Praseodymium - Periodic Table of Videos
Let’s Begin…
The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about praseodymium, an element used to filter harmful light. Praseodymium has even helped slow light's speed down to a mere 300 meters per second!
Create and share a new lesson based on this one.
Watch the video and finish the Think section to complete the lesson.
