AN ABUNDANCE OF ASTRONOMY INFORMATION NO ADS NO IN-APP PURCHASES NO INTERNET CONNECTION NEEDED See what is said about our app used in classes: "My students felt like they experienced the solar system as they had read in Lucy and Stephen Hawking's book "George's Secret Key to the Universe". In that book a powerful computer can open a portal to show young George the planets. That is precisely what my classroom of children will pretend if we can manipulate Solar Walk on our large interactive screen!" — Greg Kroening, Burroughs Community School "I used this app recently when teaching Year 9 BTEC students about the composition of the Solar System. Students were engaged from the start as I had chosen to project the animation of the solar system. I was pleased and amazed by the engagement of the students throughout the lessons as this app made the lesson more accessible to all students." — Smartlearning Teacher of Science at Priority Community School Weston Super Mare. "Solar Walk gives your students a realistic look at the Solar System. Let your students take a virtual field trip to the planet of their choice to explore and report back to the class about.
