  1. Angela Medley’s Science Lesson ITEC 7430 Internet Tools

  2. Science standards • Students will analyze how biological traits are passed on to successive generations. • b. Explain the role of DNA in storing and transmitting cellular information. • f. Examine the use of DNA technology in forensics, medicine, and agriculture. • Students will recognize that offspring can resemble parents in inherited traits and learned behaviors. • a. Explain the role of genes and chromosomes in the process of inheriting a specific trait. • b. Discuss what a gene is and the role genes play in the transfer of traits.

  3. NETS Standards • 1. Creativity and Innovation • 2. Communication and Collaboration • 3. Research and Information Fluency • 4. Critical Thinking, Problem Solving, and Decision Making • 5. Digital Citizenship • 6. Technology Operations and Concepts

  4. Overview of Lesson • How do people experience taste? Some people savor the flavor of beets while others grimace in disgust. What accounts for the difference? In this lesson, students will investigate the genetic basis of taste by testing their ability to taste a bitter compound (PTC) and by sampling food. The instructional objective for this project is for the students to gain knowledge about genetic heredity. After completion of this lesson, the students should understand the use of the Punnett square and be able to determine if a child will receive a trait based upon parental genetic traits.

  5. Essential Questions • What is the definition of a taste receptor? • Explain how genes can influence our taste perception. • Describe how parental traits can be passed on to offspring.

  6. Instructional strategies • The research-based instructional strategies I will use with this lesson will include but will not be limited to: • Checks for understanding along with efforts and recognition for achievement • Informal teacher observations with feedback • Cooperative Learning: Students working together in small groups • Cues and Questions : Using hints and questions to activate prior knowledge and deepen student understanding • Graphic organizers: Providing a visual display of something being discussed or considered • Complex cognitive tasks such as investigation, problem solving, decision making and experimental inquiry

  7. Assistive technologies • Word processor will be helpful for those students with physical issues • Note sheets and blank tables would be useful for visually impaired students as these can be enlarged. • Auditory disabilities will best be addressed through the use of a headset and an individual computer for viewing the videos.

  8. Assessment • Students will produce a spreadsheet with data from the lab. They will also create a bar graph detailing their findings. The bar graph will be graded by the teacher in order to assess the ability to construct an effective bar graph from the lab data. The students will complete a wiki, blog, website, or prezi that discusses the following: • What is the purpose of this lab? • What knowledge have I learned? • What is my hypothesis for experiment? • Describe the steps of the experiment. • Show your data • Write your conclusion
