Pearson Science Year 7 Quiz! - Quiz

The study of science, when you consider all of the incredible discoveries that have come out of it, is arguably the most fabulous journey humankind has ever embarked upon. It has allowed us to come to grips with more than what the naked eye can see and put into perspective where we are in the universe, what the universe even is and how exactly we got here. What can you tell us about science from a Year 7 perspective?


Questions and Answers
  • 1. 

    Energy is...

    • A.

      Anything at moves.

    • B.

      The ability to do work.

    • C.

      Unable to be seen.

    • D.

      Able to be created

    Correct Answer
    B. The ability to do work.
    Explanation
    Energy is defined as the ability to do work. In physics, work is defined as the transfer of energy from one object to another, or the transformation of energy from one form to another. Energy is not limited to just the ability to move, as it encompasses various forms such as mechanical, thermal, electrical, and chemical energy. 

    Rate this question:

  • 2. 

    Which action involves the greatest amount of potential energy?

    • A.

      Running fast

    • B.

      Standing on a diving board

    • C.

      Running slow

    • D.

      Sleeping

    Correct Answer
    B. Standing on a diving board
    Explanation
    Standing on a diving board involves the greatest amount of potential energy. Potential energy is related to an object's position or height above the ground; therefore, standing on a diving board, which is elevated, results in higher potential energy compared to the other options listed.

    Rate this question:

  • 3. 

    An object that has kinetic energy must be...   

    • A.

      Elevated.

    • B.

      In motion.

    • C.

      At rest.

    • D.

      Upside down.

    Correct Answer
    B. In motion.
    Explanation
    An object that has kinetic energy must be in motion. Kinetic energy is the energy possessed by an object due to its motion. When an object is in motion, it has the ability to do work. If the object is at rest, it does not possess kinetic energy. Being elevated or upside down does not necessarily determine whether an object has kinetic energy or not.

    Rate this question:

  • 4. 

    Sound energy is...   

    • A.

      The energy of a compound that changes as the atoms are rearranged to form new compounds.

    • B.

      The total energy of the particles that make up an object.

    • C.

      The energy caused by an object's vibrations.

    • D.

      The energy of motion

    Correct Answer
    C. The energy caused by an object's vibrations.
    Explanation
    Sound energy is the energy caused by an object's vibrations. When an object vibrates, it creates sound waves which travel through a medium, such as air or water. These vibrations transfer energy in the form of sound waves, which can then be detected by our ears. Sound energy is a type of kinetic energy, as it involves the movement of particles in the medium. It is distinct from other forms of energy, such as potential energy or thermal energy, as it specifically refers to the energy associated with vibrations and the transmission of sound waves.

  • 5. 

    Fill in the blanks....The law of                         of energy states that energy can not be                              or                                        . 

    • A.

      Properties, seen, heard.

    • B.

      Conservation, created, destroyed.

    • C.

      Conservation, created, discovered.

    • D.

      Properties, felt, smelt.

    Correct Answer
    B. Conservation, created, destroyed.
    Explanation
    The law of conservation of energy states that energy cannot be created or destroyed. This means that the total amount of energy in a closed system remains constant. While energy can change forms or be transferred from one object to another, it cannot be completely lost or gained. This principle is a fundamental concept in physics and is supported by numerous scientific experiments and observations.

    Rate this question:

  • 6. 

    Where would you feel the heaviest? 

    • A.

      Walking on the moon

    • B.

      Walking on the earth

    • C.

      Swimming in a pool

    • D.

      Sitting in a satellite

    Correct Answer
    B. Walking on the earth
    Explanation
    Walking on the earth would make you feel the heaviest because the earth has the greatest gravitational pull that attracts objects towards its center. This gravitational force is responsible for giving objects weight. When you are standing on the earth's surface, you are being pulled towards its center, resulting in a feeling of heaviness. In contrast, the moon has a much weaker gravitational pull, so you would feel lighter while walking on its surface. Swimming in a pool or sitting in a satellite would not have the same gravitational force as walking on the earth, so you would not feel as heavy in those situations.

    Electricity can only flow through a circuit if it is....

    • A.

      Completed

    • B.

      Simple

    • C.

      Open

    • D.

      Closed

    Correct Answer
    D. Closed
    Explanation
    Electricity can only flow through a circuit if it is "closed". A closed circuit means that there is a complete path for the electricity to flow, with no breaks or interruptions. When a circuit is closed, the electrical current can move freely from the power source to the load and back again. This allows for the continuous flow of electricity and the operation of electrical devices. On the other hand, if a circuit is open, there is a break in the path, and electricity cannot flow through it. Therefore, a closed circuit is necessary for the flow of electricity.

    Look at the picture... When electricity is turned on, which of the following is produced?

    • A.

      Thermal energy

    • B.

      Magnetic force

    • C.

      Light energy

    • D.

      Sound energy

    Correct Answer
    B. Magnetic force
    Explanation
    When electricity is turned on, it produces a magnetic force. This is because electric current flowing through a wire creates a magnetic field around it. The strength of the magnetic force depends on the amount of current flowing through the wire. This phenomenon is utilized in various electrical devices such as motors and generators, where the interaction between electricity and magnetism is used to produce mechanical energy or generate electricity.

    A student is playing guitar. Some of the strings vibrate more quickly than the other string. What effect does this have on the sound?

    • A.

      The faster vibrating strings make louder sounds.

    • B.

      The faster vibrating strings make lower sounds.

    • C.

      The faster vibrating strings make soft sounds.

    • D.

      The faster vibrating strings make higher sounds.

    Correct Answer
    D. The faster vibrating strings make higher sounds.
    Explanation
    When the strings of a guitar vibrate more quickly, they produce a higher frequency of sound waves. Higher frequency sound waves are perceived as higher-pitched sounds.

    We use the term                      to describe forces acting at a distance.

    • A.

      'motion'

    • B.

      'field'

    • C.

      'photosynthesis'

    • D.

      'running'

    Correct Answer
    B. 'field'
    Explanation
    The term "field" is used to describe forces acting at a distance. In physics, a field is a physical quantity that exists throughout space and can exert a force on objects within its influence. Examples of fields include gravitational fields, electric fields, and magnetic fields. These fields can act on objects without direct contact, demonstrating the concept of forces acting at a distance.
