Abstract

Many students wrongly presume that scientific knowledge is mysteriously discovered and often believe the development of this knowledge is beyond their ability to comprehend. The activity presented here – appropriate for high-school chemistry and physics students – challenges these misconceptions. Students are engaged in thinking and creativity similar to how the first scientists accurately measured the mass and charge of an electron. Through this process, students develop a deep understanding of how the mass and charge of an individual electron was determined. This activity addresses National Science Education Standards A, B, E, and G and Iowa teaching Standards 1, 2, 3, 4, 5, and 6.
