Science diagrams are an integral part of science because they are an important means of conveying and visualizing abstract science content. In recent years, researchers have demonstrated the educational benefits of encouraging students to draw their own conceptual diagrams, rather than focusing on interpreting diagrams given to them. To help…

Long before the "Next Generation Science Standards" ("NGSS") were formalized, sensors and other probeware engaged students in science and engineering practices (Metcalf and Tinker 2004). A new generation of probeware based on modern Internet of Things (IoT) technologies is beginning to expand the ways that students can…

Given that students are constantly communicating and documenting special experiences in their social and private lives with digital devices, we suggest that this behavior could be used to record and deepen learning experiences-such as visualizing reactions at the molecular level-in a chemistry class. An example would be the creation of stop-motion…

Alternative farming techniques are often more efficient and conserve resources more effectively than conventional farming, which can harm the environment with pesticides and synthetic fertilizers (Pimental 2005). To learn the theory, application, and related science concepts of sustainable farming techniques, students can collaborate to create an…

Students who are blind or visually impaired (BVI), like all students, need to conduct scientific investigations that involve measurements and reading experimental procedures. Best instructional practices for BVI students include touch and hearing experiences. Related strategies and tools include electronic textbooks, assistive technologies such as…

This paper describes the multiple school and school science experiences of eight Latina students of Central American descent in a tracked, urbanized, middle school setting. Framed by a sociocultural perspective, I describe how eight seventh and eighth grade Latino girls interacted with school science. Implications for the concept "science for…

Physics First is offered to ninth graders at high schools in Aurora, CO. A unique new asset of this school system is an embedded research lab called the "Innovation Hyperlab." The goal of the lab is to connect secondary school teaching to ongoing university scientific research, supporting the school district's aim to create opportunities to…

One of the greatest challenges in teaching physics is helping students achieve a conceptual understanding of Newton's laws. I find that students fresh from middle school can sometimes recite the laws verbatim ("An object in motion stays in motion..." and "For every action..."), but they rarely demonstrate a working knowledge of…

Hands-on activities are one of the most popular instructional tools that enhance student understandings of the science concepts and enable them to get involved in science practices as well. However, most of science educators underestimate its effectiveness in the classrooms. In order to illustrate how these activities could be utilized for science…

Chemistry students are often introduced to the concept of reaction rates through demonstrations or laboratory activities involving the well-known iodine clock reaction. For example, a laboratory experiment involving thiosulfate as an iodine scavenger is part of the first-year general chemistry laboratory curriculum at Dalhousie University. With…

Biology teachers know how important it is for them and for their students to engage first-hand with nature. Ideally, bringing students to fields, woodlands, and wetlands to observe, explore, and wonder is the best way to stimulate curiosity and practice scientific inquiry. However, for many reasons, field excursions are not always practical or…

Imagine recreating a tsunami's force in a bathtub or exploring the potential of geothermal energy by using steam from a kettle to illuminate a light bulb. These types of activities and more are offered in Matthew Levy and Mario Salvadori's collection of experiments and demonstrations in Earthquakes, Volcanoes and Tsunamis. More than 30 easy and…

Recently, a high school Science Club generated a large number of questions involving temperature. Therefore, they decided to construct a thermal gradient apparatus in order to conduct a wide range of experiments beyond the standard "cookbook" labs. They felt that this apparatus could be especially useful in future ninth-grade biology classes, in…
