Benchmark Question: How does our Sun rate as a star?
Focus Question: How are stars compared to each
The teacher should review
with students the ideas of measuring a star's magnitude (brightness) and
the relationship between temperature and a star’s color. The teacher should
provide students with a data table listing a minimum of twenty different
stars of different types, with their brightness and temperature.
Each student should plot
each star on a graph. There are many different ways to make such a graph,
and students should have the opportunity to set it up their own way.
Hertzsprung-Russell diagrams are commonly set up with magnitude
(brightness) on the vertical axis and temperature on the horizontal with
highest on the left. The Sun’s position on the graph compared to other
stars should be observed and discussed.
