Project
Will the apples overall quality, color, and
odor change under UV florescent lights?
How is this related to irradiation?
• UV rays penetrate the apple’s skin
turning it shades of brown
• Students are able to answer sensory
analysis surveys qualitatively
Tools Used
• Colorimeter
• Calculator
• Graph Paper
• Different medias ( for presentations)
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
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)
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-andwhisker plots
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.
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.
Day 6
• Classroom Presentations
