Teacher Name:
 Kevin Beckner
Grade:
 Grade 9-10
Subject:
 Science

Topic:
 Structure of DNA
Content:
 The basic structure of DNA, learning key terms: Double Helix Deoxyribose Nitrogenous Base Adenine,Thymine Guanine,Cytosine
Goals:
 Strand II: The Content of Science Standard II (Life Science): Understand the properties, structures, and processes of living things and the interdependence of living things and their environments.9-12 Benchmark II: Understand the genetic basis for inheritance and the basic concepts of biological evolution.
Objectives:
 Students will know the basic structure of a DNA molecule and be able to apply them to building a model
Materials:
 Toothpicks (2 colors) Mini Marsh mellows (4 colors) Licorice
Introduction:
 Teacher will give a short history of DNA. Then will diagram the molecule on the board for the students for students.
Development:
 Teacher will describe and draw the molecule for the students and present a completed model of DNA using candy.
Practice:
 The students will gather their materials in accordance to what they need.
Accommodations:
 I will provide any accommodations for any exceptionality via IEP
Checking For Understanding:
 Each student will show me their model and answer a series of oral questions before they are allowed to eat their model.
Closure:
 We will review the terms on the board by each student answering one "exit" question. Specifically one they weren't able to answer before for the model consumption.
Evaluation:
 Pictures of their models will be taken and used for a semester-long portfolio.
Teacher Reflections:
 To be completed after lesson.
