About This Quiz

We learn quite a bit about the various sciences during our schooling. Even when you get to college, you have to take at least two science courses to fill prerequisites, regardless of your major. Knowing the fundamentals of science can help you throughout your everyday life. If you know that every action has an equal and opposite reaction, you know what's happening when your cat knocks something off the counter for fun. You may even know that ice is the solid form of water molecules, but we may ask you why it floats.

You don't necessarily have to be a science whiz or a person full of "useless" facts to pass this quiz, but you may have to remember a few things from grade school. We're going across the scientific board here. There will be questions on everything from Earth science to physics, with a little biology thrown in there as well. 

If you think you have the basics of science down, you might not have a problem acing this quiz. But can you do it in less than seven minutes? The pressure is on, and the clock is ticking. Let's see how fast you can answer these basic science questions.

1. pluto Pluto is no longer considered a planet. What is its classification now?
Super planet
Frozen planet
Dwarf planet
Those of us who grew up learning that Pluto was the ninth planet in our solar system were shocked to learn that it was going to be knocked down a classification. However, the size and functionality of the ball of ice proves that it shouldn't be considered a planet at all.

2. shark About how many bones are in a shark's body?
None
There are no bones in a shark's body. As a matter of fact, the majority of a shark's structure comes from cartilage. Though it lightens up the shark, it makes studying ancient sharks very difficult, as there are few remains.
Seven
247

3. earth What is the Earth's core made of?
Water
The Earth doesn't have a core.
Oxygen and hydrogen
Nickel and iron
Scientists estimate that the core of the Earth is made out of a nickel-iron alloy that is so hot, it is in a liquid state. This dense, hot core has been there since the Earth was first made. While the surface of the planet has cooled, the core has not.

5. cater Do you know what stage of life a caterpillar is considered to be?
Egg
Larva
The stages of insects are all a little different. However, we all know that caterpillars turn into butterflies, but the stage of life when they're worm-like (caterpillars) is called the larva stage. When they're in transition, its the pupa stage, and when they're butterflies, they're in the adult or reproductive stage.
Egg

7. heart Which part of the body is responsible for pumping blood to your major organs?
The lungs
The liver
The brain
The heart
Of the vital organs (organs that are necessary for life), the heart is the one that pumps blood to every other organ in your body. This allows your body to disperse oxygen to sustain life and health.

10. dad Which parent's gene creates a baby's gender?
Both parents
Mother
Father
A father's sex cells (sperm) carry the X or Y chromosome that determines a baby's gender. However, recent studies have shown that sexual mutations (that's the scientific term) are more common than we once thought, giving multiple X chromosomes to children. These often go unnoticed (physically).
Genes don't determine gender.

23. freze At what temperature does water freeze?
0 degrees Centigrade
In Centigrade, water freezes at 0 degrees. However, in Fahrenheit, it freezes at 32 degrees. Once water freezes, it changes from its liquid form to its solid form. it also expands.

24. float Why does frozen water float?
It's heavier than its liquid form.
It expands and becomes less dense.
Frozen water (ice) is around 9% less dense than water in its liquid form. As the water expands, it becomes lighter by area, making it float above liquid water. If frozen water didn't float, the Earth would be mostly frozen over.
It doesn't float.
There is no explanation.
