Overview of Lesson Day 1 –Activity 1: Preparation of Apples –Activity 2: Learn to use Colorimeter –Activity 3: Understand Measurement Techniques Day 2 –Activity 1: Gather Apple Information –Activity 2: Statistical Analysis
Overview continued… Day 3 –Activity 1: Gather Apples Information –Activity 2: Graphical Representations (box and whisker plots) Day 4 –Activity 1: Gather Apples Information –Activity 2: Graphical Analysis (scattered plots)
Overview continued… Day 5 –Activity 1: Gather Apples Information –Activity 2: Put Information Together & Draw Conclusions Day 6 –Classroom Presentations
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-and- whisker 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.
