| An example of _____ transfer by conduction would be a metal spoon getting hot in a bowl of soup. | Heat |
| TRUE or FALSE While seated next to a camp fire, a person begins to feel the warmth of the fire. The energy is transferred form the fire to the person by radiation. | True |
| In a diagram of a _____ with the bulb glowing shows the energy changing as it moves from inside the battery, along the wires, and through the light bulb. This is an example of chemical to electrical to light. | Circuit |
| TRUE or FALSE An example of conduction is heat moving from a clothes iron to a shirt. | True |
| The tools most useful in an experiment measuring the rate of transfer of thermal energy in four different liquids would be _____ plate, beakers, and thermometers. | Hot |

| When a saucer sits below a coffee cup it becomes _____ after coffee is poured into the cup. Energy transferred from the cup to the saucer by conduction. | Warmer |
| TRUE or FALSE Thermal energy transferred by conduction is accomplished when heat moves from a warmer object to a cooler one by coming in dir4ect physical contact with it. | True |
| Renewable resources are _____ by natural means in a shorter period of time compared to fossil fuels. | replaceable |
| TRUE or FALSE Carbon is considered an element, while carbon dioxide is considered a compound. This is because carbon dioxide is a gas at room temperature and useful to human beings. | False |

| TRUE or FALSE When a large steel block (#1) is stacked over three smaller steel blocks (#2 – 4) the heat will transferred by conduction from the two blocks on the bottom sitting next to each other. | True |
| An egg is boiled in a pot of water on the stove. Heat is transferred from the stove to the pot directly. Heat is also transferred from the pot to the egg, carried through the water. This is an example of ______ and convection. | Conduction |
| TRUE or FALSE Water at 30 degrees Celsius was poured into four different containers. The temperature of the water was recorded after 15 minutes. The container with the temperature least heat lost is the most effective at preventing heat loss. | True |
