Objective: The purpose of this lab is to allow you to become familiar with a procedure for extracting DNA‚ collecting DNA samples‚ and to observe the physical characteristics of DNA Background: The wild strawberry is a diploid because it only has two sets of chromosomes. While the grocery store kind is an octoploidy because it has eight sets of chromosomes. The reason we chose the grocery store strawberry is because we’d be able to extract more DNA. Ripe strawberries make enzymes which help break

October 13‚ 2012 Needle through a Balloon Pre-Lab Preparations: Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin. Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden
