Presentation Transcript

  1. Scientific Thinking

  2. HYPOTHESIS-BASED SCIENCE • Mostly about explaining nature • Hypothesis • Tentative answer to well-framed question • Must be testable to see if true Use the Scientific Method

  3. Question • Your grandmother tells you not to stand by the microwave because it is dangerous. You are getting ready to make popcorn and wonder if the microwave is dangerous to corn. You wonder if corn that has been microwaved will be able to grow. You decide to set up an experiment. • What is your hypothesis?

  4. Experimental Design • Set up the experiment in a way to test the hypothesis • Groups: 1. Experimental Group(s): have factor you are testing 2. Control Group: does not have factor you are testing • Only thing different between the experiment group(s) and control group is factor (independent variable)you are testing *

  5. Variables: factors in the experiment • 1. Independent: factor you change (“I Change”) • 2. Dependent: factor you measure or observe (“Data collect”) • 3. Control: factors held constant

  6. Example: Does Microwaving corn impact its ability to grow? • Experimental Design: • Hypothesis • Variables • Groups

  7. Example: Does the amount of calories eaten affect the activity levels of dogs? • Experimental Design: • Variables: • Groups:

  8. Graphing • TALKS • Title (Make meaningful) • Axis (X & Y) • Label (units) • Key (as needed) • Scale (determine for x & y axes) • Scale • Range • # Squares • Range/ # Squares • Easy counting #s (greater than or lest than quotient from above) • DRY MIX • (Dependent, Responding on Y-axis) • (Manipulated, independent on X-axis)

  9. Best Fit Line

  10. Data Analysis
