Below are ideas for extending this topic beyond the Exploration and Activity you just completed.

• Lesson Assessment and Answer Key
• Activity: Eyes on Exoplanets Explore thousands of planets outside our solar system.
• Activity: Exoplanet Travel Bureau Stand on the surface and explore other planets.
• Readings: Read more about the Sun and the search for habitable planets.
• Videos: Mystery Science Mini-Lesson extensions.

NASA’s “Eyes on Exoplanets” will digitally fly you to any star or planet outside our solar system. You can visit over 1,000 planets that scientists have discovered to orbit distant stars. Find out how long it would take you to get to each place if you were to travel by car, jet plane, bullet train, or starship. Turn on the “habitable zone” display to show the region around each star that could potentially support life. Requires a one-time download of the app onto a desktop computer.

With NASA’s Exoplanet Travel Bureau, you can imagine what it’s like to stand on the surface of far-away planets. Visit their website, and with the click of a button, you can pretend you’re standing on the surface of planets outside our solar system. On TRAPPIST-1d you can see look up at the sky and see six other planets. You can also see what happens when you stand on a planet that has two stars (instead of one) in the solar system.

These readings from Newsela are free with registration. They can be adjusted for reading level. Writing prompts and quiz questions are available for most readings.
