We learned all about DNA and some of the scientists who have contributed to our understanding of it. Having studied the structure of a DNA molecule by looking at the work of Rosalind Franklin and Nobel prize winners Watson and Crick, we created our own double helix DNA molecules using sweets!
Following on from this, we looked at how genetic mutations in DNA structure can give rise to certain traits which allow some species to survive by adapting to their environment. We used our new knowledge to conduct a beak adaptation experiment. Candy worms and M&M seeds were the plentiful food source in our imaginary habitat. Students had to design a beak best suited to the available food source. Those who gathered enough food survived! This gave depth to our understanding of the link between adaptation and evolution, and cemented our understanding of the phrase, ‘Survival of the fittest.’
