  1. A graph of a bouncing ball shows its height after each bounce: 100 cm, 60 cm, 36 cm, 21.6 cm. What pattern does this data show?

    Answer: Height decreases by 40% each bounce

    Each successive height is 60% of the previous (losing 40%), showing an exponential decay pattern.

  2. An experiment grows bacteria in a dish. After 1 hour there are 100 bacteria, after 2 hours there are 200, after 3 hours there are 400. How many bacteria would you predict after 4 hours?

    Answer: 800

    The count doubles each hour, so after 4 hours: 400 × 2 = 800 bacteria.

  3. A Venn diagram compares mammals and birds. The overlapping section contains 'warm-blooded.' What does the overlapping section represent?

    Answer: Traits shared by both groups

    The overlapping section of a Venn diagram always represents characteristics shared by both groups.

  4. A student records the following masses for five trials of the same experiment: 12.1 g, 12.3 g, 11.9 g, 12.2 g, 12.0 g. What is the mean mass?

    Answer: 12.1 g

    Sum = 60.5 g; mean = 60.5 ÷ 5 = 12.1 g.

  5. A thermometer shows temperature rising steadily for 5 minutes, then rising more steeply for the next 5 minutes. What does the steeper slope indicate?

    Answer: Temperature is rising faster

    A steeper slope on a temperature-time graph indicates a faster rate of temperature increase.

  6. Scientists studying a lake record average fish populations each year for 10 years. They notice a sharp decline in Year 6. Which factor would best explain this anomaly?

    Answer: A pollution event or disease outbreak in Year 6

    A sudden sharp decline suggests an environmental disruption such as pollution or disease rather than gradual natural change.

  7. An experiment tests three brands of paper towels by measuring how much water each absorbs. Brand X absorbs 120 mL, Brand Y absorbs 95 mL, Brand Z absorbs 110 mL. Which towel is most absorbent?

    Answer: Brand X

    Brand X absorbed the most water at 120 mL, making it the most absorbent.
