Heating+solids

8I Heat transfer

=Heating solids=

List some examples of heat conductors and insulators. Explain conduction using the particle method. Explain why some solids are better conductors than others. Explain why solids expand when they are heated.
 * Objectives (what you will learn this lesson)**


 * Starter**
 * Review completed homework
 * How much do you know about particle theory? Complete the card match below (activity #1)

> media type="file" key="ES8_Ib122_12ani.swf" width="640" height="480" > - place two different cups (made out of different materials) on a desk, put a thermometer in each cup > - pour boiling water into each cup > - measure the temperature at the start and every minute for five minutes > - discuss which cup is the best insulator > - take notes (for use later) on why this was not a fair test and how it could be improved. > - complete the worksheet on which looks at analysing the results from a similar investigation > - **it is likely (check with your teacher) that you will be assessed on your investigation planning skills by designing your own investigation into insulation.**
