Here's a vocabulary list of the words used in this short Discovery Kids' Doki video. We've included all of the words used so that it could be used by beginners as well as by more advanced Spanish vocabulary learners. The list is short enough so as not to be overwhelming for either level. Interesting note: planeta and sistema, though they end in "a", are masculine nouns (as are quite a few words ending in -ma).
