Greenwood, Margaret Stautberg – Physics Teacher, 2022
From my home on the west bank of the Columbia River in Richland, Washington (46.3°N latitude), I have an unobstructed view of the sunrise along the east bank during an entire year. As a retirement project after a career of teaching and research in physics, I decided to take photographs of the sunrise for a year and, and at the same time, carry out…

Simon F. Kraus – Science & Education, 2024
Observation is widely regarded as a fundamental way of studying nature. However, due to its complexity, proposing a comprehensive characterization is challenging. Observation is a method of studying nature that can be divided into several dimensions. Each of these dimensions can be presented as a pair of terms, which are elaborated in this paper…

Levenson, Barton Paul – Physics Education, 2022
An internet poster recently floated the idea that friction with a recently denser interstellar medium causes global warming. Despite its superficially ridiculous nature, refuting this proposition is an interesting quantitative exercise.

Fairhurst, Ciaran; Tyler, Paul – Primary Science, 2022
Space telescopes are some of the most precise and complicated machines ever built. Not only must they survive the harshness of space travel, but they also need to be incredibly accurate: misalignments by fractions of a millimetre can have huge effects on the quality of the images they capture. In 1990, the Hubble Space Telescope became the first…

Salimpour, Saeed; Fitzgerald, Michael T. – Science & Education, 2022
This study explored over 200 journals and a content-focussed research repository to investigate the occurrence of research on the Big Questions in the field of astronomy education research (AER), focussing on Cosmology and Religion. Using both qualitative and quantitative techniques, 151 articles were selected and analysed. Our results reveal that…

Farney, Michael Noble – Physics Teacher, 2022
Physics teachers are sometimes asked to teach an astronomy course for non-majors. One can't make that class dance and sing without the starry night, but on a brightly lit campus viewing deep sky objects may seem impossible. Hence instructors often opt for planetarium shows. However: 1) Planetariums aren't the real thing. 2) People living in large…

Emslie, A. Gordon; Oliver, Travis P. – Physics Education, 2022
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…

D. K. Keblbeck; K. Piatek-Jimenez; C. Medina Medina – Physical Review Physics Education Research, 2024
Historically, physics has been a predominantly male field, with previous literature showing that there is little diversity among U.S. physics students at the undergraduate and graduate levels or among physicists within the work force. Recent research indicates that the lack of diversity in physics is partially due to an unwelcoming climate within…

Kristel Izquierdo – ProQuest LLC, 2021
Knowledge about the interior density distribution of a planetary body can constrain geophysical processes and reveal information about the origin and evolution of the body. Properties of this interior distribution can be inferred by analyzing gravity acceleration data sampled by orbiting satellites. Usually, the gravity data is complemented with…

Undergraduate physics and astronomy students are expected to engage with scientific literature as they begin their research careers, yet reading comprehension skills are rarely explicitly taught in major courses. We seek to determine the efficacy of a reading assignment designed to improve undergraduate astronomy (or related) majors' perceived…

Herman, Thaddeus – Physics Teacher, 2022
Even though many physics teachers take their students on a calculation adventure through circular motion and Newton's universal law of gravity to determine Earth's velocity, most of us leave it at that. We present the final result and say, "Look, Earth is moving around the Sun at about 107,000 km/hr (66,000 mph), yet we can't feel the motion…

White, Douglas W. – Physics Teacher, 2022
Laboratory astrophysics and astrochemistry are emerging fields highlighting the importance of laboratory simulations and experiments to benefit remote observations. In particular, ice mixtures found in the outer solar system may offer insight into the early evolution of organic molecules. H[subscript 2]O-ice mixtures containing other species such…

Amato, Joseph C. – Physics Teacher, 2022
The Double Asteroid Redirection Test (DART) is a National Aeronautics and Space Administration--European Space Agency collaborative mission to test the feasibility of defending Earth from a catastrophic asteroid impact by using a spacecraft to deflect the asteroid away from the planet. Launched on Nov. 23, 2021, the DART spacecraft will intercept…

Simionato, Silvia – Physics Teacher, 2021
The concept of redshift is very often used in teaching physics and astronomy, as well as in science public outreach. Redshift is an interesting topic, used to describe many physical processes such as the Doppler effect or the expansion of the universe. Nevertheless, there are unfortunately also misconceptions about redshift. When facing the…

Inbanathan, S. S. R.; Moorthy, K.; S., Ashok Kumar – Physics Teacher, 2021
The falling temperature of the photosphere with height is responsible for the effect known as limb darkening. The Sun is not equally bright all over the disc. When we observe the Sun towards the limbs, it appears to get darker. Light from the photosphere travels through an absorptive medium. Therefore, one can see only so far into the photosphere.…
