Each activity includes step-by-step instructions that have been tested by educators, kids, and families. Activity materials are easily available and inexpensive—you may already have many of them in your home! AUGMENTED REALITY PLANET WALK Don’t have the time to travel several billion miles to reach Neptune? Try dropping a scale version of the solar system outside your home to start a walk that will show you planets, dwarf planets, and asteroids. At each stop, examine the space object up close using real images from NASA. Don’t forget to take a space selfie with your favorite planet! IN OR OUT GAME Quickly scan awe-inspiring images of space objects from NASA’s Earth and space observatories to decide if the objects are in or out of the solar system.

After you have mastered your solar system knowledge, challenge yourself to a new round of objects in or out of our home galaxy, the Milky Way.

Teia is an application that represents the solar system using 3D models. But, unlike the rest of the applications published in the stores, the objective of this application is to show the objects that this system is composed of by teaching perceptible and localizable curiosities on the surface of the planets. What are the rilles on the Moon? And the rupes on Mercury? Does Jupiter have a pearl necklace? Is really there a face on Mars? Why does Neptune have such an intense blue color? Learn every corner of the Solar System with this great collection of features spanning a total of over 40 pages, structured and developed by experts in the Planetary Astronomy field. The models represented have been designed taking care of the maximum possible realism, from the true color of the surface of Venus, to the structure of the ring systems. In this way, you have the feeling of visiting each planet only a few thousand kilometers away. The models represented are the following: * Mercury. * Venus. * Land. * Moon. * Mars. * Jupiter. * Saturn. * Uranus. * Neptune. Application developed by Himalaya Computing and Órbita Bianca.
