Future Honor Roll Student! Children's Encyclopedia for Elementary School Students

Dear friend!
.Do you know what a black hole is? When did the first person appear on our planet and who invented the television? Why do you always fall to the ground, while astronauts "fly" inside the space station? Which bird can fly backwards, and why do lizards have tongues? You will find the answers to these and many other questions in our illustrated encyclopedia!
.From this book, you will learn when the first airplane flew, where the "ghost" monkeys live, and how many teeth a shark has. You will see the largest flower and the smallest bird on Earth, read about an ancient reptile that lives in our time, and about a modern domestic robot.
.Onward, to new knowledge and discoveries!
