Each year the Royal Society awards a prize to the best book that communicates science to young people with the aim of inspiring young people to read about science. In the run up to the announcement of the winner of The Royal Society Young People’s Book Prize in the middle of November, I’ll be reviewing the books which have made the shortlist, and trying out science experiments and investigating the world with M and J in ways which stem from the books in question.
Have you ever thought how your genes could get you out of prison?
Or what the consequences might be if a company owned and could make money out of one of your own genes?
How would you know if you were a clone?
Why might knowing something about junk DNA be important if you’re running an exclusive restaurant with slightly dodgy practices?
Answers to these and many other intriguing questions are to be found in this accessible introduction to genetics, pitched at the 9-11 crowd. Arbuthnott does a great job of showing how relevant a knowledge of genetics is, whether in helping us to understand issues in the news (e.g. ‘Cancer gene test ‘would save lives’‘) or understanding why we are partly but not entirely like our parents. What makes you YOU? covers key scientists in the past history of genetics and crucial stages in its development as a science, including the race to discover what DNA looked like, the Human Genome Project, and Dolly the Sheep.
Arbuthnott portrays the excitement and potential in genetic research very well, leaving young readers feeling that this is far from a dry science; there are many ethical issues which make the discussion of the facts seem more relevant and real to young readers. Whilst on the whole I felt the author did a good job of balancing concerns with opportunities, I was sorry that in the discussion about genetically modified plants no mention was made of businesses ability to control supply to food stock, by creating plants which don’t reproduce, leaving farmers dependent on buying new seed from the business.
A timeline of discoveries, a very helpful list of resources for further study, a glossary and an index all make this a really useful book. Importantly, not only does the book contain interesting and exciting information, it also looks attractive and engaging. Lots of full bleed brightly coloured pages, and the use of cartoony characters make the book immediately approachable and funny – a world away from a dry dull school textbook.
What makes you YOU? provides a clear and enjoyable introduction to understanding DNA and many of the issues surrounding genetic research, perfect not only for learning about this branch of science, but also for generating discussion.
Extracting DNA is what the kids wanted to try after sharing What makes you YOU?. In the interest of scientific exploration we tried two different techniques to see which one we found easier and which gave the best results.
Method 1: Extracting your own DNA
What you’ll need:
We learned this method for extracting DNA from Exploratopia by Pat Murphy, Ellen Macaulay and the staff of the Exploratorium. Unfortunately it’s out of print now, but it is definitely worth tracking down a copy if you are interested in doing experiments at home.
Method 2: Extracting strawberry DNA
This second method is detailed in What makes you YOU? and involves strawberries, fresh pineapple, warm water and ice as well as washing-up liquid and salt. It also calls for methylated spirits but we swapped this for surgical spirit, as that’s what we had to hand.
This method is a little more involved than the first method but is a all round sensory experience: There are lots of strong smells (from crushed strawberries and puréed pineapple, as well as the surgical spirit), colours make it visually very appealing (perhaps this is why methylated spirits are called for in the original recipe as the purple of the meths adds another dimension) and there is also lots to feel, from the strange sensation of squishing the strawberries by hand, through to the different temperatures of the warm water in which the DNA-extracting-mix gently cooks followed by the ice water in which it cools down.
Look! Strawberry DNA!
Both methods were fun to try. We liked the first method because the result was seeing globs of our very own DNA, but the second method was a much more stimulating process, appealing to all the senses. Indeed this DNA extraction recipe alone makes it worthwhile seeking out a copy of What makes you YOU?.
Whilst extracting DNA we listened to:
