A digital version of the Year 9 P1.15 Life cycles of stars lesson.

This resource contains a 21-slide theory lesson and a Kahoot Quiz as a plenary.

Slide number 1 is an introductory slide explaining the lessons learning objectives.
Slides number 2 defines Stellar Nebulae as clouds of dust and gas where stars are ‘born’.
Slide number 3 explains how Stellar Nebulae collapse due to gravity to form a protostar.
Slide 4 looks at Main sequence stars and explains how our sun is a main sequence star.
Slide 5 & 6 look at what happens when the core of a main sequence star runs out of hydrogen and then helium to become less bright; forming a red giant.
Slide 7 shows that when a red giant finally collapses then its outer layers shed off and the remains are called a white dwarf.
Slide 8 shows that the outer layers of the red giant that drift off into space become planetary nebulae.
Slide 9 looks at the different life-cycle of massive stars and begins by comparing the relative sizes of some known stars.
Slide 10 and 11 show how massive stars become red super-giants – using Betelgeuse in the constellation of Orion as an example.
Slide 12 looks at what happens when Red Super-giant stars start to die.
Slide 13-15 looks at Supernova’s - the death of Red Super-giant stars.
Slide 16 and 17 look at the two possible outcomes post supernova. Giant stars become either a Neutron star or a Black hole (depending on the size of the giant star).
Slide 18 and 19 are much needed summaries of both Star life-cycles.
Slide 20 is the book-work reference with two hyperlinked you tube videos of Stars life cycles.
Slide 21 contains the hyperlink to a Kahoot Quiz based upon this lesson
Slide 22 contains the image credits.
