How to Choose the Right Type of Science Fair Project

Saturday, November 28th, 2009

Science fair projects can be the most memorable part of your science class, giving you an opportunity to show your abilities and creativity. But for many students, one of the most difficult steps is just getting started. As a first step, make sure you understand the different types of science fair projects. Take the time to choose the right type of science fair project, so that your time and effort are not wasted doing the wrong things.

There are three different methods you can use for science fair projects: building (or modeling), demonstrating or investigating. When picking among them, there are two things to consider. First, read the science fair rules to find out what type of project is required, and be sure to confirm it with your teacher. Second, if you have a choice, pick the type that will enable you to show what you’re best at.

The Model Building Method

The model building method is the kind of project which, as the name implies, enables you to construct a model, to scale whenever possible, to illustrate a specific scientific principle. This could be as simple as a model of the solar system, or a real working machine. Many of us have seen the model of an erupting volcano in which the chemical reaction between baking soda and vinegar causes realistic looking ‘lava’ flows down the sides of a ‘mountain’. Building models is a lot of fun, but don’t expect it to win your high school science fair. Models are most often used in elementary school fairs. Some students do create unusual or dramatic models, which can be used demonstrate new ideas.

The Demonstration

The demonstration or descriptive method of research is again fairly self-explanatory. Here, you might display a collection of objects or interesting artifacts (for example, your rock collection) connected with a topic (geology) and describe them in detail on your display board, or in your report or speech. As an alternative, you could use a visual project display board to describe the research you performed. When you do this kind of project, you are not doing anything new, but only explaining or illustrating known scientific principles.

The Scientific Experiment (Investigation)

It is with the third of the possible methods that you can provide what most science fairs for older students are looking for – proper scientific experiments using scientific methods to construct and test a hypothesis and draw conclusions from it. If you are interested in a science career, or would like to move on the regional or national science fair, then you should be looking into this area. And the choice of science fair project topics is limitless. Biology, chemistry and physics projects are common, but if your interest lies elsewhere, consider geology, environment, meteorology, or even sports science. Develop a hypothesis around your interest, and then find a method of testing it. Books and web sites can be valuable sources for project ideas, but the more novel and distinctive your project, the more interested the judges will be.

Remember, it is important to keep your teacher informed about your progress, and confirm that you know the rules and requirements for your science fair. Then, no matter what science projects you choose to do, you can enjoy the experience, confident that you have chosen well!


Backyard Science Projects

Wednesday, July 1st, 2009

Your yard and neighborhood provide many wonderful opportunities for kids to both play and learn.  In addition to swimming and other outdoor sports, your child can also use your backyard for science projects. If you are interested in helping them achieve this, you may want to familiarize yourself with some popular backyard activities, especially those that have a focus on nature and science.

Exploring the outdoors is not only a fun activity, but it can also provide many educational science experiments.  There are a surprisingly large number of different plants and living creatures that can be found in your yard or near your home, even in an urban environment.  Most children love exploring nature, especially with your encouragement and help. This is particularly true with toddlers and elementary school aged children. Choose activities that you enjoy, because your kids will require your help.

One way for children to learn science is by examining the local plants. You can find many different species of plants in your own backyard – some of them planned, and others unwanted. For the best type of environment, you are encouraged to explore areas of your yard that have yet to be mowed.

You can find many habitats for the different animals and birds in your backyard. Try to identify as many different kinds as you can. Be patient and quietly observe them for awhile. What do they eat? Can you find their homes? Bird watching is a popular hobby, and even amateur bird watchers often contribute to real science projects. If your child really enjoys it, they may ask for a new pet.

You can also find many different kinds of insects in your yard. Children may find observing bugs even more interesting than studying the plants and flowers. It is both fun and educational to study the types of insects that are in your yard.

Encourage your child to study the impact of the weather on the environment for the plants and animals in your yard. Backyard conditions change as the weather changes. Study your backyard after a heavy rain, and have your child look for all the changes they can find. Weather plays a big role in the lives of the plants and animals living in your backyard.

Providing your child with some basic scientific supplies can reinforce their learning experience. These supplies may include, but should not be limited to containers, butterfly catching nets, magnifying glasses, picture books, and resource guides. Many kids like to catch insects to observe them more closely, so poke some air holes in a jar or get a small cage. You can buy these supplies at many stores, such as toy stores, department stores, or sometimes even dollar stores. Or find what you need by searching online.

Nature and science books may be a good addition to your child’s library, as resources they can turn to again and again. Many books and guides have a specific focus on insects, birds, plants, or flowers.Use the pictures and information in the books to identify the plant and animal species you find. For a large selection of science and nature books, you are encouraged to shop online or visit your local book store.

Encourage your child to document the animals, birds, insects and plants they discover.  This can easily be done with a notebook or a camera. By taking pictures, your child will always be able to remember their exploration adventures.  Those pictures could also be used for other crafts. You can turn the photos into memories by using them in a scrapbook or collage project.

Whether your child plans on exploring your backyard, or they do so without intending to, it is likely that they will be interested in what they see and learn. Teaching kids science in your own backyard is just one of the many adventures that you and your child can share outdoors. And it just may be the start of a life-long interest in science.
