今天是9月29号，一如既往的早餐之后，我们九点准时出发向第一个目标Canadian museum of nature进发。在那里由一个从QUBS毕业在那里工作的前学长带领我们参观，由于有内部人员所以我们可以幸运的参观非展出区。由于空间比较小，我们先分为两组分别由鸟类展区和鱼类展区参观再汇合参观标本库，植物展区，DNA实验室和3D扫描工作室。在鸟类展区我们看到了很多鸟类的标本，我们惊讶于其保存的完整性，因为有很多鸟类的标本都是19世纪和20世纪初制作的。工作人员说低温与无光是使标本保存完好的重要条件，低温也可以抑制虫类的活动，对于标本的保存有利。在最后我们到了一个展柜前，拉开后发现有很多漂亮的鸟类，但当告之这些种类都已经灭绝了，都很遗憾。鱼类展区我们了解了整个展区的基本构造，保护措施以及标本的实际用途。最开心的当属在标本库里，许许多多鹿和牦牛的头挂在墙上，巨大的牦牛头和形态各异的鹿角，大家都兴奋的与其合影，还有黑猩猩的标本，北极熊皮和大量的鹿皮等，但为了妥善保存这些东西，标本库的温度是如此的低，真心冷啊。DNA实验室里，学长为我们展示了如何利用DNA分析方法来构建进化树，我发现这里的一个离心机和复旦实验室里用的是一样的，很亲切。3D扫描仪是个很神奇的东西，可以快速完整的将小型的化石或者标本的3D图像扫描到电脑内成像，而且运用软件可以进行残缺的化石影像修复进而制造出完整的模型，so 神奇！
五点我们出发去了今天的最后一站，其实也是Canadian museum of nature啦，不过上午参观的是类似于工作室，晚上去的是真正向人们开放的博物馆。看到了各种的恐龙化石，远古的哺乳动物，站在一个曾经最大的陆地哺乳动物身下，我的头还碰不到它的肚皮，据说有4头非洲象那么重！！还看到了一个未成年的蓝鲸骨骼，虽然说是未成年但也很巨大，有19米长，真正成年的蓝鲸大约33米，如此巨大的生物亲眼见到还是很震撼的！在回来的路上是一路睡过来的，睡了两个小时……虽然很累但今天很充实也很开心，虽然现在还在苦命的写blog……期待以后每天的活动，相信都会如此精彩！
Today was Sep, 9th. After the breakfast, we set out for the first destination the Canadian Museum of Nature. Roger who graduated from QUBS lab guided us as a staff of this museum, thus we could visit non-display area fortunately. We were divided into two groups to be showed the birds and fish exhibition and then gathered to visit bonus section (stored so many yaks’, deer’s and polar bears’ samples and leathers), plants exhibition, DNA lab and 3D scanning office. We were so amazed at the integrity of many birds’ sample made in 19th century in the bird exhibition. The professor told us that low temperature and lightless were the critical factors influenced the integrity of samples, for low temperature inhibiting insects’ activities. Finally, we came to the front of a cabinet with so many beautiful birds, however, it was so sad to know that these beautiful birds had extinguished already. We should do more to protect creatures on the earth. Arriving at the fish exhibition, we knew the basic structure, protection measure and practical application of samples. The most exciting was in the bonus section, storing so many heads samples of yaks, antlers and leathers of polar bears and other animals there. Guys took photos excited and happily. However, it was so cold in there for storing these samples well. Roger showed us how to make an evolution tree by DNA analysis method, and the centrifuge I found in the lab was the same as the on
It was two o’clock when we got out of the museum, then we drove to the Byward Market having lunch. It was the first time getting into a city since we arrived at Canada. After having lunch, we went to the Parliament Hill, seeing the great hall and taking part in an activity, throwing a coin into fire and praying, which was the same as some activities in temples in China.
The last destination we went to today was another part of Canadian museum of Nature. The part in the morning was office, and we went to the real museum opened to public in the evening. We saw many kinds of dinosaur fossils and ancient mammals. Standing under the ever largest mammal, I can’t touch its belly. We also saw a skeleton of young blue whale, it was as long as 19meters. It was said that a blue whale could be as long as 33 meters, it was really stroke when you witnessed the giant. It was so happy and tired today, expecting the activities in the followed days!!
