This NGSS-aligned, interactive lecture provides an outline for: evolution for natural selection, distribution of traits, gene pools, selection pressures, types of selection, evidence for evolution and artificial selection. It is intended for introducing topics and student note-taking between more in-depth activities.
Real life examples are provided and slides come with teacher notes. I understand each teacher covers topics a little differently, so feel free to edit and differentiate for your classroom and students' needs. Make sure to preview it in "present" mode to view all the animations. Enjoy!
NGSS HS-LS4-2 Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
NGSS HS-LS4-4 Construct an explanation based on evidence for how natural selection leads to adaptation of populations.
NGSS HS-LS4-3 Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.
NGSS HS-LS4-1 Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.
