Chlorophyll is an organic molecule. The basic organic molecule is composed of carbon and hydrogen. More complex organic compounds contain carbon, hydrogen, and other elements such as oxygen and nitrogen. A chelate is an organic compound with a central metal ion. Chlorophyll is one of the most important chelates in nature. In the diagram, the [...]
Why was the cloned sheep called Dolly named after the Country Western Singer, Dolly Parton? The cells used to clone Dolly came from the breasts of Dolly’s mother. Dolly Parton is known for her large breast, so the scientists named the cloned sheep Dolly. More Information about Dolly Dolly was born July 5, 1996 at [...]

The best TEACHING TIP I have for club directors is to support and encourage children’s inborn gift of curiosity One way is to explore the fun of science TOGETHER. Instead of [...]
Matter is anything that has mass and takes up space. Mass is defined as the amount of matter that an object is made of. YIKES! Matter has mass and mass is made of matter! This doesn’t tell me what these terms mean. UUM!! For now, let’s say that mass is the amount of STUFF that [...]

For example: The gene for eye color. allele One member of a pair of genes that occupy a specific position on a specific chromosome. dominant allele Represented by a capital letter. The gene [...]
Pond water contains some living creatures that are too small to be seen with the naked eye (without a microscope). Some of these creatures are made of only one cell. The paramecium is one such creature. Paramecium are sometimes called “slipper animals” because they are shaped much like the sole of a shoe. Paramecium move [...]
What is Newton’s First Law of Motion? Newton’s first law of motion is about inertia. While this might sound technical, it’s not. Inertia is a characteristic of an object’s state of motion. Well, this doesn’t sound very easy, so let me try again. Actually, I am writing this so that a special technical reviewer, [...]
A complete flower has these four basic parts: The carpel is the bottle -shaped structure in the center of the flower. Its top opening is called a stigma, followed by its neck (style) and rounded bottom (ovule). Stamen Petals surround and protect the carpel and stamen. Sepals are leaf-like structures that surround and protect the [...]
Gravity is a force between materials. The greater the mass, the greater the force of gravity, so things that have a lot of mass, such as the planet Earth, pulls things with less mass, such as a chunk of rock, to its surface. As shown in the diagram, the winner of the gravity tug-of-war between [...]
