Skittles Lab Question Does the flavor of a
Skittle’s Lab
Question • Does the flavor of a Skittle reflect the outer color?
Research • What is a “blind” taste test? • What is a “double blind” taste test? • What colors are there in original Skittles? What are the flavors of the colors?
Explore Ideas • Think of a minimum of 3 experiment ideas • Remember, our research question is: Does the flavor of a Skittle reflect the outer color?
Plan Summary • Chose one and SUMMARIZE • Don’t write anything down yet. Let’s discuss and agree on a procedure. • We will be combining class data
Variables • Manipulated variable: – The color of the Skittle • Responding variable: – If the person gets the flavor right • Control variables: – Same Skittles, all blind-folded, same # of Skittles, rinse water after each taste • Control Group �Information on the bag of Skittles • Repeated Trials: – X 10 (5 x each taster)
Hypothesis If _ (manipulated var. ) , then_(responding var. ), because______. • Make sure hypothesis answers the research question: – Does the flavor of a Skittle reflect the outer color?
Procedure • Think back to the ice-cream sundae procedure: THAT’S the level of detail we need.
Data • You & Partner are responsible for 10 trials • We will be combining the class data Color Guess Correct/Incorrect
Analysis • Find the percent correct for each color from the class data Color Red Orange Yellow Green Purple Total Tested Number Correct Percent Correct
Graph • You will graph the class data. • Make sure your graph includes: – Title – Labeled X and Y axis – And is spread out – Graph uses the entire paper – Bar chart. Colors are least to greatest correct – Key/Legend
Conclusion Use this checklist: ____Did you state if you hypothesis was “supported” or “not supported”? ____Did you restate your hypothesis? ____Did you include your data to back up your claim? Reflection (#4) ____If I did this experiment again I would. . . Be sure to include what you would change and the scientific reason for your change.
