CCSD | Department of Instructional Support | CCSS 2014 SC Science Academic Standards and Performance Indicators Curriculum Map for Science | Physics Unit:Heat Transfer (H.P.3C) Standard: H.P.3 The student will demonstrate an understanding of how the interactions among objects can be explained and predicted using the concept of the conservation of energy. Conceptual Understanding: This unit is a mixture of conceptual (Laws of Thermodynamics, 3 modes of heat transfer, thermal equilibrium, Earth’s heat balance) and mathematical (using the specific heat equation and the heat transfer coefficient equation). Important to Note: All files referred to are on the websitehttp://ccsdphysics.weebly.com/organized by unit, except for tests. This is a short unit. Key concepts may be incorporated into the Power Plant Project which is a performance assessment at the end of the Power and Magnetism material. Unit Engagement/Anchor Activity Suggestions A short reading guide to define terms and questions about heat transfer is an appropriate introduction. Formative Assessment Opportunities Standard Assessment items Problem solving with specific heat equation and heat transfer equation PhET Greenhouse Effect Analysis H.P.3C1, H.P.3C2 H.P.3C3 Summative Assessment Opportunities Standard H.P.3C.1, H.P.3C.2 H.P.3C.1, H.P.3C.3 Assessment Items Conduct a lab OR Analyze data from a lab already conducted Incorporate heat transfer into Power Plant Project (in E & M unit) CCSD | Department of Instructional Support | CCSS 2014 SC Science Academic Standards and Performance Indicators Curriculum Map for Science | Physics Investigations and Resources 2014 science Focus question performance indicators H.P.3C.1 Plan and What is the conduct controlled difference scientific between investigations to temperature determine the and heat? variables that Why do affect the rate of double-paned heat transfer windows between two reduce energy objects consumption? What heat transfer mechanisms apply when cooking food? H.P.3C.2 What materials are Analyze and good or poor interpret data to conductors of describe the heat? thermal conductivity of different materials. Activity Description 5 E Cycle Expected outcome – learning goal Define conduction, convection and radiation. Apply those definitions to scenarios. Correctly identify which heat transfer process is involved in various situations. Use Ice Melting Blocks (one is aluminum, one is wood). Ask students to feel the blocks and predict which one will melt a block of ice first. Document observations. Hypothesize what other factors affect the rate of heat transfer. Conduct a lab if you have the equipment OR analyze data and make graphs/mathematical models to determine the k-value for various materials. Solve problems using the rate of heat transfer equation and specific heat equation. Contrast heat and temperature. Contrast insulator and conductor Resource – instructional material (includes specific pgs, chapters, lessons, etc. Holt Physics Chapter 9 Sections 1 and 2 Vocabulary (tier 2 and 3) Heat Transfer Bellwork.doc Laws of thermodynamics Ice Melting Blocks from Flinn http://www.youtube.com/watch?v= pQ-yrGp8sfQ Convection demonstration (fish tank and food coloring) Apply the zeroth law http://www.youtube.com/watch?v= of thermodynamics 7xWWowXtuvA to the process of conduction.

Use the Greenhouse PhET to study Explain how the the energy balance of the Earth and Sun’s answer a set of questions. electromagnetic radiation is absorbed and lowerenergy IR radiation (heat) is emitted by the Earth Explain how this IR radiation is absorbed by only certain molecules in the atmosphere (CO2, CH4) and then IR is emitted back into the atmosphere http://phet.colorado.edu/en/simula tion/greenhouse Heat Transfer Basics and PhET MiniLab.doc
