Children have an amazing ability to casually ask difficult questions. If you've ever been asked that perennial question of “why?” by a child, you'll likely know how hard it can be to answer – whether how to explain something simply or because in truth you've forgotten (or never knew the answer 🤫). When the grown-ups can’t answer them, they submit these questions to the experts at The Conversation.

While many adults were seeking facts on the pandemic, children were still wondering about life’s greatest mysteries: Why don’t things move around if the Earth is spinning all the time?🌍 How much does a cloud weigh?☁️ How do you know when a volcano will erupt?🌋 How did plants and trees survive when the dinosaurs were wiped out?🦕

Of course, there were some COVID questions – profound ones, such as whether the pandemic will distract us enough to stop having wars; and ones clearly aimed at convincing parents to get a puppy for Christmas, like whether your pet could protect you from the virus.🐶

And they were still curious about kid stuff too, such as how voices work, whether witches and wizards are real (we wish!) and why there are so many dangerous animals in Australia.🪱

Below is a round up of some of our best Curious Kids pieces from 2020. They may be submitted by pip-squeeks, but there’s plenty of insight in there for the grown-ups too.
