    What remains the same in an object on the moon?                                                                    

    • A.

      Weight

    • B.

      Material

    • C.

      Mass

    • D.

      Energy

  • 3. 

    What kind of change in matter produces new substances, such as a burning match?                                    

    • A.

      Physical change

    • B.

      Observable change

    • C.

      Chemical change

    • D.

      Amorphous solid

    Correct Answer
    C. Chemical change
    Explanation
    A burning match undergoes a chemical change. In a chemical change, the composition of the matter is altered, resulting in the formation of new substances. When a match burns, the reactants (the matchstick and oxygen from the air) undergo a chemical reaction, which produces new substances such as carbon dioxide, water vapor, and ash. This change is not reversible, and the properties of the original substances are permanently altered. Therefore, a burning match is an example of a chemical change.

  • 4. 

    Which weighs more, a kilogram of chicken or a kilogram of feathers?                             

    • A.

      Chicken weighs more the feathers

    • B.

      Feathers weigh less than the chicken

    • C.

      Chicken and feathers weigh the same

    • D.

      Feathers weigh more than the chicken

    Correct Answer
    C. Chicken and feathers weigh the same
    Explanation
    The correct answer is that chicken and feathers weigh the same. This is because both a kilogram of chicken and a kilogram of feathers have the same weight, which is one kilogram. The question is a play on words, as it tricks the reader into thinking that the feathers would weigh less due to their lighter and fluffier nature compared to the solid mass of the chicken. However, weight is determined by the mass of an object, and in this case, both the chicken and the feathers have the same mass of one kilogram.

  • 5. 

    What is amount of the measurement on the meter stick, which is located at the letter F? (Remember each black mark is 1/10 or or 0.1 after you read the whole number).                                        

    • A.

      5.0 in.

    • B.

      4.9 in.

    • C.

      4.9 cm

    • D.

      4.9 mL

    Correct Answer
    C. 4.9 cm
    Explanation
    The correct answer is 4.9 cm because the question asks for the measurement on the meter stick at the letter F. The other options (5.0 in., 4.9 in., 4.9 mL) are not relevant to the meter stick measurement. The given answer matches the unit of measurement specified in the question (cm) and is the closest measurement to the letter F on the meter stick.

  • 6. 

    Who invented the idea of gravity when an apple fell off a tree?              

    • A.

      Galileo

    • B.

      Newton

    • C.

      Charles

    • D.

      Boyle

    Correct Answer
    B. Newton
    Explanation
    Newton is the correct answer because he is credited with formulating the concept of gravity when an apple fell off a tree. This event is said to have inspired Newton to develop his theory of universal gravitation, which states that every object in the universe attracts every other object with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them. Newton's work on gravity revolutionized our understanding of the physical world and laid the foundation for modern physics.

    Two or more substances that are mixed together but not chemically combined are called a mixture. In a mixture, the substances retain their individual properties and can be separated by physical means. This is different from a compound, where two or more elements are chemically combined to form a new substance with different properties.

    What is the absorbing of energy in the form of heat, such as an ice pack absorbing energy, resulting the drop in temperature?                                                                       

    • A.

      Chemical reaction

    • B.

      Exothermic reaction

    • C.

      Endothermic reaction

    • D.

      Nuclear reaction

    Correct Answer
    C. Endothermic reaction
    Explanation
    An endothermic reaction is a chemical reaction that absorbs energy in the form of heat from its surroundings. When an ice pack absorbs energy, it takes in heat from its surroundings, resulting in a drop in temperature. This is an example of an endothermic reaction because the ice pack is absorbing energy (heat) from its surroundings.
