Inquiry Doing Science!
Inquiry: Forming a question • Observation: • An Observation is something you KNOW • Observed using your 5 senses • (what you’ve seen, heard, smelled, tasted, or touched)
Example: • Observations?
Inquiry: Forming a Question Question - After observing things, what do you want to know? Let your curiosity go! • A good scientific question must be: • Testable • Measurable • Include variables • Independent Variable– something you change to see if it affects your results of the experiment in some way • When doing an investigation, you can only change one variable at a time. Why? • Dependent Variable -- The thing that we measure. (being affected by the thing we change).
Inquiry: Forming a Question • Background- What do you know about the question that will help you? • Inference- An inference is something you think you know. You are explaining about how you think something works or why you think something happened.
Example: • What do you know? • Inferences?
Inquiry: Forming a Question • Background- What do you know about the question that will help you? • Inference- An inference is something you think you know. You are explaining about how you think something works or why you think something happened. • Hypothesis - A scientific, testable prediction based on observations. (What do you think is going to happen and why) An inference to your question!
Inquiry: Designing an Experiment • Materials - The things you need to complete the experiment • Procedure - The directions, steps, and drawings for the way to get the answer to your question. • Repeat at least 3x • Why?
Inquiry: Collecting & Presenting Data • Qualitative Observations – describe events during an experiment by sight, touch, smell, taste, or hearing • Quantitative Observations – describes events during an experiment by measuring it (mass, volume, etc…) and has NUMBERS!
Inquiry: Collecting & Presenting Data • Table: A place to write your data • Make it before you do the experiment (why?) • Meaningful title • UNITS! Number of drops on a coin Coin Drops Table Number of Drops of Water on Coins using a Quarter and Dime
Inquiry: Collecting & Presenting Data Graph: Puts data in visual form • Meaningful title • Axis labels • Consistent scale • UNITS! Number of Drops of Water on Coins using a Quarter and Dime # of drops Type of Coin
Inquiry: Analysis and Conclusion • Analysis: How did it go? • Explain and discuss observations • What do the results mean? • Any problems or errors that could have messed up your data? • Limitations: Things that we don’t have but would like to have to do the experiment the best way possible.
Analysis and Conclusion • Conclusion: The answer to your question • Correct Hypothesis? • Yes or No • How do you know? • Use your data and observations to support your conclusion. SUPPORT YOUR ANSWER!! • What does it mean for the world?
