In this activity, students learned scientific practices and evidence-based reasoning by formulating and testing hypotheses about factors affecting human reaction time and examining those hypotheses with data from ruler-drop tests. The project aligns with all eight of the science and engineering practices (SEP) embodied in the "Next Generation…

Some of the most important scientific studies are associated with either incredibly large dimensions (e.g., the universe) or extremely small proportions (e.g., the cell). While a teacher's curriculum may often switch from mega-expanses to minutia, they should question how easily students comprehend the change in sizes. This article addresses…

In recent years educators and educational researchers in the U.S. have begun to introduce engineering design activities in secondary science classrooms for the purpose of scaffolding science learning as well as supporting such general problem-solving skills as decision making and working in teams. However, such curricula risk perpetuating a…
