Science
Often adding a musical connection to science makes the content less daunting and more accessible. Bringing songs into your science unit will surprise students and give them another way to be engaged while providing an opportunity for added context that will give them another way to relate to the subject matter.
Here are some of Red's songs, by topic, that can be used in this way. Have fun!
Habitat
The Human Body
The Scientific Method
Flora/Fauna/Genus
Hooray For The World (first verse)
Cotton Fields (cotton, boll weevil)
