Chapter 12: Energy, Technology/ Engineering Learning Objectives: 12.1 Develop a working definition of energy 12.2 Explain relationships between energy and forces 12.3 Explain how energy transfer is related to potential energy, kinetic energy, and work 12.4 Describe how waves relate to energy 12.5 Identify properties of electrical, sound, light, and heat energy The flow of energy is central to Earth systems. The scientific and engineering communities expressed energy in a variety of ways. At its most basic, energy can be defined as the ability to do work or effect change. The transformation and transfer of energy enables us to harness energy to sustain life, move mountains, and run computers. Potential energy refers to objects, large or small, that are in a state of being able to release energy

Chapter 11: Matter and Motion Learning Objectives: 11.1 Explain how the Kinetic molecular theory of matter can be used to explain fundamental properties of matter 11.2 Describe distinctive attributes of chemical reactions 11.3 Provide examples for Newton's laws of motion 11.4 Explain how mass and distance relate to gravitational force Matter is defined as anything that occupies space and has mass. A physical change occurs when matter transitions from one state or phase to another. The kinetic molecular theory is used to explain a wide range of material change. A chemical change is a change in matter that results in the formation of a new substance. Matter exists in the form of elements, compounds, and mixtures. Atoms are made up of many smaller particles. Matter neither creates nor destroys it
