This is a 15 slide interactive powerpoint that introduces and explains the Hertzsprung Russell Diagram.
• spectral class
The slides contain links to three different interactive activities:
• a flash animation that shows the life cycle of a star as it moves through the H-R diagram
• a diagram that allows students to predict the relative temperature and brightness of different stars on the H-R diagram
• and a link to "Star in a Box" a web app that lets students manipulate factors and see the resulting effect on luminosity, temperature, size, and lifespan.
This powerpoint has been built with unobtrusive powerpoint animations so that you can avoid the “head-down, madly copying” effect of many powerpoints. As the teacher, you can control what students are looking at and when so that there is an opportunity for rich discussion and engaged learning.
NOTE: If you find that the animations won’t run in your browser:
The issue is that the animations in this powerpoint are fairly old and run using flash. Modern browsers don’t like flash - for a lot of good reasons. However, we are at a time when many animations that are useful and certainly not malicious haven’t yet been converted to HTML5, thus necessitating some workarounds.
I created the website linked below to help if you find the animations will not run in your browser. It contains two tutorial videos for setting up your browser to run the animations.
