This article looks at how the nature of truth in science is not absolute and in accepting the idea that certain 'laws' are sufficiently true we can unlock the rigidity of discipline-based scientific thinking to make the possibility of tackling many of the grand challenges facing society a reality. The nature of Open Science is focused on the fact…

Engaging students in the study of genetics is essential to building a deep understanding of heredity, a core idea in the life sciences (NRC 2012). By integrating into the curriculum the stories of famous scientists who studied genetics (e.g., Mendel, Franklin, Watson, and Crick), teachers remind their students that science is a human endeavor.…

Recommended changes in use of cyclohexane conformers and their nomenclature will remedy inconsistencies in cyclohexane conformers and their nomenclature that exist across currently used organic chemistry textbooks. These inconsistencies prompted this logical analysis and the resulting recommendations. Recommended conformer names are "chair",…

Determining the acceleration of a free-falling object due to gravity is a standard experiment in physics. Different methods to do this have been developed over the years. This article discusses the use of video-analysis tools as another method. If there is a video available and a known scale it is possible to analyse the motion. The use of video…

Student attitudes about learning science and student ideas about the nature of science were compared at the end of two astronomy courses taught in Fall 2007, a course with a traditional astronomy curriculum and a transformed course, whose traditional astronomy curriculum was supplemented by an embedded curriculum that explicitly addressed the…

A WebQuest is an Internet-based and inquiry-oriented learning activity. The aim of this work is to outline the creation of a WebQuest entitled "Power Generation Plants: Steam and Gas Turbines." This is one of the topics covered in the course "Thermodynamics and Heat Transfer," which is offered in the second year of Mechanical…

It is no secret that many high school students are fascinated with automobiles. The activities in "Fueling the Car of Tomorrow"--a free high school science curriculum, available online--(see "On the web")--capitalize on this heightened awareness and provide relevant learning opportunities designed to reinforce basic physics, chemistry, biology,…

The collision model is frequently introduced to describe electronic conductivity in solids. Depending on the chosen approach, the introduction of the collision time can lead to erroneous results for the average velocity of the electrons, which enters the expression for the electrical conductivity. In other textbooks, correct results are obtained…

Supermarket Botany is a frequently-used teaching resource or strategy. It draws on a student's existing familiarity with plant-based foods to explore plant structure and life cycles. One of its strongest points is that it is adaptable to many age levels--from lower primary school to university and general interest groups. We have designed a unique…

Students are scientifically literate when they can read material about science and intelligently communicate their viewpoints, comments, and critiques, using scientific vocabulary and applying the ideas of the process and nature of science. As part of their normal class, 80 students were asked to find an article on the internet, read it, and then…

Finite element modelling software has been used to allow secondary school students to study nanoscale magnetic materials for hard drive recording applications. The students were introduced to the basic concepts of finite element modelling using a freely available internet game before modelling the magnetization reversal of single magnetic grains.…

The hydrologic cycle is a very basic scientific principle. In this article, background information is presented on how the hydrologic cycle provides scientists with clues to understanding the history of Earth's climate. Also detailed is a web-based activity that allows students to learn about how scientists are able to piece together a record of…

The declining cost of computers and wireless networks has made laptop programs more affordable than ever. At the same time, the internet resources available to teachers and students have grown exponentially in the 15 years since web browsers first became practical. As a result of these trends, growing numbers of students nationwide are provided…

Since Robert Millikan discovered the quantization of electric charge and measured its fundamental value over 90 years ago, his oil-drop experiment has become essential in physics laboratory classes at both the high school and college level. As physics instructors, however, many of us have used the traditional setup and experienced the tedium of…

It is widely accepted that inquiry-based curriculum programs have positive effects on cognitive achievement, process skills, and attitudes toward science (NRC 2000). Science teachers seek engaging, effective, and inquiry-based activities that are standards-aligned and convenient to implement in their classrooms. For many years, the web has…
