When it comes to science, there are so many ologies your head could explode. If there is a subject, there is more than likely a study of it. For example, theology is the study of religion. Many people will look to theologians to resolve crises of faith. There's astrologists, those who claim to either know the future or actually do have psychic gifts. While many go to these specialists to get spiritual advice, you don't ever want to confuse these folks with astronomers. An astronomer studies astronomy, not astrology: the study of natural celestial bodies in space. This confusion is an area of contention, and you don't want to rub the person the wrong way.
Just like the number of various studies of science, there are just as many pieces of equipment that help aid the scientist to prove whatever theory they're hoping to prove or disprove. In addition to this, there is personal protective equipment to help keep those experimenting from getting hurt or destroying the lab.

The stamen has three basic parts: the anther, which brushes against the pistil to start pollination, pollen sacs that create and hold the pollen, and filaments, the small stalks that help support the stamen.
In the world of fitness, there are a few workouts that are considered anaerobic: sprinting, heavy weight training and jumping. All of these exercises have one thing in common: They all have short bursts of energy, making it a high-intensity workout.
The center of a nucleus has two types of particles: positively charged particles (protons) and uncharged particles (neutrons). Regardless of the number of neutrons in a cell, the protons will make every nucleus positively charged.
When an atom has more electrons than protons, it is called a negative ion. Contrary to its name, negative ions are actually good to have around: They absorb free radicals and remove pollution in the air, purifying it.
Every element is grouped into a family, where there is one thing that they all have in common. A couple of families listed are the transition metals (which include silver and gold) and the non-metal family (which includes oxygen and carbon).
When a compound is written, it usually has a combination of letters and numbers. For example, if you take one hydrogen atom and add two oxygen atoms, you get water. The way it is written is H2O.
Steam, evaporated water, is used in many different ways. In the world of cosmetology, a facial usually uses steam to help loosen pores, and steaming is also a method of preparing vegetables.
When it comes to illustrating how a lever works to children, oftentimes a teeter totter is used with one child sitting on the ground the other in the air.
Balloons float because of a noble gas: Helium has the atomic number of two and is the second lowest element on the periodic table. Another element, neon, helps illuminate neon signs.
Alloys are usually made to strengthen the two originating metals as well as protect it from corrosion. Two examples of an alloy are bronze, which is a mixture of copper and tin, and brass, which is a mixture of copper and zinc.
Ever wonder why you can only see a rainbow during a light rain? That's because light is hitting some of the water droplets, creating a natural prism.
One of the reasons why wires have a plastic coating on them is to help protect them, the other is to help contain the energy they are transmitting.
In addition to Orion's Belt, all the signs of the zodiac are in the stars. How do you know what sign you are? If you look to the stars on your birthday, your zodiac's constellation will be visible.

A typical geode starts out with liquid filling and forms a valve. As the liquid evaporates, crystals form.
A good example of a homogeneous rock are lava rocks. Unlike a heterogeneous rock, the bond between the two elements is so tight that it is very difficult to separate.
A good example of a heterogeneous rock is granite. Unlike a homogeneous rock, the bond between the two elements is pretty loose, so it is very easy to separate.
Carapaces are usually made of bone or chitin. Other animals that have carapaces include scorpions, spiders, crabs and shrimp.
One distinct difference between a group of plant cells and a group of animal cells is that plant cells have a tight wall-like structure, where animal cells are loose.
In order to protect the specimen from damage, a small piece of plastic (called a coverslip) is placed on top of it, compressing it, making it easier to view. This method of slide mounting is called wet mounting.
Depending on the size of a cylinder, you could also use it for creating mixtures. Because the size of the cylinder can vary, the amount of liquid that is measured can be greater from one cylinder to the next.
Petri dishes are usually lined with gelatin, which help feed the bacteria, encouraging growth. In order to protect the specimen, each dish comes with a lid.
With the exception of some single-celled organisms, most of the creatures on our planet need oxygen to function. In the world of fitness, aerobics classes are designed to help strengthen the lungs through vigorous exercise.
A majority of the creatures that live on the earth are considered vertebrates. The creatures without spines are usually protected by an exoskeleton.
Many of the invertebrates that live on Earth are protected by an exoskeleton. Some examples of invertebrates are starfish, mollusks, arachnids and insects.
Fracking, a drilling method to get oil, causes quite a bit of damage to the Earth's upper crust. When you remove minerals from the Earth without digging, it could cause earthquakes.
Made of water vapor, a cumulonimbus cloud is an easy way for the atmosphere to transfer water from one part of the planet to another. They occupy low to medium altitudes.
