2. Tennessee SPI Objective: Analyze data on levels of variation within a population to make predictions about survival under particular environmental conditions. Notes Science Essential Learning Students will predict which sub-group(s) in a population are best suited to survive under specific environmental conditions. Essential Question What is the connection between variation within a population and the sub-group(s) survival rate? SPI 0807.5.3 Variation in Populations

3. Notes Science 1) Variation refers to a variety or diversity of traits (different kinds) within any given population of organisms. Example: Look around at the other students. Notice the unique traits that individuals have such as hair color, height, eye color, skin color, etc. 2) Likewise variations occur in nature in populations of plants, animals, insects, fish, etc. Variation in Populations This is an example of variation within the student population SPI 0807.5.3 Variation in Populations
