Do Different Liquids Produce Different Levels Of Urine Science Fair Projects

Students have many options when it comes to the development of their science fair projects. If students are interested in medicine or biology then this project is a great option. It will examine how different types of liquids are processed by the body.

Hypothesis

The hypothesis for this science fair project is that sugary liquids produce less urine then salty liquids do. The dependent variable in this hypothesis is the amount of urine produced and the independent variable in this hypothesis is the type of liquid that is drunk.

Supplies Needed

This science fair project will need several key pieces of equipment. First of all the student will need at least six to twelve test subjects that are generally healthy. The student will then need a urine collection and measuring device for each of their test subjects. These can be picked up at a medical supply company. The students will also need collection sheets which will be handed out to each test subject. Latex gloves can also be used when collecting urine volume samples.

The Experiment

To start with the student will need to conduct a control experiment. This will create a baseline of data to compare test results to. The control experiment will basically see how much urine is normally produced by each test subject on a daily basis. To collect this data each test subject will be given a urine volume collection container that fits into their toilet. They will then write down the volume of urine that they eliminate from their bodies on a daily basis over a week.

The test experiment will begin by dividing test subjects into two groups. Group A will be given sugary drinks and Group B will be given salty drinks. Each group will be assigned the same volume of liquid. The test subjects will be instructed not to drink anything other than their experiment liquids during the day. They will then monitor their urine output during test day 1, 2 and 3. The groups will then be given the other liquid type and the will be tested for another three days.

Data Analysis

The analysis of the data will involve several steps. First of all the students will need to organize the data by finding the average urine output for each test subject in the control experiment. This will create the baseline data. Next the average urine volume output for each test subject will be calculated for the sugary drink test. Finally the average urine volume output for each test subject will be calculated for the salty drink test. The results will be compared. Students will need to look for trends that indicate that the sugary drinks lead to a higher urine output change compared to the control than the salty drinks did to prove the hypothesis could be true. Otherwise the hypothesis is false.

Environmental advantages of Suspended Particle Device Glass Technology

The idea of the “home of the future” usually contrasts with the idea of environmental responsibility. The perception of technology being detrimental to ecologicial stability is slowly being replaced with the advent of smart technologies such as Suspended Particle Device or SPD glass.

What is SPD Glass?

In the area of light control, there are three main technologies: polymer liquid crystal devices (PDLC), suspended particle devices (SPD) and Electro chromic devices (EC). All three may be used to produce smart glass, which is described as a glass that can change its light transmission when a voltage is applied. In a nutshell these technologies control the opacity of glass via a control method (sensors, remotes, wall switches etc) to regulate the amount of light allowed to pass through it. SPD is generally the technology of choice for use in external or solar control windows because of its reliability, price, performance, and manufacturing advantages and aesthetics.

Energy and Lighting Costs

In terms of home and office environment SPD glass facades, windows and skylights can be used to more efficiently reduce the need for air conditioning during the summer months and heating during winter.

The ability to instantly switch the glass to maximize daylight when it’s really needed and to provide controllable solar shading during peak light conditions is valuable and unique. SPD Glass has even advanced to the stage where light sensors can automatically adjust the opacity of the glass according to programmed settings. This low energy electric current saves overall temperature control and lighting costs and also reduced carbon emissions related to building maintenance.

Hygiene and Health

These SPD glass panels provide a hygienic alternative to curtains and blinds as they do not trap bacteria, grime and dust. Easily cleaned surfaces mean both a savings on cleaning agents and a cleaner environment for homeowners and building owners. Taking advantage of healthy natural lighting without the glare is the smart way to reduce eye strain and protect the skin from UV damage.

Maintenance savings

Professionally manufactures Suspended Particle Device technologies such as SPD glass utilise a highly durable, solid-state technology with no moving parts to wear out or break. Sun damage such a fading carpets, artwork and furniture is also greatly reduced making your interiors last longer. If you combine this interior longevity with the longevity of the physical glass itself you have a winning combination for your pocket and for the environment.

How To Design A Triboard For A Science Experiment

One of the last things that a student does when working on a science fair entry is to create their display board. While many students rely on a simple 2 dimensional piece of poster board for their display board, others go the extra mile by using a triboard for their display piece. A triboard is a great option as it is designed to stand up on its own and it offers three large panels that students can use to display information about their science experiment.

What Is a Triboard?

A triboard is basically a foam board that has been precut and reinforced so that it has two joints. The two joints segment the board into three panels. The two outer panels can be positioned so that the entire triboard stands up on a table or desk without external support. Triboards are sold in art supply, craft and office supply stores. They generally come in white and black, and occasionally they can be found in designer colors like blue or neon colors.

Panel #1 The Introduction to Your Project

The first panel of your triboard needs to be dedicated to introducing your science experiment. It will identify the hypothesis that you selected, the reason why this topic is important and it will explain how your experiment was set up. The graphic elements that this panel will contain will focus on the materials used in your experiment and the experiment set-up.

Panel #2 The Experiment

The second panel will focus on the experiment and the collection of data. This panel will have the most graphic elements. The graphics that it will need include charts, graphs and photographs. Each graphic element will need to be labeled. In addition to the graphic elements, text elements will also need to be posted on the middle panel. First of al the title of the experiment will be found on the second panel. You will also want to add text panels that describe the data that was collected.

Panel #3 Conclusions

The final panel will summarize your findings and talk about the conclusions that you have drawn. This panel will have the least amount of graphics. It will instead have bullet points that explain your results and that also explain how the data either supports or negates your hypothesis. The final panel can also include a list of questions that still need to be answered or research you think still needs to be done on your topic.

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.
