<p>Science may seem like it’s a strange thing — complicated, even a mystery. But really, science is all about finding out about nature and how things work, the reasons behind every-day things. So it’s more about questions and answers than anything. How? Where? Why?</p>
|
||
|
||
<p>It’s about making strange, mysterious, and complicated things become things we understand. There’s still lots more that we don’t understand about our world and the whole universe, but that’s where scientists come in. They are always asking questions and then finding the answers. So science isn’t really strange at all! It’s just curious people finding out about everything!</p>
