Skittles: Taste the Rainbow Lab Writing the Perfect Lab Report
Skittles: Taste the Rainbow Research Problem: Does the flavor of a Skittle reflect the outer color?
What do we need to know? 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?

The Rainbow Colors and Flavors Google the colors and flavors of Original Skittles Orange = Orange Yellow = Lemon Green = Green Apple Red = Strawberry Purple = Grape
Experiment Ideas Think of a minimum of 3 experiment ideas Remember, our research question is: Does the flavor of a Skittle reflect the outer color?
Skittles: Taste the Rainbow 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 color right Control variables: Same skittles, all blind-folded, same # of skittles, rinse water after each taste Control Group Manufacturers suggestion of flavor Repeated Trials: X10
Hypothesis If _________________, then______________, (manipulated var.) (responding var.) because___________. Make sure it 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. (Smart Board directions)
Data You & Partner are responsible for 10 trials We will be combining the class data What is your manipulated variable? What is your responding variable?
Graphing You will graph the class data. Make sure your graph includes: Title Labeled X and Y axis And is spread out Bar chart Key/Legend
Conclusion Look at your blue checklist: ____Did you restate your hypothesis? ____Did you state if you hypothesis was “supported” or “not supported”? ____Did you include your data to back up your claim? Reflection (#4) ____Did you report any problems or errors you had AND suggest improvements for future experiments?
