The weather for the weekend is going to be very cold. We'll see temperatures as low as －15℃ in some places, and there will be a lot of wind and snow. Driving will be dangerous because of ice on the roads. So wear wear warm clothes and drive carefully.
In this book, how cold-weather affect our lives and animals. I didn't know until reading this book that shivering helps us keep warm by making hearts. I understood that's why we shiver when we feel cold.
According to this book, there are two kinds of animals: warm-blooded and cold-blooded. Cold-blooded animals, for example, are lizards and snakes. They don't need to use the food to heat their bodies.
How cool is cold!
