PRODUCT DESCRIPTION

Super simple STEM LAB & PRELAB using household materials that will allow students to extract plant DNA from various sources. 7 PAGES with teacher notes and instructions. EDITABLE! This can be adapted for younger grades as well. Best sources have been the strawberry, kiwi and banana.

STUDENT RELEVANCE******************************************************

Great way to introduce GENETIC ENGINEERING with the following scenario in the lab:

WOULD YOU LIKE TO HAVE LIPS THAT TASTE LIKE STRAWBERRIES, KIWI or HOT PEPPERS? All you need to do is extract the DNA from these plants, isolate the flavor gene, and insert it in all the cells of your lips!!!!!

This lab would be the first step in being able to genetically engineer your cells to have traits similar to other organisms. DNA is present in the cells of all living organisms. This procedure is designed to extract DNA from various DNA sources in sufficient quantity to be seen and spooled.

RELATED LESSONS********************************************************

Great activity to do after they build models. Here's my lesson on DNA model building that uses biodegradable packing peanuts:
NGSS Packing Peanut DNA Models

Another lesson that I do after these two is one on DNA and the effects of UVB radiation on replication, transcription and translation. Here's the link:
DNA: Replication, Transcription and Translation
