Learning Outcomes:

● state that the SI unit of temperature is kelvin (K)

● explain the transfer of heat energy through conduction, convection, and radiation

● describe some effects and applications of expansion and contraction in everyday life

● show an understanding that the rate of heat energy loss or gain by a body through radiation is affected by the

(i) colour and texture of the surface

(ii) surface temperature

● explain applications of transfer of heat energy through conduction and convection (e.g., in cooling, heating and insulation)

● explain applications of transfer of heat energy through radiation (e.g., radiant heaters, solar radiation)

● infer that generally, solids, liquids, and gases expand when heat energy is absorbed and contract when heat energy is given out

● infer that thermal expansion results in a change in volume, and therefore the density of the substance

● infer from experiments that different materials have different rates of heat energy transfer

● show an awareness of the various proposed causes (man-made and natural) of climatic change (e.g., global warming)
