SciPackDigital resources are stored online in your NSTA Library.
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.
