Strand 8.1: MATTER AND ENERGY INTERACT IN THE PHYSICAL WORLD

The physical world is made of atoms and molecules. Even large objects can be viewed as a combination of small particles. Energy causes particles to move and interact physically or chemically. Those interactions create a variety of substances. As molecules undergo a chemical or physical change, the number of atoms in that system remains constant. Humans use energy to refine natural resources into synthetic materials.

Standard 8.1.1

Develop a model to describe the scale and proportion of atoms and molecules. Emphasize developing atomic models of elements and their numbers of protons, neutrons, and electrons, as well as models of simple molecules. Topics like valence electrons, bond energy, ionic complexes, ions, and isotopes will be introduced at the high school level. (PS1.A)

• 8.1 Chemical Reactions Lesson Plan & Resources
  In this lesson, students observe changes in matter and develop models of chemical equations in order to develop a definition for chemical reactions, identify patterns of change that indicate that a chemical reaction has taken place, and explain the relationship between reactants and products at a molecular level. The lesson plan includes an 8-day lesson plan, Google Slides presentation, student reading, and lab/workshop instructions.
