Project

• Will the apples overall quality, color, and odor
  change under UV florescent lights?
• How is this related to irradiation?
• UV rays penetrate the apples skin turning it
  shades of brown
• Students are able to answer sensory analysis
  surveys qualitatively

9
Tools Used

• Colorimeter
• Calculator
• Graph Paper
• Different medias ( for presentations)

10
Day 1

• Warm-up
• Show students the radiation and irradiation signs
• Activity 1
• Have the class prepare their apples
• Activity 2
• Teach students how to use the colorimeter
• Activity 3
• teach students how they are going to use the
  sensory analysis surveys to judge the apples

11
Day 2

• Warm up
• Read an article on irradiation and discuss its
  importance
• http//www.food-irradiation.com/artpub.htm
• Activity 1
• Collect data
• Sensory analysis survey
• Colorimeter
• Activity 2
• Provide information from the chicken irradiation
  sensory analysis testing do to statistical
  analysis (mean, median, mode, range)

12
Day 3

• Warm up
• Review with students and discuss the importance
  of statistical analysis
• Activity 1
• Collect data
• Sensory analysis survey
• Colorimeter
• Activity 2
• Using the same information from the chicken
  irradiation and much of the information from Day
  2 the students are to make box-and-whisker plots

13
Day 4

• Warm up
• Draw a box and whiskers plot and label its five
  parts.
• Activity 1
• Collect data
• Sensory analysis survey
• Colorimeter
• Activity 2
• Groups will create a scatter plot of their
  colorimeter readings.

14
Day 5

• Warm up
• Students will be given a graph of a scatter plot.
  They will then draw conclusions about this
  graph.
• Activity 1
• Collect data
• Sensory analysis survey
• Colorimeter
• Activity 2
• Students will be given data to make a bar graph.
• Students will start group project.
