Geology Lesson for Lunch

Geology for LunchStudents of the 6-8 team recently made appetizing (?) visuals to increase their understanding of the earth’s multi-layered crust.

With the help of Mr. Kennedy and Mr. Loar, students constructed sandwiches from the bottom up with the following layers:

  • paper plate
  • white bread slice
  • crunchy peanut butter and raisins
  • grape jelly
  • strawberry jelly
  • wheat bread slice
  • creamy peanut butter with gummy bears
  • rye bread slice

But what does all of this represent?

  • paper plate – bedrock
  • white bread slice – white sandstone formed when a river flows over bedrock
  • crunchy peanut butter with raisins – conglomerate resulting from a storm or flood; (crunchy peanut butter represents mud and rocks, and the raisins represent big boulders trapped in the rushing waters)
  • grape jelly – oil
  • strawberry jelly – natural gas
  • wheat bread slice – shale, (soft, sedimentary rock formed from consolidated mud or clay)
  • creamy peanut butter with gummy bears – limestone with fossils
  • rye bread slice – brown sandstone, formed when pieces of rocks are embedded after a drought

The activity led to interesting questions and conversations about weathering, erosion, fracking, and other topics.

What hands-on activity will Mr. Kennedy and Mr. Loar use next to educate and inspire?
