Science Fair Project Topics For Winning Science Projects


There are countless science fair project topics. To figure out a topic, you must first decide on a category of interest; Astronomy, Biology, Zoology, Chemistry, Earth Science, Engineering, Environmental, Microbiology, Physical Science or Mathematics. Once you have found a category that you like, you can then decide on a topic. It may not be an easy task, since there are countless topics on each category, but it will not take you long before you choose something that really interests you. Just remember that any project has the potential to be a winning science project, and keep in mind that the judges are looking mainly at presentation and whether or not you learned something from the project.

You don't want to pick a topic that is too easy, nor do you want to choose one that is beyond your level. The judges want to see that you are knowledgeable about your project and that you have documented your findings. Obviously, the first thing they will notice is your presentation, so you want to make sure it's eye catching and well organized. If you use graphs in your project, make sure to double check your figures and ensure you understand the graphs you are presenting. If you can't explain your work, you are definitely going to lose points. Basically, if you chose a topic that interests you, is on your skill level, that you genuinely learn something from your project, are able to show and explain your work, and present the project in an organized and eye catching manner, you are likely to score great points with the judges.

Good Science Fair Projects - Plants Reaching For Light (Part Two)


In our previous science fair project we had a look at chlorophyll and how plants use this chlorophyll, sunlight, water and carbon dioxide to produce glucose (a form of sugar.) What else, that is very important, is produced through photosynthesis? (In the process carbon dioxide is taken from the air, what is released back into the air?) Now we are going to do a good science fair project to demonstrate how plants actually reach for sunlight. We know by now that they cannot survive without light, which we proved in our previous science fair project. Now we are going to do a really fun science fair project. If you want to do a really good science fair project, it might be a good idea to combine these two science fair projects as it gives you a very clear and visual picture of plants growing and needing sunlight.

Today's science fair project is a good science fair project for someone that is a little handy. We are going to make a maze in a shoe box to demonstrate how the plant searches and reaches for light.

What you will need for this science fair project:

* First you need a shoe box

* You will need a pair of scissors

* Stiff card

* Some sticky tape

* Black paint

* A paint brush

* A pair of gardening gloves to protect your hands

* A runner bean

* A plant pot

* Some good compost

* Water

Now for the fun part: making your maze in your shoe box!

1. To start cut a hole in the one end of the shoe box.

2. Making a maze in your shoe box is very easy, start by cutting eight flaps out of the stiff cards. The flaps must fit securely into your shoe box in the width.

3. Now paint your shoe box and the eight flaps all over with black paint. Do you know why we are doing that? Think about the light reflecting...yes, the black paint is to stop the light entering through the hole from reflecting inside the shoe box!

4. Now you can make a maze by sticking the eight flaps of card inside the shoe box with sticky tape. Cut slots into your flaps at a different place in each flap to form a maze (if you are not sure how to do this, ask for the help of an adult who knows what a maze looks like.)

5. Plant a runner bean in a small plant pot with compost.

6. Water the soil each day to keep it moist but, do not make it too wet. Keep it in a warm place until the bean has a shoot. Remember to keep the soil moist, depending on the temperature; it may not be necessary to water the bean everyday.

7. When your plant has a shoot place it at the bottom of your maze.

8. Close the lid and place the maze in a sunny spot.

9. Remove the lid once a day to see if your plant needs water.

10. Now you can observe what is happening.

11. If you did it right, the plant will grow and find its way through your maze to steadily move towards the light.

12. Eventually your plant will poke through the hole at the top of your shoe box.

13. For display purposes it is a good idea to take a photo of your plant growing zig-zag through your maze and out the hole at the top.

This is a good science fair project for someone interested in gardening. It is also a good science fair project for someone that loves crafts as this can double as a craft because of the maze you have to make. Good science fair projects can never be done too fast, so give yourself enough time.

Careers in Forensic Science


Forensic science is one of the most challenging and stimulating careers that someone can choose for a litany of reasons. This is because, unlike other science careers, forensic science deals with the law and most particularly criminal law. What a forensic scientist actually does, is to use science to come to conclusions and solve puzzles with regards to evidence that has been gathered at crime scenes.

Unlike other scientists however; the forensic scientist must be able to defend their conclusions in a court of law. So it is imperative that the conclusions that a forensic scientist arrives at be flawless, because if any of their science is less than credible in one case it can also mean that the conclusions in other previous cases may too be called into question.

Many people are drawn to a career in forensic science because it is a science career that allows them to help people who have been victimized find justice. Problem solving and real life puzzles are still more reasons why people are so drawn to forensic science as a career choice.

Forensic science is continually advancing and new methods of finding answers to the puzzles that are left at crime scenes are continually being developed and tested. This means that a career in forensic science can involve making new discoveries that can be used to solve crimes in the future.

Job security is still one more factor that can't be ignored and with so many peoples lives being disrupted by a job loss, forensic science is a career that you can count on to stay with you your entire life.

Forensic science is not only intellectually stimulating but it is also financially rewarding as well and with the need for forensic scientists growing world wide it also offers an incredible opportunity for travel.

Elementary Science Fair Projects - Growing Crystals


In this elementary science fair project we are going to look at crystals and we are going to try and grow crystals. In nature we find crystals in all shapes and sizes. We get ones that are considered valuable, like diamonds, and others that are not considered so valuable. All crystals have their own quality and are beautiful. Crystals are easy to grow and are therefore a very suitable elementary science fair project.

The definition of a crystal according to the Oxford Dictionary:

A piece of a homogeneous solid substance having a natural geometrically regular form with symmetrically arranged plane faces. Chemistry: any solid consisting of a symmetrical, ordered, three-dimensional aggregation of atoms or molecules. A clear transparent mineral, especially quartz.

For our elementary science fair project we are going to grow crystals in a gelatin solution. Because heat is going to be used, this science experiment should be done under adult supervision.

What you will need for this experiment:


A 1-pint glass jar
A ¼ cup of table sugar
A ½ Cup of distilled water
0.25 ounce of unflavored gelatin
A small saucepan
Spoon

The method for this elementary science fair project:


First you have to pour the water into your saucepan.
Now you sprinkle the gelatin over the water and allow it to soak for a few minutes.
Place the saucepan on the stove and heat the water while you are stirring to dissolve the gelatin completely in the water.
Continue stirring while you add the sugar.
Continue until the sugar is completely dissolved in the water.
After the solution (what is a solution?) has cooled down for about 5 minutes you have to pour it carefully into your jar.
Now you have to leave the jar undisturbed for at least two weeks.
Make daily observations and write them down carefully.
It might even be a good idea to take photos of your elementary science fair project every day to use in your display. Remember a good display is almost as important as the experiment!
Take note that more than one thing happens at a time with this experiment. What are the two things?
Why is it happening?

If you did this elementary science fair project right, the gelatin in the water will cause the water to set. (Think jello!) The other thing that happens is that after a few days clear crystals form inside the gel and it appears to be suspended throughout the gel. Remember to take photos every day to show how the crystals grow bigger and bigger every day. You can also draw charts to show how the crystals are formed throughout the gel.

Now you also have to be able to explain why it happens:

As you heat the water, more of your solute (that what is dissolved in the water) will dissolve in the water (called your solvent) as would have when the water is cold. Now when the water starts to cool there is more sugar dissolved in the water than would normally have been dissolved in it. Now we get what is called a supersaturated solution.

Now, as the water evaporates your solution becomes even more supersaturated and it becomes unstable, now any disturbance will cause the microscopic molecules of the solute to stick together and form crystals. At first the crystals are too small to be seen but, as they grow they become bigger and visible as they form clumps throughout the gel. The reason for the gel in your elementary science fair project is to keep the crystals suspended and thus ensuring that many crystals form.

For an even better elementary science fair project you can do more than one experiment. Repeat the above but change some of the conditions. See what happens of the solution cools down slower by maybe placing your jar in a big thermos flask. You can also use a bottle with a narrow mouth instead of the jar and see if the slower evaporation of the water makes a difference. You can even make a solution with different kinds of sugar such as sucrose glucose and fructose and see what happens then. The possibilities are endless and this elementary science fair project can be as simple or as involved as you would like.

Food Science Programs Focus On Good Nutrition


We've all heard the old adage "You are what you eat," and food science programs prove the point in spades. An education in food science can make you an expert on food and nutrition, and help you qualify for employment with food manufacturing companies and food retail outlets, as well as for producing various foods.

Food science courses integrate and apply the subjects of chemistry, engineering, biology, and nutrition to the curriculum's. Food science schools teach matters relating to food preservation, food processing, food packaging, and food distribution. Subjects also include nutrition, as well as the health benefits, safety, and afford ability of foods.

Students enrolled in food science programs can anticipate focusing on the physical and biological properties of food and its chemical values, nutritive values, and much more. Students will also learn about plant and animal chemistry and biology.

Advanced degrees in Food Science require specialized studies in food chemistry, microbiology, toxicology, engineering, or nutrition education. A bachelor (BS) or master degree (MS) in Food Science can qualify the graduate for positions in administration and programs, as well as research institutions and government agencies. Other positions can include areas of quality management, food processing, food research and development, and marketing and distribution of foods in the food industry. Professionals in the culinary industry or restaurant management can also benefit from a program in food science.

There is an increased demand for qualified food science experts in research, industry, and government. With current concerns about contamination and genetic modification, the career possibilities are excellent for those with comprehensive food science training. There are many educational avenues from which to choose, including vocational schools, colleges, universities, and even distance learning and online schools.

In summation, a graduate with a degree from an accredited of food science program will find that jobs are varied, plentiful, and offer excellent salaries. Incomes for graduates with BS degrees in Food Science can begin at $48,000; graduates with MS degrees may earn $55,000 or more in their first year.

The Transformation Of Political Science And The Rise In Crime Rates


The current field of political sciences is dominated by a multitude of ideas that have never in its history featured so prominently in this discipline. The general belief that it has lost its focus once and for all is from time to time counteracted by different opinions. One of those is that the world has come full circle, that mankind has experimented out all possibilities in terms of ideological thinking and that the liberal democracy as we know it has come out of the process as the prize winner both politically and economically. Some define this as the end of history. It also goes by the name of ultra modernism. Globalisation fits in perfectly and all reflects the increasing complexity that we are finding our world to involve us in and which, in order to come to terms with the bigger magnitude of the whole, we are describing in essentially vague terms.

The idea that history might have died a death was first launched in the 1980s by Francis Fukayama who wrote a now famous essay entitled 'The End of History', in The National Interest on the subject. The idea has persisted during the subsequent historic reality-altering events leading to our understanding of the world in terms of security and globalization, even though the liberal ground is under siege from left and right wing ideologies, parts of which are finding their way into the democratic liberal discourse.

However inappropriate it essentially is to define the new 'winning ideology' -- the policical science discourse is rife with arguments in favor of departing from old fashioned foundationalism and swapping this for a-systemic ideas gathered from all other disciplines-- we are at this time almost as happy with any theory that offers a firm grip on reality as the third world would be with a cure for poverty. Much though the world is changing and much though this fast change is reflected in the sciences, the a-systemic ideas making up the political sciences might not necessarily reflect what's going on in society one hundred percent adequately.

Issues like crime and other 'anti social behavior' are significantly underexposed in areas of political scientific studies, say researchers. Our highly developed society and increased sophistication in all the disciplines that results in political sciences being a highly esteemed area for study, delivering no doubt high caliber students to society, does not necessarily guarantee a tangible decline in crime rates. We are missing out something big time. Is this the whiplash of a-systemic thinking we all intuitively fear?

If you may believe studies undertaken by political scientists, in future, we won't have a lot of room for corruption and evil wrongdoers in our society. Leaf through an average new book on political science and find hardly a line, let alone a chapter, dedicated to the evil side of human nature. What makes us all think that synchronising everything automatically leads to a better world and therefore a less violence prone society? In the same breath, you might ask, what is the new Left, the new Right, the Libertarian and the other political mainstream thinking on issues such as the Third World? For all our great knowledge and speedy technology-supported understanding of what is going on, we are still not much better at remedying the main problems the world is faced with.

Criminology is part of the exercise of deconstructing the past, deconstructing other disciplines and constructing new ideas from a mixture of all of them which keeps social scientists busy these days. Yet it's not enough apparently to translate into better thinking on the way safety and society can be organised.

Whether a certain approach to crime really is to blame for its rise is debatable. What is certain is that modern societies have become safer and more comfortable in many areas but that crime has risen in equal proportion. "When it comes to crime, or more broadly stated 'antisocial' behaviour, society has actually become less safe. Crime constitutes an insecurity risk which is difficult to control. Many citizens and organizations will at some stage fall victim - usually completely unexpected -to behaviour which can harm them, physically or financially", according to a recent research report by the Foresight Institute of the Netherlands, a semi official consultancy. It is one of the few studies in this field.

The increasingly Old World definition of the nation state was primarily driven by the desire to resist this sort of danger, the researchers say. They continue that the way we deal with crime has evolved too. It is at this point that state organization is likely to really begin to crumble. A prime, if not the prime raison d'etre for governments is keeping a population relatively safe and free from crime. The more governments are perceived to be failing in providing the desired high level of societal safety, the less justification there is for governments and their imposing taxes on a country's population.

Changes in the way crime is perceived include treatment of the issue in more scientific disciplines than ever. Yet some, including Fukayama, argue that the social sciences lack a distinct central view on human nature, which stems back from the post Kant era. The only reason that I feel you can raise the human nature argument again is that over the last 30 years in the life sciences there has been a lot of empirical work that has made the concept respectable to scientists. Yet social scientists and certainly people in cultural studies have yet to get that message, says Fukayama. They are very resistant to the notion of human nature.

The issue is grappled with mostly by people who try to integrate crime studies into a whole range of disciplines. "Crime has lost its exclusiveness, the approach to crime and crime prevention is no longer exclusively the responsibility of the police and the judicial authorities", say the Foresight institution researchers. This coincided with a tangible change in society too. In the early 1980s, there was a sea change in the approach to crime and crime prevention. Inspired by understandable self-interest, individual citizens, organizations in the community and local authorities started to feel that they bore a responsibility for crime prevention. Nevertheless, the results are not particularly overwhelming and the researchers at Foresight say that for the situation by the year 2010, some areas of research are still vastly underrepresented.

One real life example of high profile people sharing this concern is the situation on the Guernsey islands off the coast of the UK. You'd say this small island offers a perfect case to study the governability of a country with a limited population, to try and test the limits of a system to the full. Politicians might well be aware of this. At least, they appear to have a clear idea and are aware of the unique nature of their society and of the effects of the rules they invent. The measurability of crime renders the subject a good target for analysis, sophisticated ideas of governance and societal structures. The self consciousness leads to frequent interesting debates by politicians on this island. Recently, a senior politician attributed the perceived rise in crime and anti-social behavior the effect of "woolly liberal" thinking. He said the increased emphasis on human rights in particular is to blame for the rise in crime.

The politician said that his government's human rights act had led to offenders becoming "untouchable" by the authorities. Warning of the dangers of liberal thinking, he pointed out that there's no common sense in Guernsey's human rights laws which others believe ensure rights and responsibilities of citizens are balanced out rather evenly. He said the woolly thinking underlying the human rights ideas on the island led to alcoholism among the younger population for one.

This is one of the issues where the argument that improved technology in the hands of police and law enforcers is going to do the trick, won't do completely. Developments in modern technology and improved understanding of changes in social control are central to ideas about stamping out crime. The foresight researchers recommend that there should be a radical reorganisation of how financial resources are made available to this effect, if crime prevention is to bear any fruit.

Research efforts need to be stepped up dramatically if modern society is to develop adequate knowledge in any form or shape. They believe that the demand for scientific knowledge by the institutions, municipalities, government departments and private sector agencies might seem to be a professionalization of the area, but that in fact it does often not mean anything, especially not in the long run.

Fundamental scientific research into issues which are already playing a part at this time needs to be stepped up, the institute believes, in order to keep up with the criminal sector. They predict that by 2010, crime will have changed radically as a result of technological and economic developments and changes in social control and cohesion. There is a great need for fundamental research, for interdisciplinary knowledge and knowledge about long-term, ongoing issues such as criminal careers, say the researchers. In the next ten years there will also be a need for more theoretical research focusing on normative and empirical issues.

The wildly diverging ideas about human beings in the social sciences is exacerbated with a dramatically lowered emphasis on any blatant negative aspects of society in postmodern political science due to the death of positivist thinking. You could argue that this is at the heart of the problem of surging crime despite increased wealth of societies.

The political sciences appear most promising in their capacity for addressing the anomalies. It is the best discipline to do so, because it does not plan at neutrality. And, what's more, the political scientist´s loyalties and engagements will not necessarily be predictable and stable over time. If it doesn't yield immediate tangible results, it at least is a start. And it makes for less dry reading of the articles and books describing what's perceived as the state of play in these sciences. You'd imagine that anyone coming up with a theory involving the axiom that history has ended, would be prone to fantasy.

And that's somewhat true; academic attention for total fantastic ideas as a means to understand or create is on the rise. It's much under attack from critics who say this is a foolish activity, especially when keeping in mind the idea that when you walk the streets of your town you can be subjected to a criminal attack at any given moment. Sceptics will imply that much of the storytelling anyway misses out large parts of reality, especially the less attractive features. Which is, however, not to say that blind spots are not being reduced.

But somehow, the rationale itself is changing for the criticism of the ways modern science works. The criticism for instance on the way politicians work, who seem keener to know about the cultural trends, popular culture, the media and power than in the labyrinthine workings of party and parliamentary democracy is that they are not sticking to their own field. Yet the new approaches favored in the political sciences leave more leeway for alternative ways that allow for a greater number of methods to assess reality than many predecessors ever dreamt of.

In stead of a total abandonment of all serious work, modern political science presents us with a mixture of both regurgitated theories of old time philosophers and original, rather broad based ideas. And in new, often surprising, ways.

Sceptical post modernists will contend that as there is no correct method for political research and researching the political, that it might be wise to adopt an anti-rules method, while the affirmatives may adopt something that can be termed 'anything goes'. But perhaps several methodologies are best blended together to come to a robust approach to researching a problem. Much hinges too on one's perspective on history.

Science Fair Project - 9 Must Know Tasks To An A Plus


It is that time of the year and your teacher hands out a piece of paper to take home that states the next class assignment is a science fair project and is due in a few weeks.

You may have already picked out a project to do but if not try all the following steps:

1. Originality Is Key!

Your teachers or whoever judges the science fair projects will look for new ideas that are being presented to them. They do not want to see the old stale information from last year. You could definitely think of something that could fix a problem you have in your house or with a product.

2. Prepare

Now that you have the idea it is important to do the project good and you will not do it well if you do not prepare first.

3. Project You

This is one of my biggest pet peeves. The kids come home and hand their parents the paper and expect their mom or dad to give them an idea, get the materials, set up the experiment and do the project. They tell their child what happened and give them the experiment to take to school. No way! This is why you are doing a science project to learn something about science and what better way than to do the experiment yourself.

4. What Are You Doing?

If you have a good idea does your project have clear cut steps to prove your theory? If not you may just be treading water. Keep it simple and understandable and make sure it solves a question or solution.

6. Do You Know It?

When you present the experiment and its outcome to your teacher are you knowledgeable? If they ask a question can you tell them the answer without being goofy? You need to know the information about your project. Your teacher will be impressed and you will actually learn something if you truly know everything about your science experiment. Make sure to do a project that you will be able to understand. If it is really complicated and you still do not understand the concept when you are done then maybe it is too old for you. You need to understand the science level you are trying to accomplish.

7. Answer The Question

Did you answer the question you determined in your hypothesis? If you have shown a science project make sure it works and proves the hypothesis or disproves it.

8. Documentation and Evidence

Give all informational support about the answer you generated in the experiment. You have to prove what you are saying and doing is correct so have back up information to show them.

9. Do Something You Like and Put Yourself Into It

You need to pick a topic that you like and put enough time into the project. If you quickly jot down the science information it will show so pick something you like and will spend time doing and researching to prove a point. Your teacher will see your hard work.

Hope your next science fair project is successful when you follow these steps.
