Scientific Method

10/30/2015Template copyright 2005 www.brainybetty.com2 Scientific method is a series of steps that scientists use to answer questions and solve problems. The goal of the scientific method is to come up with reliable answers and solutions.

10/30/2015Template copyright 2005 www.brainybetty.com3 Even before starting the investigation, a scientist will make observations. Observation is any use of senses to gather information. Observations are made throughout the scientific investigation. There are two types of observations: Qualitative and Quantitative.

10/30/2015Template copyright 2005 www.brainybetty.com4 Qualitative observations are our perceptions of objects or natural events using our senses.  Example: Pink is a better color than green. Quantitative observations may also include approximations and comparisons.  Examples: The tree is taller than that one.  Example: The tree is 15ft tall.

10/30/2015Template copyright 2005 www.brainybetty.com7 Scientific Method Steps: 1. Ask a Question The question is stated in a clear and concise manner.

10/30/2015Template copyright 2005 www.brainybetty.com8 2. Form a Hypothesis A hypothesis = an educated guess to the question This answer must be testable but it may not be the correct answer after being tested.

10/30/2015Template copyright 2005 www.brainybetty.com9 3. Test the Hypothesis Once a hypothesis is established it must be tested. The hypothesis is tested by gathering data that can determine whether the hypothesis is supported or not. Procedures are step-by- step directions during the experiment

10/30/2015Template copyright 2005 www.brainybetty.com11 5. Draw Conclusion The conclusion is drawn by looking at the results and comparing them with the question. It must include whether or not the hypothesis was supported based on the results.
