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.

Super Cool Crystalization

By Janice VanCleave

How to Make a Soda Slushy Super Cooled: An aqueous solution is super cooled when it is liquid at a below the freezing point of water (32oF (0 oC). Crystal:  Solid, 3-D matter made up of atoms, molecules, or ions in a regularly ordered pattern. Crystallization: The process of matter changing into a solid crystal state; Pressure: A […]

Crystals

By Janice VanCleave

Crystals are solids with particles arranged in a regular, repeating pattern with flat surfaces. Most solids are crystalline solids. The crystal diagram shown is of quartz, which is made of silicon dioxide, the same chemical found in sand.  Without any impurities, quartz is colorless and transparent. Impurities, such as iron,  give quartz crystals a pink […]

Borax Crystals

By Janice VanCleave

Borax is combined with laundry detergent to clean clothes. Borax is the common name for Sodium Borate.

Need a Fast Growing Crystal? Borax crystals form from a Supersaturated Borax Solution  in about three hours. Recipe for a Supersaturated Borax Solution1. Mix 1 cup of borax and 2 cups of water in a cooking pot.2. Heat the mixture to boiling, stirring so that the borax thoroughly mixes with the hot water. All the […]

What is Table Sugar?

By Janice VanCleave

Table sugar is commonly used to sweeten food. There are different kinds of sugars, including glucose, fructose, and sucrose. Glucose is commonly called blood sugar; fructose is sugar in fruit; sucrose is table sugar.  Sucrose is a carbohydrate, which is a chemical made of carbon, hydrogen and oxygen. Sucrose molecules contain 12 atoms of carbon, […]

States of Matter: Solid

By Janice VanCleave

Matter exists naturally in four states. These states in order of energy from least energy to greatest energy are: Solid Liquid Gas Plasma A SOLID is the state of mater with the least amount of energy and the most structure. Solids exits in two basic forms: 1. Crystalline solids are those in which the particles […]

Types of Crystals

By Janice VanCleave

Halie Crystal

CRYSTALS are solids with particles arranged in a regular, repeating pattern with flat surfaces. Most solids are CRYSTALLINE SOLIDS, which are solids made of crystals. For example, when liquid water freezes, the water molecules link together forming ice crystals. A large piece of ice is made up of many small ice crystals that fit together […]
