NYS Learning Standards:

MS-LS1-5. Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.

MS-LS3-1. Develop and use a model to explain 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.

MS-LS3-2. Develop and use a model to describe how asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation

MS-LS4-5. Gather and synthesize information about the technologies that have changed the way humans influence the inheritance of desired traits in organisms

Content/ Skills Taught:

Students will be able to

1. Explain the function of DNA and protein synthesis
2. Predict how mutations are beneficial, harmful or no effect
3. Identify different types of technology that influence genetics

Areas for Differentiated Instruction:

Various levels of activities- 3 versions for low, mid and high level

Learning Activities:

• Draw a DNA and label all parts including how to make a protein
• Complete an experiment with a strawberry to see what DNA looks like
• Use a punnett square to predict traits from parent to offspring
• Create a pedigree family tree

Assessments:

One short quiz: estimated 10-15 questions

Unit One test: estimated 30 questions with 2 essay questions

Resources:

• PowerPoint notes
• Guided notes
• Lab packets
