About This Quiz

Science is one of the most fascinating subjects and yet one of the most misunderstood. It's the study of how our world works: why the sky is blue, why the stars appear to rotate in the sky, how sick people can be made healthy, how planes stay in the air, and a whole host of everyday miracles. Simply having a good sense of how all of this works makes the world a great deal more comfortable. Things that might otherwise seem arbitrary suddenly fall into place, and everything is more orderly and predictable.

Of course, not all of us are blessed with a great scientific instruction in our upbringing -- but all of us can grasp many of the basics simply by being curious and paying attention. So let's see whether you have been doing just that. Do you know the names of all the planets and their orders? Do you know what the force is that keeps water in a spinning bucket? Are you familiar with which areas of study fall into what branch of science, and where and how it might interact with other branches? How about knowing basic terminology in some of these branches? It's time to put your science mind to the test!

The Big Bang Theory is a scientific theory that speculates about what aspect?

Scientists theorize that the universe has been expanding since it was created. And the creation theory they have is called the Big Bang Theory, where a general explosion happened which led to the creation of the universe. What a booming beginning!

Dinosaurs were recorded to have appeared first during the Triassic period. They are technically reptiles, but they got really huge!

While hydrogen is the most present element in the whole universe, what element do humans need to breathe here on earth?

Oxygen is technically a gas. It’s an important element to have the respiratory system work in all types of living organisms, especially human beings.

In chemistry, all the elements and their individual details are neatly arranged using a certain system. What do you call this system?

The Periodic table of elements is a neatly arranged table charting all known elements and their corresponding details. The system subdivides elements into metals, non-metals, and gases. You should see a live version of it, containing samples of the elements!

This double helix-shaped thing inside all humans carry our genetic information. What’s it called?

The DNA is technically a molecule that carries our genetic information. Its double helix structure is very familiar to us today since many scientific and even non-scientific pop culture products use the image often.

The universal Three Laws of Motion were theorized by which scientist?

Isaac Newton formulated the Three Laws of Motion. These laws govern a body and the types of forces that could act upon it. The motion part is how the body reacts to these forces.

When you’re studying things like matter, motion, energy and force, which branch of science are you dealing with?

The basic behavior of the universe, in relation to space and time plus matter and motion, is what physics is all about. It is considered as a natural science.

If the planets are part of a solar system, what do you call the larger structure that encloses the solar system?

A galaxy is a huge system made up of many smaller subsystems like our solar system. There are three categories of galaxies, namely the elliptical, the spiral, and the irregular kind.

The troposphere and stratosphere are layers of what?

The earth’s atmosphere is actually is made up of several layers. The most common we know — and the ones nearer to us — are the troposphere and stratosphere. The others are mesosphere, thermosphere, and the exosphere.

Flora refers to the vegetation or plant life specific to a certain timeframe or place. What is its partner term that refers to the animal life?

Fauna is the term that refers to the wildlife of a particular region and/or era. It’s the tandem term for flora.

Approximately how many bones does an average human adult body have?

Humans are born with nearly 300 bones in our body at first. But since the body evolves as we age, with some bones fusing together, the total result of our adult body bone count shrinks to nearly 200 — or 206 to be exact, for the average adult.

Marianas Trench is recorded to have this kind of feat regarding ocean history. What is this record?

It’s in the Pacific Ocean where you can spot the deepest part of the earth’s waters. It’s called the Marianas Trench, or Mariana Trench since it’s near the Mariana Islands near the Asian country of the Philippines.

He is the Greek scholar, upon discovering an important scientific fact, exclaimed “Eureka!” Who is this?

Which planet holds the record for being the hottest one in our solar system?

Venus holds the distinction of being the hottest planet in our solar system. This is because its atmosphere creates a kind of greenhouse effect with the trapped acid gases in it that heats off its surface, reaching more than 400 degrees Celsius!

The human blood contains WBC and RBC, with W meaning white and R meaning red. What does BC mean?
