 3. In the final paragraph the author uses the word ‘unimaginable’. Why have they used this word? Discuss: because it is such a long time (much longer than our lifetimes or even back as far as Henry the VIII or our family trees). It is such a long time ago that we have nothing to compare it with and cannot imagine it.

 4. What type of star is the Sun now? A yellow dwarf

5. List the different layers of the Sun from the centre to the outside. Core, radiative zone, convection zone, the photosphere, chromosphere, corona

 6. What keeps our solar system of planets orbiting the Sun? The Sun’s gravity

7. Solar means ‘relating to the Sun’. Think of two (or more) examples where we use the word ‘solar’. Any including: solar panels, solar energy, solar power, solar eclipse, solarium, solar cell, solar year

8. Will the Sun last forever? If not, why not? No. It will use all its energy eventually.

9. In the final paragraph it says that Earth will become ‘a bit like a greenhouse’. A greenhouse is warm and moist inside because of the glass that lets heat and light in and keeps it in. Our Earth is not surrounded by glass, so what will let the heat and light in and keep it in?  The Atmosphere

10. Look at the final line - where do you think humans will be by then? Open ended for discussion. There’s every possibility we may be in other solar systems or galaxies by then.
