DNA, Shape and Function

Introduction

The DNA molecule is made up of two strands that coil around each other to form a double helix structure. The DNA double helix structure, which resembles a twisted ladder, is formed by the connections between nitrogenous bases. The rungs of the ladder are formed by the base pairs, and each strand has a backbone made up of alternating sugar (deoxyribose) and a phosphate group. DNA is the genetic instruction for every organism to pass on to their offspring and is needed to develop and survive.

Task
Process

I will divide the class into 4 small groups and assign them each with an area of research:

Research 1 - Franklin

Research 2 - Watson & Crick

Research 3 - Hershey & Chase

Research 4 - Chargaff & Wilkins

 

Each small group will fill out a DNA Discoveries Rubric Chart that I will grade later on. As follows: Scientist Name, Date of Discovery, Experimental Design, Experimental Results, Significance, and Diagram.

The students will be given the opportunity to utilize their school laptops as a resource to access the websites. I will give each small group 3 websites to choose from. This will lead them to several websites for the best researchable material.

Evaluation

The Web Quests will then lead to each small group being given an oral presentation. The lead presenter within each small group will be given a chance to present their research with their own small group before the whole-group presentation for evaluation. I will designate 1 - 3 points on the Rubric Chart based on the correctness of the answer after they hand it in.

Conclusion

For Web Quest, I will have each lead presenter present their research and take questions from the other 3 groups. Each group will take notes on the other group's presentation for discussion the next day.
