Marlborough student tops the class in Taiwan

DMarlborough student tops the class in Taiwan

Marlborough Girls' High School student Kali Stratford has taken first prize in the international physics class of the Taiwan Science Fair. Kali's entry, an investigation into the effect of the height of the net on rallies in table tennis, won the IPENZ Award at the 2002 Genesis Energy National Science and Technology Fair. This award provided her with travel to the Taiwan Science Fair.

Kali, who only returned from Taiwan yesterday, said she would always remember her experiences there. She especially enjoyed was meeting students from other countries and experiencing their cultures, she said, and made life-long friends. While she was there she stayed with a host family who took her to see many of the tourist attractions in Taiwan.

Her investigation is described below. She won a handsome trophy and a digital camera for being awarded "fist place".

Table tennis, the fastest ball sport in the world, has become so fast that rallies have become very short. Kali investigated the effect net height has on speed of the ball, spin and rally length. She found that increasing the height of the net by up to 10cm decreased the speed and spin; as a result rally length was increased. Speaking from Taipei, Kali said that there had been much interest in her investigation, clearly demonstrating that net height has a significant effect on the length of the rally in table tennis.

Kali, a Year 11 student at Marlborough Girls' High School, is studying this year for the NCEA

Kali's phone number is 03 578 6822. For any other information please contact Debbie Woodhall, Royal Society of New Zealand, 025 229 6380.
