Just What Is Science Anyway??? ……a journey through the scientific method...

Science is: a process of inquiry - asking questions and getting answers you do science There are many sciences: life science poli-science social science etc

The Scientific Method A very good way to do science Easy to follow Repeatable Thorough Can be applied to any problem. Reports written factually Do not use pronouns: you, me, we, she, he, they, my, I, his, her, their etc.

Step 1: Problem or Purpose The problem is what you are trying to solve Always state the problem in the form of a question. Use how, why, what words. Example: What design is best for protecting a raw egg when dropped from a two story building?

Step: 2 Hypothesis The best solution based on your research An educated statement of what will happen Always written in a complete sentence

Step 3: Materials Use specific amounts List all material items needed for the experiment Use bullets or numbers

Step 4: Procedure Provide detailed steps to follow in conducting the experiment. List each step Start each step with a verb Example: Slice two pieces of bread or pour 10ml into a beaker It must be so detailed so that anyone who may dispute your work can reproduce exactly what you did.

Step 5: Observations (Results & Data) Quantitative data- observations you measure Include data tables and graphs when appropriate: Qualitative data: Record data gained using 5 senses (sight, touch, smell, hearing, taste)

Step 6: Conclusion Use complete sentences to explain if the experiment solved the problem Discuss whether your original hypothesis was correct or incorrect Avoid yes or no statements

Step 7: Analysis - this step is very important Step 7: Analysis - this step is very important! Do not restate the results here State what the data means What was learned from this lab? Discuss any variables that may have affected the results What, if any, further investigation may need to be conducted on this problem? 5. Independent Variables (IV) - the part of the experiment that you change 6. Dependent Variables (DV) - the part of the experiment that changes as a result of the manipulation 7. Constants - the parts of your experiment that does not change
