ABOUT THE SOUND PICTURE

With mouth wide open, vibrating air coming up the throat from the vocal chords leaving the open mouth and spreading in all directions. Hi, I am Janice VanCleave, author of 50+ best-selling science experiment books for children ages 4 through high school. I taught science for 27 years and now am creating this science website.   My scream was not staged. The picture was to be of two adult cats, which I was holding. A microsecond before the camera snapped, the two cats dug their claws into my skin as they prepared to leap out of my arms. A picture like this is great for making inferences. Kids could make "guesses" as to why I am screaming. They would be drawing on facts from the photo, such as I look like I am in pain or maybe I am just pretending.

Biochemistry: Bromelain

By Janice VanCleave

Pineapple contains an enzyme that digests protein.
Question:

Why does my tongue hurt when I eat fresh pineapple?

Answer:

Fresh pineapple has bromelain, which is the mixture of two protein-digesting chemicals. Your tongue, and lips as well as the tissue inside your mouth is made of protein which the bromelain can and does digest. YIKES!

1. Can you eat too much pineapple? Too much is relevant, meaning just how much pain can you endure. Eating pineapple affect some people more than others. It can definitely irritate your lips, tongue and lining inside your mouth. Also, pineapple contains acid which adds to the damage.
2. Does the bromelain digest your stomach and intestines?  No, because these organs have protective lining.
