Did you organize Science Day Festival on April 21st? In South Korea, there is science day on April 21st. In addition, science month is in April. We designate this day to Science day to recognize the development of Science technology. It celebrates Science and Technology Agency independence from central administrative agency. The school or related group hosts many contests on this day.

In our school, we also had several competitions and many activities like air rocket show, science essay writing contest, science debate contest, and ‘Kapla’ contest. Among them, and I joined ‘Kapla’ contest.

‘Kapla’ is a kind of block game. It sounds unfamiliar to most students, but it originated in Netherlands. It is a compound word of ‘kabouter’, which means magic and ‘Plankues’, which means boards. It is making a work or a construction with the same size of wood blocks. The golden ratio of Kapla block is 3:5:15. To win the game, players should build the most balanced structure based on the golden ratio.

In our school, we did this project in group with two people. We made mini town by using wood blocks. I planned and designed what to make, and tell other teammates how to make them. While we built the structure, it was about to fall down several times. To make the perfect balanced structure was not an easy task, but we didn’t give up. Finally, we completed the wood block town. Our group won the second prize in that competition.
