Upon getting information about an upcoming school science fair and the need to consider a topic of interest, many students will typically have no idea where to get started. While the science fair is typically a common occurrence in any school at any grade level, there are different types of topics that should be taken a look at depending on the age of the student. After first taking a look at the many different categories of science projects, you will be able to locate a suitable choice of topic to take to the next level.There is a wide variety of categories that fall under the types of science projects that can be chosen for a school science fair. These include biology, chemistry, physics, microbiology, biochemistry, medicine, environmental, mathematics, engineering, and earth science. While you may not have yet learned very much in any of these categories, don’t be afraid to see what each one entails. Taking a good look at your interests will allow you to focus on the right direction to take.Many resources are also available for those who are unsure as to the topic they are wanting to use to create their science projects. If you take a look at the topics that fall under the biology category, you will likely notice that there are topics that deal with plants, animals, and humans. For those who are in 2nd grade or 3rd grade, an interesting topic may be to determine if ants are picky over what type of food they eat. While this topic might not be of interest to an 8th grader, it is certainly something in the biology category that an elementary school student would enjoy.Along with the biology category, a high school student may want to take a look at diffusion and osmosis in animal cells as this would be a more appropriate topic for the grade level. A student in 6th grade would be more advanced than an elementary school student, but not as advanced as a high school student. At this middle school grade level, a topic of how pH levels effect the lifespan of a tadpole may be of interest.Whichever resource is used to locate a topic for science projects, it is always a good idea to consider the grade level of the student prior to making a selection. It is always assumed to be best to have a project at an appropriate level in order to keep the attention of the student and provide a fun and enjoyable learning experience.

Truth Issues – Manipulating Digital Data
What are some ways digitized output can be manipulated to fool people?The enormous capacities of today’s storage devices have given photographers, graphics professionals, and others a new tool the ability to manipulate images at the pixel level, For example, photographers can easily do morphing to transform one image into another, using image-altering software such as Adobe Photoshop. In morphing, a film or video image is displayed on a computer screen and altered pixel by pixel, or dot by dot. As a result, the image metamorphoses into something else a pair of lips morphs into the front of a Toyota, for example, or an owl into a baby. The ability to manipulate digitized output images and sounds has brought a wonderful new tool to art. However, it has created some big new problems in the area of credibility, especially for journalism. How can we know that what we’re seeing or hearing is the truth? Consider the following.Manipulation of Sound Could I tell whether or not sound has been manipulated?In 2004, country music artist Anita Cochran released some new vocals, including a duet, “(I Wanna Hear) & Cheating’ Song,” with Conway Twitty who had died a decade before the song was written. The producers pulled snippets of Twitty’s voice from his recording sessions, put them on a computer hard drive in digital form, and used software known as Pro Tools to patch the pieces together. Ten years earlier Frank Sinatra’s 1994 album Duets paired him through technological tricks with singers like Barbra Streisand, Liza Minnclli, and Bono of U2. Sinatra recorded solos live in a recording studio. His singing partners, while listening to his taped performance on earphones, dubbed in their own voices. These second voices were recorded not only at different times but often, through distortion-free phone lines, from different places. The illusion in the final, recording is that the two singers are standing shoulder to shoulder.Newspaper columnist William Safire called Duets “a series of artistic frauds.” Said Safire, “The question raised is this: When a performer’s voice and image can not only be edited, echoed, refined, spliced, corrected, and enhanced, but can be transported and combined with others not physically present, what is performance?,.. Enough of additives, plasticity, virtual venality, give me organic entertainment.” Some listeners feel that the technology changes the character of a performance for the better. Others, how-ever, think the practice of assembling bits and pieces in a studio drains the music of its essential flow and unity.Whatever the problems of misrepresentation in art, however, they pale beside those in journalism. What if, for example, a radio station were to edit a stream of digitized sound so as to misrepresent what actually happened?
Search Marketing Must Look To Training To Help Develop New Talent And Fill Skills Gap
At present there’s a real preference within the search engine marketing (SEM) industry to recruit team members with at least 2 years experience. However, this is proving difficult as the growth in search marketing activity is overtaking the growth of professional search marketers. So what can be done about the skills shortage?Companies have two possible options. 1) employ the services of a specialist search engine marketing agency to develop and implement their search strategy, or 2) recruit talent with potential and train them up in the different disciplines of search marketing.Search is in demand!With more and more businesses placing search high up on their marketing agendas it would make sense for them to do both. Companies will always benefit from having the strategic support of specialist agency to help them get to grips with the latest developments in search and to help them integrate search into their marketing mix. However, many of the day to day tasks associated with both pay per click (PPC) and search engine optimisation (SEO) can be effectively managed internally, providing that person has the right levels of knowledge to do so.In the current climate most organisations would probably be better off sticking with their agency but at the same time they should be thinking of developing a long-term training strategy to build up internal search marketing knowledge and skills.Building internal knowledge takes timeBuilding a team with solid SEO and PPC skills isn’t going to happen overnight and it does come with its risks. In a market that is short on supply of individuals with proven SEM skill sets, companies also face the prospect of a ‘brain drain’. There is the possible risk of recruits that have been trained up with these skills are then lured away by bigger players who are able to pay higher salaries.However, what is inevitable is that if the current trend continues and search marketers become few and far between then there will be a greater demand for agency support, and with demand outstripping supply, we could see companies paying a premium for search marketing agency services.Investing in search engine marketing training must not be viewed as a costly outlay but rather an investment. Companies that seize the opportunity to develop internal knowledge now, could benefit in the medium to long term by gaining a competitive advantage that is hard to replicate in the short-term.
