How To Build A Greenhouse Grade 7 Science Fair Projects

A greenhouse is basically a structure that has been designed to capture and retain the heat from the sun. It is used to grow plants when the climate does not want to cooperate. Greenhouses can be used in a number of science fair projects and can be used to test concepts from a variety of fields of sciences including engineering, physics, botany and biology.

Project #1 Capturing Heat Energy

In this project the students will be designing a greenhouse that captures heat energy from multiple sources. They will be capturing heat energy from the sun and geothermal heat energy from the ground. This project will require the student to learn about heat extraction techniques related to solar energy and geothermal energy.

Sample hypotheses that can be tested with this project include:
(1) The thickness of the plastic used for enclosing the greenhouse impacts the amount of heat conservation in the greenhouse;
(2) The opaqueness of the material used for enclosing the greenhouse impacts the amount of heat conservation in the greenhouse;
(3) The depth of the insulation on the floor of the greenhouse impacts the amount of geothermal heat conservation in the greenhouse.

Project #2 Growing Radishes

In this project the student will build a greenhouse so that they can grow radishes and conduct experiments on the radish plants during times of the year that are not normally conducive to gardening. Radish projects can look at a number of things. For example, students can try to cross pollinate radishes with another root vegetable like carrots, they can attempt to grow radishes in sand or they can try to manipulate the size of the radish by exposing the plant to 20 hours of light per day.

Project #3 Engineering Greenhouses

For students that are interested in engineering, greenhouse science fair projects can be developed with an engineering focus. For example, students can try to develop a greenhouse using nothing but materials that are normally thrown out or recycled, such as cans, bottles and plastic containers. Students will not only need to design and build their greenhouse, but they will also need to test the effectiveness their greenhouse has in regards to collecting and conserving heat energy.

Project #4 Studying Solar Energy Applications

The final project option will be an application project. Students will be learning about solar energy and how to use this knowledge to harness the suns energy to heat a greenhouse. For this project students will design and build a greenhouse that maximizes the energy delivered by the sun. A good approach for this project is to see if their design can magnify solar energy within the greenhouse to make it effective in cold weather.


Atx Technologies Car Tracking Device And Its Unrivaled Features

The concept of a car tracking device has been known as a different or independent gadget. However, even phones can still have this feature with help of your mobile phone. An example of these devices is ATX Technologies car tracking device which is installed on your mobile phone. The benefit of this device is that there’s no need for you to have two devices on hand. This is a small gadget was manufactured in 1997 and has been reduced to its size for mobile phones. This employs the services provided by AT&T, a known network provider, so it can give a wider network in terms of tracking vehicles. BY utilizing AT&T services, the price of using this gadget on a monthly basis as been reduced since it will not charge any mobile phone fee. This is good for consumers who don’t like to carry two gadgets while on road.

In a sense, ATX Technologies car tracking device is a project brought about by ATX Technologies in partnership with Standard Communications. The latter produces wireless communication solutions and is situated in San Jose. They will embed the miniature device on mobile phones. With the help of AT&T in providing he wireless services, consumers will get remarkable affordable prices than the usual rates offered by other tracking device manufacturers. What’s great about this device is it can help in locating cars in any case of theft or loss at a flat rate offered by AT&T.

In using this tracking device, the car owner just need to call the OnGuard Response Center. The LS unit will then be activated. The police will be notified after the response center is able to track down the vehicle. After processing the necessary procedures within the police department like obtaining an authorization, the OnGuard Response Center will deactivate the car’s ignition using a remote control. Hence, the vehicle will be stationary and wait for the police to locate it. This is perhaps the most popular and unrivaled feature of the ATX Technologies car tracking device. Without a doubt, this gadget will be helpful for car owners to be confident about their car’s safety.


Forensics vs Forensic Science

If you bring up forensics in a conversation, those involved will often start thinking of scenes from the television show CSI (Crime Scene Investigation). It’s synonymous with scouring crime scenes for minute clues to help criminal investigators create leads in various cases.

Because of the misunderstanding that’s developed about criminal investigations and forensics, many don’t realize that there is an acute difference between forensics and forensic science.

Currently, forensic science gets shortened in most discussions to “forensics.” The word “forensic” actually relates to debates, and comes from the Latin word “forensis” or “of or before the forum.” This concept became most prominent in ancient Rome where both the accused and the accuser involved in a judicial case had to advance their arguments in front of a public forum. This led to the usage of the term “forensics” for both public debate and the presentation of legal evidence.

This concept of “evidence” is what has caused it to run parallel and merge with forensic science. As the judicial system evolved, so, too, did the evidence that was required in cases. No longer was it a matter of verbal debate; instead other forms of evidence were necessary. The concept, that being “forensic” or “before the forum” still holds true. The only thing that has changed is the type of evidence that’s being presented.

While some modern dictionaries will actually merge the two and provide similar or identical definitions, they are quite separate by origin and practical application.

The term forensics refers to public debate which includes the presentation of evidence and rhetoric. Forensic Science is something different. It deals specifically with the gathering, identification, research, and scientific interpretation of evidence to determine such things as who was involved in a crime.

In addition to confusing the terms forensics and forensic science, people often mistake forensic science for criminalistics. However, it’s important to keep these terms in context too. Forensic science involves any discipline that can be applied to evidence. Criminalistics is just one of the subdivisions of forensic science.

Some of the disciplines that fall under the umbrella of “forensic science” are:

-Computer Forensics -Forensic Accounting -Forensic Audio Engineering -Forensic Linguistics -Forensic Pathology -Forensic Psychology -Forensic Engineering -Criminalistics

Criminalistics itself is the scientific discipline which brings together various natural sciences such as biology and chemistry to the examination, identification, and comparison of certain types of evidence. Criminalists deal with biological evidence including DNA and bodily fluids, trace evidence such as fibers, hair, and soil, and impression evidence such as fingerprints and tire tracks. They also are involved with ballistics, drug analysis, crime scene photography and reconstruction.

As you can see, the forensic sciences deal specifically with the research and examination of evidence so that such evidence can be admitted to and used within the legal system. Forensics on the other hand should be viewed not as the science behind the evidence, but as the presentation and use of the research once it’s completed.


Affordable Website Development Different Technologies can Develop Best Website

Web developers use many several types of technologies and skills for the website development. They update their information and gain knowledge of new technologies. For develop site for a business creators follow some frameworks, tools, coding languages, and various methodologies. There are various technologies are use by them like HTML, Cake PHP, MySQL & Apache, Kohana, Open Source, Symphony, Web Engineering Technologies, CSS and Java Scripts, web content development, client and server side scripting, e-commerce development, network security configuration. There are various tools are also use by them like Adobe PhotoShop for graphic designing, Macromedia Dreamweaver and much more. Website Development is generally known as non-designing part like writing coding and markup but it may include designing part. Design an affordable website is also play an important role in web development.

Choose a website creating company that offers an affordable website development and ensure you for reliability and presentation standard. Portal development is complex and companies face several types of challenges at the time of website making. The main focus of company should be to create all types of business and web communities. Web Portal can also define as a website with lots of pages and some features like videos, image gallery, and blog community, real time chat, voting poll and etc. so user can simply discover all related information at one place. Maker of portal are also write business specific content for site for user easiness. For creating web portal, a company has the team of developers which consist of hundreds of people.

The process of develop an affordable website is like a software development and it follows special and numerous steps. Maker of a site follows some process for an affordable website development. First of all they do the plan and analysis the requirements and after that they make information design then they also see the design and construction of a site because it is also important for the marketing point of view. These processes will help to make an effective and quality and excellence site. Different clients have different needs, goals for a project so at the time of making a site they consider about these requirements. Testing is also an important part of a portal development. After the completing a website it will go for a review and testing and if client wants any changes in that he will inform the maker and they will make changes and give the client 100% satisfaction.


Pharmaceutical Sales A Great Career For Science Degree Graduates

So you graduated with a bachelor of science degree and you dont want to become a doctor, dentist or work in a lab. You also dont intend to pursue a graduate degree in science either as scientific research is not really your calling. So you might be thinking about what type of careers and jobs are open for university or college graduates with science degrees.

I was in that same situation many years ago as I felt that I would prefer wearing a business suit rather than a lab coat for my working career. I wasnt interested in Petri dishes, Bunsen burners, flasks or dissection tools anymore. I wanted to carry a snazzy briefcase and have business luncheons instead.
So I was fortunate enough to stumble into a career field that I would stay in for fourteen very lucrative and rewarding years. This career was in pharmaceutical sales which turned out to be a perfect match of science and business.

There are many perks and benefits when working as a drug rep in the pharmaceutical industry. Salaries and bonuses could amount to six figures for high achievers and there is the use of a company car. Corporate expense accounts are also available for business entertaining. There are also the travel opportunities that are paid for by the company as many sales meetings as well as medical conventions are often located at nice places.
Being a pharmaceutical sales representative also means that there is a lot of freedom and independence with the job as fixed working shifts are no longer the way for a drug rep. Even better is that for 95% of the time, there is no boss to look over your shoulder while on the job.

Being a drug rep also has some intangible rewards I didnt expect when I first started. The field involves working with medical professionals to bring them useful products that will greatly benefit their patients. Drug reps with pharmaceutical sales forces can be considered as part of the overall health care team since they are playing an important role in helping patients.

So if you are a science graduate and want to do something in business rather than in a purely scientific field, consider pharmaceutical sales as a viable career option.


The Two Parallel Entities Of Human Life Science And Religion

The two important things in human life are science and religion. Religion requires us to believe in a certain event without discussing too, in science the other hand requires to believe, but after a string of research in the field. No doubt several times science is parallel to our religious beliefs, as we believe that there are other creatures in the universe as we do, and scientists are also investigating the extraterrestrial presence in the world and the universe.

Contrary to this, science does not believe in controlling power, like God, who created the world in just seven days. According to the theory of big bang the whole universe is the result of a powerful explosion.

Scientist believes this theory, the most accurate and appropriate to describe the beginning of the galaxies and solar systems like ours. Undoubtedly, the scientific issues are unquestionable, but there is still no power to control.

Similarly, Christians, Jews and Muslims believe that the creation of a human baby in its mothers ovary is the most vibrant in the presence of God that is able to provide sufficient air for food, shelter and fresh unborn baby. But science is ultimately supporting this idea. And all this creation is called the natural process of bearing babies.

Spirituality and Science

No matter what happens, its proven that after a few years or decades, the scientific ideas of all events related to religion. Like the famous theory of the world of 2012 is based on the Mayan calendar, which was also represented by the ancient religious. Moreover, the concept of Judgment Day can be seen in the sacred books of the Muslims and Christians.

Undoubtedly, scientific research has proven many things that were once based on myths, as the 17th century Galileo was convicted under the orders of the Christian Church, and challenged the theory that the sun revolves around the earth, and said that the Earth revolves around the Sun Hence its now demonstrated that he was right which means that science is also helping us in evaluating our bad decisions.

As this is some tough questions that science cannot answer on purpose. How to cure deaths, without consulting a doctor or medication. There are saints, and gurus Sufis are powerful enough to show some amazing things. Thus, scientists and researchers representing powerful entity such as supernatural. Another thing that have nothing to say, as scientific ideas are quite different in some cases. This is the complete information framed in short about science and religion and its importance in human life.

Why Are Teens So Stressed Science Fair Projects

The topic of your science fair project is critical to its success. If you select a topic that you are not interested in you will find the process of completing a science fair project boring and tedious. However, you can overcome this problem by focusing on something that either interests you or that impacts your life directly. Here is a topic for this year’s science fair project “why are teens so stressed?”

Background Research

“Why are teens so stress?” This is the topic for your science fair project this year. So now that you have a topic your next step is to conduct research on this subject. This research will need to begin with a general search of teen stress. The results from this search will provide you with leads on what is stressing out teens and what research has already been done.

Develop a Hypothesis

Now that you know a little bit about your topic your next step is to develop a hypothesis. Your hypothesis will predict what is stressing out teens. For example, your hypothesis may be that teen stress rates are impacted directly by the stricter entrance requirements for college.

Develop an Experiment

After you have a hypothesis you will need to find a way to test that hypothesis. If your hypothesis is that teens are stressed by the increase in acceptance standards of colleges then you will need to design an experiment that tests how these higher standards are impacting student stress levels. You can do this by collecting data on college entrance requirements from the 70s and comparing them to those of today, and you can also conduct interviews with teens to figure out how stricter college entrance requirements are impacting their stress levels.

Collect Data

Data collection for this type of science fair project will involve collecting data and information from government and nonprofit sources, as well as collecting data directly from your own test subjects. When you are collecting data from your test subjects make sure your test conditions remain constant for each experiment. This will help to ensure your data is reliable and valid.


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 is 3D printing technology used in Architecture and Medicine

D printing technology is used to manufacture prototypes, tools, and end-user parts directly from a CAD design. This printing technology offers unprecedented flexibility as it can create a part of any dimension out of any material. Some of the 3d printing materials used include metals, polymers, ceramics, composites, and many more. The 3D printing technology has complete control over material composition, surface texture, and micro-structure of the prototype. 3D printing technology also allows the user to construct prototypes using two different materials. >

Lets take a look at this amazing technology and how it has affected the field of architecture and medicine:

3D printing for Architecture

Architects know that there is nothing like a physical model of a building when it comes to displaying their work or design concept. Physical models also play an important role when it comes to explaining and convincing the customer while selling a project.

3D printers are affordable and high quality solutions for architects. Building a physical model requires great deal of expertise, precision, and time. 3D printing machines help designers focus on their building design, while the devices make 3D models of the project.

Many architects are not tech-savvy and are not used to operating complex devices. 3D printers do not require human intervention at any stage of the printing process. Architects just need to need to draw a CAD diagram of the project and instruct the 3D printer to build a 3D model. The 3D printer can print the model within a few hours, which can then be presented to the client.

3D printers are capable of producing of 3D models with accuracy and speed without compromising on the finer details of the architectural project. The price of desktop 3D printing machines is not that high and independent architects can also afford them.

3D printing for Medicine

The application of 3D printing technology can also be found in the production of medical devices. There are different 3D printing materials available that can be used to build real parts. For example, manufacturing hearing aids is a complex process because they are custom-fit devices and cannot be mass produced. 3D printing greatly helps in such matters where medical devices need to custom-fit a patient.

The future of the 3D printing technology is very bright. Market experts state that 3D printing technology will be affordable to the masses by the next decade. The prices of 3D printing devices are falling rapidly, and it is believed that the prices of 3D printers will drop by as much as 80% in the next 5-10 years. It will not be a surprise to see 3D printing devices in each household just like refrigerators, washing machines, and televisions.
