The continuing fascination of young people with celestial bodies leads them to pose challenging questions to their science teachers, such as how was the universe born? How were the stars formed? In this paper we present an extremely inexpensive but highly engaging activity to teach the basics of spectroscopy. Guided by the question "how do…

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…

This study (Note 1) investigated the beliefs about stars that students hold when they enter an undergraduate introductory astronomy course for nonscience majors. Students' preinstructional ideas were investigated through the use of several student-supplied-response (SSR) surveys, which asked students to describe their ideas about topics such as…

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…

We investigated to what extent secondary school students have insight in the apparent motion of the Sun and stars (AMoSS). We used the AMoSS test instrument, which focuses on distinctions between different aspects of the apparent motion of the Sun and stars. It consists of 12 multiple-choice questions accompanied by explanations. We administered…

The typical sound of George Lucas' laser blaster in the "Star Wars" series is well known. What does a laser blaster in "Star Wars" sound like, and why? Here we show a simple way to produce this sound by using low-cost lab material, like a spring or a Slinky. Building on the work of Crawford, who analyzed the sound of a Slinky…

This booklet accompanies a videotape covering the same material. It is intended as a guide to performing 16 science demonstrations with young children. Section titles are: "Surface Tension", "Budding Botanist", "Mystery Matter", "Young Rock Stars", "What a Gas!", "Zounds...What Sounds!", and "Brrrrr...Cool Science." Included is a section…

Discusses inquiry-oriented science instruction and experientially based programs that support newer instructional strategies. Also provides examples of six process-oriented programs (Cat Lab, Geology Search, Rocky's Boots, Tell Star, Volcanoes, What's in Your Lunch?). Level, hardware needed, publisher, and description are provided for each…

Children are very curious about the world around them. You may find them peering at tadpoles in a pond, counting ants on a log, or wondering about the stars, the sun, and the moon. I have been asked many times: Is the moon really made of cheese? Do astronauts live on the moon? Why does the moon look different every time I look up? Introducing…

To span the great distance from the solar system to the farthest clusters of galaxies in the universe, astronomers break down the distance indicators into steps. The nearest ones are measured geometrically, with what is known as parallax. Among the objects whose distances are thus directly measured are a rare type of star known as a Cepheid…

Children understand the natural world in ways that make sense to them before they learn any science in school. This column provides ideas and techniques to enhance science teaching. This month's issue helps students connect scientifically correct ideas to what makes sense to them.

The purpose of study is to investigate the fifth graders' understandings of the basic astronomy concept and, if they have, to define their misconceptions and then to determine what reason/s behind them. For this purpose, two hundred seventy fifth grade students from 6 different schools participated. Randomly selected 45 students performing under…

Stars of different masses have varying life spans, with the more massive stars "burning out" more quickly than stars of lower masses. How or what they do when they burn out also varies, depending on the mass of the star. All stars are called "main sequence stars" as they continue fusing hydrogen and staying in a state of equilibrium--a balance…

Augmented reality (AR) is a technology used on computing devices where processor-generated graphics are rendered over real objects to enhance the sensory experience in real time. In other words, what you are really seeing is augmented by the computer. Many AR games already exist for systems such as Kinect and Nintendo 3DS and mobile apps, such as…

We discuss carefully the "blackbody approximation", stressing what it is (a limit case of radiative transfer), and what it is not (the assumption that the body is perfectly absorbing, namely "black"). Furthermore, we derive the Planck spectrum without enclosing the field in a box, as is done in most textbooks. Although convenient, this trick…
