In Health, students have been learning about ice safety. Students learned:
  • Ice should be at least 10cm of clear solid ice and the only way to tell is drill a hole in the ice (best to check ice conditions with local ice hut operators).
  • You cannot tell the strength of ice by the appearance alone.
  • What to do if they are someone else falls through the ice.
  • What to do if you fall through the ice.
  • Warning signs that ice might be weak (pressure cracks, spider cracks, slush)
