=Name:= Lucia Moody =Title of Lesson:= Let's Extract some DNA!

Overview:
Let's Extract Some DNA! is the introductory differentiated lesson for Goal 3 of the Biology Curriculum on DNA. This lesson will help students review the cell organelles that learned earlier while using that a to jump into the complex world of how heredity works on a molecular level. Student will start with an activity where they will extract DNA from various fruits. Once the activity is completed, the class will conduct a sharing session with a smart board scribe. Students will then work with partners to draw a flow chart on their Google Docs in order to show what they think happened during the activity. Students will share their products and insights. After wards students will take notes on DNA structure, its history, and how it compares to RNA. Students will watch a video clip on DNA structure, how DNA and RNA was discovered, and how DNA\RNA is important to humans.

Standards:

 * Goal 3: Learner will develop an understanding of the continuity of life and the changes of organisms over time. **
 * Objective 3.01: Analyze the molecular basis of heredity including: DNA structure **
 * Review: Goal 2 Objective 2.02: Investigate and describe the structure and function of cells including cell organelles. **

Essential Question:
How is DNA important to the function of a cell? How is the structure of DNA and RNA similar? different?

Learning Outcomes (What can they do?):
1.Conduct DNA extraction activity on fruit. 2.Produce a flow map or cartoon for more advanced students that describes what is happening in the cell during the DNA extraction 3.Ticket out the Door on Wall Wisher

Duration:
90 minutes

Classroom Logistics:
Rectangular Classroom with board at one end of rectangle Sinks are along one side of rectangle 14 Student Tables Faces the board in groups of three

Tools + Rationale for each tool used:
Strawberries, Kiwi, Bananas, Blender to mix up bananas, Isopropol Alcohol 91%, plastic lunch baggies, Clear dish detergent, plastic forks : to extract the DNA from fruit

Lesson
Step 1. Obtain activity materials for extracting DNA Step 2. Talk with your partner about what happened to the cell in order to extract the DNA. Step 3. Construct a flow map or a cartoon that explains how the DNA was extracted. [|Cartoon Link for DNA extraction]

Step 4. Share cartoons and flow maps Step 5. Go over notes on DNA and RNA structure\history notes Notes on DNA,RNA, History (No Link Yet) [|Understanding DNA video clip]

Step 6:Ticket out the door
