The purpose of this lab was to identify and compare the number of insects in each quadrat of the grassland and woodlot. The data of this experiment was collected from the grassland lot located at York University Keele Campus (43.7 degrees North, 75.9 degrees West), between York Blvd and Keele St. at 3:00pm. It was 22°C outdoors in the grassland and woodlot. very sunny and quite chilly. The quadrat was randomly placed on the ground in the grassland and woodlot, and the total number of living insects of different species in total in the quadrat were counted by observation and recorded in a table. The quadrat was randomly placed in 10 different spots in the grassland and woodlot and the data were all recorded on the same table for each quadrat, for a total of 20 trials. All the data was collected in a notebook. The experiment was 30 minutes long. Each of the 20 quadrats used in the experiment was measured using measuring tape. Each quadrat had an area of 1m², therefore a total of 20m²of quadrats were used. It was hypothesized that there would be higher number of insects in the grassland while the woodlot would have a lower number of insects. The data supports the hypothesis. Since there is direct sunlight, more grass as well as higher pollination rate of the plants occurs in the grassland compare to the woodlot, there are more insects in grassland than woodlot. <br> <br>

本实验旨在识别并比较草地与林块（woodlot）每个样方（quadrat）内的昆虫数量。本次实验的数据采集于约克大学基尔校区（York University Keele Campus）的草地样地，该区域坐标为北纬43.7度、西经75.9度，地处约克大道（York Blvd）与基尔街（Keele St）之间，采集时间为当日下午3时。当时草地与林块区域的户外气温为22℃，天气晴朗但体感较为寒凉。研究人员采用随机布设的方式将样方置于草地与林块的地面上，通过目视观测统计样方内所有不同物种的活体昆虫总数量，并将数据记录至表格中。本次实验在草地与林块中各随机布设10个样方点位，每个样方的实验数据均记录于同一张表格中，总计完成20组采样。所有实验数据均记录于实验笔记本中，单组实验的持续时长为30分钟。本次实验所用的20个样方均通过卷尺（measuring tape）进行尺寸测量，每个样方的面积为1平方米（1m²），因此本次实验总计使用的样方面积总和为20平方米（20m²）。<br><br>本实验预先提出假设：草地样方内的昆虫数量将高于林块样方。实验数据验证了该假设。相较于林块，草地可接收直射阳光、植被更为茂密，且植物授粉率更高，因此草地中的昆虫数量多于林块。
