Blue light

Transcript: By: Anna Cain Blue Light The light that comes from the sun appears white, but it is actually made of every color of the rainbow. As light passes through a prism, the light is separated into all of its colors. The prism is a specifically shaped crystal. Light energy travels in waves. Some light travels in short waves, and others in long waves. Blue light waves are shorter than red light waves. Sunlight reaches earth's atmosphere and is scattered in all directions by the particles and gasses in the air. The blue light is scattered more because it travels in shorter, smaller waves. This is the reason the sky is blue majority of the time. Why the Sky is Blue Why The Sky is Blue Blue light, or high energy visible (HEU) light, is a type of light with short wavelengths emitting a higher energy. It has one of the shortest, high energy wavelengths on the spectrum. In natural sunlight, blue light is always visible, but blue light is not only in sunlight. TV's, computers and phones use blue light for their screens. What is Blue Light? What is Blue light? Pros and Cons of Blue Light Pros: Blue light can help boost alertness Boost memory and cognitive function May even elevate your mood Cons: Can lead to eye strain Could lead to damage in retina cells (Cells found in the eye Potential molecular degeneration - Blurred or loss of vision Leads to sleeping issues, restlessness Blue light can disrupt your biological clock To an extent, blue light can lead to cancer Pros and Cons of Blue Light Blue light is both good and bad, and the difference is balance. If you only expose yourself to a limited amount of it, there will be positive effects, such as mood elevation. But, if you expose yourself to too much, all of the negative impacts will take effect on you, such as eye strain, molecular degeneration, and others. If you find the right balance, blue light will be safe to use. The Difference The Difference Protection Against Blue Light Protection Against Blue Light One technology used to prevent blue light reaching your eyes is a type of screen protector. This thin, clear screen protector has a blue light filter on it. Therefore, the blue light does not go through the screen and to your eyes. Another technology used today is blue light glasses. These glasses have a blue light filter in the lens. When you wear these blue light glasses, the negative effects and rays will not reach your eyes. Biological Clocks Biological Clocks Biological clocks and circadian rhythms are connected to blue light. Biological clocks and circadian rhythms is an internal mechanism that controls the psychological activities of yourself. It can change daily, weekly and yearly. They are connected to blue light because when you are exposed to blue light, it alters our biological clock, which is the reason that when you are exposed to it, you have troubles sleeping, and your internal schedule is altered. Sunlight contains both ultraviolet (UV) light and blue light. UV light is part of the non-visible light spectrum. Everyday, when we are out in the sun, we are exposed to UV light. It can cause damage to our eyes, specifically the lens and cornea. UV light can cause sunburn and destruction of vitamin A. It can lead to skin thickening, wrinkling and possible damage to DNA. Blue light, which is part of the visible light spectrum, goes deeper into the eye, and can cause permanent damage to the retina, which leads to problems such as molecular degeneration. In conclusion, UV light is more negatively damaging to the whole body, and blue light only takes effect on the eyes. Blue Light and UV Light Blue light and UV Light

The blue light filter that you can turn on isn't as bad for you eyes but it is no means good for your eyes. Phone Computers 2 For the computer there are a couple options. For one there is a custom screen that you can buy for your computer, but they are pretty expensive. They is also a blue light filter but it is pretty hard to find on your computer. Computers How are the concepts of biological clocks and circadian rhythms connected with blue light By Garrett Colten How are the concepts of biological clocks and circadian rhythms connected with blue light Blue light has a fliccering patterm that effects your circadian rhythm. Your circadian rhythm is your own biological clock which effects your daily, weekly, yearly cycle. 1 Your Circadian rhythm Biological clock- Your biological clock is a mechanism that controls your physiological activites on a daily basis. Circadian rhythm- Your circadian rhythm is your 24 hour clock inside your body which controls a physiological process of living beings.

Transcript: Grace Haupt What I like to do in the snow! I like to go snowboarding and sledding in the snow. Snowmen are fun to build because you can customize them in any way. Also,I like to build snow huts for the animals and just for fun! Snowflakes are made by cold water droplets falling down when there is pollen and dust in the air. The pollen and dust make the frozen water droplet have 6 spokes. How snowflakes are made. Snowflakes Snowflakes are made with extremely cold water droplets,pollen and dust. The ingredients in snowflakes.

Snowflake Presentation

Transcript: Snowflakes By:Emma-B. Faul Period D Chemistry Honors A snowflake occurs naturally when a droplet of water freezes onto a dust particle floating in the sky. Why they occur? Why they occur? Diagram What Happens? All snowflakes start off as water molecules up in the sky. 1 2 3 4 Water molecules move around bouncing off of each other until the ait pressure drops and they stick to each other. As these snowflakes grow they create a crystalitis and then creates their own unique shape. When these moelcules stick together they create a hexegon-six point symetry What exactly happens? Types of Snowflakes: Types of Snowflakes: There are 39 categories of snowflakes that can be further broken down into 121 subtypes. All of this can be grouped together into 8 general categories. Column Crystals Columns and Needles Columnar snow crystals appear when the temperature is around 21 F, and are quite common. They are small and easy to miss, however, they will look like small bits of white hair on your sleeve. Especially long, slender column crystals are often called needle crystals. Hollow columns have hollow areas in both ends. Capped Columns Capped Columns They are not very common, but they are actually pretty easy to find if you go looking for them. A basic capped column is shaped like two wheels on an axle, or an empty spool. Multiply capped columns have additional plates between the outer two. A capped column forms when it travels through different temperatures as it grows. First a column forms 21 F, and then plates grow on the ends of the columns 5 F. Stellar Dendrites Stellar Dendrites These are the most recognizable snow crystals. Their name comes from their star-shaped appearance, along with their branches and side branches. Dendrite means tree-like. Stellar dendrites are also quite large and common, so they are readily spotted. The best ones usually appear when the weather is quite cold +5 F. Fernlike Stellar Dendrites Fernlike Stellar Dendrites These crystals are like Stellar Dendrites, but larger and leafier, with many sidebranches that resemble the branches of a fern. If you look carefully, you will see that the sidebranches mostly run parallel to their neighboring branches. You will also see that these crystals are not perfectly symmetrical. These are also the largest snow crystals, and specimens up to 5mm in diameter can be found. Triangular Crystals Triangular Crystals It appears that aerodynamic effects helps to produce these unusual snow crystals. They are typically small, shaped like obtuse triangles. Sometimes branches sprout from the six corners, yielding an unusual symmetry. Diamond Dust Crytals Diamond Dust Crytals These tiny snow crystals look like sparking dust in the sunlight, which is where they get their name. They are the smallest snow crystals; many are no larger than the diameter of a human hair. The basic ice crystal shape is that of a hexagonal prism. Twelve-branched Snowflakes Twelve-branched Snowflakes If two small six-branched snow crystals collide in mid-air, they might stick together and grow into a twelve-branched snowflake. You might think such ideal collisions would be rare, but twelve-branchers are actually not that unusual to see. Rimed Snowflakes and Graupel Rimed Snowflakes and Graupel Snow crystals grow inside clouds made of water droplets. Often a snow crystal will collide with some water droplets, which freeze onto the ice. These droplets are called rime. To be considered a snow crystal it must only have a few droplets of rime. Blobs of rime are called graupel, or soft hail. Interesting Facts Interesting Facts Everyone has heard the saying "Each snowflake is unique just like each person is unqiue." There are endless options for what snowflakes can become and grow into. Identical Snowflakes?? Identical Snowflakes??
