Students will identify examples of three types of heat transfer.
Book 'The Hottest Boy Who Ever Lived' by Anna Fienberg; Overhead or chart of heat transfer examples listed in step 3; Science Journals or paper for students
Heat is transferred by conduction, convection, and radiation. Conduction is heat transfer by direct contact, like frying an egg. Convection is heat transfer by the movement of gases or liquids, like most home furnaces, clothes dryers, or car heaters. Radiation is the transfer of heat in waves through space, like the sun or a fire.
Use catagories to classify. Recognize the personal relevance of science in daily life. Respect the contributions of science to the quality of human life. Understand science concepts.
Show students a blow dryer, curling iron, and some item that was baked in the oven (cookie or bread). Ask students what these items have in common. (The curling iron and blow dryer produce heat The cookie was baked with heat. They all have something to do with heat.) Write conduction, convection, and radiation on the board. Explain the three types of heat tranfer to the students. As a class, decide which item is an example of each type of heat transfer. (Blow dryer- convection, curling iron-conduction, cookie or bread-baked by radiation.) Read 'The Hottest Boy Who Ever Lived' to the class and have students record examples of heat transfer in their science journals. After reading the book, have students share the examples of heat transfer they found in the story. Make a list on the board. Show the overhead or chart of examples from the book listed below. Compare to the class generated list.
Create a bulletin board of the types of heat transfer by having students cut out pictures from store ads. Divide a bulletin board into thirds and label the sections: conduction, convection, and radiation. Have students place the pictures in the correct section. (Conduction- frying pans, curling irons, irons, pots and pans, stoves, etc. Convection- clothes dryers, convection ovens, food dehydrators, portable heaters, etc. Radiation- microwaves, ovens, etc.)
Have students divide a piece of paper into thirds and label the sections: conduction, convection, and radiation. Ask students to write a least five examples of each type of heat transfer.
