How Old Are the Stars?

A beautifully written lesson plan delves into a beautiful topic: stellar population. Engage aspiring astronomers with activities that examine human populations and then transition onto the stars of the universe. Data and photographs for...

In this measuring star temperatures, students find the temperature of a star using Planck's curve and the Wein Displacement law. Students also find the peak wavelengths for given stars using Planck's curve.

In this Milky Way galaxy worksheet, students are given a table of distances and angles of nebulae and star clusters from the sun. Students plot each one on a piece of paper and solve 2 problems using the data.

In this galaxies, clusters and planets worksheet, students solve 5 problems including determining sunspot groups on the sun in a particular day, finding the number of individual galaxies present, determining the number of stars in...

More of a math lesson than physics or space science, high schoolers take a set of data and plot it on a log-log coordinate system. The write-up for day two was never completed, but day one, "Stars and Slopes," is complex and cohesive....

Students research the life cycle of a star. In this astronomy lesson, students work in groups to research on stage in stellar evolution and report back to the class their findings. They will discuss as a class the order of the stages and...

An excellent website detailing how a star's properties can be determined, and how these properties lead to the way a star is classified.

Students investigate the life cycle of a star through research. Once research is complete, students prepare posters and present findings to class. Flash animation is included to help students visualize life cycle of star researching.

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Finally, an astronomy lesson for the high schooler! Explorers are able to read star maps for finding objects in the night sky by determining celestial coordinates. In particular, they locate the Pleiades and read about a Navajo legend...
