What is a Supersaturated Solution?

By

What is a Solution? How do You Saturated A Solution? A solution is  a homogeneous mixture, meaning it is the same throughout. A solution can be made of more than two substance, with one of the substances being the solvent and the substances that dissolve in the solvent are called solutes. You make and use […]

Balloon Rocket Projects

By

Science Fair Project Category: Astrophysics Topic: Balloon Rocket Introduction The development of the science fair project described in this booklet can be used for any 6th through 12th grade student. This is because the basic process is the same no matter what grade you are in. The difference is in the complexity of the project. […]

Crystalline Solids

By

Crystalline solids are solids made of crystals. Crystals are solids with flat surfaces. Crystals are made of chemicals arranged in a regular, repeating pattern. Crystals are made of chemicals that fit together much like a puzzle. The shape of a crystal depends on the shape of the chemical building blocks that it is made of. […]

Sky Color

By

Blue Sky The sky appears to be a colored surface above the Earth. During the day the sky’s color varies in shades of blue. At sunrise and sunset its colors may be vivid shades of red, pink, orange, yellow, and blue. Your eyes have special light receiving cells called cones. These cells take in light […]

Gold Isotopes

By

Atoms are the smallest particle of an element that retains the characteristics of the element. For Example: The gold nugget in the diagram is made up of individual gold atoms. Gold Atom Diagram The circle represents the nucleus of a gold atom. Outside the nucleus of the gold atom are 79 electrons (negative charges). Electrons […]

Science Project: Halite Crystals

By

Halite is a mineral with a cubic geometric shape.  Halite crystals form when water evaporates from a sodium chloride solution. Crystals forming due to evaporation are called evaporites. Thus, halite crystals are evaporites. Discover for Yourself You can grow halite crystals using table salt, which is the common name for sodium chloride. Make a saturated solution […]

Each diagram on this page gives instructions for making a special curvy circle that will be used in a magic demonstration. When you have made the three Möbius strips, instructions for using them in a magic of science demonstration can be found  HERE Strip #2Directions for making the magic strips. Notice that for each step […]

Diamonds to Gas

By

Smoking Diamonds Did you know that a diamond will burn? At one time it was believed that objects burned because fire could enter them. Very hard things didn’t burn because there was no spaces for the fire to enter. Thus, diamonds were thought to be too hard to burn. Many early “scientists” did not experiment […]

Air Pressure vs. Altitude

By

The gravitational attraction between the Earth and its atmosphere is greatest near the Earth’s surface. As a result, the density of air molecules  is greatest near the Earth’s surface and decreases as the distance from Earth’s surface increases. The greater the density of air molecules the greater is their pressure. Air pressure is greatest at […]
