Chemistry for Kids: Why is Milk White?

1 Comment

Many of us probably learned about chemistry in high school from a textbook (and probably promptly forgot most of it). Isn’t it wonderful we now have popular chemistry books for kids, like Why Is Milk White?: & 200 Other Curious Chemistry Questions by Alexa Coelho and Simon Quellen Field?


In this unique book, 11-year-old Alexa Coelho came up with the questions and then science writer Simon Field answered them. Amongst the questions and answers, Field also has instructions for some hands-on science investigations.

The answers to some of the questions might surprise you. When Coelho asks, “Can you change lead into gold?” it turns out that it is possible by bombarding mercury with gamma rays, and the process occurs naturally in stars. Take that, alchemists!

The big advantage of the question and answer format in Why is Milk White? is that readers can skim through and read only the questions that interest them, a plus for reluctant readers. Middle grade readers who are serious science fans, however, will want to read it cover to cover.
