How to Write a Science Project Question

By Janice VanCleave

You need to understand about variables before you can write a question for your science fair project. A variable is a part of an experiment that changes, such as temperature, amount of light, size, or color. The objective of a science fair project is to have only two changing parts, Part A and Part B. […]

Gases Have Volume

By Janice VanCleave

Chemistry is the study of the composition, structure, properties, and interactions of matter. Matter is all the material in the universe. Simply, matter is the stuff that things are made up of. Matter has mass and volume. Mass is the amount of material (stuff)  something is made of. Mass is not affected by gravity. Materials are […]

Fun Facts Diamonds

By Janice VanCleave

diamond pendant

1. Diamonds cut before 1950 are shaped differently from most diamonds cut since then (today). The “Antwerp Cut” was developed in the 50s; they found a shallower geometry which distributes more light (more sparkle). See the gallery for a diagram. 2. You can be a real diamond miner for a day in Canada. There are […]

Solutions are Homogeneous Mixtures

By Janice VanCleave

Mixtures are a Combination of Two or More Parts. Solutions are a type of mixture in which one substance dissolve in the other. The substance in a solution that dissolve is called a solute (solid, liquid, or gas). The substance in a solution that does the dissolving is called the solvent (solid, liquid, or gas). […]

Fluorescent Highlighters

By Janice VanCleave

Fluorescent highlighters are extra bright in sunlight, but not so different than other highlighters under a desk lamp. This is because two bundles of light energy is being sent to your eyes and both are for the same color. This makes the color more intense–louder–brighter–super-bright. Let’s consider a yellow fluorescent highlighter. One source of light […]

Teaching about Gravity using Science Magic

By Janice VanCleave

Using gravity you can cause an unattached rope to seemingly lift a bottle. As with all magic–its a trick. In this trick, gravity is used to pull a ball into place so that it presses so hard against the rope that it cannot move. 1. Ask an adult helper to cut a slit in the […]
