What if the sun stopped shining?

Quick question: How long would it take you to notice if the SUN STOPPED WORKING??? 3 seconds? 30 seconds? 2 minutes? 8 minutes? 

If you said 8 minutes – you’re right! To be exact, it would take 8 minutes & 20 seconds before you noticed sunlight was no longer reaching the Earth. Thankfully, that won’t be happening anytime soon (at least 7 or 8 billion years), which leaves you and your child plenty of time to learn a whole lot of cool things about the closest star to the Earth… the Sun!
