Book Description

Energy, Force and Motion Forces and Motion • Recognize that a change in speed and direction is caused by a force and that a force is a push or a pull. • Recognize that the greater the force, the greater the change: the more massive the object, the smaller the change Energy and Work • Understand that energy has the ability to cause motion or to crate change, and that work is done when an object is moved a distance or when something undergoes a chemical change • Recognize different forms of energy and understand that when work is done, energy is often transformed between different forms of energy. Change of Motion • Understand that motion is the change in the position of an object which is caused by a force and that the heavier an object is, the more force is needed to make it move. • Recognize speed as a measure of motion an deb introduced to friction as a force which causes an object to slow down. Kinetic and Potential Energy • Define kinetic and potential energy, recognize examples of each, and explain how potential energy can be transformed into genetic energy and vice versa Ways and Object will Move • Understand the different ways that objects can move; side to side, back and forth, zigzag, straight line, round and round, etc. Transferring Energy • Explore ways in which energy can be transformed from one form to another Heat and Movement • Understand that heat is a form of energy and that energy causes motion. • Understand that heat moves from a warmer substance to a cooler substance and recognize that heat energy moves to and from some substances better than others
