Strawberry DNA Extraction

Your students may never look at strawberries the same way again! This activity is designed mainly to introduce students to DNA. A discussion of how this DNA extraction procedure works might also touch on the plant cell wall, the cell membrane, proteins, and DNA’s lack of solubility in ethanol. The activity supports 3-dimensional learning and builds toward the following:

• NGSS Scientific and Engineering Practices: Constructing Explanations, Developing and Using Models
• NGSS Core Idea: Life Science 3: Heredity: Inheritance and Variation of Traits
