ABSTRACT
Newtonian physics is an area of science that is part of the curriculum in middle and high schools throughout the country. It is easy to set up demonstrations of physics principles that are easy to observe and provocative to talk about. Students drop objects of different size or weight and wonder whether they hit the pavement at the same time. They observe how objects float in water, how objects collide, and how moving objects land at particular locations. Some of what the students see is counterintuitive, which ideally stimulates them to ask questions and perform mini-experiments to answer the questions. Students discuss what they see and learn with their peers and teachers.
