The DNALC Strawberry DNA Extraction Kit transforms the abstract concept of DNA into something concrete. It is easy to use and safe enough for young students while being interesting and informative enough for older students. The comprehensive manual makes lesson planning easy.

Product Details
Beginning—Easy to perform; requires little or no prior knowledge.

In this exciting activity students are introduced to DNA, literally, by removing it out of a strawberry! Using a technique like those used by scientists, this kit is an easy and fun way to teach DNA and cell structure and function that is appropriate for all grade levels.

Learning Objectives

• Use evidence to construct an explanation that all living things are made of cells, and therefore must contain DNA.
• Understand cell wall and cell membrane composition.
• Understand how cell barriers are broken and how to extract DNA from strawberry cells.
• Develop a model to describe a causal account for the precipitation of DNA and the visualization of microscopic structures within the plant cell.
• Use a model to describe how the structure of the plant cell wall, cell membrane, and nuclear membranes function together to compartmentalize cell function and to control what enters and leaves the cell.

Prerequisite Knowledge and Skills
Students should be familiar with the basic structure and function of eukaryotic cell organelles, the fluid mosaic model of the cell membrane, and the packaging and structure of DNA.
