Star Evolution – 8 – Stages of Stellar Evolution

This is part 8 of an 8 part session series on Star Evolution. Find Part 1 here.

By watching a presentation students get the information about stages of stellar evolution. Then using the computer animation students explore the changes of stellar parameters during different stages of stellar evolution. Finally they draw a schematic diagram of stellar evolution.

Classifying the Universe

This is a great activity to do prior to a visit to an observatory.

In this activity, students will learn different ways of roughly separating the features of observable structures in the universe and will gain the tools needed for identifying what kinds of objects they can observe through telescopes when visiting the observatory.

Discovering Exoplanets with the Transit Method

Exoplanets are too small and far away to see directly, even with the most powerful telescopes. So how can astronomers detect them? When an exoplanet passes in front of its star it blocks some of the star’s light. For a short time, the star’s brightness decreases. So, if astronomers detect that a star’s brightness decreases and then increases again, they can deduce that there is a planet orbiting the star.

In this activity students will investigate how scientists use a transit to detect exoplanets.
