How do insects send messages to one another? How do they find things? Best for reading aloud, this book opens with a charming story about Benjamin Franklin observing ants, wondering about their behavior, and performing simple experiments to learn the answers to his questions. Combining an easy-to-follow narrative with accurate, detailed illustrations, it clearly explains the complex concept of pheromones and encourages children to observe and wonder about their own surroundings. This older book is now out of print but worth looking for at your local library.
