Alternative Hertzsprung-Russell Diagrams

In this activity, Students will practise plotting Hertzsprung-Russell diagrams using a range of different, yet familiar, items. Once they have plotted their graph they will compare this with other groups.
Next they will see how a real Hertzsprung-Russell diagram is created by using the stars table to plot a true H-R diagram.

Finally, they will compare the range of items by creating a ‘master diagram’, using all the items and stars plotted. Creating an expanded H-R diagram to see how objects really compare.
