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.

Direction of the Moon’s Terminator

By Janice VanCleave

Question: How can one identify a waxing Moon from a  waning Moon? Answer: The Moon’s terminator is  an imaginary line dividing the lit and unlit parts of the Moon disk seen from Earth. A waxing Moon is growing. This means its lighted part is increasing. A waning Moon is shrinking. This means its lighted part […]

Atomic Theory

By Janice VanCleave

I like reading about the history of science. Some of the ideas of scientist of the past seems so silly. How could such smart people have such dumb ideas? But, then I wonder if the scientific facts we are learning today will seem silly to people in the future. Maybe! But for now let’s have […]

Atomic Model

By Janice VanCleave

The best part about writing on a blog/website is the interaction with other educators. For example, I recently posted an investigation about rolling a marble toward an object and observing the path of the marble before and after it hit the object. The investigation models how scientists discovered the parts of an atom without being […]

Atomic Models

By Janice VanCleave

I am a visual learner and often make models so that I can understand a concept. Since I seem to be challenged when it comes to spacial orientation, I need models for things that are three dimensional. For example, atoms and their parts and especially how scientists find out about the parts of atoms without […]

Subatomic Parts

By Janice VanCleave

atomic structure

Did You Know? Atoms have a central area called the nucleus. Protons are positively charged particles in an atom’s nucleus. Also in the nucleus are neutrons, particles with no charge. Neutrons and protons have about 2000 times as much mass as do electrons, thus the nucleus is the most massive part of the atom. While […]

Periodic Table Game

Periodic Table

By Janice VanCleave

Chemistry is such a fun course and so applicable to daily living. I’ve been thinking about an interesting way for kids of all ages to learn more about chemistry. One of the most important chemistry learning tool is the periodic table. So, I have designed an activity that introduces some of the elements on the […]
