Are You Ready To Take The Ultimate Science Challenge Quiz? - Quiz

Science is a fun subject and gives us a clear understanding of the universe and what exists on and in it. When a new discovery is made, it opens people to new knowledge. Take up the exciting quiz below and see how knowledgeable you are when it comes to science.


Questions and Answers
  • 1. 

    Scientists have found only 2 substances in the whole universe. What are they?

    • A.

      Matter and Air

    • B.

      Oxygen and Mass

    • C.

      Matter and Energy

    Correct Answer
    C. Matter and Energy
    Explanation
    The correct answer is Matter and Energy. Scientists have discovered that the universe is composed of matter, which includes all physical substances, and energy, which is the capacity to do work or cause change. These two fundamental entities are found throughout the entire universe, making them the only known substances.

    Who is was the scientist that explained gravity and motion?

    • A.

      Isaac Newton

    • B.

      Albert Eienstien

    • C.

      Ben Franklin

    Correct Answer
    A. Isaac Newton
    Explanation
    Isaac Newton is the correct answer because he is the scientist who explained gravity and motion. He formulated the laws of motion and the law of universal gravitation, which have been fundamental in understanding the behavior of objects in motion and the force of gravity. Newton's contributions to the field of physics revolutionized our understanding of the natural world and laid the foundation for modern physics.

    What is the label for the volume of solids?

    • A.

      Liters

    • B.

      Cm3

    • C.

      Grams

    Correct Answer
    B. Cm3
    Explanation
    The label for the volume of solids is cm3. This unit, also known as cubic centimeters, is commonly used to measure the volume of three-dimensional objects. It represents the amount of space occupied by a solid and is derived from the cubic measurement of length. Liters and grams are not appropriate labels for the volume of solids as they are typically used to measure liquids and mass, respectively.

    What happens in order to move objects?

    • A.

      Another substance is displaced.

    • B.

      The air doesn't move with it.

    • C.

      The object doesn't move.

    Correct Answer
    A. Another substance is displaced.
    Explanation
    When objects are moved, another substance is displaced. This means that when an object is moved from one place to another, it pushes aside or displaces another substance that was occupying that space. This displacement of another substance allows the object to occupy the new space, causing it to move.

    How long is a day?

    • A.

      24 hours

    • B.

      23 hours and 56 minutes

    • C.

      23 hours and 57 minutes

    Correct Answer
    B. 23 hours and 56 minutes
    Explanation
    A day is defined as the time it takes for the Earth to complete one full rotation on its axis. This rotation takes approximately 23 hours and 56 minutes. This is slightly shorter than a 24-hour day, which is why we have leap years and leap seconds to account for the small discrepancy.

    Rate this question:

  • 6. 

    How long is a year?

    • A.

      364 days and 1/4 day

    • B.

      365 days

    • C.

      365 days and 1/4 day

    Correct Answer
    C. 365 days and 1/4 day
    Explanation
    A year is typically defined as the time it takes for the Earth to complete one orbit around the Sun. However, this orbit is not exactly 365 days long. It actually takes about 365 days and 6 hours. To account for this extra time, we add an extra day to the calendar every four years, creating a leap year. This extra day, known as February 29th, helps to keep our calendar in sync with the Earth's orbit. So, the correct answer is 365 days and 1/4 day, as it accounts for the additional 6 hours in a year.

    • E.

      15

    Correct Answer
    B. 8
    Explanation
    There are 8 planets in our solar system. This includes Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. These planets orbit around the Sun and are part of our solar system.

    Does moon have gravity?

    • A.

      Yes

    • B.

      No

    Correct Answer
    A. Yes
    Explanation
    The moon does have gravity. Although it is much weaker than Earth's gravity, it still has enough force to keep objects and astronauts on its surface. This is why astronauts can walk and jump on the moon, and why the moon is able to orbit around the Earth. Gravity is a fundamental force of nature that exists between all objects with mass, and the moon, despite its smaller size, is no exception.

    Study of living organisms come under:

    • A.

      Chemistry

    • B.

      Physics

    • C.

      Biology

    Correct Answer
    C. Biology
    Explanation
    The study of living organisms falls under the field of biology. Biology is the scientific discipline that focuses on the study of living organisms, including their structure, function, growth, evolution, and distribution. It encompasses various sub-disciplines such as botany, zoology, microbiology, and genetics, among others. Chemistry deals with the composition, properties, and reactions of substances, while physics focuses on the fundamental principles of matter and energy. Therefore, the correct answer is biology.

    How many laws of gravity has Newton given?

    • A.

      2

    • B.

      3

    • C.

      4

    • D.

      5

    Correct Answer
    B. 3
    Explanation
    Newton has given three laws of gravity. These laws are known as Newton's laws of motion and they describe the behavior of objects under the influence of gravitational forces. The laws state that objects at rest will remain at rest unless acted upon by a force (first law), the force acting on an object is equal to its mass times its acceleration (second law), and for every action, there is an equal and opposite reaction (third law). Therefore, the correct answer is 3.
