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.

Step 7: Controlled Experiment

To conduct a scientific investigation, care must be taken to follow experimental procedures. You must design an experiment to test your hypothesis. When planning your experiment remember to:

* Keep everything the same except for the single variable being tested, which for this science fair guide about using slime for the experimental experiment, the independent variable is :

INDEPENDENT VARIABLE: the viscosity of the glue

* A Controlled Experiment should be used. This experiment will be used as the standard. This means that you will use glues with different viscosities and compare the viscosity of the slime made with the SLIME’S VISCOSITY MADE WITH THE CONTROLLED EXPERIMENT.

Since the original experiment specified Elemer’s White School Glue–use this as your CONTROL EXPERIMENT (your standard).
