Stars in our sky 0 Overview Using this Resource Connecting to the Curriculum Marking Student Responses Further Resources This task is about summarising information about stars to complete a table. Question 1Change answer Read this information about stars: Visibly the brightest star in our night sky is Sirius. It has a luminosity 23 times that of our Sun. Sirius is an example of a type of star called main sequence stars and has a surface temperature of 10 000°C. The type of star known as supergiants, e.g., Antares and Betelgeuse, are much cooler (under 3 000°C) but have a greater luminosity (700 times) because of their size. Another star type, the white dwarfs, e.g., Procyon B have temperatures around 15 000°C but are only 1/100 the brightness of the Sun. Complete the table to show all the above information: Read this information about stars: Visibly the brightest star in our night sky is Sirius. It has a luminosity 23 times that of our Sun.

They use this to complete a table that summarises all this information. Curriculum Links: Science capabilities The capabilities focus is brought about by the conversations you have and the questions you ask. Capability: Interpret representations Scientists represent their ideas in a variety of ways, including models, graphs, charts, diagrams and written texts. This resource provides opportunities to discuss the challenges of turning written texts into tables.
