Description

SciPacks are self-directed online learning experiences for teachers to enhance their understanding of a particular scientific concept and its related pedagogical implications for student learning. Unlimited expert content help via email and a final assessment both facilitate and document teacher learning.

The Heredity and Variation SciPack explores patterns of inheritance and discusses how offspring can look similar to their parents yet still possess differences within their genetic code. These differences can sometimes affect (positively or negatively) an offspring’s ability to survive and reproduce. Our ancestors used their observations of plants and animals to cultivate crops and domesticate animals. Now, through the use of technology and our current understanding of the DNA molecule, scientists can study individual genes and a gene’s impact on the inheritance of traits.

Ideas For Use

SciPacks are discrete learning experiences teachers can use to enhance their understanding of a particular scientific concept. Each SciPack contains a collection of three to five free Science Objects, which provide an understanding of the science content that supports curricula requirements by providing a structured set of learning experiences through simulations and practice assessments. Science Objects challenge teachers to explore and explain real world phenomena. Science Objects are founded on the principle that learners must be challenged with a problem, observation, data, etc., in order to develop scientific understanding. Science Objects present problems, phenomena, demonstrations, and simulations utilizing inquiry-based learning.

In addition to comprehensive inquiry-based learning materials tied to Science Education Standards and Benchmarks, the SciPack includes the following additional components:
  • Pedagogical Implications section addressing common misconceptions, teaching resources and strand maps linking grade band appropriate content to standards.
  • Access to one-on-one support via e-mail to content “Wizards”.
  • Final Assessment which can be used to certify mastery of the concepts.
Learning Outcomes:

Heredity and Variation: Inheritance
  • Explain how domestication of plants and animals produced an early understanding of inheritance.
  • Use Mendel’s model to explain patterns of inheritance represented in graphic form (for example, data tables, histograms, etc.).
  • Identify the conditions required for an inheritance pattern to be explained correctly by Mendel’s model.
  • Use data representing patterns of inheritance to support the idea that some observable traits are defined by discrete units of inheritance that segregate and assort independently of one another during inheritance.
Heredity and Variation: Genes in Action
  • Distinguish among the following structures by describing their relationship to one another: DNA, chromosomes, genes, and alleles.
  • Describe the role genes play in the production of proteins and defining the phenotype of an organism.
  • Compare and contrast the DNA in cells produced during asexual reproduction versus the DNA in gametes produced during meiosis.
  • Indentify and describe those steps within the process of meiosis that explain the random distribution of genotypes among offspring resulting from sexual reproduction.
  • Explain how the recombination of the allele pairs for individual genes during sexual reproduction results in phenotypic variation among offspring.
Heredity and Variation: Mutation Provides Variation
  • Compare and contrast genetic mutations with genetic variations resulting from the process of meiosis.
  • Identify and describe the general processes involved in the creation of genetic mutations.
  • Describe possible consequences of genetic mutations.
  • Describe conditions necessary for genetic mutations to be inherited by an organism’s offspring.

  • Life Science
    • Life cycles of organisms
      • Plants and animals closely resemble their parents. (K-4)
      • Many characteristics of an organism are inherited from the parents of the organism, but other characteristics result from an individual's interactions with the environment. Inherited characteristics include the color of flowers and the number of limbs of an animal. (K-4)
      • Other features, such as the ability to ride a bicycle, are learned through interactions with the environment and cannot be passed on to the next generation. (K-4)
    • Structure and function in living systems
      • Cells carry on the many functions needed to sustain life. They grow and divide, thereby producing more cells. (5-8)
    • Reproduction and heredity
      • Reproduction is a characteristic of all living systems; because no individual organism lives forever, reproduction is essential to the continuation of every species. (5-8)
      • Some organisms reproduce asexually (5-8)
      • Some organisms reproduce sexually. (5-8)
      • In many species, including humans, females produce eggs and males produce sperm. (5-8)
      • Plants also reproduce sexually--the egg and sperm are produced in the flowers of flowering plants. (5-8)
      • An egg and sperm unite to begin development of a new individual. That new individual receives genetic information from its mother (via the egg) and its father (via the sperm). (5-8)
      • Sexually produced offspring never are identical to either of their parents. (5-8)
      • Every organism requires a set of instructions for specifying its traits (5-8)
      • Heredity is the passage of these instructions from one generation to another. (5-8)
      • A human cell contains many thousands of different genes. (5-8)
      • Each gene carries a single unit of information. (5-8)
      • An inherited trait of an individual can be determined by one or by many genes, and a single gene can influence more than one trait. (5-8)
      • Hereditary information is contained in genes, located in the chromosomes of each cell. (5-8)
      • The characteristics of an organism can be described in terms of a combination of traits. (5-8)
      • Some traits are inherited and others result from interactions with the environment. (5-8)
    • The cell
      • Cells store and use information to guide their functions. (9-12)
      • The genetic information stored in DNA is used to direct the synthesis of the thousands of proteins that each cell requires. (9-12)
    • Molecular basis of heredity
      • In all organisms, the instructions for specifying the characteristics of the organism are carried in DNA, a large polymer formed from subunits of four kinds (A, G, C, and T). (9-12)
      • The chemical and structural properties of DNA explain how the genetic information that underlies heredity is both encoded in genes (as a string of molecular "letters") and replicated (by a templating mechanism). (9-12)
      • Each DNA molecule in a cell forms a single chromosome. (9-12)
      • Most of the cells in a human contain two copies of each of 22 different chromosomes. (9-12)
      • In human cells, there is a pair of chromosomes that determines sex: a female contains two X chromosomes and a male contains one X and one Y chromosome. (9-12)
      • Transmission of genetic information to offspring occurs through egg and sperm cells that contain only one representative from each chromosome pair. An egg and a sperm unite to form a new individual. (9-12)
      • The fact that the human body is formed from cells that contain two copies of each chromosome--and therefore two copies of each gene--explains many features of human heredity, such as how variations that are hidden in one generation can be expressed in the next. (9-12)
      • Changes in DNA (mutations) occur spontaneously at low rates. (9-12)
      • Some of the changes in DNA make no difference to the organism, whereas others can change cells and organisms. (9-12)
      • Only mutations in germ cells can create the variation that changes an organism's offspring. (9-12)
  • History and Nature of Science
    • Science as a human endeavor
      • Science and technology have been practiced by people for a long time.
      • Men and women have made a variety of contributions throughout the history of science and technology.
      • Doing science or engineering can be as simple as an individual conducting field studies or as complex as hundreds of people working on a major scientific question or technological problem. (9-12)
    • Nature of science
      • Scientists formulate and test their explanations of nature using observation, experiments, and theoretical and mathematical models. Those ideas are not likely to change greatly in the future. (5-8)

Spelling?
  James Johnson (Custer City, PA) on December 8, 2012
  In the Graphic Representations lesson, the following line occurs: "Horizontal lines connecting males and females represent mating and verticle lines show offspring that result from the mating." I think verticle should be "vertical."

Heredity and Variation
  James Johnson (Custer City, PA) on December 11, 2012
  I ran part of this SciPack to my students via Promethean Board and I was really amazed at how interested they were at the different activities and the interactive activities. Some of the kids I was having the hardest time reaching were the most interested! One kid who chronically sleeps through part of the class scooted up to the front and had numerous questions. Homerun!

Heredity and Variation
  James Johnson (Custer City, PA) on December 9, 2012
  Great Scipack. I learned a lot and the assessment questions were accurate and fairly matched to the subject matter. Really enjoyed the activity and learned some new stuff I had forgotten. I will use this in my class for sure!

Repetition is Key
  Andrea Gouldy (Granbury, TX) on October 21, 2012
  I found this SciPack to be very repetitive but still engaging. Each time the same topic was brought up it was introduced in a different way which helped me to grasp the information more quickly and really understand deeper what it was I was trying to learn.

Basic Overview
  Roselle on March 8, 2013
  This was a great basic overview of heredity and variation. I feel it was geared more towards a middle school level. I would recommend that you seek additional support material if you are teaching high school genetics for the first time.

Good Very Basic Review
  Rebecca F (Elizabeth, WV) on December 6, 2012
  The Heredity and Variation SciPack covers the major topics that would be covered in a typical genetics unit in high school biology, though not in great depth. It serves as a nice refresher, but if you want to dig deeper you'll be disappointed.
