A nice song from Olivia Holt, a song written specifically for the Disneynature documentary "Bears". In an interview she said that the song really captures the “struggles and heart” of the film. There are several exercises: choose the right word, match the lines, fill the gaps, find extra words and correct mistakes, fill the gaps with antonyms and complete the missing vowels. It is also useful to introduce or to review Future Simple. I hope you like it!
P.S. If you are interested in the topic, on the official page there are a lot of activities related with bears: http://nature.disney.com/bears/educators-guide
