Butterfly wings are beautiful examples of symmetry, which means that the wings on one side of the body match the wings on the opposite side of the body. Instead of the word match, let’s say the wings are mirror images of each other. Mirror images will perfectly fit together. When a butterfly folds its wings […]

Science Projects about Rocks and Minerals
What are Rocks? Rocks are a mixture of different kinds of minerals. What are Minerals? The following definitions on what constitutes a mineral information is from B and L Fine Minerals. The definitions are from different were taken from several different sources and are arranged by year. “A mineral is an element or chemical compound […]

How to Grow Salt Crystals
How to grow Halite Crystals Materials: tap water, measuring cup, tablespoons of table salt, stirring spoon, tray (large enough to hold the paper), 1 sheet of black construction paper Procedure: 1. Fill the measuring cup with 1/2 cup (125 ml) of water. 2. Make a salt solution by adding the salt to the water. Stir […]
Polymer
A polymer is a very long chain-like molecule. Poly means many and mer means unit. A polymer is made by bonding (linking together) many small molecules called monomers (one unit). Polymers can be made of kinds of monomers and they can be linked together in different ways. A model of a polymer, such as the […]
Earthworms: Food Web
Question: What kind of food web are earthworms part of? Answer: Earthworms basically get their nutrition from fungi and bacteria. In turn, earthworms promote the activity of these organisms by shredding and increasing the surface area of organic matter so that it is more available to these small organisms. Earthworms are invertebrates, which means they […]
Earthworms: Recyclers
Question: Why are Earthworms important? Answer: Earthworms Churn the Soil and Make it Porous As earthworms eat their way through soil, they break up hardened soil. Earthworms Improve Water Infiltration Rates The maze of tunnels create as earthworms eat their way through soil allows water as well as air to better mix with the soil. […]
Crystal Project: Variables
A variable is something that can change. For your science fair project, you should change one variable to see what affect it has on another variable. These two variables are: independent variable: Something that you choose to change. dependent variable: Something that changes in response to changes in the independent variable. 1. Following are ideas […]
Types of Crystals
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 […]
Halite Crystals: Research
Research is any process that results in the collecting of information about a specific topic. This can be done by reading information recorded by others and/or your own observations and experiments. Research: Reading Following are links to research information about crystals. TYPES OF CRYSTALS HOW CRYSTALS FORM Research: Experimental Exploratory experiments are done for the […]
