Year 10 Science

So far this term, we have been investigating the wonderful world of DNA and Genetics in Year 10 Science. Throughout this study, students have learnt the how and why of DNA as a blueprint for controlling the characteristics of organisms and how that genetic information is passed onto offspring from both parents by meiosis and fertilisation. They have also explored the effects of mutations and the applications of gene technologies such as gene therapy and genetic engineering. They discussed the use of genetic testing for decisions such as genetic counselling, embryo selection, identifying carriers of gene mutations and the use of this information for personal use by organisations such as insurance companies or medical facilities. Finally, they are now able to explain how fast computing and ICT have enabled the analysis of large amounts of DNA sequence information in the field of Bioinformatics.

As part of this area of study, students needed to have a clear understanding of the structure and composition of DNA. To consolidate their theoretical knowledge, we combined experimentation and modelling with gastronomic delight. Students were given two types of liquorice and four flavours of soft lolly and asked to create the double helix structure of DNA with accurate representation of the phosphate and sugar backbone, with the four nitrogen rich bases organised in the complementary pairing. Student were required to present their model to their teacher before consumption so that the accuracy of their model could be confirmed. This was a fun and interactive way to apply their knowledge, with fantastic results and plenty of smiles.  

Well done Year 10s.
