The educational books set by Levenhuk includes two colorful books created specifically for children of school age.
Invisible World Knowledge Book This encyclopedia will introduce a young reader to the basics of biology and microscopic observations. A child will learn what a microscope is and how to use it; and how bacteria, fungi and sponges look under the microscope’s objective. The book will be an excellent guide to the microworld and biology.
Space Non-Emptiness Knowledge Book This colorful book will introduce the young reader to outer space and astronomy. The book tells the child about the structure of the Solar system, the objects of outer space; and teaches how to observe the night sky through a telescope. The encyclopedia is perfect for independent study of the basics of astronomy.
Both books are aimed at children over 6 years old and contain a lot of practical information. The pages of the books contain instructions for conducting scientific experiments at home.
