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.

Carbohydrates

By Janice VanCleave

Carbohydrates, also called saccharides, are organic chemicals found in plants. The two basic structures of carbohydrates are simple and complex.

Simple carbohydrates are also called simple sugars and yes, they have a sweet taste.The simplistic nature of these chemicals has to do with their molecular structure. As the name implies, the structure of these molecules are simple and small.  The two basic types of simple carbohydrates are  monosaccharides (made of one sugar unit)  and disaccharides (made up of two sugar units).

The diagram uses two colored boxes to represent two different  monosaccharides. Using the two monosaccharides as the building blocks for disaccharides, three different types of disaccharides are modeled.

Complex carbohydrates, also called polysaccharides, are chains of three or more simple carbohydrates linked together. Starch and cellulose are examples of large complex carbohydrate molecules.
