Magical pond that changes color with the weather
Kent Shiraishi took these photos of the Blue Pond, a beautiful body of water in Hokkaido, Japan. Blue Pond receives so much attention because of its shimmering blue hue, which changes into a lovely green in certain light. This pond owes its colors to aluminium hydroxide, a mineral which reflects blue light.
Many adults are put off when youngsters pose scientific questions. Children ask why the sun is yellow, or what a dream is, or how deep you can dig a hole, or when is the world’s birthday, or why we have toes.
Too many teachers and parents answer with irritation or ridicule, or quickly move on to something else. Why adults should pretend to omniscience before a five-year-old, I can’t for the life of me understand. What’s wrong with admitting that you don’t know? Children soon recognize that somehow this kind of question annoys many adults. A few more experiences like this, and another child has been lost to science.
There are many better responses. If we have an idea of the answer, we could try to explain. If we don’t, we could go to the encyclopedia or the library. Or we might say to the child: “I don’t know the answer. Maybe no one knows. Maybe when you grow up, you’ll be the first to find out.
