After the Storm

A survey of the school grounds the morning after a gale, with the weather record for that week. THE WEEK AND THE DAMAGE Mon-Thu: light wind, no damage Friday: gale, gusts to 70 mph Damage: 3 fence panels down, 1 tree branch broken, bins across the yard The bins in the sheltered corner did not move. The fence on the sheltered side did not fall.

  1. 1. What claim does this survey support?
  2. 2. Why did the sheltered fence stay up?
2.A design works in a light gale but not a severe one. What should you say?
  • A.It works perfectly
  • B.It reduces some damage but not all, and say at what strength it fails
  • C.It does not work
3.Lightning rods on a school. What hazard do they reduce?
  • A.Damage and fire from a lightning strike
  • B.Flooding
  • C.Strong wind
4.A flood barrier protects one street and floods the next. How do you judge it?
  • A.Only count the street it saved
  • B.Count the harm it moves as well as the harm it stops
  • C.Ignore the second street
5.Why can no design remove a weather hazard completely?
  • A.Designs are always poor
  • B.Weather never repeats
  • C.Weather can always be more severe than a design was built for
6.What should a claim about a design's merit include?
  • A.Only how it looks
  • B.Evidence of what it reduced, and what it cost
  • C.Only what it cost
7.Which evidence would best judge a windbreak?
  • A.Damage before and after it was built, in similar gales
  • B.How tall it is
  • C.Its colour

Answer key — Is That Design Worth It?

Set 24. Prints on its own sheet.

  1. 1.1. Shelter reduces the damage a gale does. 2. It was out of the gale, so less wind pushed on it.
  2. 2.It reduces some damage but not all, and say at what strength it fails
  3. 3.Damage and fire from a lightning strike
  4. 4.Count the harm it moves as well as the harm it stops
  5. 5.Weather can always be more severe than a design was built for
  6. 6.Evidence of what it reduced, and what it cost
  7. 7.Damage before and after it was built, in similar gales
