On January 31, we went to the national park in Haarlem to collect sand for the greenhouse experiment. We prefer sand in nature because it has more nutrient and microorganism, which is good for plants to grow and flower, compared with pure sand bought from factory. For this trip, we, especially Jerry, have prepared for a long time, contacting with people in the national park to get the permission, choosing a suitable way to deliver sand, buying many things, such as gloves, shovels, and of course, hoping for a good weather.
During the work everyone looked so energetic, especially Martin who worked like a young man. I finally understand why Jerry and Ineke often told me that Martin likes field work very much. We finished the work in almost two hours, after that everyone was pretty tired, so we went to Martin’s house to have a good rest and enjoy some coffee and cakes, then we went back waiting for the truck which help us transport the two big bags of sand to the greenhouse. In a word, this was a really nice and meaningful trip, all of us felt happy although quite tired, at the same time, I was quite grateful for everyone’s kind help.
