McGowan, Veronica Cassone; Ventura, Marcia; Bell, Philip – Science and Children, 2017
This column presents ideas and techniques to enhance your science teaching. This month's issue shares information on how students' everyday experiences can support science learning through engineering design. In this article, the authors outline a reverse-engineering model of instruction and describe one example of how it looked in our fifth-grade…

Xu, Beichen; Su, Jun; Wang, Weiguo – Physics Education, 2018
Cosmic expansion is an important concept in astronomy. For ease of understanding, astronomers generally draw an analogy between cosmic expansion and the expansion of a spherical surface in 3D space. This study theoretically and experimentally investigates the laws governing the motion of particles on the surface of a balloon during expansion.…

Hancock, James Brian, II; Lee, May – Science Teacher, 2018
Many teachers are confused about how to implement the phenomena-based teaching recommended by the "Next Generation Science Standards" (NGSS Lead States 2013). This article describes one possible approach--purposely repurposing existing activities. This process involves having teachers: (1) Choose a phenomenon that informs the development…

Dale, Keith; Dale, Stephen G. – Teaching Science, 2018
The Australian Curriculum (n.d.) describes chemistry as having three interrelated strands, Science Inquiry Skills, Science as a Human Endeavour and Science Understanding. It also states "... the three strands of the Australian Curriculum: Science should be taught in an integrated way". This article will explore a model for integrating…

Campbell, Todd; Neilson, Drew – Science Teacher, 2016
In this article Campbell and Neilson discuss several design strategies developed or adopted that were found particularly helpful when sequencing a unit that focused on learning about motion and acceleration. Students were expected to predict, observe, and explain why a ball traveled down one ramp faster than the other. Before engaging students,…

Menon, Deepika; Lankford, Deanna – Science and Children, 2016
From the earliest days of their lives, children are exposed to all kinds of sound, from soft, comforting voices to the frightening rumble of thunder. Consequently, children develop their own naïve explanations largely based upon their experiences with phenomena encountered every day. When new information does not support existing conceptions,…

Bruxvoort, Crystal; Jadrich, James – Science Teacher, 2016
Science students should undertake engineering design projects and carry out scientific investigations, as recommended by the "Next Generation Science Standards" (NGSS Lead States 2013). However, studies show that students misconstrue the goals of science and engineering and are uncertain about their respective practices (Gilbert and Wade…

Lotter, Christine; Taylor, Laurie – Science Teacher, 2016
In the 2 day lesson presented in this article, students explain how ionic substances interact in solutions by developing and revising their own explanatory models. The lesson engaged students in three-dimensional learning through creating and revising their own models to explain the interaction of ionic substances and polar molecules in a closed…

Baird, Bill – Physics Teacher, 2014
When students are first introduced to the idea of radioactive decay, a large conceptual hurdle must be overcome. The thought that an object's age has no bearing on the chance it will "die" (decay in this case) on a particular day is completely at odds with biological notions of life and death. Through the use of a simple…

Shultz, Ginger V.; Gere, Anne Ruggles – Journal of Chemical Education, 2015
Traditional methods for teaching the Lewis dot structure model emphasize rule-based learning and often neglect the purpose and function of the model. Thus, many students are unable to extend their understanding of molecular structures in new contexts. The assignment described here addresses this issue by asking students to read and write about the…

Pasley, Joan D.; Trygstad, Peggy J.; Banilower, Eric R. – Horizon Research, Inc., 2016
The Next Generation Science Standards (NGSS) are composed of three intertwined dimensions--disciplinary core ideas, science and engineering practices, and crosscutting concepts--that provide a foundation for what students should know and be able to do at various grade levels. The eight science practices outlined in the NGSS are critical components…

Bouwma-Gearhart, Jana; Bouwma, Andrew – American Biology Teacher, 2015
The "Next Generation Science Standards" (NGSS Lead States, 2013) recommend that science courses engage communities of students in scientific practices that include building accurate conceptual models of phenomena central to the understanding of scientific disciplines. We offer a set of activities, implemented successfully at both the…

Casas, Lluís; Estop, Euge`nia – Journal of Chemical Education, 2015
Both, virtual and printed 3D crystal models can help students and teachers deal with chemical education topics such as symmetry and point groups. In the present paper, two freely downloadable tools (interactive PDF files and a mobile app) are presented as examples of the application of 3D design to study point-symmetry. The use of 3D printing to…

Brown, Patrick – Science and Children, 2014
A rich science learning experience not only captures students' attention but also motivates them to investigate and solve problems and investigate how scientists carry out their work. This article describes how secondary science coordinator Patrick Brown's found success teaching students the nature of science by engaging them in…

Gates, Joshua – Physics Teacher, 2011
Early in their study of one-dimensional kinematics, my students build an algebraic model that describes the effects of a rolling ball's (perpendicular) collision with a wall. The goal is for the model to predict the ball's velocity when it returns to a fixed point approximately 50-100 cm from the wall as a function of its velocity as it passes…
