Learning Objectives
Educational Standards
Each TeachEngineering lesson or activity is correlated to one or more K-12 science,  technology, engineering or math (STEM) educational standards.
All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN) ,  a project of D2L (www.achievementstandards.org).
In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics;  within type by subtype, then by grade, etc .

Content: In fact, one way a planet can be detected is by observing if a star wobbles, which might be due to the gravitational pull of an orbiting planet. Spectroscopes and telescopes are two tools that help us find other planets and galaxies from Earth or on board spacecraft. Do you think any of these other planets outside our solar systems could support life like we know it on Earth? We have not found any yet. For a planet to support life like on Earth, it would need to be very similar to Earth. It would need to be solid for humans to stand on. It would also need to be the right distance from its sun to have the right temperatures and pressure to support water for humans to drink! Engineers and scientists do not let great distances stop them from exploring the universe, though. In fact, engineers have used the knowledge of the universe to design spacecraft to travel far distances away from our solar system. Voyager 1 is the fist human-made spacecraft designed to leave our solar system to explore the Milky Way.
