Next, Barry sees Diamond grooving on the dance floor! Diamond is moving to the beat, because she can hear the music that is playing from the speakers.
The music is forms of sound waves that travel inside your ears. Diamond can hear the music because it's sound waves enter her outer ear, then hit her ear drum, where the sound then travels to the inner ear, the cochlea, which makes the sound louder for our brain to understand.
Here, Barry the bird sees Christina petting her dog. Christina can feel her dog using her sense of touch.
Christina knows she is touching her dog because she can feel the warmth coming from the dog's body, and she can feel the pressure on her hand when she pushes her hand onto the dog.
Christina is also using her sense of smell to smell all the different kinds of flowers around her. Christina's nose has nostrils, or nasal passageways, where the air particles go when you breathe.
Much like bees sense chemicals and go to flowers for their pollen, we smell the chemicals called pheromones and they make up the smell of each flower.
