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.

Hypothesis

By Janice VanCleave

A hypothesis is something that everyone gives multiple times each day, but few people can explain what a hypothesis is.

A hypothesis can also be defined as a prediction about the outcome […]

 The Big Dipper is Not a Constellation–It is an Asterism. Astronomy is a topic that many avoid when choosing a science project topic. This is because many think you have to have an expensive telescope to do studies. NOT SO!!! There are so many wonderful studies that can be done with your unaided eye–your naked […]
