If you don't have to run your heater all year, you're probably familiar with the smell that accompanies turning it on again in the fall. But what causes that smell? Is something burning? What does it mean for something to burn, anyway? Does there have to be fire for something to burn? Join Cheryl as she learns answers to these and more questions this week. It's never too late to learn about the world around you. &nbsp;
This is a listener question. &nbsp;
