Students in this block of measurement have been busy inside and outside: body parts, desks, classroom objects, and our playground have all been food for thought. This week, second and third graders each made their own spring scales and have had fun exploring and weighing objects that are very heavy, very light, and everything in between. We have also been conducting phenomenological experiments! That means observing a particular process and noting the outcome without judgement. When the experiment is complete and all observations have been made, conclusions are drawn and discussed. This is quite different from a typical science lesson. Instead of telling the children beforehand what outcome they can expect and should record, students are encouraged to use all their powers of observation to see what happens in a particular process. It is an exciting and engaging way to study the world around us, and one that develops free thinking.
