Do Certain Vitamin Supplements Help Vision Science Fair Project

When developing a science fair project it can be helpful to simply test common assumptions or claims about the cause and effect relationships between common products and our health. For example, do vitamin supplements help you to lose weight, grow longer hair or can they help your vision? Each of these questions and claims can be used for a separate science fair project. This sample science fair project is going to examine the effect that certain vitamin supplements have on your vision.

Hypothesis

The hypothesis for this science fair project is that vitamin supplements do not improve your vision. This hypothesis requires a little clarification. For the purposes of this project an improvement in vision will be defined as an increase is visual acuity as measured by a standard chart vision test. The dependent variable for this hypothesis is the visual acuity of the person and the independent variable is the type of vitamin supplement used by the test subject.

Supplies

To complete this science fair project students will need an eye exam chart, a tape measure, Vitamin C supplements, Vitamin E supplements, Vitamin A supplements and a placebo (sugar pill). The students will also need two to four test subjects for each of four test groups.

The Experiment

The control experiment group for this science fair project will be given a placebo. However, they will first be given a basic eye exam using an eye exam chart that is place ten to fifteen feet away from the test subject. The eye exam will be given for both eyes at the same time. After the eye exam is given the test subjects will be given a placebo supplement that they will take once a day for a month. At the end of the experiment another eye exam will be give.

There will be three test experiment groups. Group A will be given Vitamin A supplements, Group B will be given Vitamin C supplements and Group C will be given Vitamin E supplements. Again each test group will be given an initial eye exam. They will then take their supplements for a month. At the end of the experiment they will each receive another eye exam.

Data Collection and Analysis

The data that will be collected will be the eye exam results. These results will be measured in visual acuity ratios such as 20/15, 20/20 and 20/25. The analysis of the data will involve a simple comparison of the initial and post experiment eye exam results. If an improvement in vision is observed then the test subject will be given a score of 1, if they do not show an improvement then they will be given a score of 0. Each test group will have their scores averaged. The average scores will then be compared to the placebo group to see if the vitamins are helping and to determine which vitamin is helping the most.

Music Science Fair Projects

Music Science Fair Projects

Students and adults alike might be surprised that an interest in music and participation in a science fair can be combined. Music science fair projects are some of the most interesting demonstrations at the school event. Most people enjoy some style of music in their car, at home, with a personal music player, in a band, or at concert. Many people enjoy singing in a choir. What all these venues have in common is obviously music. What most participants do not realize is that there is science at work in every note they play, sing or hear! Music science fair projects offer the students and the visitors to the event to learn completely new concepts of science as they relate to music. Many of these people will leave the event with a deeper level of understanding of and appreciation for the magical science that is music!

Music science fair projects are chosen by students who have a love of the universal language that we all call music. The most creative students will choose music science fair projects to investigate the various topics surrounding the production and enjoyment of music. The first category of music science fair projects will focus on different ways to produce the tones that human being consider musical. This may include an investigation of the sounds of music from different cultures. Included in this are the unique instruments found around the world. Additionally, this may investigate the rhythms that different cultures gravitate toward. These types of music science fair projects will also demonstrate the creativity of students as they develop their own mechanisms for making musical tones. The most popular of these are crystal containers filled with various depths of water.

The other group of students presenting music science fair projects may focus on the effects that music has on people. Instead of examining the instruments, these students will explore the old adage that music hath charms to sooth the savage breast. There are still research studies being conducted on the soothing effects of music on various demographics of people as well as different animal and plant life. These students who present demonstrations and research findings on this data also increase everyones understanding and appreciation for the universal language of music.

Glass Fiber Plays An Essential Role In Science And Industry.

Glass Fiber Optics

A glass is an non-crystalline solid material. Glass plays an essential role in science and industry. The optical and physical properties of glass make it suitable for applications such as flat glass, container glass, optics and optoelectronics material, laboratory equipment, thermal insulator (glass wool), reinforcement fiber (glass-reinforced plastic, glass fiber reinforced concrete), and art. Glasses are typically brittle, and often optically transparent. Glass is commonly used for windows, bottles, or eyewear and examples of glassy materials include soda-lime glass, borosilicate glass, acrylic glass, sugar glass, Muscovy-glass, or aluminium oxynitride.

Strictly speaking, a glass is defined as an inorganic product of fusion which has been cooled through its glass transition to the solid state without crystallizing. Many glasses contain silica as their main component and glass former. Commonly, glass science and physics deal only with inorganic amorphous solids, while plastics and similar organics are covered by polymer science, biology and further scientific disciplines.

Glass fibre : glass fibres thread made from glass. It is made by forcing molten glass through a kind of sieve, thereby spinning it into threads. Glass fibres is strong, durable, and impervious to many caustics and to extreme temperatures. For those qualities, fabrics woven from the glass threads are widely used for industrial purposes. Glass fibres fabrics can also be made to resemble silks and cotton and are used for curtains and drapery. A wide variety of materials are made by combining glass fibres with plastic.

Glass ingredients

Pure silica (SiO2) has a “glass melting point” at a viscosity of 10 Pascal Second (100 P) of over 2300 C(4200 F). While pure silica can be made into glass for special applications (see fused quartz), other substances are added to common glass to simplify processing. One is sodium carbonate (Na2CO3), which lowers the melting point to about 1500 C (2700 F) in soda-lime glass; “soda” refers to the original source of sodium carbonate in the soda ash obtained from certain plants. However, the soda makes the glass water soluble, which is usually undesirable, so lime (calcium oxide (CaO), generally obtained from limestone), some magnesium oxide (MgO) and aluminium oxide (Al2O3) are added to provide for a better chemical durability. The resulting glass contains about 70 to 74% silica by weight and is called a soda-lime glass. Soda-lime glasses account for about 90% of manufactured glass.

Two other common glass ingredients are calumite (an iron industry by-product) and “cullet” (recycled glass). The recycled glass saves on raw materials and energy. However, impurities in the cullet can lead to product and equipment failure.

Glassmaking in the laboratory

New chemical glass compositions or new treatment techniques can be initially investigated in small-scale laboratory experiments. The raw materials for laboratory-scale glass melts are often different from those used in mass production because the cost factor has a low priority. In the laboratory mostly pure chemicals are used. Care must be taken that the raw materials have not reacted with moisture or other chemicals in the environment.
