Types of Heat Transfer• Conduction: Heat transfer through solids by atom
to atom collision; example: pot on stove, hold metal bar over campfire.
• Convection: Heat transfer through fluids (liquids, gases) due to differences in density (convection cell)– Warm: less dense, rises (hot air balloon)– Cold: more dense, sinks– Example: atmospheric circulation (winds,
• Radiation: Heat transfer through space. Example: tanning by sun’s radiation, heat (infrared rays) from fireplace, campfire, stove.
Heat Transfer: movement of energy from place to place.

FRIDAY YOU GET:
You are given a blank data table to collect your data and blank graph paper to plot your data. The graph will be a double line graph (1st line = water; 2nd line = soil) with one axis temperature and the other axis time. You are given 20 minutes to collect your heating and cooling data for soil (land) and water.
You will be given 5 minutes to discuss and set up your soil versus water experiment. We will start at Time = 0, record the temperature. Then I will start the stopwatch on the smartboard and every minute I will announce the time. You will record your temperature & time data. At 20 minutes, the experiment is over. Plot your results and start the lab write up.
READY?
FRIDAY’S LAB
DATA TABLETEMPERATURE (LIGHT ON) - HEATING TEMPERATURE (LIGHT OFF) - COOLING
• Land (sand): heats up and cools _______• Water (ocean): heats up and cools ______• Dark: heats up fast (absorbs heat energy)• Light: cools (reflects heat energy)• Smooth surfaces: cools (reflects heat
