Kinetic energy is usually the entry point for the study of energy in physics and is often perceived as unproblematic. We present evidence, however, that some learners who seem to have accepted the concept, from elementary school students to college physics majors and in-service teachers, nevertheless do not consistently attribute kinetic energy to…

This lesson focuses specifically on teaching concepts of speed and its impact on energy, as well as providing a basic introduction to potential and kinetic energy to fourth-grade students. "Next Generation Science Standards" ("NGSS") 4-PS3-1 states that students should be able "to use evidence to construct an explanation…

This article describes a lesson taught in a designated English Language Learner (ELL) classroom in an elementary school in Pawtucket, Rhode Island, using a sheltered instruction approach. Eighty one percent of the students at this school are from diverse ethnic backgrounds where 25 per cent of them receive ELL services. A variety of languages are…

This article presents the experiences of Miss Felecia McLaughlin, a fourth-grade teacher from the island of Jamaica who used the model proposed by Bass et al. (2009) to assess conceptual understanding of four of the six types of simple machines while encouraging collaboration through the creation of learning teams. Students had an opportunity to…

This effective technique has third- and fourth-grade students explore potential and kinetic energy and explain their discoveries. Students investigate what it takes to make a paint can roll forward and come right back, without seeing inside. Students experience science as an inquiry and develop their critical thinking skills. Students can also…

Ah, springtime, and young people's thoughts turn to... baseball, of course. But this column is not about "how" to throw a curveball, so you'll have to look that up on your own. Here, the focus is on the "why" of the curveball. There are two different things that cause a spinning ball to curve. One is known as the "Bernoulli effect" and the other…

What would happen if social studies student used spaces marked out on the floor and physical movement to learn social studies? Would such a lesson conform with the Vision of Powerful Teaching and Learning in the Social Studies? Students get out of their chairs and away from their desks to perform events within a defined space elsewhere in the room…
