Heat Standards:S3P1. Students will investigate how heat is produced and the effects of heating and cooling, and will understand a change in temperature indicates a change in heat. a. Categorize ways to produce heat energy such as burning, rubbing (friction), and mixing one thing with another. b. Investigate how insulation affects heating and cooling. c. Investigate the transfer of heat energy from the sun to various materials. d. Use thermometers to measure the changes in temperatures of water samples (hot, warm, cold) over time.
The movement of thermal energy is called what? HEAT
Look at the following slides Look at the following slides. Determine if the following objects are hot or cold.
Hot Cold
Look at the following slides Look at the following slides. Determine if the following objects are insulators or conductors.
Insulator Conductor
Rubbing our hands together creates heat. What kind? FRICTION
In what direction does heat flow? Hot to Cold
Decide if each object is a SOURCE of heat Go from left to right. Yes Yes NO NO
Think about our experiment. The bowl of hot water, the 3 spoons Think about our experiment. The bowl of hot water, the 3 spoons. (Metal, Wooden, Plastic) See next slide.
Which one does NOT get hot? Which one melts? PLASTIC Which one does NOT get hot? WOODEN Which one gets hot? METAL
Tell the temperature on each thermometer
