Grades 6–12 (Kit)
Extract DNA you can see! Students will discover that DNA isn’t just a concept in a textbook—it’s a tangible part of the food they eat. This hands-on kit guides students through extracting visible strands of DNA from strawberries, allowing them to observe the genetic material that carries the instructions for life.
Perfect for biology or biotechnology units, this memorable activity helps students connect genetics to real-world agriculture and careers in science. Kit includes enough supplies to create 100 DNA necklaces, so every student can wear their science experiment home.
