The acceleration of gravity in Earth's interior is determined by the density distribution in Earth. A remarkable result is that the acceleration is approximately constant all over the mantle, which amounts to about 84% of Earth's volume. This result can be explained by a simple two-layer model of Earth, showing that the constancy of the…

Trillion Theory (TT), a new theory, estimates the cosmic origin at one trillion years. This calculation of thousands of eons is based upon a growth factor where solar systems age-out at a max of 15 billion years, only to recycle into even larger solar systems, inside of ancient galaxies that are as old as 200 billion to 900 billion years. TT is a…

Kucukozer, Huseyin; Yurumezoglu, Kemal; Kucukozer, H. Asuman; Isildak, R. Suat – Physics Education, 2020
In this study, the tilt of the Earth's axis was measured during a lunar eclipse using a telescope based on the angle between the lunar orbit and ecliptic planes being considered as approximately zero. The presented method not only offers a practical and reliable way of measuring the axial tilt of the Earth during a lunar eclipse but also helps in…

Jelinek, Jan Amos – Education Sciences, 2021
The Earth's shape concept develops as consecutive cognitive problems (e.g., the location of people and trees on the spherical Earth) are gradually resolved. Establishing the order of problem solving may be important for the organisation of teaching situations. This study attempted to determine the sequence of problems to be resolved based on tasks…

Sagdiç, Ali; Sahin, Elvan – Journal of Science Learning, 2023
An immense body of literature on astronomy studies has provided evidence that individuals perceive the lunar phases concept as difficult. Furthermore, many studies have shown erroneous explanations or alternative conceptions of lunar phases. However, there is also a need to understand how individuals construct an explanation of the Moon's phases.…

Pili, Unofre B.; Violanda, Renante R. – Physics Education, 2020
The oscillating atmospheric CO[subscript 2] concentrations at Mauna Loa, on the island of Hawaii, Hawaii, United States of America, are Fourier transformed in order to extract the period of oscillations. Also well-known as the Keeling curve, CO[subscript 2] concentrations (in time series) at Mauna Loa oscillate in direct association with seasonal…

Seperuelo Duarte, E.; Mota, A. T.; de Carvalho, J. R.; Xavier, R. C.; Souza, P. V. S. – Physics Education, 2021
In this paper, we present a physical modeling activity whose objective is to allow students to determine the differences between a disk and a sphere using pure scientific criteria. Thereunto, we reproduce the Sun-Earth-Moon system with low-cost materials and compare the illumination effects on the Moon considering two possible shapes for it (a…

Equally as important as growing the body of human knowledge through scientific discoveries and analysis is relaying this information to the general public in a digestible manner to establish a scientifically literate society. This dissertation approaches the multifaceted issue by combining an in-depth study of brown dwarf binary atmospheres with…

Glassman, Sarah; Shepard, Elizabeth; Seymour, Ryan; Zdawczyk, Christina – Science and Children, 2020
Both children and adults struggle to explain the cause of the day/night cycle and the seasons (Schoon 1995). Early elementary students may not be developmentally ready to explain that patterns of day and night are caused by Earth's rotation on its axis, or that the seasons are caused by Earth's tilted axis as the planet revolves around the Sun.…

Soysal, Yi?lmaz – Journal of Science Learning, 2022
Science curriculums and curricular materials are essential guidelines in materializing effective science teaching. The primary goal of the current study aims to present a thematic analysis of the last three elementary and middle school science curriculums objectives released in 2013, 2017, and 2018 to determine whether they provide a base for…

Astronomy is considered by many to be a gateway science owing to its ability to inspire curiosity in everyone irrespective of age, culture, or general inclination towards science. Currently, where there is a global push to get more students engaged in Science, Technology, Engineering, and Mathematics, astronomy provides an invaluable conduit to…

Diego Pablo de la Hera; Mariano Sigman; Cecilia Ines Calero – npj Science of Learning, 2019
Throughout development, children undergo moments of abrupt conceptual transitions, often replacing intuitive knowledge with grounded scientific theories. This typically also creates a situation of social conflict, as different children may hold at the same time substantially different theories and explanations about the same phenomenon. The main…

Jansri, Sopita; Ketpichainarong, Watcharee – International Journal of Educational Methodology, 2020
Astronomy concept is regarded as one difficult topic in both teachers' and students' perspective even though it strongly appeals to the human mind. This concept requires imagination and the ability to use various skills and knowledge, for example, actual motion, relative position, and coordination of views from several points on the Earth to…

Today, individuals need a solid understanding of how earth as a system works in order to understand and develop solutions for science-based issues affecting societies on a global scale such as natural disasters, global warming or COVID-19 pandemic. Humans also deliberate space investigations, such as interplanetary travels and life in space.…

Volkwyn, Trevor Stanton; Airey, John; Gregorcic, Bor; Heijkenskjöld, Filip – Designs for Learning, 2019
In this paper we discuss the role of transduction in the teaching and learning of science. We video-filmed pairs of upper-secondary physics students working with a laboratory task designed to encourage transduction (Bezemer & Kress, 2008). The students were simply instructed to use a hand-held electronic measurement device (IOLab) to find the…
