DNA: Taking a Closer Look
The first unit of work our Year 10 Science classes are exploring this year includes DNA and Genetics, and discovering what makes us who we are.
The Year 10s started by exploring the structure of Deoxyribonucleic acid (DNA), and the genetic information which it contains that is responsible for the development and function of living organisms.
As part of this learning, our Year 10 students completed a practical experiment where they used common materials to isolate the DNA in strawberries and kiwi fruit. Students began by using household detergent to break down the cells in the fruit. They then used salt to separate the proteins from the DNA, and alcohol to clump the DNA together, allowing the DNA to be visible.
Once the DNA was isolated in their mixture, the students used their scientific inquiry skills to investigate the DNA, completing a practical laboratory report.
After studying online, the students had a fantastic time working together in the lab to complete this practical, demonstrating the amazing way which God has wonderfully created strands of DNA to meet each individual’s need.
“I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well.” – Psalm 139:14
