1 Skittles: Taste the Rainbow Lab Writing the Perfect Lab Report

2 Research Problem: Does the flavor of a Skittle reflect the outer color? Skittles: Taste the Rainbow

3 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? What do we need to know?

4 Example: What not to do: &playnext=1&list=PLE88667B361DA7076 &playnext=1&list=PLE88667B361DA7076 Real Life Example:

5 Orange = Orange Orange = Orange Yellow = Lemon Yellow = Lemon Green = Green Apple Green = Green Apple Red = Strawberry Red = Strawberry Purple = Grape Purple = Grape The Rainbow Colors and Flavors Google the colors and flavors of Original Skittles

6 Think of a minimum of 3 experiment ideas Remember, our research question is: Does the flavor of a Skittle reflect the outer color? Experiment Ideas

7 Chose one and SUMMARIZE Don’t write anything down yet. Let’s discuss and agree on a procedure. We will be combining class data Skittles: Taste the Rainbow

8 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 Variables

9 If _________________, then______________, (manipulated var.) (responding var.) because___________. Make sure it answers the research question: Does the flavor of a Skittle reflect the outer color? Hypothesis

10 Think back to the ice-cream sundae procedure: THAT’S the level of detail we need. (Smart Board directions) Procedure

11 You & Partner are responsible for 10 trials We will be combining the class data What is your manipulated variable? What is your responding variable? Data

12 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 Graphing

13 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? Conclusion
