We study the variation of the apparent weight of an object with height above the surface of a planet with a (buoyant) atmosphere. Interestingly, this variation depends on two competing factors--the reduced gravitational acceleration (which acts to reduce the weight with increasing height) and the reduced buoyancy force in the progressively less…

Besides being a country with high inequality, Brazil faces an alarming sociohistorical moment in which the coronavirus disease 2019 (COVID-19) pandemic is exacerbating a disastrous political situation that promotes polarization and social division. The context of this situation is described here through a critical lens, as a justification for…

Amy Strachan and Jemima Davey's new book, "Saving the Planet One Science Lesson at a Time" (Strachan and Davey, 2022) uses the UN Sustainable Development Goals (the blueprint to achieve a better and more sustainable future for all; United Nations, 2015) as a framework to show that science knowledge and skills can support the achievement…

This guide includes 8 elementary school level lessons, inspired by topics from "Ocean Odyssey," a film for IMAX and other Giant Screen theaters. Host-narrated by oceanographer Sylvia Earle, "Ocean Odyssey" is an immersive film following a mother and calf humpback whale on their migration from the tropics to Antarctica.…

To combat environmental apathy, the authors seek to help students develop environmental knowledge, ethics, and "critical-thinking skills that will prepare them to evaluate issues and make informed decisions regarding stewardship of the planet". This article describes scientific, place-based investigations of local species and their…

The COVID-19 Pandemic impacted world society in many ways. The virus rode our interconnected transit systems and exploited a globally connected world where a person can traverse the planet within a day; far shorter a time than the incubation period. The virus challenged our assumptions on communicability of disease and transmission vectors. It…

Explaining phenomena associated with a system involves describing a system's structure and articulating the process through which the system's structure changes over time. This paper defines geo-sequential reasoning in the context of plate tectonics and uses it to analyse how students explain the geological processes that occur along convergent…

In the last decades, agroecological and permacultural initiatives and organizations have grown. These initiatives attend to notions of food sovereignty and alternative models of agricultural production. The confluence of different actors and social initiatives through which experiences and knowledge of cultivating food are shared, and new ones are…

Research in astronomy education has uncovered that many learners possess limited and fragmented understanding of stars. The corresponding misconceptions manifest in various areas such as star formation, size, the relationship between stars and planets, and their position in space and have been shown to persist across different age groups and…

Burlington Junior School in the East Riding of Yorkshire decided to highlight some excellent role models to its pupils during British Science Week 2021, who were not the stereotypical male, white, old or dead scientist. The intention was to make learning more relevant, more accessible and therefore more engaging and informative. It was hoped that…

When students think of evolution, they might imagine T. rex, or perhaps an abiotic scene of sizzling electrical storms and harsh reducing atmospheres, an Earth that looks like a lunar landscape. Natural selection automatically elicits responses that include "survival of the fittest," and "descent with modification," and with…
