Environmental science issues are hot button issues in the news right now. Everyone from the Federal government to small businesses are talking about how the environment needs to be addressed. The importance of the issues related to this field of study make it a critical subject to teach children about.

Local Environmental Issues

There are many environmental science issues that can be taught to children. However, the ones that will have the biggest impact on their education will be the issues that are currently impacting their lives. For example, local environmental issues related to pollution, toxins and even local climatic changes are all great topics to teach kids about.

Local environmental issues are easy to cover in science curriculum. They are generally covered in local newspapers and on local news broadcasts. Local environmental issues can also be directly studied by science students. For example, students can visit local factories to see how they are modifying their activities to reduce pollution that they cause, or students can take water samples from local rivers or streams to test them for pollutants.

It is important for kids to learn about local environmental issues because these issues are currently impacting their lives. This makes the issues topical and more interesting to kids. They also help to show science students the link between environmental science and their lives.

Global Environmental Issues

After covering local environmental issues it is important to expand the discussion to global issues. These global issues are important to study because they impact everyone on the planet. Global environmental issues are covered extensively by the media as well as by science textbooks.

When studying global environmental issues it is important to approach the material in stages. A good way to start the discussion about global environmental issues to learn about what the issues are. Introductory lessons will cover the main components and facts of each global environmental issue like global warming and the desalinization of the world’s oceans.

The next step will be to review case studies of each global environmental issue. Case studies will provide students with more insight into the issue being discussed. This insight can be developed through classroom demonstrations and experiments that utilize science fair kits. These experiments will give kids first hand experience manipulating variables that are related to the issue being discussed.

The final step will be to link the global issue to the local environment. This can be done in several ways. First you can identify an example of the global issue in the local environment and secondly you can determine what would happen if the global issue were to impact the local environment in a dramatic way. Students can develop their own scenarios of what would happen if the local climate, for example, increased its average temperature by two degrees Fahrenheit.

The study of the effects of human activity on the world is a critical one to conduct. Knowing how humans impact the world provides valuable data that allows humans to moderate their behaviors in order to create desired outcomes. However, just knowing how humans impact the world is not always enough to protect the world from harmful human activities.

Effects on Science

Human activity has long-lasting effects on science. First of all the search for knowledge, which is the basis of science, is a human invention. Therefore the most dramatic impact that human activity has on science is its creation.

The second long-lasting effect that human activity has on science is the evolution of scientific knowledge. Each year humans conduct experiments and research in order to learn more about specific topics or to test new ideas about how the world works. As humans learn more about how things work they manipulate these facts to see if they can be altered or changed. The changes that are manufactured change scientific reality.

One of the most influential components of human activities on science is scientific imagination. Many theories in obscure and abstract science fields are based on realities created in the minds of scientists and researchers. These alternative realities allow humans to manipulate science concepts and bend the facts of the universe to create amazing new discoveries.

Effects on Society

Human activity is shaped by society and society is shaped by human activity. This reciprocity allows societies to evolve with the evolution of humans. This allows societies to provide humans with the structure and support needed to function in an effective manner.

On the other hand, sometimes society’s evolution does not keep up with the evolution of the human experience. As a result social turmoil develops. Social turmoil can be demonstrated by revolutions, protests and social unrest.

Eventually, as a society realigns with modern activities a social equilibrium is again reached. This is when societies are at their most productive. Unfortunately, this equilibrium is usually short lived as human activities evolve at a much faster rate than societies do, and human activity evolution is experienced in bursts as opposed to steady flows of change.

Conclusion

Human activity has long-lasting effects on science and society. Human activity can lead to positive changes in both science and society, such as the development of robots and robotics that reduce human exposure to hazardous materials. Unfortunately, human activity can also lead to negative changes such as the development of social injustices and environmental degradation.

Sports science fair projects are a great option for science students that just can’t get excited about completing their science project. This option gives middle school athletes the opportunity to learn about the science behind their favorite sport. This helps to not only motivate the student to do well on their project, but it also helps to make completing a science fair project much more enjoyable.

In order to develop a science fair project that relates to sports the student needs to first select a sport to study. This sport can be one that they participate in or one that they just enjoy watching and learning more about. The most popular sports used for sports science fair projects include: swimming, hockey, volleyball, football, basketball and running. However, more obscure sports are also valid options.

After selecting a sport to work with the next step will be to isolate one aspect of that sport to study. For example, you can examine the physical characteristics of the equipment used by the sport or you can examine the body mechanics of an athlete in the sport that has been selected. It is important to select only one element to research in your science fair project.

Step three is to learn about the element that you have isolated. This will be done through background research. Students will want to read everything that they can get their hands on about their subject. During this process the student needs to take notes and they will need to create a bibliography.

When the student has a good understanding of their project’s topic they will be ready to develop a hypothesis. The hypothesis is a prediction that the project will try to prove or disprove. It will compare two variables, a dependent variable and an independent variable. An example hypothesis for a sports project would be something like, “the height of a football’s profile impacts its aerodynamics.”

Step five is to design an experiment that tests what the hypothesis states. Using the example hypothesis from above an experiment can be designed by testing the aerodynamics of footballs with various profile heights. Obviously some hypotheses that students develop will turn out to be false. This is okay and it doesn’t impact the value of the project. The goal is to either prove or disprove a hypothesis and the discovery of false hypotheses is just as valuable as discovering hypotheses that seem to be true.

It is important to continuously evaluate the design of your science fair project. Many students will find that their experiment has flaws as they collect data. If a flaw is discovered in an experiment’s design the student will need to fix the problem, discard their corrupted data and collect new data using the revised experiment design. When flaws are discovered and corrected the student needs to note it in their report to show that they caught the problem and corrected it. This will impress the judges.

Data collection is one of the most critical and one of the most difficult parts of completing a sports science fair project. It can be difficult to collect accurate data when working on a sports field or when working in a collection environment that is difficult to control. However, you can improve your data’s reliability by using the right equipment. Common equipment that you can use to collect data for your project include: stop watches, video cameras, digital cameras, heart rate monitors and even student’s microscopes.

Botany science fair projects are very popular with science students. This is because they are easy to set up and because they are generally a low cost project. However, botany science fair projects can be boring if you do not take an innovative approach to their experiments’ designs.

Innovation and Botany Science Fair Projects

Innovation is a key element to developing a winning science fair project. Innovation can be achieved by applying a basic experimental design to a unique testing environment or by manipulating the components of a classic plant experiment or by creating a completely new botany experiment.

Innovation can also be achieved by solving a new problem related to botany or to some other field of study. For example, you may want to develop a project that focuses on how fertilizers impact different types of soils or how they react in different types of climates. It is important to think outside-the-box when developing a botany science project.

To develop an innovative botany science fair project you will want to first focus on selecting a plant that will grow fast enough for you to collect data on. Secondly you will need to focus on a specific growth component to study. Finally you will need to find a unique angle to approach your project’s problem from.

Do Different Types of Fertilizers Affect Plant Growth?

One commonly asked question in botany science fair projects is whether or not different types of fertilizers impact the growth rate of plants. This question, while common, can be used to develop an innovative science fair project. However, you will need to be creative in your approach to answering it.

The first thing that you will need to do is to figure out a unique angle to this problem. For example, you can approach the problem by experimenting with fertilizers with different chemical formulas, or you can approach the problem by experimenting with both chemical and organic fertilizers.

The easiest way to develop an innovative botany science fair project that explores the effectiveness of fertilizers is to increase the scope of the study. Instead of just focusing on how fertilizers affect the growth of plants in one type of soil, you can also test the effectiveness of fertilizers in a variety of soils compounds. This will give you a much deeper understanding of how specific fertilizers impact plant growth rates. It can also help you to identify other factors that are impacting the growth rate of the plants that you are studying.

Conclusion

Fertilizer and botany science fair projects are usually going to be completed by younger middle school science students. However, older students can also work with this topic, as long as they expand the scope or depth of the study. This can be done by using science fair kits that include soil testing tools and supplies to collect more data about their test subjects. This added data will allow the student to produce a better foundation for their findings and conclusions.

There are many components of an experiment’s design. However, one of the most underplanned elements of a science fair project’s experiment is the control experiment. This is a huge problem as the control experiment generates the baseline data which you will need to use to base your findings and conclusions on.

Designing a Control Experiment

A control experiment is going to have the same basic design as your test subject experiments. The only difference is that the control experiment will not be manipulating the independent variable. Instead it will use a neutral independent variable.

Finding a neutral independent variable for your control experiment is going to be challenging for some experiments and easier for others. When conducting a solution based experiment water will usually be the control experiment’s neutral independent variable. To find a neutral independent variable for your control experiment you will need to make value judgments as to what is the “normal” conditions for the situation being tested. For example, if you are testing electrical resistency in your experiment a neutral independent may be copper wire, as it is commonly used in household wiring projects.

If you are working on a renewable energy science fair projects then you will need to design your control experiment around what is commonly being used. For example, if you experiment is testing the power generation properties of a wind turbine then your control experiment will need to be set up based upon what you want to compare the power generation properties against, such as those of a fossil fuel powered turbine or a hydro powered turbine. You will need to define your baseline data source and this definition will be used to create your control experiment.

Collecting Control Data

It is important to collect data from your control experiment first, before working on your test experiment. This will produce several advantages. First it will help you test the design of your experiment and secondly it will provide you with an uncontaminated set of data to work around.

To get the most reliable data possible you will want to run your control experiment several times. This will help you to determine if your experiment’s design is effective and it will also help you to create an average control data set. To average data set will be created by adding all of your data values together and dividing by the number of experiments that you ran.

After you have your data in hand you will need to organize it. Organization of data is usually best done in a spreadsheet. A spreadsheet will allow you to both keep your data organized in one place and it will also allow you to quickly analyze it later on.

Conclusion

Developing a control experiment for a science fair project is the first thing that you will want to do when working on your project’s experiment design. The control experiment will be exactly like your test experiment. However, instead of using an independent variable you will be using a neutral independent variable.
