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.

Scientific Method:Conclusion

By

Conclusion is the seventh step of the scientific method. This is the finale –if you know how to use a computer, you might type this part. The conclusion doesn’t have to be long, but it does need to address your hypothesis. In other words, did your experimental results support your hypothesis or not?  As a […]

Scientific Method: Results

By

Today, I’ll introduce the 6th  step of the scientific method–the Results, which is the analysis of the experimental data. As a reminder, the symbol in the upper left corner of this page links to each step of the scientific method as it relates to an investigation about mixing blue and yellow paint. While each step […]

Scientific Method: Data

By

Today, I’ll introduce the fifth step of the scientific method–the DATA. As a reminder, the symbol in the upper left corner of this page links to each step of the scientific method as it relates to an investigation about mixing  yellow and blue paint pigments (chemicals that give a substance color). Now about Data—Data is […]

Scientific Method: Experiment

By

STEP FOUR of the scientific method is the topic for today. After completing the first three steps you are now ready to get to the business of experimenting. YEA! This is the real fun part. While experimenting is fun, it does have a purpose, which is to determine if your hypothesis is valid. You must […]

Scientific Method: Hypothesis

By

Today, I’ll introduce the THIRD STEP of the scientific method–the Hypothesis.This always seems to be a problem when it is really the easiest part–it is your personal prediction of the result of the experiment that you will do to answer the question you expressed in STEP TWO. If you are just now tuning in to […]

Scientific Method:Question

By

Today, I’ll introduce the second step of the scientific method–the Question. As a reminder, the symbol in the upper left corner of this page links to each step of the scientific method as it relates to an investigation about mixing two pigments (chemicals that give a substance color). The Investiggation Symbol is linked to the […]

Air Pressure:Elevation

By

I love driving around in Colorado. It is such a beautiful state. One summer during our drive we heard a very loud pop. It didn’t sound like a blown tire and I still had control of the car. So what blew up.  I stopped the car and my husband checked all the tires. No problem […]

Earth Science: Atmosphere

By

Question: What is the atmosphere? Answer: The “blanket” of air that surrounds the Earth is called Earth’s atmosphere. Question: Where in the atmosphere is greatest concentration of air? Answer: The layer of air next to Earth’s surface is where Earth’s weather, including clouds occurs.This bottom layer of the atmosphere has the greatest density of air. […]
