DNA is a very abstract concept that can be difficult to grasp. With this DNA kit, extract "chunks" of DNA from strawberries and papaya that your students can actually see. Students will learn about cell walls and cell membranes since to extract DNA, these walls and membranes must be broken down. Each kit contains 16 sets of materials for students to work in groups of 2 or more.
