Astronaut:  Dr. Mae Jemison The 100 Year Starship.

Astronomers have been working for decades to locate and identify all of the planets they can.

There are eight planets in our solar system, and there could be billions more throughout space. Readers will discover what methods these scientists use, how new technology has helped them see further than ever, and why some scientists think that faraway planets could be home to life forms unlike anything on Earth.

Astronaut:  Dr. Mae Jemison The 100 Year Starship.

What would we find if we made it all the way to another star's solar system?

So far, our travels into outer space have been limited to the planets and moons surrounding the sun in our own solar system. Today's astronomers are planning a mission to explore further reaches of space than humans have ever reached. Readers (Grades 3-5) will discover how these bold scientists are working to build faster spaceships and overcome the obstacles that make it difficult for humans to survive in outer space.

For hundreds of years, curious scientists have been studying these planets and moons and learning more about them. Readers will learn about the many methods astronomers have used to study our solar system, from the basic telescopes of the 17th century to today's advanced space probes.

Dr. Mae Jemison and 100 Year Starship.

Our solar system is made up of eight planets orbiting around the star we call the sun, as well as the various moons that orbit the planets.

For hundreds of years, curious scientists have been studying these planets and moons and learning more about them. Readers will learn about the many methods astronomers have used to study our solar system, from the basic telescopes of the 17th century to today's advanced space probes.

Astronaut:  Dr. Mae Jemison The 100 Year Starship.

This book explores how the sun was formed, what it is made of, and how its energy travels to Earth and the other planets of the solar system.

The sun provides us with the light and energy we need to survive.

It also serves as the center of our solar system, with its gravitational pull keeping the planets in orbit. But what exactly is the sun? Readers will explore how the sun was formed, what it is made of, and how its energy travels to Earth and the other planets of the solar system.

A True Book-Physical Science

Whether you're an aspiring inventor or an everyday science buff, you've probably created your own experiments to uncover the truth about the forces of physical science. Now you can delve deeper into the topics of electricity, motion, gravity, and more with these titles that are perfect for the budding scientist in you.

This book describes what gravity is, the history of its study, and its effects.

Why was Galileo put in jail for his writings about gravity?

The Pope was angered by Galileo’s work proving that Earth was not the center of the universe.

inside you’ll find:

* Why gravity keeps us from floating into outer space;

* A timeline, photos - and how gravity works on other planets;

* Surprising TRUE facts that will shock and amaze you!

This book briefly describes the science behind friction, and what its effects are.

Need a good way to introduce physical science topics to your children? This series of books will not only do just that, but also spark some curiosity to further learning. Your children learn about inventions, inventors, and how different forces (like friction or gravity) are used in everyday life. Plenty of fun photographs and facts are packed into these small books.

In order to maintain careful control over the safety and accuracy of their experiments, scientists often work in laboratories. Labs give scientists the space and equipment they need to make their greatest discoveries. Readers will tour some of the world's most incredible laboratories, from the ocean research vessel that can flip from a vertical position to a horizontal one to the massive International Space Station.
