We develop an Easy Java Simulation (EJS) model for students to experience the physics of idealized one-dimensional collision carts. The physics model is described and simulated by both continuous dynamics and discrete transition during collision. In designing the simulations, we discuss briefly three pedagogical considerations namely (1) a…

Promotes the use of humane education as a vehicle for teaching students how to make bar graphs. Provides ideas for bar graph activities for both primary- and intermediate-grade children that focus on different kinds of domestic and wild animals. Suggests expanded types of graphing activities involving survey techniques. (TW)
