The five papers published by Hodgkin and Huxley in 1952 are seminal works in the field of physiology, earning their authors the Nobel Prize in 1963 and ushering in the era of membrane biophysics. The papers present a considerable challenge to the novice student, but this has been partly allayed by recent publications that have updated the…

By building a schlieren optical system, the visualization of a 40 KHz sound wave is realized. By using the schlieren system, the demonstration of acoustic reflection, interference and diffraction can be easily realized. At the same time, the visual acoustic field provides another simple way for the measurement of sound velocity. In this paper, the…

Undergraduate organic chemistry students, as they study conformational analysis and stereochemistry, frequently have trouble manipulating three-dimensional structures on a two-dimensional page or screen. The inability to accurately convert three-dimensional bond-line representations into Fischer projections is one example of this. While some…

Students in a typical instrumental analysis course may learn more than 30 analytical techniques. There are more than 150 components associated with the instrumentation that they learn. To help students organize this large amount of information, we classified these components into four categories: sources, samples, discriminators, and detectors. In…

Philosophy is concerned with fundamental questions about knowledge, truth, reality, experience, justice and what is right and wrong. In this article, the authors discuss how philosophy and science can be taught together in the primary classroom.

These days, smartphones are popular commodities among students in high school and college. Students carry their devices all the time, so why not use such a popular electronic device to measure physical quantities such as "g" in physics labs? In this work, we report a "multiple tasking" method, a measurement technique that we…

This article outlines Primary Science for All resources and ideas designed to raise engagement in science for pupils with special educational needs. The aims of the Primary Science for All project were to: (1) make science more accessible to primary school pupils with invisible special needs and to enhance their progress in science; and (2)…

To span the great distance from the solar system to the farthest clusters of galaxies in the universe, astronomers break down the distance indicators into steps. The nearest ones are measured geometrically, with what is known as parallax. Among the objects whose distances are thus directly measured are a rare type of star known as a Cepheid…

The topic 'Animals including humans' runs through the primary science National Curriculum in England (DfE, 2013). Ideally, topics such as inheritance will lead onto adaptation, natural selection and evolution across key stages 1 to 2 (ages 5-11). This article provides nine engaging activities to support the teaching of adaptation and improve…

Instruction in academic core content provides students with moderate to severe disabilities a full educational opportunity that promotes current and future options in the community and can complement acquisition of daily living skills. However, high school teachers face many challenges in balancing instructional priorities given the mission to…

We developed a simple device to teach the concept of pH to visually impaired people through an experimental approach. An interface between a glass electrode and an open-source electronics platform based on easy-to-use hardware and software (Arduino Uno) was designed using an operational amplifier of ultralow input current. A headphone connected to…

Scientists must interpret and produce visuals in their work. Scientists also use visual information to communicate their findings to the general public. Visual representations are used in science because of the abstract nature of scientific information as many concepts are unable to be seen with the naked eye. The current educational climate…

As part of the "Next Generation Science Standards" (K-LS1-1), students are expected to develop an understanding of what living things need in order to live and grow. The lessons provided in this article help students understand the difference between living and nonliving things, and help them acquire important background knowledge to…

In this article, Julian Grant, a Prep VI class teacher at Bridgewater School, Worsley, Manchester, explores the cross-curricular nature of language in scientific recording and how children can waken an audible science world with words. The ideas that came from what started as an applied vocabulary exercise demonstrated just how many…

Everyone needs strong observational skills to solve challenging problems and make informed decisions. However, many students expect to find exact answers to their questions by using the internet and do not understand the role of uncertainty, especially in decision making and scientific research. Humans and other animals choose among many options…
