任务分配 - 详细说明

Method:

公平的测试 - 薯片脂肪含量 观看任务分配影片,获取有关此项测试的帮助。除了经常锻炼之外,均衡饮食也很重要。此项公平的测试帮助学生认识薯片含有多少脂肪。首先,取一些样本薯片。把它们放在一些格纸上,在上面铺一张厨房纸。用擀面杖把薯片擀碎。清理掉格纸上的碎屑,看看哪些方格里有油。在有油的方格周围,用彩笔画出大致的轮廓线/在这张纸的其他部分,或者用不同的格纸,对其他薯片样本重复以上步骤。完成后,小朋友们应该能够判断出哪种薯片含油最多,或者分别数出有油的方格数。为了拓展,小朋友们可以比较他们的测试结果与薯片包装袋上标注的脂肪含量。有油的方格树最多的薯片是脂肪含量最高的吗?小朋友们应该确定如何使这个测试更加公平。建议如下:称量每个薯片样本的重量 用擀面杖把薯片擀碎相同的次数 每袋只用一个薯片 然后,小朋友们应以条形图的形式展示他们的结果。题纸中的任务有所不同,可以满足不同的学习需求。

Teacher Mastery

The Science Behind the Science
Scientists use averages because it removes any outliers that may have occurred during an experiment. By repeating a test multiple times and calculating an average of the results, scientists can be more confident in their final conclusion. 

Calculating the range of results from an experiment also helps increase confidence in results. For example, if two experiments were carried out and the first experiment had an average of 10.7 and a range of 2.1 to 18.6 and the second experiment also had an average of 10.7 but its range was from 9.5 and 11.4, then we would be much more confident about the results from the second experiment because they are closer to the average.
