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.

A Blutterfly’s Life Cycle

By Janice VanCleave

Metamorphosis is a term used to indicate something changing, such as the life cycle of a butterfly. The stages of this cycle are: 1. Eggs are laid on a plant leaf. Each egg develops into a caterpillar. 2. Caterpillars look much like tiny thin worms at first. They eat on the leaves of the plant […]
