【已失效】 DK Smithsonian精品, Make Lab outdoors, 寓教于乐，和孩子一起去户外疯吧

When I was a kid, I was very curious about how things worked and what things are made of. I asked myself questions like, "Why does sugar disappear when you put it in water?" "What is the air made of?" And, "Why is glass transparent?" I asked my parents and teachers those kinds of questions, too.
I’m hoping that this book will answer some questions you might have—and make you more curious, too. It's packed with lots of fun science activities and uses things you should be able to find at home or easily get hold of. They're perfectly suited to experimenting outside, in the fresh air.
