Over the past few days, 5th graders have been getting a live, up close look at DNA…of strawberries! Students worked with APS science specialist, Jennifer Powell, through a series of steps which extracted the DNA from strawberries.
Students worked hard breaking down the cell membranes of strawberry cells with the use of their hands, and a few other ingredients: rubbing alcohol, salt, and DAWN Dish Detergent. Once those membranes were broken, the DNA was able to be taken from the nucleus of the cells and the result was a clump of DNA! Each student then walked away with a personal momento…a necklace holding the DNA!
