Indicators Acid Indicators are materials that change color in an acid solution. Base Indicators are materials that change color in a base solution. Acid/Base Indicators are materials that have one color when mixed with an acid and another color when mixed with a base. Red Cabbage Juice is an acid/base Indicator. The juice has a […]
Insect Proboscis
Fly Straws Flies don’t chew their food like we do. Instead they drink their food through a straw-like mouth part called a proboscis. We don’t have to drink our food, but sometimes it is fun, especially if you have fun straws. Drinking liquids through a straw is easy, but if the food is very thick […]
Variables For Making Rock Candy
A Science Fair Project is a cause/effect investigation. The cause is called an independent variable (something you purposely change). Changes in the independent variable affects another variable called the dependent variable. You AFFECT the investigation by making changes in the independent variable. The objective of the investigation is to measure the EFFECT that this change […]
Fly Digestion
Barfing Flies Did You Know…Flies taste with their feet? Insects have taste organs which are usually located on their mouth parts; but some insects, such as house flies can taste with their feet. When a fly walks on your pizza, nerves in the fly’s feet detect the presence of different chemicals in the food and […]
Capillary Action
Capillary Action is also called wicking, which is the ability of a substance to draw another substance into it. In the diagram, three different size glass tubes are standing in a container of colored water. Notice that the water rises to a different height in each of the tubes. The more narrow the tube, the […]
Symmetry: Butterfly Wings
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 […]

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 […]

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 […]
