An example of an appropriate playground surfacing material is: A. Grass B. Mulch C. Dirt

Answer: B. Mulch

Explanation: The question is about selecting an appropriate playground surfacing material. The key consideration for playground surfaces is safety, particularly in terms of cushioning falls to prevent injuries. Mulch is commonly used in playgrounds because it provides a soft surface that can absorb impact, reducing the risk of injury.

Steps:

  1. Identify the options:
  • A. Grass
  • B. Mulch
  • C. Dirt
  1. Evaluate each option:
  • Grass: While it is soft, it can become slippery when wet and may not provide sufficient cushioning for falls.
  • Mulch: Provides a soft, impact-absorbing surface, making it suitable for playgrounds.
  • Dirt: Can become compacted and hard, offering little cushioning and increasing the risk of injury.
  1. Select the best option: Based on safety and impact absorption, mulch is the most appropriate choice for playground surfacing.
