2.1 Identify energy forms, sources and transformations
| | | 2.1.1 | | use a variety of tools to measure the gain and loss of energy (e.g., thermometers, balances, colorimeters) | | 2.1.2 | | recognize that some materials conduct heat better than others (e.g., copper compared to sand) | | 2.1.3 | | describe how convection transfers heat energy | | 2.1.4 | | describe how radiation transfers heat energy | | 2.1.5 | | describe how conduction transfers heat energy | | 2.1.6 | | distinguish between stored energy (potential) and energy in motion (kinetic) | | 2.1.7 | | trace the flow of energy in a system (e.g., electricity in a circuit used to produce heat, light, sound on a magnetic field) |
