Learning Target: Energy is the ability to do work and it comes in several forms.
Energy is the ability to do work
1. Recognize work as using force to move an object in the direction of the force
Energy comes in different forms (i.e. thermal [kinetic], electrical, nuclear, light [radiant/electromagnetic], mechanical [kinetic/potential], chemical [potential])
1. Define potential energy as stored energy 2. Define kinetic energy as motion 3. Recognize examples of different forms of energy
Learning Target: Energy transformations occur between different systems, andheat is often a byproduct within the system.
· Identify the different energy transformations that occur between different systems (e.g., chemical energy in battery converted to electricity in circuit converted to light and heat from a bulb) 1. Recognize the types of energy in a system 2. Diagram how energy changes form in a system
·Identify that, during an energy transformation, heat is often transferred from one object (system) to another because of a difference in temperature 1. Heat moves from warmer objects to cooler objects 2. Identify where heat is a byproduct of energy transformations in a system
· Recognize and describe how energy is not lost but conserved as it is transferred and transformed 1. Law of Conservation of Energy
· Recognize and describe how chemical energy is stored in chemical compounds (e.g., energy stored in and released from food molecules, batteries, nitrogen explosives, fireworks, organic fuels)
Learning Target: Thermal energy is transferred (moved) as heat using conduction, convection, and radiation when there is a difference in temperature between two things (until equilibrium).
· Identify thermal energy is transferred as heat from warmer objects to cooler objects until both reach the same temperature (equilibrium)
· Identify the type of materials that transfer energy by conduction, convection, and/or radiation
· Describe how heat is transferred by conduction, convection, and radiation, and classify examples of each
