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.

Testing the Strength of a Thigh Bone Model

By

The long bone in your leg, called your thigh bone, is shaped much like the bone in a chicken’s leg. Both have a hollow, cylinder-like shape, which means they are shaped like a tall soup can.This shape makes the leg bone lighter than it would be if it were solid throughout.

Calcium in Bones

By

Facts About Bones! The hard part of bone is made up mainly of the chemical calcium phosphate. Fibers called collagen (a protein) run through the calcium phosphate. The calcium phosphate gives bones firmness and strength, and collagen gives them flexibility. The vinegar reacts with the calcium phosphate, thus removing the calcium from the bone and […]
