We present a tool, one that is both a stand-alone web-based video game and a Python package, designed for students to explore a particle's wave function on one-dimensional potential surfaces. The tool relies on a basis set formalism and can, therefore, explore any one-dimensional potential surface imaginable. This tool also lets students interact…

Computational thinking is a contemporary science and engineering practice that has been introduced to the US science classrooms due to its emphasis in the "Next Generation Science Standards" (NGSS). However, including computational thinking into science instruction may be challenging. Therefore, for biological evolution (an essential…

Science teachers need to evaluate their lessons and units of study, frequently, to stay abreast of recommended trends in the curriculum. Self evaluation is involved here. A quality science program must be implemented in order to assist learners to achieve as optimally as possible. Which guidelines should then serve in self evaluation?

This work describes an effective, low cost method to anodize small aluminum objects. The use of a PVC spacer between the anode and cathode significantly reduces the size of the electrochemical cell and electrolyte required for its operation. Students will explore the physical and chemical properties of aluminum and anodized aluminum. They will…

In this undergraduate analytical chemistry experiment, students quantitatively assess the antibacterial activity of essential oils found in thyme leaves ("Thymus vulgaris") in an authentic, research-like environment. This multi-week experiment aims to instill green chemistry principles as intrinsic to chemical problem solving. Students…

An astronomy "experiment" composed of three parts is described in the article. Being given necessary data a simple model of inner planets of the solar system is made in the first part with planets' circular orbits using appropriate scale. In the second part revolution of the figurines used as model representations of the planets along…

Learning science is language intensive. Students might have to interpret the meaning of models, support claims with evidence, communicate arguments, and discuss phenomena and scientific principles. For English Language Learners (ELLs), engaging in scientific and engineering practices includes additional challenges. This article describes a series…

The National Assessment of Educational Progress (NAEP) measures student science achievement nationally, state by state, and, most recently, across selected urban school districts. Periodically, the framework underlying the science assessment is revised or updated. This document, "Science Framework for the 2019 National Assessment of…

Thanks to their unique physicochemical properties (e.g., surface plasmon resonance), noble metal nanoparticles are at the cornerstone of nanotechnology. Silver triangular nanoprisms are presented here as an ideal playground to introduce students to nanochemistry concepts such as the formation of shape-controlled nanostructures. Not only a reliable…

The Next Generation Science Standards ("NGSS") were developed by teachers, scientists, and leaders in science and science education from around the country and are endorsed by the National Science Teachers Association (NSTA), a partner in the development of the "NGSS." This article presents an example of how to modify a lab to…

Noby Leong is a PhD student in Chemistry at University of Adelaide working on the design of new drug delivery systems for medical applications. He's also a science communicator, part of the volunteer blogging community at RiAus and curator of his own blog "The Other Side of Science." In this article Noby shares the highs and lows that…

In 2012, the United Nations General Assembly declared 2014 the International Year of Crystallography. Throughout the year 2014 and beyond, all the crystallographic associations and societies active all over the world are organizing events to attract the wider public toward crystallography and the numerous topics to which it is deeply interlinked.…

This article discusses the resources available for teachers to apply higher-level thinking and cognitive complexity to their instruction and assessments. While designing higher-level assessments might be a challenging task, doing so not only can improve student achievement in science, it also prepares students for a changing world. Students learn…

This is an abridged version of the "Science Framework for the 2015 National Assessment of Educational Progress." The National Assessment of Educational Progress (NAEP) and its reports are a key measure in informing the nation on how well the goal of scientific literacy for all students is being met. The framework reflects the nature and…

The National Assessment of Educational Progress (NAEP) and its reports are a key measure in informing the nation on how well the goal of scientific literacy for all students is being met. The "Science Framework for the 2015 National Assessment of Educational Progress" sets forth the design of the NAEP Science Assessment. This document is…
