Chemical Reactions
Age 12-14: Concept 1 - Semester 1: Unit 2

Learn about the nature of atoms and elements in this unit on the chemical and physical properties of matter. Find out how chemical reactions alter substances, and discover the names of important chemical processes like combustion and oxidation. This unit also explains how the pH levels of acids and bases are measured, and it defines the main terms used to describe the physical and chemical properties of matter. You will learn how scientific arguments are created using claims and evidence, and you will end the unit by exploring the difference between synthetic and natural substances.

For the final project, you will be able to practice your ability to evaluate evidence and make value judgments about the nature of chemical substances. The project asks you to play the role of a drug-company CEO who must analyze a pharmaceutical drug and make a case to investors for why the drug should or should not be produced.

Summary of Skills

Moving Beyond the Page is based on state and national standards. These standards are covered in this unit.
  • Demonstrate that new substances can be made when two or more substances are chemically combined and compare the properties of the new substances to the original substances. (Science)
  • Demonstrate that substances may react chemically to form new substances. (Science)
  • Describe and measure quantities related to chemical/physical changes within a system: gas production and precipitates. (Science)
  • Describe and measure quantities related to chemical/physical changes within a system: temperature, volume, and mass. (Science)
  • Describe risks and benefits of chemicals including medicines, food preservatives, crop yield, and sanitation. (Science)
  • Describe the suitability of materials for use in technological design: electrical conductivity, magnetism, and solubility. (Science)
  • Identify substances based on characteristic physical properties such as density, chemical reactivity, and specific heat. (Science)
  • Identify that physical and chemical properties influence the development and application of everyday materials such as cooking surfaces, insulation, adhesives, and plastics. (Science)
  • Interpret information on the periodic table to understand that physical properties are used to group elements. (Science)
  • Know chemical reactions usually liberate heat or absorb heat. (Science)
  • Know how to determine whether a solution is acidic, basic, or neutral. (Science)
  • Know that chemical and physical properties are related to chemical/physical changes within a system. (Science)
  • Know that chemical reactions are processes in which atoms are rearranged into different combinations of molecules. (Science)
  • Know that substances have physical and chemical properties. (Science)
  • Know that the idea of atoms explains the conservation of matter: in chemical reactions the number of atoms stays the same no matter how they are arranged, so their total mass stays the same. (Science)
  • Knows that substances have chemical and physical properties. (Science)
  • Recognize that compounds made of the same elements will have the same characteristics regardless of location. (Science)
  • Recognize the importance of formulas and equations to express what happens in a chemical reaction. (Science)
  • Understand that both naturally occurring and synthetic substances are chemicals. (Science)
  • Understand that chemical reactions are processes in which atoms are rearranged into different combinations of molecules. (Science)
  • Understand that matter is composed of atoms. (Science)
  • Understand that physical processes in which a material changes are not the result of a chemical reaction. (Science)
