About This Quiz

The thighbone is connected to the what bone? Can you tell the difference between a cell and an organelle? What's your take on continental drift theory? You'll get plenty of chances to address these and other sciencey stuff with this science quiz. Biology, astronomy, geometry, chemistry and physics are all covered in this super fun survey of how the natural world works.

Basic brain anatomy deals with three main areas. Are the names of these zones stored somewhere inside your cranial dome? If not, don't worry. You'll secure those facts and more in just a few scrolls. But before you give this exam your best shot, enjoy a few pointers for review. Certain creatures covered here are single-celled organisms, dinosaurs, insects and humans. Yes...humans are creatures too, according to science. And as far as chemistry is concerned, arm yourself with an intermediate understanding of the elements, their natural purposes and behaviors in relation to other elements or compounds. Physics facts make an appearance on this test. Nail the basics on speed, constants and intervals and you'll go a long way.

Now go strong and score big!

The sun's surface measures approximately 5,800 kelvins. The sun is a star and the dominate force of the solar system around which the Earth and other planets orbit.

What substance is called the "universal solvent"?

Water is often known as the universal solvent because of its ability to dissolve many substances. Water is the main constituent of most living organisms.

What is the first element of the periodic table?

Hydrogen is the first element of the periodic table and is placed in group 1, but it is not considered an alkali metal. Of all the elements, hydrogen is the most abundant chemical element.

The boiling point of a liquid substance is the temperature at which the pressure applied by the surroundings upon the liquid is matched by the pressure of the liquid vapor. When this pressure equalization occurs, liquid transforms to gas without a temperature increase.

Which structure of the brain is not contained in the cerebrum?

The three main parts of the brain are the cerebrum, cerebellum and the brain stem. The cerebrum is the largest part of the brain that contains the hippocampus, basal ganglia and olfactory bulb. The cerebellum is based just below and behind the cerebral hemispheres.

What part of a microscope holds a specimen in place?

Scientists use microscopes to examine small specimens that are difficult to analyze without the aid of an enlarged image, which microscopes provide. Two common types are the electron microscope and the light microscope.

What is the rigid outer section of Planet Earth called?

The term "lithosphere" is derived from the Greek word "lithos" meaning "rock." The lithosphere is the solid outer layer of the Earth which includes the Earth's crust.

8 of 35
What type of charge does a valence electron carry?

Valence electrons are negatively charged particles that dwell in the outermost region of atoms. They are essential in the creation of chemical bonds.

9 of 35
Which cell structure is responsible for generating large amounts of energy?

A mitochondrion is a specialized cell structure found in the cytoplasm of practically all cells with delineated nuclei. The energy that mitochondrion generate come in the form of adenosine triphosphate (ATP) molecules, which capture energy from food and distribute it as fuel for other cellular activities.

Which part of the human body safeguards the trachea from food inhalation?

The larynx is located in the neck of mammals, amphibians and reptiles. This vital structure protects from breathing in food particles. It's also used for creating sounds and breathing.

11 of 35
Who invented the electron microscope?

Electron microscopes are powerful magnifying devices that achieve high resolution using an electron beam as opposed to a light ray. Many research laboratories use light microscopes to support electron microscopy.

12 of 35
What is the name of the theory that posits that all the continents were connected at one point?

Continental drift recognizes complementary shapes of continents that appear as if they could fit together like pieces of a jigsaw puzzle. The concept of earth plate shifting, or tectonics, incorporates this theory.

The carpal canal is located in which human structure?

The system of eight bones in the wrist is referred to as the carpal bones or the carpus. The wrist joint is also called the radiocarpal joint.

How many miles is the planet Mars from Earth?

The distance between Earth and Mars varies depending on the position of these two planets which orbit the sun. Mars is the fourth planet from the sun, and Earth is the third planet from the sun. On average, Mars is 225 million km from Earth.

15 of 35
Which of these elements is not an alkaline earth metal?

Hydrogen is a flammable, gaseous substance. It has a single positively charged proton in its nucleus and one negatively charged electron. Hydrogen is the lightest chemical element of the periodic table.

What is the name of the instrument used to measure the altitude of the land surface?

Aside from measuring the altitude of the land surface, altimeters can determine the elevation of any object in relation to ground level or sea level. Radio altimeters measure the distance above water or land by recording the time it takes for sound waves to travel from an elevated object to the Earth and back. Pressure altimeters measure atmospheric pressure above sea level to determine altitude.

The freezing point is the temperature at which a liquid becomes a solid through increased pressure. The composition of the solid changes from that of its liquid state in a way that tends to lower the substance's freezing point.

What is the name of the colored eye structure that's a ring-shaped membrane behind the cornea?

For most mammals, the iris controls the size and diameter of the pupil which also regulates the amount of light that reaches the retina. A person's eye color is determined by the iris color.

What is the structure of the heart that pumps blood out of the heart into the circulatory system?

A heart ventricle is a muscular chamber that pumps blood out of the heart and into the circulatory system of an organism. Humans have two ventricles called the left ventricle and the right ventricle, which are the two lower chambers of the heart. The right ventricle supplies blood to the lungs, and the left ventricle pumps blood to the aorta, which then supplies blood to the body's tissues.

What is the biological process in which a single cell divides into two individual cells?

Cytokinesis occurs when single-cell organisms reproduce to form two organisms and with embryos during development. Plant and animal matter also undergo cytokinesis during growth and repair processes.

21 of 35
What is the name of the instrument used to measure atmospheric pressure?

Barometers also measure altitude since atmospheric pressure changes depending on the distance below or above sea level. Aneroid and mercury are the two main types of barometers.

22 of 35
What is a group of stars that form a recognizable pattern called?

Constellation patterns assist astronomers in locating certain stars or other celestial objects. Asterisms are the smaller groups of stars that comprise the larger constellation.
