How Did The Heat Lamp Affect Low Temperature

In this experiment, the Independent Variable was the heat lamp, and the dependent variable was the temperature of the soil, because the temperature varied based on whether the heat lamp was turned off or on, and whether there was extra water added or not. Our hypothesis was proven correct, because the dry soil’s temperature was hotter than the damp soil’s temperature when the heat lamp was on, but then it decreased when it turned off, while the damp soil’s temperature remained the same. This is because dry soil contains little moisture, so it warms quickly at day and becomes hot. The damp soil contains a lot of water, so it is unable to absorb the heat as quickly as the dry soil. However, when at night, dry soil cools really quickly, and radiates
Our hypothesis that to beaker with carbon dioxide’s temperature would be greater was proven correct, because the graph shows that the beaker with extra carbon dioxide in it had a greater temperature when the heat lamp was turned on. This is because carbon dioxide is defined as a greenhouse gas, and the definition of a greenhouse gas is a gas that traps heat in a certain area, and doesn’t let it escape. When the gas was placed in one of the beakers and the heat lamp was turned on, the rays of light were radiated into the soil, making it hotter. However, once the heat tried to escape, the carbon dioxide bounced it back, meaning that the beaker was absorbing heat and letting close to none of it escape. The beaker that didn’t contain carbon dioxide only heated up around one degree celsius, from 22.4 degrees celsius to 23.6 degrees celsius, while the beaker that contained carbon dioxide heated up from 23.3 degrees celsius to 26 degrees celsius. The beaker without carbon dioxide didn’t get hotter because while it absorbed just as much heat, that heat was able to escape because there was not as much gas repelling
