                                                                                   Growth and Development
                                                                                                Grades 6-9


                                     Program Objectives
Program Description: 
Through an indepth discussion of scientific concepts, students learn how genetic concepts explain 
human characteristics and health conditions delivered at fertilization.   
 
Standards: 
PA Standards 3.3.7ac, 3.3.10ac; 10.1.9e 
NJ Standards 2.1.8b, 3.4.6a 
 
Objectives: 
Upon completion of the program, students will: 
       1. identify DNA as the chemical of heredity 
       2. recognize the twisted double helix model as DNA 
       3. list three genetically inherited traits 
       4. list three factors that can mutate genes 
 
Terms: 
 
Bases small molecules that help make up the DNA molecule (adenine, guanine, thymine, cytosine) 
 
Chromosomes Long sections of DNA that are coiled up inside the nucleus of a cell.  23 chromosomes 
are donated from both mom and dad to give us the 46 chromosomes needed to make a human being 
 
Deoxyribonucleic Acid (DNA) The chemical found in cells that determines inherited traits 
 
Dominant Trait a physical characteristic that has a higher likelihood of showing up in a human being 
 
Double Helix The shape of the DNA molecule; a "twisted ladder" 
 
Genes a section of DNA on a chromosome that codes for a specific trait 
 
Genetics The study of the passing of characteristics from parent to child  
 
MutationsUnexpected changes in the DNA 
 
Recessive Trait a physical characteristic that has a smaller chance of being seen in a human being 
 
Traits Physical characteristics that show up as a result of genetic sequence

                           Reading Comprehension Worksheet
Objective: 
To utilize reading comprehension skills to identify inherited characteristics and recognize influences 
that may cause genetic mutations. 
 
Directions: 
    1. Read the short story below. 
    2. Use the information in the story to answer the discussion questions. 
    3. Discuss answers as a class. 
 
Discussion Questions: 
    1. Identify 4 genetic physical traits that are explained in the story about Maggie Marlow. 
 
    2. What factor(s) in the story may put Maggie at risk for developing a genetic mutation? 
          
    3. Should Maggie be concerned about any inherited diseases?  Why?  (this may require a little 
         additional research) 
          
    4. List 2 of Maggie's characteristics that are not inherited traits. 
          
                                         Maggie Marlow
        It was a bright, crisp, fall day and Maggie Marlow was on her way home from school.  She was 
lumbering down the street as she tried to manage the awkward case she held in her left hand.  Over 
her left shoulder, she slung her backpack.  It was heavy under the weight of her Advanced Algebra and 
Advanced Biology book. Maggie had long brown hair that was pulled up in a pony tail and she was 
much shorter than she would have liked, a very proud four foot eleven and a half inches.   
 
        Up ahead, Maggie saw her best friend Herbert, who was standing over a pile of books and 
papers, looking very distraught.   
         
        "What's up?" yelled Maggie as she rushed over to Herbert. 
         
        "Oh, nothing...My backpack just ripped and now my stuff is all over the ground.  Where are you 
going?" asked Herbert. 
         
        "I'm going home.  Today was the last rehearsal before the show Friday night and I wanted to 
take my guitar home and restring it.  Why? Do you need help?"  
         
        Herbert started to get a little annoyed. 
         
        "No, I guess I'll just stand here all afternoon and wait for some nice person to come along and 
help me.  I thought it would be you, but I guess I was wrong." He huffed.

                                                                                         Growth and Development
                                                                                                      Grades 6-9


           
          "Okay, okay..." Maggie agreed.  "I'll help you... Jeeze!  Do you see I'm carrying this guitar and a 
backpack of my own?  Plus, I have to get home to see my mom before she goes to the hospital for 
more xrays tonight.  I usually go with her to hold her hand, but tonight I need to watch my little sister.  
So, it is the last chance I will have to see her before she checks into the hospital tomorrow morning. " 
           
          "Is she still sick?" asked Herbert. "I thought she was doing better." 
           
          "Diabetes doesn't go away, Herbert.  You have it forever," said Maggie knowingly. 
           
          "I thought there was something wrong with her foot," said Herbert quite confused, "what does 
that have to do with diabetes?" 
           
          "The sore on her foot was a result of the diabetes," explained Maggie.  She is going in to get her 
foot fixed, but when the surgery is done, she will still have diabetes." 
           
          "Oh, sorry..." huffed Herbert.  "What do I know?  Hey, are you going to help me or not?" 
           
          "Okay, okay..." she said as she gathered up all of Herbert's papers.  Maggie steadied herself 
under the weight of all she had to carry and she and Herbert were on their way.   
           
          She really did like Herbert.  When they were younger, he used to count the freckles on her face 
(he always stopped once he reached one hundred).  She loved that.
