  1. Which gas do humans exhale in greater amounts compared to what they inhale?

    Answer: Carbon dioxide

    During cellular respiration, the body converts oxygen and glucose into energy, releasing carbon dioxide as a waste product that is exhaled.

  2. A thermometer measures temperature in degrees Celsius. If water starts to boil at 100°C, what is the equivalent in Fahrenheit?

    Answer: 212°F

    Water boils at 100°C, which is equivalent to 212°F, using the conversion formula F = (C × 9/5) + 32.

  3. Fossils are most commonly found in which type of rock?

    Answer: Sedimentary

    Sedimentary rocks form from layers of sediment that can trap and preserve the remains of organisms, creating fossils.

  4. During a solar eclipse, what is happening?

    Answer: The Moon passes between Earth and the Sun

    A solar eclipse occurs when the Moon passes between Earth and the Sun, temporarily blocking sunlight from reaching parts of Earth's surface.

  5. Which characteristic do all living things share?

    Answer: They are made of cells

    All living organisms — from bacteria to plants to animals — are composed of one or more cells, the basic unit of life.

  6. A flashlight beam appears to travel in a straight line. This property of light is called:

    Answer: Rectilinear propagation

    Rectilinear propagation means that light travels in straight lines unless it is reflected, refracted, or diffracted.

  7. Which of the following best explains why metal spoons get hot when left in a hot pot of soup?

    Answer: Conduction of heat through the metal

    Metals are good conductors of heat; thermal energy transfers from the hot soup through the metal spoon by conduction.
