How To Develop A Science Fair Hypothesis


Science Fair Hypothesis

Younger students will often participate in science fair by presenting a science experiment that has a predictable result. That is, these age groups will follow instructions and use commonly found materials to demonstrate a fact or interesting tidbit about the nature of biology or chemistry. Older students, however, have advanced beyond simply using experiments that have already been done thousands of times before. At this age they will often be required to develop a science fair hypothesis and take all the necessary steps to prove or disprove that hypothesis. This requirement is designed for the older students because they have developed the learning and thinking abilities required for analysis and application. These higher order thinking skills are used to develop the science fair hypothesis and put that hypothesis to the test.

A science fair hypothesis can be developed around any topic related to science. One of the most popular science fair hypothesis categories currently being explored by older students is in the environmental arena. Many students are developing their own creative science fair hypothesis in order to address the concerns of environmental issues. While these topics decreased for a while, they are making a strong comeback, as students want to research a science fair hypothesis that will have a positive impact on the health of the planet. Many of these science fair hypotheses are developed by students at the high school level as an attempt to discover solutions to issues such as pollution, clean water, greenhouse gases and other problems we are facing on the environmental front. The current student body of budding young scientists is very motivated and interested in issues on this topic.

A science fair hypothesis surrounding the need for solutions to our even increasing concern for the health of the planet is one from which we all benefit. While the adult world may view these science fair projects as kid stuff there are others that will seriously consider the findings of these young scientists. Scientists currently working in environmental fields judge many of these science fairs. They are in search of the creative minds of the future generation in hopes of encouraging them to continue their work in testing a science fair hypothesis. What begins in school may just be the solution to our ecological problems on the planet.

Do Bar And Ring Magnets Have Different Magnetic Properties Science Fair Project


Magnets are a common test subject for elementary and middle school science fair projects. Magnet science fair projects often examine what impacts a magnetic field or what a magnetic field can impact. In this sample project students will be examining if magnetic properties can be manipulated based on the type of magnet, ring or bar, that is used.


The hypothesis for this science fair project is that the ring and bar magnets have the same magnetic properties. The dependent variable for this hypothesis is the type of magnetic properties that are displayed by the magnet and the independent variable is the type of magnet. To clarify this hypothesis the term magnetic properties needs to be defined as having a magnetic polarity.


To complete this magnet science fair project students will need a variety of bar and ring magnets. They will also need to have objects that also have polarity such as metal objects. Finally, students will need a data collection sheet.

The Experiment

The control experiment for this test will use the bar magnet. This magnet was chosen because it has the most traditional shape and properties. It will serve as the baseline data source. To test the magnetic properties of a bar magnet students will need to test the bar for polarity by identifying if it attracts opposite poles and if it repels like poles.

The test experiment will focus on the ring magnet. This magnet will be run through similar tests. A bar magnet that has poles clearly labeled can be used to test the polarity of various points on the ring magnet. Students will want to mark what areas of the ring magnet are attracted by each pole of the bar magnet and which areas are repelled.

Data Collection and Analysis

The collection of data will be based on simple observations of repulsion and attraction trends for both the bar and the ring magnets. The analysis of the data will revolve on the students ability or inability to find poles on the ring magnet. (*Hint: the poles on a ring magnet may not be found on the curved edge of the magnet.)

In order to prove the hypothesis may be correct the student will need to find polarity properties on the ring magnet. If polarity is not found then the hypothesis can be assumed to be false. Students may need to run this experiment several times to gather enough data to make a solid conclusion from the data that they collect.

Design A Water Filtration System For A Science Fair Project


One of the perks of working on a science fair project is that you are completely free to explore your topic. You can examine any element of your topic that you want and you are only confined by your understanding of the topic and your imagination. One of the challenges of working on a science fair project, on the other hand, is that you are often required to design and build testing equipment, processes and tools. This article will show you how to design four different types of water filtration systems for your science fair project.

#1 Shampoo and Newspaper

One of the most simple water filtration systems that you can design and build is a shampoo and newspaper filtration system. This system will not only filter out sediment from your water sample, but it will also remove contaminants like oil, pesticides and other oily substances. To create this water filtration system you will need a stack of newspapers, shampoo and your contaminated water.

First create your newspaper filter by laying several pieces of newspaper over a bucket. Next spread a layer of shampoos on the surface of the newspaper. Finally, slowly pour the contaminated water over the newspaper filter. The water will be cleaned by the shampoo and filtered by the newspaper.

#2 Mini-Earth Water Processor

The second option that you have is to create a miniature version of the earths water filtration system. For this you will need a five gallon bucket, plastic hosing, large stones, medium sized stones, cheese cloth, gravel and sand. You will also need a tool to cut a hole in the bottom of your bucket.

To build this water filtration system you will cut a hole in the bottom of your buck large enough to fit the hose and a rubber stopper. Thread the hose through the hole and secure it with a rubber washer. Next line the bucket with finely woven cheese cloth, gauze or burlap. Make sure the fabric square is large enough to line the entire bucket and to hang outside the bucket. Add a layer of sand, then pea gravel, then medium sized rocks and finally top it off with larger stones.

Place your bucket up on a table so that the hose hangs down and comes to rest in normal bucket on the floor. Pour the contaminated water into the filter bucket and allow the water to be processed. The clean water will be collected in the second bucket.

Teacher’s Guide To Science Fair Projects – Scientific Questions

Developing a lesson plan for science fair project units is easy to do. To start with you need to focus on a specific skill that is used for science fair project development. In this lesson plan you will be focusing on the utilization of scientific questions to come up with a topic for a project. This is one of the first lesson plans that you will need to develop for your science fair project module.

Goals and Objectives

Every lesson plan needs to start out by identifying the goals and objectives for the lesson plan. In this case the goals and objectives will be to introduce the concepts of scientific questions and project topics. After completing this lesson plan students will be able to come up with their own scientific questions and they will also be able to use their questions to select a topic for their own science fair project.

Introductory Information

At the beginning of your scientific question lesson you will need to introduce them of asking scientific questions. This can be done by first playing a round of 20 questions. This game is a great primer for what the students will be doing to find a topic for their science fair project. After playing the game of 20 questions you can talk about how scientists use questions to identify what needs to be researched or what angles you can take to find solutions to a scientific problem. Make sure you provide specific examples of scientists and the questions that they asked.

Guided Study

The next step is complete a guided study project. This activity will involve a series of 5 minute brainstorming sessions where students will be asked to come up with s many scientific questions as possible about a topic that you give them. For example, you may give your students the topic of renewable energy and have them brainstorm questions about this topic for five minutes. After each session you will write down the questions on the board to show how many different questions can be developed for one topic.

Homework Activity

For homework, you will ask each student to select a topic and to come up with 15 to 20 questions about that topic. These questions will be used to come up with a topic for the student’s science fair project in a later lesson.

Modern Technology In Sports

What is it about sport that makes it so attractive to people? Is it the adrenaline rush of competitive and/or dangerous sport? Is it the feel good factor of recreational sport; is it the opportunity of socialising with others, or perhaps all of the above? Whatever the reasons may be, sport is certainly getting more and more popular, especially in the developed world.

A major factor in the popularity of sport is the role of modern technology. Improvements in modern technology have resulted in better playing conditions and equipment for players as well as greater viewing pleasure for spectators.

Perhaps the greatest changes have taken place in the designing of sporting facilities – such as modern sports surfaces and improved artificial lighting that offer increased opportunity to play. Modern sports surfaces are low maintenance, therefore low cost, and allow year round use. Professional technical expertise is needed to design and install a modern sports surface. Properties such as its rebound resistance, slip resistance, and shock absorption are measured to ensure that the surface is going to provide optimum playing conditions for that sport, whilst giving players ease of movement and adequate protection from injury. Regular maintenance of sports surfaces, both outdoor and indoor is recommended to ensure safety of players.

Along with an increased number of players there are also an increased number of viewers all over the globe. With the spread of satellite TV, events in one part of the world can be watched real time, in another. Modern flood lighting has not only allowed greater use of sports facilities at the recreational level, but also made possible higher-level competition fixtures such as day-night cricket matches, night-time football matches etc. Electronic score boards, photo-finish timing devices, slow motion replays and large viewing screens have also added to the viewing pleasure of spectators.

Modern materials are used in the manufacture of synthetic sports surfaces as well as sports equipment. Third generation synthetic grass is made from polymers and provides a maintenance free all-weather surface for sports. The use of composite materials makes sports equipment such as rackets and protective gear, lighter and more durable, enabling athletes to further improve their performance. Advances in modern technology have also led to improvements in the design of sports equipment such as trainers and sports shoes, starting blocks for use in athletics, pole vaults etc.

Whilst it is difficult for the average user of sporting equipment to keep up with the latest developments, as a guide in the UK sports equipment and sports facilities and surfaces should comply with British standards. Some governing bodies of individual sports also offer certification to demonstrate compliance with international standards.

Bike Sailing 21st Century Innovation Or A Science Project Gone Bad

With ozone-layer depletion a great issue nowadays, inventors are developing new ideas. The transportation sector in particular is getting all the bad publicity. And as carbon monoxide emissions become the focus of tighter regulations both in the US and Europe, the race for eco-friendly vehicles is on.

One of the inventors who rely on the powers of Mother Nature is Vladimir Zam. His wind-powered bike is designed with a triangular sail. The big question is: how will the bike run?

The design for US Patent 6932368 calls for a sail attachment to be linked to the bicycle harnesses wind to move the bicycle forward. A wind receiving sail is available at the attachment, which can generate the wind needed to power the bike.

Would the addition of a sail attachment qualifies it an invention? It looks more like a science project gone bad. Seriously, the design for this patent is an awkward cross between a sail boat and a bicycle. Considering that the patent retains most of the features of a regular bike, the sail attachment just complicate matters. Whereas, people could simply rely on their two feet to forward a bicycle.

Imagine yourself driving this thing around in the middle of the metropolis traffic jam. That is provided you could survive peddling a long the streets without being dragged through your sail by speeding vehicles. On the upside, well you could make money using this bike to money. For instance, why dont you convince your local pizza delivery store to advertise on your sail. Youll just have to capitalize on your endurance and be able to bike for three acres or until you drop dead, whichever comes first.

So what do you guys think? Is this an innovative invention or just a product of a man having too much time on his hands?

What To Take Into Consideration In The Video Conference Technology
