All of us, at one point or another, have seen a megaphone. There are two main types of megaphones. The first type is the simple cone-shaped megaphone seen at many sporting events. It is also often seen in old movies where we see a film director yelling, "Quiet on Set!" or "Action!". The second type is the electronic megaphone. The electronic megaphone is also commonly seen in movies, usually in a police officer's hand as they try to talk to a hostage taker or a person threatening to jump off of ...

Everything around you can be measured example- the food you eat, say you want to cook 1 kg of rice. Kg is a unit of measurement. The distance between two planets too can be measured, even the width of a bacteria can be measured. See how important measurement is. This experiment is about how to measure objects accurately using a ruler as well as how to measure the temperature of an object accurately.

In earlier studies, some physical attributes of humans were considered Mendelian in nature, but further study suggested they are in fact not. These traits may involve more complex genetic models that usually include more than one gene. Examples are the color of the eyes and hair, and tongue rolling. Gene dominance plays a part in these traits, but information from other genes are also involved.

Plant morphology, also called phytomorphology, is the study of physical characteristics of plants. Plant morphology utilizes a wide number of various terms in describing organs and parts of plants which can be seen by the eye using a magnifying lens. Plant morphology terms are used in the identification and classification of plants. Morphology is comparative in nature as morphologists (or those who study morphology) study structures in different plants of the same species, drawing comparisons an...

What exactly is PCR and how does it work? PCR, also known as Polymerase Chain Reaction, is a method that many scientists use to replicate DNA. This is done in three steps. These steps are denaturing which is where the DNA double strand is heated and melted. The next step is annealing which is where primers and DNA polymerase attaches to the single strand DNA. The last step is elongation which is when the temperature is increased to optimal conditions for the DNA polymerase to begin synthesizing ...

Whether we observe the universe from a microscope or telescope, every scale of our existence fractals in self-similarity. Atomic structures of all shapes and sizes contain the same invisible, empty, energetic space. In fact, atoms are said to be 99% hollow and only ~1% physical. So, what does this really say about us (humans)?

We are familiar with watermelons with red flesh. But watermelons are more than that. There are varieties with amazing colors, taste, aroma, skin design, and size. Though it originated from Africa, it has since been cultivated extensively in many parts of the world including China, India and the USA. The watermelon rinds are normally eaten raw or used as ingredients for salads; but for some other cultures, they are stir-fried, stewed, pickled, or prepared into juice or wine.

A summary of different experiments conducted by the great scientists of the 1900's. Each experiment continued to build on data which ultimately lead to the discovery what we find obvious today, that genes are composed of DNA. By revisiting these experiments, we learn the many factors that are included in lab work and exciting research that has shaped the field of genetics in the past years.

Prior to the invention of airplanes, one of the fastest and the most effective means of mass transportation are trains Freight and passenger trains were widely used worldwide to transport passengers and commodity goods. These trains can average nearly 2,000 meters in length especially freight trains in particular. Today, trains still play one of the most vital role in transporting commuters, raw materials and finished products. They are much faster, safer and longer. Here are some of the longest...
