A wood-burning stove is a special machine that burns pieces of wood to create warmth. It's kind of like having a campfire inside your house! You put pieces of wood inside the stove and light it on fire. The fire creates heat that comes out of the stove and warms up the room.
The stove has a special door that closes to keep the fire inside. Some stoves even have special pipes that lead to the outside to let the smoke out.
It's important to be very careful when using a wood-burning stove because fire is dangerous. You should never touch the stove when it's on, and always make sure an adult is around to supervise. People also need to remember to always use good dry wood when making a fire, as wet wood can create a lot of smoke.
Overall, a wood-burning stove is a great way to help keep you warm on a cold day. Just make sure to be safe and smart when using it!
