Students discuss the application of frames of reference to an airplane flying with a constant velocity v through the air.

Students study about deriving centripetal acceleration for motion at constant speed around a circle.

High schoolers explain that planets actually orbit the center of gravity of the solar system, and that distant planets may be detected by motions of their central star around the centers of gravity of their planetary systems.

Students trace the beginning of the heliocentric theory of the solar system--the idea that the solar system revolves around the Sun--to an observation by the Greek astronomer Aristarchus, which convinced him that the Sun was much bigger...

Students examine total eclipses of the Sun and their limited regions of totality. They explain that this limited view occurs because the Moon is close enough to us for different points on Earth to view it differently.

Students discover how Aristarchus, a Greek astronomer around 230 BC, used a simple observation of the eclipse of the Moon, plus clever reasoning, to deduce the distance of the Moon. They practice the same calculation technique.

Students discover how astronomers used the diameter of the Earth's orbit around the Sun as a baseline for estimating the distance of some stars, and the meaning of "Parsec" and "light year."

Learners explain how Hipparchus, around 130 BC, used a shift in the predicted location of a lunar eclipse to detect a slight shift in the path of the Sun around the sky. They examine the elliptical orbit in which the Earth travels around...

Students explore the discovery of pulsar stars, and the characteristics of pulsar stars. Theories and ideas behind black holes are discussed. The issues of women's historical role in science are also touched on.

Ninth graders examine how dark surfaces absorb more light than light surfaces. They perform an experiment that compares various surfaces abilities to absorb heat, then record and analyze the results.

Young scholars parcticipate in a modeling activity that simulates the cyclical role of experimental and theoretical science. Initially, students measure the mass of popcorn. They also record predictions of the mass of the kernels after...

Learners explore universe, and examine how big it really is and how scientists measure the distances or sizes of things by estimating sizes of different objects and reading and writing numbers in scientific notations.

Students investigate the supposed traveling path of a meteorite. They use sound in order to triangulate the path. The results of the experiment are written on a map to display the path of the meteorite. The culminating activity is when...

Learners explore constellations. They read trade books about constellations and write notes including their locations, origins, and names. They research and report on one constellation in the Northern Hemisphere and share their report...

Pupils investigate the uses and purpose of the Hubble telescope. They create a model of the telescope and conduct research about the history behind the invention of it. Students use the information in order to create a context for the...

Students investigate the concept of star mapping and how it is used in space navigation. They conduct various activities to see the effect of mapping. Also the teacher uses models and demonstrations in order to communicate the main...

Students engage in a lesson about the moon and three different constellations. They conduct research using a variety of resources. The teacher leads the class with demonstrations and discussion groups. The research is also guided using...

Students investigate the universe through the eyes of the Hubble space telescope. They conduct research from looking at the universe that is simulated with a digital projector. The images are projected onto the wall in a simulation of...

Sixth graders are introduced to the moon and its phases. Individually, they draw a sketch of each phase of the moon and read a short article about Galileo. To end the lesson, they examine the difference between refracting and...

Do you have what it takes to go on a space mission to the Red Planet? Think you can handle it? Take this quiz to find out!

Site provides information on the Earth's atmosphere as well as offers additional information about Earth.

Site describes multiple resources for the beginner amateur radio astronomer. Great general information for beginners on basic radio physics and on the fundamentals of radio telescopes. Nice set of links to other useful sites.

This resource presents information on the Harvard-Smithsonian Center for Astrophysics. There are links to research, events, facilities, press releases, etc.

Karl Jansky discovered extraterrestrial radio waves while investigating possible sources of interference in shortwave radio communications across the Atlantic for Bell Laboratories, and is often known as the father of radio astronomy....
