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/Hypothesis

By

Step 5: Hypothesis

A hypothesis is your guess about the answer to the project question. This is not a “wild” guess. You need to have a good reason for the hypothesis you state.

Example:

Project Question

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

independent variable: viscosity of glue

dependent variable: viscosity of slime

Project Hypothesis

Examples:

1. Viscosity measures how easy something flows. Glues that are thick and slow to flow will produce thick, slow flowing slime.

2. Viscosity is the resistance to flowing, so the more viscous the glue the more viscous will be the slime.

Step 6 : Experiment
