Lifetimes

Teachers and parents, this book is an outstanding teaching resource, much more than the title might suggest. Beginning with: A lifetime for a mayfly is about one day, it presents 24 lifetimes such as that of an earthworm (about six years), a giant sequoia (about 2,000 years), a bacteria (well, that depends), a dinosaur (never again) and the universe (about 15 to 20 billion years). Each example comes with detailed illustrations and something to ponder, such as, for earthworms: Worms teach us that our work can be very important, even if it cannot be seen. Each plant or animal is practically a lesson plan in itself, with tell about it, think about it, and look it up challenges. Written by a retired teacher, this is a favorite book for children and teachers alike. A 48-page teachers guide based on the book is available (sold separately).
