Goosebumps

Thomas and Keith were playing with fireworks. It
appeared as though the fuse didn’t light on one of
The fireworks, so Keith picked it up to investigate.
The firework went off in his hand and Keith got
severely burned.

Label types of burns, skin affected, and characteristics

• First-Degree (Superficial):
  • Affects only the outer layer (epidermis).
  • Looks like a bad sunburn: red, painful, maybe some swelling.
  • Heals quickly without scarring.
• Second-Degree (Partial Thickness):
  • Damages the epidermis and the layer beneath (dermis).
  • Causes intense pain, redness, swelling, and fluid-filled blisters.
  • Can be superficial or deep, potentially requiring surgery.
• Third-Degree (Full Thickness):
  • Burns through all skin layers into fatty tissue, sometimes muscle or bone.
  • Appearance: leathery, dry, white, brown, or black; doesn't blanch (turn white) when pressed.
  • Often painless because nerves are destroyed.
  • Requires immediate hospital care; skin grafts are often necessary for large burns.
