6th, Banana DNA Extraction Lab | Hands-On Genetics | NGSS | Grades 6-8

This banana DNA extraction lab is the ultimate hands-on genetics activity for 6th, 7th, and 8th grade life science and biology students studying DNA structure, cell membranes, and heredity. Aligned with NGSS MS-LS3-1 and MS-LS3-2, this no-prep science lab uses common household materials to let students extract and observe real visible DNA — making abstract concepts like chromosomes, genes, and cell biology tangible and exciting. Teachers searching for a middle school biology lab, inquiry-based science activity, or hands-on NGSS lesson will love that everything is included — procedures, student observations, extension questions, real world connections, and a full answer key.

What's included:

• Lab overview with at-a-glance info table
• Full materials list (per group of 3-4 students)
• Safety precautions
• Step-by-step procedures (5 parts)
• Student observation questions with drawing prompt
• Extension questions
• Real world connections (forensics, medicine, environmental science)
• Complete teacher answer key

Perfect for:

• 6th, 7th, and 8th grade life science and biology
• NGSS MS-LS3-1 and MS-LS3-2 aligned instruction
• Hands-on and inquiry-based learning
• Homeschool families
• Sub plans — no prep needed
• End of unit labs and review

Students will extract and observe real DNA from banana cells using dish soap, salt water, and cold rubbing alcohol — and walk away truly understanding how DNA is structured inside living cells! 🧬
