  3. Mathematics 8th grade Algebra I Algebra II Pre-Calculus Mathematical Models with Applications Science Biology Chemistry Physics TEKS Involved

  4. NCTM Standards Number and Operations Algebra Geometry Measurement Data Analysis & Probability Problem Solving Communication Connections Representations

  5. 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

  6. 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)

  7. Overview continued… • Day 5 • Activity 1: Gather Apples Information • Activity 2: Put Information Together & Draw Conclusions • Day 6 • Classroom Presentations

  8. 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

  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.

  15. Day 6 • Classroom Presentations
