The purpose of this article is to provide teachers of science scientific definitions and illustrations to facilitate the teaching of cosmology. Secondary school science teachers can use the illustrations and their citations to pose questions to their students and to guide their students to accessible digital sites where the students can explore…

The Sun does not return to the same position in the sky every 24 hours. At local noon, for example, the Sun will appear higher in the sky as we move from winter to summer solstice. In addition, and perhaps more surprisingly, solar days (the roughly 24 hours between subsequent local noons) vary in length, causing the Sun to be east or west of its…

Investigating stars can be difficult. The five-day unit presented in this article is designed for fifth graders to work toward Next Generation Science Standard (NGSS) performance expectation 5-ESS1-1, with each lesson lasting about 30 minutes. Students investigate the relationship between the brightness of light and distance, apply their…

This article describes how kindergarten scientists at Caldwell Heights Elementary School in Round Rock, Texas created what they named a "Light Circle" using their classroom's south-facing window, its windowsill, and a small round mirror. The tilt of the Earth and the latitude of one's location combine to determine if the Sun ever shines…

Children can see the Moon with the naked eye and often are curious about the Moon and other objects in the sky, like the Sun and the stars. However, there is sometimes disagreement in early childhood about whether studying space is appropriate for young children. This activities described in this article engaged children who had different learning…

Given the great interest that black holes arouse among non-specialists, it is important to analyse misconceptions related to them. According to the author, the most common misconceptions are that: (1) black holes are formed from stellar collapse; (2) they are very massive; (3) they are very dense; (4) their gravity absorbs everything; and (5) they…

Virtual reality (VR) technologies have the potential to transform astronomy education practices profoundly: new forms of visual representations, perceptual engagement and embodied participation promise authentic learning experiences in formal and informal learning spaces. While a growing body of research studies the educational needs and…

This paper describes a method to demonstrate that the plane of the lunar orbit around Earth and the plane of the ecliptic (the plane of Earth's orbit around the Sun) are inclined with respect to each other, and to present a method for measuring the angle of the inclination. The angle between the diameter of the Moon's orbit when the Moon passes…

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…

Many introductory astronomy courses include concepts related to basic stellar properties. In general, these are concepts that originate from the human perception of starlight. This observational aspect is not easy to incorporate in the classroom. We explore if these concepts could be developed using the built-in data in a planetarium software.…

In this, the first installment in a series, I present a list of approximately 10[superscript 2] questions that can be addressed in an introductory astronomy course using ubiquitous farmer's almanacs. Some of these questions take the reader into the world of astrology and perhaps other pseudosciences, but that is okay with me because at one time…

Models are at the heart of any physics discipline, and in recent decades physics education has shifted heavily toward teaching students how to think using models. Involving students in an investigation of a real phenomenon through measurements and the applications of models is an ideal learning experience for a physics student and is the aim of…

At the Center for Integrated Access Networks (CIAN), an Engineering Research Center funded from 2008-2018 by the National Science Foundation, the education department worked to develop new and innovative digital resources to engage students in learning science content. One resource created, the CIAN Comic Book, focuses on educating students about…

The observation that the shadows of objects change during the course of the day and also for a fixed time during a year led curious minds to realize that the Sun could be used as a timekeeper. However, the daily motion of the Sun has some subtleties, for example, with regards to the precise time at which it crosses the meridian near noon. When the…

Space is a key area of science that is often taught in year 5 (ages 9-10) in English schools and related to this is gravitational force. Almost without exception children enjoy learning about the solar system and beyond. This article introduces a series of activities for children to explore the formation of impact craters in the solar system. The…
