"Firefly Light Up the Sky" is a general music lesson with vocal exploration of high/low sounds, composition, and (if you wish) sound effects paired with the book "Firefly Light Up the Sky".
Book is not included but can be found on amazon.com with sound effect flashlight.
This lesson was used for the K-2 music classroom. It could plausibly be used for 3rd grade as well for some fun, and would work for Pre-K too.
Prep time: Outside of reading instructions and obtaining/reading the picture book before class, this should take very little prep-time.
Students loved this activity and constantly asked to come back to it!
