In this experiment the radio meter spins when light hits it because of the thermal energy. This is because there are white and black colors on both sides of the vane. When air molecules hit the white side of the vane they produced a little push, but when they hit the black side of the vane, they push with a lot of force. This causes the vanes to turn. In other word, the radiant energy reaches the radiometer, the more thermal energy turns into motion energy and cause the vanes to spin (motion.) The solar panels in this experiment worked because of the photovoltaic cell (PV cells) that solar panels contain. These PV cells converted from radiant energy to electrical energy to motion energy. Therefore, the motor converted electrical energy to kinetic energy which caused the fan to spin. In the experiment the motor didn’t run when we covered half of the solar panel, but when we didn’t cover the solar panel, the motor worked. This is because the light was shining directly on the PV cells (more radiant energy hit the PV cells.) During this experiment the temperatures of the thermometers changed because of the light’s radiant energy is turned into thermal energy. When I placed the thermometer under the light, the temperature was increasing because the radiant energy is hitting it directly. Although, the temperature of the thermometer in the shade stayed the same because of the same amount of radiant energy hitting it, causing it to stay at the same temperature. So, in this experiment the radiant energy from the light turned into thermal energy. In this experiment we placed a glow toy in a pouch and one under the light. The glow toy that was placed under the light absorbed radiant energy and stores it because of the phosphor (zinc sulfide) that the glow toy contains. We found out that the glow toy that was placed in the bag didn’t glow because light didn’t hit the toy. Meaning the toy couldn’t store radiant energy. Although, the toy that was placed in the light, absorbed and stored radiant energy when it was left in the light. Overall, the glow toy placed in the light converted from chemical energy to radiant energy. For this experiment, we bent the metal hanger five times. By doing this, we used our kinetic energy to bend the hanger to create friction because the molecules of the metal bend faster. As the hanger builds friction it transforms into thermal energy (heat.) SO, the energy transformed from chemical (muscles stored chemical energy from the food you ate) to kinetic energy (motion from muscles in hands to bend hanger) to thermal energy in the hanger. The rubber band in this experiment was stretched to cause friction. The friction created the temperature of the rubber band to increase because when you stretched the rubber band, you put stress on the molecules and released heat. However, when the rubber band contracted the stress was removed and the molecules absorbed the heat. This means that the energy transformed from stored mechanical, to thermal energy, then back to mechanical energy. In this experiment the live wire is a nitinol wire that can return to its original form when placed in hot water because it contains nickel and titanium that expand differently. The nitinol wire can turn back in its original shape because its heat treated. As a result, the energy went from stored mechanical, to thermal (when it was placed in hot water) and then into motion energy (when wire turns into its original shape.) In this experiment, we placed a bi-metal bar over a candle causing it to heat up. The bi-metal bar contains two metals in it, stainless and nickel. Each of these metals expands at different rates when heated. As we continued heating the bar metal, the metal started to expand toward the nickel side. This is because the stainless steel in the bar expands quicker than the nickel causing the bar to bend toward the nickel side. So, the energy transformed from thermal energy to motion energy.
