When do photons, electrons, and atoms behave like particles and when do they behave like waves? Watch waves spread out and interfere as they pass through a double slit, then get detected on a screen as tiny dots.

This template is an instructional tool that can be used to guide elementary students (grades 2-5) through the reading strategy of questioning. The template is based on the Question-Answer Relationship (QAR) approach in which students classify questions according to type and then provide answers from text. The template was designed to be used with the Feature Story, The Dance of Life, by students in grades 2-5. It is a PDF document that can be copied and distributed to students.
