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.

Chemistry: Matter

By Janice VanCleave

Notes from Janice’s Desk

Chemistry is one of my favorite sciences. Actually, I am not sure which I like the best, chemistry or physics.  But there is such an overlap of between all the science, so I guess I like them all.

matter

Chemistry is the study of the properties (characteristics) and behavior of matter. Physics deals more with the motion and energy of matter. Astronomy is matter in the whole universe, biology deals with matter in living organisms, earth science is the matter of the Earth, and so forth— Matter is the core of all sciences.

Matter is the stuff that everything is made of. For more information about matter, see        MATTER: SPACE

More Later,

Janice
