Abstract

This paper concerns the implementation and evaluation of a Teaching Learning Sequence (TLS) for the content of Nanoscience-Nanotechnology, focusing on the concept of the Size of objects and the Observation tools. The participants were sixth grade primary school students. Data collection involved questionnaires and interviews conducted before and after the implementation of the TLS. The results show that after the implementation, a large number of students reported that the smallest object they think exists is a nanoworld object. They also correctly classified objects in the macroworld, microworld and nanoworld based on the corresponding observation tool and correctly ordered objects from largest to smallest.
