This is a fun and informative series of books, written and illustrated by Robert E. Wells, that helps introduce some basic science concepts to children. They are geared mainly toward pre-kindergarten through third grade, but they can be enjoyed by any age.
Our favorite of the ones we've read is How Do You Lift a Lion? which introduces simple machines such as the lever, wheel, and pulley. The illustrations are clear and clever, and show how a lion could be lifted if you had enough leverage. We are also shown how to pull a panda on a pallet, and how it could be possible to deliver a big basket of bananas to a baboon birthday party using pulleys.
Is a Blue Whale the Biggest Thing There Is? is another entry in the series. Here we are shown progressively bigger things from whales to earth to stars, until we get to the size (or what is known of it) of the whole universe! You definitely feel small after reading this book, and the illlustrations are very amusing at times (such as a crate of "sun-sized oranges" to demonstrate how our sun compares in size to a red supergiant).
What's Smaller Than a Pygmy Shrew? covers the same idea, but getting progressively smaller, from a shrew to a ladybug to protozoa and protons. This one may be harder to wrap one's mind around, but does a great job of helping us to visualize the idea that there is a whole kingdom of living organisms that are too small for our eyes to see.
We also enjoy What's Faster Than a Speeding Cheetah? which shows us many things that are faster than a cheetah, such as a peregrine falcon, a rocket, and a meteoroid.
These are the only titles we've read so far, but there are several others that sound just as interesting, such as Why Do Elephants Need the Sun?
