This is a cute song I sing with my class to help them remember the differences between a carnivore, herbivore, and omnivore. As an extension activity, I have the students take a classic tune/song and rewrite the lyrics using their knowledge of science.
The "Atom's Family" (to the tune of the Addam's Family song) -great for teaching the different parts of the Atom! The kids WILL sing it! This song originally only had 2 verses when it was first published and a student in my class wrote the verse.
This would go with a lesson on habitats. I would cut out the flash cards and incorporate this activity into the centers, so that the kids could practice matching the specific animals, with the proper habitats.
