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.
Keywords: matter, energy, atoms, molecules, energy, chemical reaction, properties of matter,
- Develop a model to describe the scale and proportion of atoms and molecules.
- Obtain information about various properties of matter, evaluate how different materials’ properties allow them to be used for particular functions in society, and communicate your findings. Emphasize general properties of matter.
- Plan and conduct an investigation and then analyze and interpret the data to identify patterns in changes in a substance’s properties to determine whether a chemical reaction has occurred.
- Obtain and evaluate information to describe how synthetic materials come from natural resources, what their functions are, and how society uses these new materials.
- Develop a model that uses computational thinking to illustrate cause and effect relationships in particle motion, temperature, density, and state of a pure substance when heat energy is added or removed.
- Develop a model to describe how the total number of atoms does not change in a chemical reaction, indicating that matter is conserved.
- Design, construct, and test a device that can affect the rate of a phase change. Compare and identify the best characteristics of competing devices and modify them based on data analysis to improve the device to better meet the criteria for success.
