Scientific Definitions

The YourDictionary Web site defines science as the “systematized knowledge derived from observation, study, and experimentation carried on in order to determine the nature or principles of what is being studied.” This includes the departments of learning and bodies of fact in disciplines such as anthropology, archaeology, astronomy, biology, botany, chemistry, cybernetics, geography, geology, mathematics, medicine, physics, physiology, psychology, social science, sociology, and zoology.

Scientists generally add to their knowledge by conducting research using the scientific method. The scientific method is a process that applies logic, order, and critical thinking skills to solving problems and finding new information.

The steps to the scientific method are as follows:

1. Ask a question to define the problem or issue you wish to resolve.
2. Do background research to learn what others have discovered about your topic.
3. Construct a hypothesis to determine how you think your questions should be answered.
4. Test your hypothesis by conducting an experiment.
5. Analyze the data you have collected during the experiment.
6. Formulate a conclusion based on your research and the data you’ve gathered from your experiment.
7. Communicate your results to others who have an interest in the topic.

One of the most interesting points to remember about the scientific method is that it can’t absolutely verify that something is true. The scientific method can only prove that a particular hypothesis is false. In regards to the scientific method, Albert Einstein once said, “No amount of experimentation can ever prove me right; a single experiment can prove me wrong.”

Science Definitions for Kids

Children are naturally interested in science because it’s a way to develop their understanding of how the world works. As a parent, you can encourage your child’s interest in science by providing links to Web sites that offer definitions and other resources relating to topics such as biology, anatomy, astronomy, or chemistry. For example:

• Enchanted Learning offers a great way to introduce students in grades K-3 to essential scientific concepts. Some of the many helpful resources on this site include a printable illustrated botany dictionary, animal information sheets to color, and activities to teach about the function of the rainforest.
• Edu Place has a printable glossary that provides basic science definitions appropriate for upper elementary school children. Some of the many terms covered include acid rain, astronomy, gravity, metamorphosis, and water cycles.
• Fact Monster is a nicely designed educational Web site for children that features a number of science-related resources. You’ll find definitions, experiments, articles, trivia, and more on topics ranging from health and body to astronomy and space.
• Yahoo! Kids has created an information portal page that children can use when completing their science homework. If your child can’t find the answers he/she needs, there is also an “Ask Earl” feature that allows for question submissions relating to a variety of topics.

Science Definitions for Teens and Adults

Teenagers and adults seeking to increase their understanding of science-related topics may do best to begin their search by visiting Access Science, a resource from McGraw-Hill. This innovative online dictionary and encyclopedia provides a wealth of scientific information. Simply type the term you wish to learn more about into the search box at the top of the page.
