Methods: On September 29, 2016 students used sweep nets and transects to sample insect communities and populations in the grasslands. Transects were placed randomly all over the grasslands, lab mates would walk the entire transect (30 metres) while sweeping within one metre on both sides of the transect. Lab mates would then proceed to carefully examine the sweep net and take account of how many total insects there were and how many different species there were.<br>Study site: The study took place at York University's Grassland. The lab was outdoors, and the weather was very cloudy.<br>Hypothesis:The more time it takes to go from one end of the transect to the other end, the more abundance of an insect population gets captured by the sweep net. <br>Predictions:1) Insects of the same species will be in small groups together,and so if you walk faster,you would be spending less time collecting bugs in one small area thus not getting many of the same species of insect 2) The amount of time spent in going through the transect has no effect on how much of an insect population is collected. A reason for this may be that some insect species do not stay together<br>Meta-Data:Attributes:1)Total number of insects: Numerical2) Total number of different species: Numerical<br>Group members: Brenda Espin, Kiana Malak Hosseini, Shunelle Prasad<br>

实验方法：2016年9月29日，实验学生采用扫网（sweep nets）与样带（transects）法对草原生境中的昆虫群落及种群进行采样。样带随机布设至整片草原区域，实验组员沿整条30米长的样带行进，同时在样带两侧各1米范围内开展扫网操作。随后实验组员仔细检视扫网所得样本，统计昆虫总个体数及不同物种的数量。
实验地点：本实验于约克大学（York University）草原生境开展，实验场地为户外环境，当日天气为多云。
实验假设：从样带一端行进至另一端的耗时越长，扫网所捕获的昆虫种群丰度越高。
实验预测：1）同一物种的昆虫会以小种群集群栖息，因此若行进速度较快，则在单一小区域内采集昆虫的耗时更短，从而捕获的同物种种群个体数较少；2）通过样带的耗时对采集到的昆虫种群数量无影响，该现象的潜在原因可能为部分昆虫物种并不集群栖息。
元数据：属性项如下：1）昆虫总个体数：数值型；2）不同物种总数：数值型。
实验组成员：Brenda Espin、Kiana Malak Hosseini、Shunelle Prasad。
