1 Skittles: Taste the Rainbow Lab Writing the Perfect Lab Report
2 Skittles: Taste the Rainbow Research Problem: Does the flavor of a Skittle reflect the outer color?
3 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?
4 Example: http://www.youtube.com/watch?v=TunJoQmeisA What not to do:Real Life Example:
5 The Rainbow Colors and Flavors Google the colors and flavors of Original SkittlesOrange = OrangeYellow = LemonGreen = Green AppleRed = StrawberryPurple = Grape
6 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?
7 Skittles: Taste the Rainbow Chose one and SUMMARIZEDon’t write anything down yet. Let’s discuss and agree on a procedure.We will be combining class data
8 Variables Manipulated variable: The color of the skittle Responding variable:If the person gets the color rightControl variables:Same skittles, all blind-folded, same # of skittles, rinse water after each tasteControl GroupManufacturers suggestion of flavorRepeated Trials:X10
9 HypothesisIf _________________, then______________, (manipulated var.) (responding var.) because___________.Make sure it answers the research question:Does the flavor of a Skittle reflect the outer color?
10 ProcedureThink back to the ice-cream sundae procedure: THAT’S the level of detail we need.(Smart Board directions)
11 Data You & Partner are responsible for 10 trials We will be combining the class dataWhat is your manipulated variable?What is your responding variable?
12 Graphing You will graph the class data. Make sure your graph includes: TitleLabeled X and Y axisAnd is spread outBar chartKey/Legend
13 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?
