This study aims to examine preschool teachers' earth and space science practices and the expected achievements of children in these practices. The research was conducted with a phenomenological pattern. Participants of the study consisted of 28 preschool teachers working in public schools and determined by the criterion sampling method, one of the…

The epistemic components of science are included in instruction through the three-dimensional learning of the Next Generation Science Standards (NGSS). Students use the Science & Engineering Practices to engage the Disciplinary Core Ideas through the perspective of the Crosscutting Concepts. The NGSS focus on the epistemic aspects that all…

The paper describes an upper-division university course in Mars literature taught online since Fall 2013. The course readings comprise six novels relating to Mars. Authors include H.G. Wells, Edgar Rice Burroughs, Ray Bradbury, Phillip K. Dick, Greg Bear, and Kim Stanley Robinson. After an introduction, sections of the paper discuss course…

This paper highlights the design process and implementation for an "all majors" undergraduate course that allows students a chance to reconnect with the natural world. During this course students explore a wide range of biological and physical science based topics that seek to highlight human intervention and our impacts on the planet.…

We consider the operation of the hypothetical mechanical vehicle driven by an engine powered by small rockets introduced by P D Hanstead in the inaugural volume of this journal. Hanstead arrived at three contradictory conclusions regarding the change in velocity should some of the rockets malfunction at a particular time. This thought experiment…

Data from the Kepler satellite were analysed using the Mikulski Archive for Space Telescopes database. With the participation of 53 students, we determined the parameters of the HAT-P-7b (Kepler-2) exoplanet system (transit duration, planet-to-star radius ratio, orbital period, semi-major axis and star mass). We used approaches that are easy to…

The aim of this study is to comparatively investigate the effects of hands-on models (HMs) and computer simulations (CSs) on teaching the phases and eclipses of the Moon. In this study, two different HMs were developed, and three different CSs were used. The research work group consisted of 100 pre-service science teachers. A quasi-experimental…

A great deal has been written about the huge benefits to children of learning through the context of stories. Some scientific concepts can be difficult for children to understand if they cannot see or experience them. Stories help bring the concepts to life, making them more meaningful, increasing engagement and often providing a more fun…

Similar to how stealth materials were developed to reduce the radar wave energy returning from an aircraft, here we explore a low-cost laboratory demonstration that uses similar principles to prevent detection of an object by an ultrasonic sensor. This demonstration setup can be used as a starting point to encourage students to explore the surface…

Most likely a large number of students have heard of the Northern Lights (Aurora Borealis), and know that they are a phenomenon in the sky. Although they may not have seen the Northern Lights, most have probably seen other phenomena in the sky, such as a rainbow, shooting star, or super moon. These experiences provide an opportunity for students…

A discrete model of invasion by subversive alien bodysnatchers is constructed and analysed numerically as a proposed undergraduate project. Several extensions of the model are demonstrated, including a spatial system of ten planets arranged on a one-dimensional lattice, and we discuss some of the practical considerations that arise when…

This paper describes the results of a survey administered to members of the American Association of Physics Teachers and the National Earth Science Teachers Association to measure the nature and frequency of the integration of Earth and space science (E&SS) concepts into physics courses, as well as the need and interest of physics teachers to…

Space exploration is intrinsically interesting to young learners. Children gaze at the stars and marvel at what it might be like to live "out there!" With the July 2020 launch of the Mars 2020 Perseverance Rover mission, and its landing in 2021, there is no better time to capitalize on engineering and science in the news. This mission is…

A new curriculum is set for implementation in Wales from September 2022. Preparation for change is already underway in Gwaunmeisgyn Primary School in South Wales. Various development teams are preparing for the new curriculum, including the three teachers in the science and technology team. The team met to plan and design a bespoke pilot project…

The sensation of weightlessness is common to an astronaut in a spaceship orbiting Earth and to a person aboard a freely falling elevator. This paper presents a detailed treatment of this commonality by showing that a spaceship orbiting Earth is in permanent free fall toward the planet, appropriate for use in the introductory classroom.
