This unit is packed with engaging activities intended to address the NGSS MS standards:
NGSS MS-LS3-1 Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.
NGSS MS LS3-2 Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.
This resource includes two informative slideshows, nonfiction text passages, interactive notebook flaps, lesson plans, labs, task cards, a game on mutation, response sheets and a multiple choice assessment. Answer keys are included!
Students will use Punnett Squares to determine the possible percentages of genotype and phenotype of offspring. They will learn about dominant and recessive alleles as well as about co-dominance and incomplete dominance. Students will make a model to show their understanding of three types of mutations: deletion, insertion and substitution. Students will learn that Students will learn about asexual reproduction and will compare advantages and disadvantages of asexual reproduction verses sexual reproduction. And finally students will learn about natural selection and how some mutations give a species an advantage which may be passed onto offspring. Note: This resource does not address address RNA translation which is a high school concept and standard.
If the whole unit is completed I estimate it will take about 11 days. A suggested schedule is included.
Students will enjoy the variety of activities included to learn about genetics, heredity, mutations, natural selection, sexual reproduction and asexual reproduction and trait advantages.
