In this study, we probed high school students' understanding of Einstein's theory of gravity by implementing an approach which mainly consists of two steps: firstly, exposing students to TEs describing the Equivalence Principle; secondly, applying the analogy of parallel lines on a curved surface with the path of two falling balls in a real…

How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

This work focuses on the experimental demonstration of the hydrostatic paradox using simple tools in the form of plastic bottles and plastic syringes with a thread. For the evaluation of the results obtained the data logger Lab Quest Vernier was used. The construction of the device is presented in the first part of this paper. The second part…

The game of baseball provides an interesting laboratory for experimenting with mechanical phenomena (there are many good examples in "The Physics Teacher," available on Professor Alan Nathan's website, and discussed in "Physics of Baseball & Softball"). We have developed a lab, for an introductory-level physics course, that…

Einstein's two theories of relativity were introduced over 100 years ago. High school science students are seldom exposed to these revolutionary ideas as they are often perceived to be too difficult conceptually and mathematically. This paper brings together the two theories of relativity in a way that is logical and consistent and enables the…

Newton's laws of mechanics are a cornerstone in the development of modern science and its learning can be the very first opportunity for students to defy their common sense perceptions and replace them with a more robust world view. However, despite their fundamental importance, many studies demonstrate how difficult is the true comprehension of…

"For every action there is an equal and opposite reaction." "Except when a bug hits your car window, the car must exert more force on the bug because Newton's laws only apply in the physics classroom, right?" Students in our classrooms were able to pick out definitions as well as examples of Newton's three laws; they could…

In this note we unify two physical situations treatable with hydrostatics: an object floating on a denser fluid and an open U-shaped tube with two immiscible fluids. We begin by reviewing the problem of a partially floating uniform, rectangular prism of horizontal area "A" immersed in a denser fluid, with respective densities ?[subscript…

Though there are a multiplicity of approaches that have been used to promote Nature of Science (NOS) among school students, an approach based on exploration of a scientific discovery indigenous to the sample population, of contemporary interest, and based on a topic outside the school science syllabus seems to be lacking in the literature. This…

In this article, we present how educational resources for zoology designed by undergraduate students help to propose means of action for teaching diversity and animal evolution in basic education. We realised that activities of creation and analysis of educational resources, in the context of didactic planning, have the potential to approximate…

The discovery of and research into penicillin resistance by Sir Edward Abraham and Sir Ernst Chain can be used to teach the concept of natural selection and also multiple nature of science (NOS) objectives associated with Next Generation Science Standards, such as "scientific knowledge is based on empirical evidence" and "science is…

Our goal in this article is to provide research-based strategies for embedding Nature of Science (NOS) into science instruction at the elementary level. We thus intend to aid researchers, professional developers, and teachers in noting that not only is it important and possible to teach NOS at the elementary levels, but also that elementary…

The inclusion of engineering standards in US science education standards is potentially important because of how limited engineering education for K-12 learners is, despite the ubiquity of engineering in students' lives. However, the majority of learners experience science education throughout their compulsory schooling. If improved engineering…

While helping students develop informed views about nature of scientific inquiry (VNOSI) has been emphasised in science education, little is known regarding students' current VNOSI at a certain grade level and whether there was evidence of higher attainment of VNOSI in students in higher grades as compared to lower grades? The purpose of this…

In England, both Religious Education (RE) and science are mandatory parts of the school curriculum throughout the 5-16 age range. Nevertheless, there remain concerns that, as in many countries, students do not have a good understanding about the scope of each subject nor about how the two subjects relate. This article reports on a study that…
