General Lesson Information
 Lesson Plan ID: 548 Title: Energy and Work Amusement Park Style Overview/Annotation: This is a lesson presenting energy and work. It covers: types of energy, forms of energy, work, law of conservation of energy, and renewable and nonrenewable energy sources. In the activities section, one will find links to Internet sites that explore concepts of energy and work. Interactive labs are also included in this lesson. The lesson can serve as a student-led or teacher-led lesson. It gives a brief statement of facts; therefore, the teacher must provide expansions, if needed. The expansions could come from the Internet sites since many of them go into more detail about the concepts. The teacher will also be expected to supply some form of assessment for the lesson.

NAEP Framework NAEP Statement:: P12.17: The motion of an object can be described by its position and velocity as functions of time and by its average speed and average acceleration during intervals of time. Unpacked Content Scientific And Engineering Practices:Analyzing and Interpreting DataCrosscutting Concepts: Cause and EffectDisciplinary Core Idea: Motion and Stability: Forces and InteractionsEvidence Of Student Attainment:Students: Analyze (break into parts) data for one-dimensional motion applying basic concepts of distance, displacement, speed, velocity, and acceleration.

A particle moving in a straight line undergoes one dimensional motion. A particle moving along a curved path in a plane has two dimensional motion.Skills:Students are able to: Create graphs from sets of data points. Identify distance and displacement as a scalar/ vector pair. Identify speed and velocity as a scalar/ vector pair. Describe motion mathematically in terms of an object's change of position, distance traveled, and displacement. Apply concepts of average speed and average velocity to solve conceptual and quantitative problems. Explain velocity as a relationship between displacement and time. (Δd=vΔt) Explain acceleration as a relationship between velocity and time. (a=Δv/Δt) Use graphical analysis to understand conceptual trends in displacement, velocity, acceleration, and time. Use graphical analysis to solve for displacement, velocity, acceleration, and time. Calculate velocity and acceleration from displacement vs. time graphs.Understanding:Students understand that: Motion graphs (displacement vs. time, velocity vs. time, and acceleration vs. time) for one- and two- dimensional motion may be used to derive (conceptual and mathematical) relationships of motion.AMSTI Resources:ASIM Physics Module: Analyzing Motion Using Graphs; Run for It; Batter Up Science SC2015 (2015) Grade: 9-12 Physical Science 8 ) Apply Newton's laws to predict the resulting motion of a system by constructing force diagrams that identify the external forces acting on the system, including friction (e.g., a book on a table, an object being pushed across a floor, an accelerating car). Unpacked Content Scientific And Engineering Practices:Developing and Using ModelsCrosscutting Concepts: Systems and System ModelsDisciplinary Core Idea: Motion and Stability: Forces and InteractionsEvidence Of Student Attainment:Students: Predict the motion of a system by application of Newton's laws. Construct force diagrams. Identify external forces acting on a system.Teacher Vocabulary: Weight Mass Gravity Acceleration Velocity Terminal velocity Free fall Friction Static friction Rolling friction Fluid friction Inertia Force Balanced forces Unbalanced forces Net force Action-reaction pairs VectorsKnowledge:Students know: An object will remain at rest or in uniform motion unless acted on by an outside force. The velocity of an object changes when it is subjected to an external force. Gravity's acceleration is different on different planets. Air resistance is responsible for terminal velocity for objects in free fall. The property of inertia as related to mass. Forces must be unbalanced for an object to change its motion. Friction is a force that opposes motion.Skills:Students are able to: Organize data that represent the net force on an object (mass and acceleration) via tables and graphs. Construct force diagrams that identify all external forces acting on the system. Explain (conceptually and mathematically) the relationship between force, mass, and acceleration. (The greater the force on an object, the greater its change in motion but the same amount of force applied to an object with more mass will result in less acceleration.) Relate the difference between mass and weight. (Weight is a force dependent upon acceleration and mass is constant regardless of acceleration.) Calculate weight when given mass. (Fg=mg) Explain acceleration due to gravity as an example of uniformly changing velocity. (g=9.8 m/s2) Relate the presence of air resistance to the concept of terminal velocity of an object in free fall. Identify friction as a force that opposes motion of an object. Classify the frictional forces present in different situations. (Sofa resting on the floor is static friction. A box pushed across the floor is sliding friction. A ball rolling across the floor is rolling friction. A boat moving through a river is fluid friction. An object in free-fall is fluid friction.) Explain the property of inertia as related to mass. (An object at rest or at constant speed in a straight line will remain in that state unless acted upon by a force causing an unbalanced net force.) Explain balanced and unbalanced forces mathematically and graphically with respect to acceleration to establish the relationship between net force, acceleration, and mass.Understanding:Students understand that: The motion of a system may be predicted by applying Newton's laws of motion to force diagrams that identify all external forces acting on the system. Forces acting on an object affect the motion of that object.AMSTI Resources:ASIM Physics Module: Force Diagrams; Horizontal Friction Science SC2015 (2015) Grade: 9-12 Physical Science 11 ) Design and conduct investigations to verify the law of conservation of energy, including transformations of potential energy, kinetic energy, thermal energy, and the effect of any work performed on or by the system. NAEP Framework NAEP Statement:: P12.13: The potential energy of an object on Earth's surface is increased when the object's position is changed from one closer to Earth's surface to one farther from Earth's surface. NAEP Statement:: P12.16: Total energy is conserved in a closed system. NAEP Statement:: P12.9: Energy may be transferred from one object to another during collisions.

Properties of materials cause different materials to absorb and release energy differently. Conduction, convection, and radiation are methods of energy transfer. Energy can be conserved when there are changes in potential, kinetic, or heat energy.Skills:Students are able to: Compare thermal energy, heat, and temperature. Compare scenarios in which work is done and explain the differences in magnitude of work done using the relationship W=FΔd Infer the ability of various materials to absorb or release thermal energy in order to relate mass, specific heat capacity and temperature of materials to the amount of heat transferred (q=mCΔT). Relate phase changes to latent heat that changes the potential energy of particles while the average kinetic energy of particles (temperature) remains the same. Compare conduction, convection, and radiation as methods of energy transfer. Exemplify the relationships between kinetic energy, potential energy, and heat to illustrate that total energy is conserved in mechanical systems such as a pendulum, roller coaster, carts/balls on ramps. Relate types of friction in a system to the transformation of mechanical energy to heat. Explain scenarios in which work is done identifying the force, displacement, and energy transfer. (When work is done on an object, the result is an increase in its energy and is accompanied by a decrease in energy elsewhere.)Understanding:Students understand that: Conservation of energy means that the total change of energy in any system is always equal to the total energy transferred into or out of the system.AMSTI Resources:ASIM Physics Module: Bouncy; Ball Energy and Work; Energy and Power Science SC2015 (2015) Grade: 9-12 Physics 1 ) Investigate and analyze, based on evidence obtained through observation or experimental design, the motion of an object using both graphical and mathematical models (e.g., creating or interpreting graphs of position, velocity, and acceleration versus time graphs for one- and two-dimensional motion; solving problems using kinematic equations for the case of constant acceleration) that may include descriptors such as position, distance traveled, displacement, speed, velocity, and acceleration. NAEP Framework NAEP Statement:: P12.17: The motion of an object can be described by its position and velocity as functions of time and by its average speed and average acceleration during intervals of time. NAEP Statement:: P12.19: The motion of an object changes only when a net force is applied. NAEP Statement:: P12.22: Gravitation is a universal attractive force that each mass exerts on any other mass. The strength of the gravitational force between two masses is proportional to the masses and inversely proportional to the square of the distance between them.
