~2-3 days

Big Idea 1:  The Groundwork

 

Essential Questions:

  • What is Biotechnology?
  • What are the fields in which Biotech is used? 
  • What are the practical applications of Biotech?

In these lessons, students will get a general overview of what biotechnology is, the history and advances of biotechnology, and the various fields in which biotech is being used to help find solutions to global problems.

 

 

 

Lesson 1-1: Intro to Biotechnology

 

 

 

Lesson 1-2: Biotech Jigsaw

 

Lesson 1-3: Genetics and Society

 
  • What is one thing you learned from each of the Biotech Jigsaw presentations?

 

  • Based on your Web Quest, what are the 5 practical applications that Genetics and Biotechnology are having on Society.

 

  • How has your learning during these past lessons affected how you think of Biotechnology?

 

~3-4 days 

Big Idea 2: The History

 

Essential Questions:

  • How Do Scientists Use Biotechnology to Help Conserve Species?
  • What is our scenario? 
  • Who Are The Scientists?  
  • Why Elephants?
  • What is the Ivory Story? 
In these lessons, students will have an elicitation of how biotechnology is used to solve real world ecological problems (example in Montana). They will then get local by reading about Washington scientists Comstock & Wasser and become familiar with their elephant research. This will prime the opening of the "Who Dung It" project scenario in which they simulate reaching out to Dr. Comstock.  Follow-up lessons 2-3 and 2-4 fill in important background knowledge about the laws and ethics surrounding the ivory trade. Lesson 2-1: Using Biotechnology to Conserve Species

Lesson 2-2:  Using Biotech to Conserve Species: "WHO DUNG IT? Scenario"

 

Lesson 2-3: Elephant Laws & Ethics Web Quest

 

Lesson 2-4: Ethical Dilemmas: Stake Holder Case Studies

  • How do Dr.'s Comstock and Wasser use biotechnology to help conserve species?
  • Should we be working internationally to conserve a species?
  • How can Biotechnology be used to conserve a species?
  • What is your stake in the issue of ivory? What can you do? 
~2-3 days 

Big Idea 3: The Mission

 

Essential Questions: 

  • What techniques do we need to perform our mission? 
  • Can we use DNA Technology to track the ivory?
In these lessons, students will further their experience with the techniques of micro-pipetting, sample preparation and electro-phoresis. They will learn how the physical properties of DNA molecules allow their separation by agarose gel electrophoresis and apply this technique to an their confiscated-ivory scenario. Final analysis and discussion will help students to understand the relevance of these technique to scientific research and global issues.
Lesson 3-1: Mission Techniques! 

Lesson 3-2 Option 1: Analyzing the Ivory DNA (WET LAB)

 

Lesson 3-2 Option 2: Analyzing the Ivory DNA (PAPER LAB)

 

Lesson 3-3: Laboratory Data Analysis

  • What are polymorphisms and how do they contribute to the varying fragment lengths of DNA when it is cut?
  • What attribute of DNA causes it to move through the gel? 
  • What evidence from your laboratory  contributed to your conclusion of where the confiscated ivory originated from?
~1-2 days 

Big Idea 4: The Assessment

 

Essential Questions:

  • Can we use what we've learned and apply to the conservation of another species? 

In this summative assessment, students are once again presented with a scenario; in this case, a scientist has the task of determining if Japanese marketed whale meat is from endangered whales or not.   Students read the scenario and use their prior knowledge from the project to answer the questions provided.

Lesson 4-1: Japanese Whaling Mini-Documentary  Lesson 4-2: Whale Meat Assessment 
  • Design your own experiment (using DNA technology) related to this scenario that you could perform in order to identify the marketed whale meat.
