Tennis Club
This year has been an excellent year for the tennis club. Last year, we started with 20 members and now we have 45. During the year, many of our members played in competitions at school and for the area. David Markham entered the national championships and came second! Well done, David. Perhaps next year you can win! And then maybe Wimbledon? And about Wimbledon – in July a group of about 25 members went to watch the final and they have only just stopped talking about it. A wonderful year. Let’s hope next year is even better!
Book Club
We have finished the year with five more members than when we started – 15. We are a small club, but we certainly love books! During the year we read 12 different books and had some very interesting discussions. The favourite book of the year was the second book by the Swedish writer Steig Larsson – The Girl Who Played with Fire. We also watched and enjoyed the film. We also have some good news. One of our members – Judith Springer – has written several short stories this year, and you can read two of them in next month’s Writer’s World magazine. Judith isn’t sure if she wants to be a journalist or a novelist. We are sure that she’ll do well in both jobs! Good luck, Judith!
Photography Club
Last year was our first year and it was a very good one indeed! More than 30 students joined the club, and we had members between the ages of 11 and 18! We met every week in the photo studio and learned different techniques for taking photographs and making films. We also learned a lot about different types of cameras. We had some interesting talks by some very good experts too. And of course there was the end-of-year competition. Kenny Summers won this. His photograph was of bees on flowers in a field near his home. Congratulations, Kenny! You can see all the photographs from the competition on the club website on www.photosclub.com. And if you’re interested in joining next year, please contact Clive on the website.
