    A quantitative observation involves conditions that can be 

    • Measured

    • Heard

    • Felt

    • Tasted

    Correct Answer
    A. Measured
    Explanation
    A quantitative observation involves conditions that can be measured. This means that it involves collecting data or information that can be expressed numerically or in terms of quantity. It focuses on obtaining precise measurements or values, such as length, weight, temperature, or time. This type of observation allows for objective analysis and comparison of different variables or phenomena.

    Which of the following statements is true?

    • Chemicals are always toxic

    • Chemicals are always dangerous

    • All chemicals are safe

    • Everything made of matter is a chemical.

    Correct Answer
    A. Everything made of matter is a chemical.
    Explanation
    The correct answer is "Everything made of matter is a chemical." This statement is true because all matter, whether it is natural or man-made, is made up of chemicals. Chemicals are the building blocks of matter and can be found in everything around us, including the air we breathe, the water we drink, and the food we eat. Therefore, everything that exists in the physical world is composed of chemicals, making this statement true.

    From the l labs we have done the past few days we know that  ...

    • Some matter dissolves in water and some does not

    • Some matter is mixtures of different substances

    • Some mixtures can be separated

    • All given answers are correct

    Correct Answer
    A. All given answers are correct
    Explanation
    The statement "all given answers are correct" is a valid explanation because it summarizes the information provided in the question. The question states that from the labs done in the past few days, it has been observed that some matter dissolves in water and some does not, some matter is mixtures of different substances, and some mixtures can be separated. Therefore, all of the given answers are correct as they align with the observations made in the labs.

    What should you put on the your paper in your science notebook everyday

    • Date

    • A compliment for Ms. Brown

    • Ten elements from te periodic table

    • One safety rule

    Correct Answer
    A. Date
    Explanation
    The correct answer is "date." It is important to put the date on your paper in your science notebook every day to keep track of when the information was recorded. This helps in organizing and referencing the notes later on.

    Which of the following would be a qualitative observation?

    • It is blue.

    • It is 5 cm long.

    • It is 12.3 g.

    • I like the color.

    Correct Answer
    A. It is blue.
    Explanation
    A qualitative observation is a subjective description that does not involve any numerical measurements. In this case, "it is blue" is a qualitative observation because it describes the color of the object without providing any specific measurements or quantities.

    The space that matter takes up is its

    • Volume

    • Mass

    • Weight

    • Density

    Correct Answer
    A. Volume
    Explanation
    Volume refers to the amount of space that an object occupies. It is a measure of the three-dimensional extent of an object. Mass, weight, and density are all related to the physical properties of matter, but they do not directly indicate the space that matter takes up. Therefore, volume is the correct answer in this context.

    • The building blocks of everything in the universe

    • Some of the elements in the world

    • All of the naturally occurring elements

    • All natural compounds

    Correct Answer
    A. The building blocks of everything in the universe
    Explanation
    The periodic table is a systematic arrangement of all the known elements in the universe. It provides a comprehensive overview of the fundamental building blocks that make up everything in the universe, including both natural elements and their compounds. By organizing the elements based on their atomic number, properties, and electron configurations, the periodic table allows scientists to study and understand the relationships and patterns among different elements, enabling further exploration and discovery in various fields of science.
