CAROL VORDERMAN M.A. (Cantab), MBE is one of Britain’s best loved TV presenters and is
renowned for her skills in mathematics, and her enthusiasm and encouragement for science
and technology and education. She hosts numerous shows on the BBC, ITV, and Channel 4,
from light entertainment with Carol Vorderman’s Better Homes and The Pride of Britain
Awards to scientific programmes such as Tomorrow’s World. Whether hosting Channel 4’s
Countdown for 26 years or becoming the second best-selling female non-fiction author of
the noughties decade in the UK, reporting to the Prime Minister David Cameron in August
2010 with a far-reaching review “A World Class Mathematics Education for all our Young
People”, Carol has a passion for mathematics and science. Carol was a founding trustee
of NESTA, is patron for the Cambridge Science Festival, member of the Royal Institution,
member of advisory education panel for Engineering, and holder of many honorary degrees
from universities around Britain. In 2010 she launched her own online maths school
www.themathsfactor.com where she teaches parents and children how they can
become the very best they can be in the language of mathematics.
TOM JACKSONhas written nearly 100 books and contributed to many more about science,
technology, and natural history. Before becoming a writer, Tom spent time as a zookeeper,
worked in safari parks in Zimbabwe, and was a member of the first British research expedition
to the rainforests of Vietnam since the 1960s. Tom’s work as a travel writer has taken him to
the Sahara Desert, the Amazon jungle, the African savanna, and the Galápagos Islands –
following in the footsteps of Charles Darwin.
DR MIKE GOLDSMITH has a PhD in astrophysics from Keele University. From 1987 until
2007 he worked in the Acoustics Group at the UK’s National Physical Laboratory and was
Head of the group for many years. He still works with NPL on a freelance basis. Mike has
published more than 40 scientific papers and has written more than 30 science books, two
of which have been short-listed for the Royal Society prize for children’s science books.
DR STEWART SAVARD is the Science Lead Teacher and district eLibrarian/eResource
teacher in British Columbia’s Comox Valley, Canada. Stewart has published papers on the
role of Science Fiction and Science collections in libraries and helped to edit 18 Elementary
Science books. He is actively developing a range of school robotics programmes.
ALLISONELIA graduated from Brunel University in 1989, with a BSc (Hons) in Applied
Physics. She worked in Public Sector finance for several years before realizing that her true
vocation lay in education. In 1992, she undertook a PGCE in Secondary Science at Canterbury
Christ Church College. For the past 18 years, Allison has taught science in a number of
schools, and is currently the Head of Science at Fort Pitt Grammar School in Kent.
Foreword
Hello
Welcome to the wonderful world of science: a world that can take your breath
away. It is sometimes difficult to believe how extraordinary the complex
patterns of nature are, but when science reveals its beauty at so many levels,
it really is easy to become enthralled.
The economic nature of how we live has changed. Now those children who grow
with a passion for science have the world at their fingertips – they will know
wonder like no other… and their opportunities are without limit.
The way in which science can engage children has changed radically, too.
There are so many ways in which you can make this exciting, particularly
at home, and that is the essence of this book.
We are well aware that many parents themselves gave up any study of science
many years ago and might feel wary or even frightened of engaging in the
subject again. We wanted this book to guide all parents through the areas
that your child will study now and in the years to come.
As a single parent with two children, I know just how important it is to say
“wow” to all things scientific, to show your own wonder, even if you don’t know
the answer in full yourself. Science doesn’t need “the right answer” to inspire…
science poses questions. Understand the basics and you may find this
inspiration, too.
I hope that you enjoy this book as much as we have loved putting it together.
