When it is summertime and I go on a run, my parents say, “Make sure you wear a light shirt!” Once, I asked why, and they said it was because the light colors don’t absorb as much heat, so I wouldn’t be as hot. The opposite was for cold weather. When I had to go outside for a while in the cold, I made sure to wear a black or dark top, because then it would absorb more heat and keep me warmer. I have always been curious about how this works, and if it works, for that matter (Parents can be wrong, you know). Also, the concept of energy simply intrigues me. This is why I decided to find out more about how colors on a shirt, or anywhere else, can affect temperature. When I started my research, the literature (or scientists) explained that a color will, in fact, affect the temperature of that object. This temperature is measured by using an infrared thermometer and a couple of large math equations. With this information, one can then calculate the rate of energy absorption of each color.
For this discussion, I am referring to thermal energy, also referred to as heat. Heat is actually light, but it is a light that is invisible to us, or not in the visible portion of the Electromagnetic Spectrum. Infrared light is the heat that we refer to normally and is located just below the color red in the Electromagnetic Spectrum. Its name is literally its definition. “Infra,” which means “below,” then “red.” So, infrared, or “below red,” is below red on the Electromagnetic Spectrum. We can see things that do not give off their own light because of reflection. When a color reflects light, the light reaches our eyes and allows us to see the color. This means that if we turn the light off in the room, we cannot see the colors because they do not give...

## Different Theories Of How Students Absorb, Process, And Retain Information

- In this course I examined past and present theories of how students absorb, process, and retain information, while also being introduced to a variety of instructional strategies. These strategies include incorporating research based Kagan strategies, multiple intelligences, and differentiated instruction into the lesson planning. One of the first things I did at the beginning of the year was to introduce what the multiple intelligences are. Students filled out a getting to know you survey, which asked them to rate each statement according to how well the description fit them....   [tags: Intelligence, Learning, Education, Skill]

## Light as a Raw Material of Photosynthesis Essay

- Photosynthesis is the process of making glucose using the raw materials water, carbon dioxide and radiant energy. Which is trapped by the chlorophyll molecules and then oxygen is given off as a bi-product if the process. It is the conversion of radiant energy into chemical potential energy. The occurrence of photosynthesis is very important to us as humans, because it provides us with the oxygen we need to breathe and plants are at the bottom of every food-chain and so without them, I would collapse....   [tags: radiant energy, chlorophyll, glucose]

## Carbon Dioxide Can Absorb Energy From Infrared Radiation Essay

- Carbon dioxide can absorb energy from infrared radiation due to its structural qualities. Carbon dioxide absorbs incoming infrared photons, wherein the energy from the photons causes the carbon dioxide molecule to vibrate. This allows the carbon dioxide mole to give up this extra energy by emitting another infrared photon and once the extra energy has been removed by the emitted photon then the carbon dioxide molecule stops vibrating. Therefore, carbon dioxide molecules have the capacity to absorb and re-emit infrared energy, which is what allows it to be an effective greenhouse gas....   [tags: Carbon dioxide, Oxygen, Climate change, Infrared]

## Adapting to Different Environments: Examples of Some Novels with that Theme

- Those who adapt to their surroundings have a sense of self acceptance of where they’re from and where they are now. However, this is not always the case for the individuals we read about in the four autobiographies. As the different individuals reminisced about their past, we were able to identify key elements in the story that showed us how these different individuals were able to adapt to survive in their environments. In these autobiographies, we were able to get a glimpse of the different childhood lives these authors experienced....   [tags: Growing up, Cultures, Different]

## Light, The Primary Source of Energy in Photosynthesis Essay

- Light has a wave nature and particle nature. The smallest parts or units of light are called photons and the amount of photons absorbed per unit time determines the brightness of light. Wavelengths are a certain amount of energy each photon possesses as they vibrate. Chlorophyll reflects the wavelengths green part of the light spectrum because it is green and the plants that contain chlorophyll are green as well. This article may not be reliable because there was no date or author noted. This article clearly examines in what form light is absorbed and the process thereof....   [tags: carbon dioxide, wavelength, absorb]

## The Importance of Light During the Photosynthesis Process Essay

- Photosynthesis is a chemical process by which green plants use the radiant energy to synthesize certain nutrients using water and carbon dioxide. This process to happen efficiently it requires the presence of light, water carbon dioxide, chlorophyll and enzymes. During the process of photosynthesis, carbon dioxide plus water in the presence of sunlight, enzymes and chlorophyll produce glucose and oxygen as waste product. The radiant energy is broken down the water into hydrogen atom and oxygen atoms, these atoms combine with carbon dioxide to make glucose and oxygen....   [tags: green plants, chlorophyll, radiant energy]

## Essay on Investigate how PH Affects the Ability of Raw Meat to Absorb Water

- Investigate how PH Affects the Ability of Raw Meat to Absorb Water I am planning an experiment to investigate how PH affects the ability of raw meat to absorb water. · Independent Variable The independent variable for this experiment is the PH of the solution the steak is marinated in. I will achieve a range of different PH values by using buffers set at PH 1, 3, 5, 7, 9. I predict that there will be an optimum PH where the steak will absorb the most water. The amount of water absorbed by the raw meat will increase as you increase the PH up to the optimum and then decrease the PH as the PH increases past the optimum....   [tags: GCSE Biology A2 A-Level Coursework]
