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.

Science Project: Slime/Question

By Janice VanCleave

Step 4: Project Question

A science fair project question identifies two variables:

the independent variable

the dependent variable.

Example Questions:

The independent variables are in purple type.

The dependent variables are in bold type

1. If two solution, glue and borax, are mixed, what effect would the type of glue used have on the viscosity of the slime?

2. If two solution, glue and borax, are mixed, what effect would the concentration of glue have on the viscosity of the slime?

3. If two solution, glue and borax, are mixed, what effect would the concentration of borax have on the viscosity of the slime?

4. If two solution, glue and borax, are mixed, what effect would the ratio of the solutions have on the viscosity of the slime?

Step 5: Hypothesis
