溫 度 ( 攝氏 ) The temperature changes in each 5mins 時間 ( 分鐘 )
Our result is not very well as we plan before. The temperature rise very slow, the temperature of the water only rise about 9 degree Celsius. And it falls down very quickly. We think the area inside should be small so there will not be able to let the air cooling down the water. And the sand should be put under light before put it into the box, because ths sand is cool if we don’t put it under the light for a while.
