Science popularisation festivals attract more and more people every year, showing that there is a need to satisfy public curiosity. Such events are good occasions to disseminate knowledge to a large audience. The results of scientific research bring advances for mankind. Since research mostly depends on public funds, it is important to gain…

The aim of the study was to explore the types and sources of positive emotions experienced by first year university students studying to become primary school teachers, during collaborative science learning. Fun science activities, designed to enhance students' motivation for science, provided the context for examining the relationship between…

Some physiological concepts, such as physiology of filtration and absorption in the different nephron segments, are so detailed that they can be a challenge to be memorized. This article describes an exercise that solidifies learning as students manipulate, using paper models, "transporters" and "electrolytes" in the…

Although vacuum technology is essential to many aspects of modern physical and analytical chemistry, vacuum experiments are rarely the focus of undergraduate laboratories. We describe an experiment that introduces students to vacuum science and mass spectrometry. The students first assemble a vacuum system, including a mass spectrometer. While…

Quantitative reasoning is a key intellectual skill, applicable across disciplines and best taught in the context of authentic, relevant problems. Here, I describe and assess a laboratory exercise that has students calculate their "carbon footprint" and evaluate the impacts of various behavior choices on that footprint. Students gather…

Using a design-based research approach, we developed a data-rich problem (DRP) set to improve student understanding of cellular respiration at the ecosystem level. The problem tasks engage students in data analysis to develop biological explanations. Several of the tasks and their implementation are described. Quantitative results suggest that…

A floating bowling ball? No way! There is no better way to get students' attention and reinforce the need for conceptual understanding than with a discrepant event like this. Density is a central concept in chemistry and physical science from middle school to college. But often, particularly at the high school and college levels, we think students…

The main areas of difficulty experienced by those teaching and learning organic chemistry at high school and introductory university level in Ireland have been identified, and the findings support previous studies in Ireland and globally. Using these findings and insights from chemistry education research (CER), the Organic Chemistry in Action!…

The presence of geosciences in the curriculum of primary and secondary schools in Argentina has been highly dependent on educational policies that change frequently under political circumstances. Subjects related to geology, geophysics, meteorology, and astronomy make their appearance and disappear under the influence of educational initiatives…

During the fall semester of 2010, mechanical engineering students from Edison State Community College and Wright State University shared their skills and knowledge with students from the Upper Valley JVS (UVJVS) pre-engineering technology program in a highly motivating robotics activity. The activity culminated in 47 teams from regional high…

This article describes a soil-testing activity that enables students to learn some interesting and useful things about how soil behaves under varied conditions. It offers a great way to give them a practical pre-engineering experience and will show them how engineers think about construction and how local soils influence building design. The…

In an activity sequence that took place over several days, the class learned about sound and how people hear sounds. Following each activity, students engaged in whole-group sharing sessions and individual journal-writing sessions that were designed to help them see the patterns that emerged from their explorations. The activities were carefully…

Following on from taking part in the successful "Getting Practical: improving practical work in science across the primary-secondary transition" CPD project, Uplands Community College with Wadhurst and Ticehurst Primary Schools in East Sussex worked together on developing the CPD--focusing on effective practical work across the…

An initial goal of chemistry laboratory courses is almost always the "proper" use of laboratory resources including glassware and instruments. The proper use of glassware encompasses many topics, such as laboratory safety, technical proficiency, and recognition of function. However, as many chemical educators can attest, at both the K-12 and…

Anyone who plays a guitar needs a stand to hold the guitar when he or she is not playing it. A guitar is not an instrument that one can lay down or prop against the wall without risking potentially catastrophic and long-term damage. There are several options in pre-made guitar stands made for single or multiple guitars, but as an alternative that…
