					Heat: The Transfer of Thermal Energy
I. Topic Area Investigating concepts of thermal energy transfer of various objects and relating thermal conductivities of these objects. II. Introductory Statement Various objects will be placed under a light source for a period of 3minutes. To conclude this activity, students will discuss the rate of temperature increase for each object and thus the thermal conductivities. III. Science Skills       IV. Collecting data Predicting Observing Measuring Recording data Interpreting data Math Skills Graphing Measuring          place both fingers in the container of warm water. Students will explain which finger gained energy from the warm water and which lost energy to the warm water. Students will record the temperature of the objects that have been sitting in the room. Students will predict which of the objects are good conductors and insulators of thermal energy. Students will test their predictions by placing each object underneath the light source for 3mins and record the temperature of each object. A graph of the findings will be created. Students will analyze their graph and draw conclusions and see if were correct. Students will place a penny underneath the light source for 3min. They will cover it with the foil and place the thermometer on top and record the temperature of the foil after one minute. Students will repeat the procedure replacing the aluminum foil with Styrofoam and recording the temperature after one minute. Students will describe how they would construct an efficient cooking pot using any of the materials investigated.

Materials          Light bulbs and socket Bucket (cold, warm and hot) Stopwatch Thermometer Metals (iron, aluminum) Plastic Di Wooden Blocks Styrofoam cup Pennies

VII.

What Students will do      Measure the temperature of the heated materials Record measurements in data table Graph the temperature for each material Determine which material has the highest thermal conductivity Describe how they would construct an efficient cooking pot based on their understanding of thermal conductivities

V.

Key Question “How is thermal energy transferred and how does it determine conductivity of a material?”

VI.

Procedure/Instruction  Students will place one finger in a container of hot water and one finger from the opposite hand in the container of cold water. Then,
