Students 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?
