or as a solid if cooled below the freezing point of water. c. Students know water vapor in the air moves from one place to another and can form fog or clouds, which are tiny droplets of water or ice, and can fall to Earth as rain, hail, sleet, or snow. d. Students know that the amount of fresh water located in rivers, lakes, under-ground sources, and glaciers is limited and that its availability can be extended by recycling and decreasing the use of water. e. Students know the origin of the water used by their local communities. 4. Energy from the Sun heats Earth unevenly, causing air movements that result in changing weather patterns. As a basis for understanding this concept: a. Students know uneven heating of Earth causes air movements (convection currents). b. Students know the influence that the ocean has on the weather and the role that the water cycle plays in weather patterns. c. Students know the causes and effects of different types of severe weather. d. Students know how to use weather maps and data to predict local weather and know that weather forecasts depend on many variables. e. Students know that the Earth’s atmosphere exerts a pressure that decreases with distance above Earth’s surface and that at any point it exerts this pressure equally in all directions. 5. The solar system consists of planets and other bodies that orbit the Sun in predictable paths. As a basis for understanding this concept: a. Students know the Sun, an average star, is the central and largest body in the solar system and is composed primarily of hydrogen and helium. b. Students know the solar system includes the planet Earth, the Moon, the Sun, eight other planets and their satellites, and smaller objects, such as asteroids and comets. c. Students know the path of a planet around the Sun is due to the gravitational attraction between the Sun and the planet.

An element is a simple substance. Elements are put together to make all other substances. Some common elements are carbon, aluminum, oxygen, and iron. Elements are different from one another. For example, some are heavy. Others are light. Elements are made of tiny particles called atoms. An atom is the smallest particle that has the properties of an element. In fact, atoms are too small to see. That’s because an atom is less than a billionth of an inch in size. Each element has one kind of atom. All atoms in an element are alike. Matter is always changing. Liquid water can freeze into solid ice, for example. This change is called a physical change. The ice is not a new substance. It is just water in a solid form. Chemical reactions are different. In a chemical reaction, a new substance is made. It is the result of a chemical change.What the substance starts out as is called a reactant (ree • AK • tuhnt). The new substance is called a product . To show that products come from reactants, we write it as What Aluminum Is Made Of reactants products aluminum foil To get an atom of aluminum, you need a piece of foil that is very small. 6 A common example of a chemical reaction is the formation of carbon dioxide (CO 2 ). The diagram below shows how carbon (C) atoms and oxygen (O 2 ) molecules can combine. A molecule is a tiny particle made of one or more atoms. The reactants are carbon and oxygen. They combine into a product, carbon dioxide. The total mass, or amount, of the products does not change. They have the same mass as the reactants before the chemical reaction. The total number of atoms also remained the same. For instance, three atoms are in the reactants and in the products shown below. Atoms simply make new combinations. The new arrangement of atoms gives the products new and different properties. Atoms do not increase during chemical changes. They do not decrease, either. 16 aluminum atoms C carbon O 2 oxygen CO 2 carbon dioxide + What Carbon Dioxide Is Made Of 7 S ometimes Maelo Cordova plays with modeling clay. Other times he tries out paint for dolls or races tiny cars. Cordova is a chemist. He uses chemistry to make toys. As a kid in Puerto Rico, Cordova asked questions like, “How can I mix cleaning products to get out spots?” He loved learning how substances combine to make new stuff. This process is called a chemical reaction. A chemical reaction occurs when two or more substances combine to make a new substance. The starting substances are called reactants. When they are mixed, the new substances are called products. Cordova won a top science award. Then he studied chemistry in college. He now works for a big toy company. At work, Cordova mixes chemicals and performs experiments. For one project, he was asked to make icky, sticky slime. The goo came out too hard, but he saved it. He later turned his mistake into a new invention, flubber. Says Cordova, “In science, you never throw anything away.” His next mistake may turn out to be even more fun. For one man, mixing chemistry and clay leads to new discoveries—toys!

An element is a substance that contains only one kind of atom. It can’t be broken down into a simpler substance. A compound is made by combining two or more elements chemically. One compound is sodium chloride. It is a combination of the elements sodium and chlorine. You know it as table salt. Charles D. Winters/Photo Researchers, Inc. Great Chemistry This table lists some famous chemists and their achievements. Light Up the Night Some chemical reactions produce light. One example is a toy you may have seen. It is a plastic tube that glows in the dark. The tube is filled with a liquid substance. When you bend the tube, a small container inside it breaks. This causes a chemical reaction between the two substances. One product of the reaction is light. The light makes the dye in the tube glow in the dark. Photolibrary.com pty.
