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

Page 9: E 3  Lesson Plans

Tools Used

• Colorimeter

• Calculator

• Graph Paper

• Different medias ( for presentations)

Page 10: E 3  Lesson Plans

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

Page 11: E 3  Lesson Plans

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)

Page 12: E 3  Lesson Plans

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

Page 13: E 3  Lesson Plans

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.

Page 14: E 3  Lesson Plans

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.
