This STEM Challenge is inspired by a geology class I'm teaching for kindergarten - 2nd grade homeschoolers in our area. Last week we learned about sedimentary rocks, and I realized my plans for a model could easily be adapted to a STEM activity that kids of all ages (from preschoolers to adults) would love!
The Challenge: Create an edible sedimentary rock model!
You could use so many different supplies, but here is what I provided:
How does this line up with STEM?
SCIENCE:
** Pressure from smashing the edible sedimentary rock forces the candies and cookie pieces into the marshmallow while lowerimg the melting point of the marshmallow. The marshmallow then sticks everything together!
** We also covered the science behind sedimentary rock formation before the modeling activity. You could also do it in this order, or you could discuss how sedimentary rocks are formed at the same time as you make the models. Either way, I had large samples of sedimentary rocks for the kids to look at, touch, and investigate. We talked about these points:
1- Sedimentary rocks are made by smashing or sticking rocks and minerals together.
2- Earth’s history is stored in layers of sedimentary rocks. Most fossils are contained in sedimentary rock.
3- Common sedimentary rocks (these are the samples I brought): sandstone, shale, breccia, conglomerate, limestone, iron ore, fossiliferous limestone, coal
4- Quartz and calcite are minerals that often "glue" sedimentary rocks together
TECHNOLOGY: You could let your kids use tools to smash their sedimentary rocks together, take pictures of their rocks, or make a video of the process!
ENGINEERING: Designing and creating a model.
MATH: There are loads of options to add a math component to this project! You could have your kids research how old the sedimentary rocks are in your area (oops...that's math and technology!), have them calculate how much their edible sedimentary rock cost, make a giant pie-sized edible sedimentary rock and cut it into fractions, or something else! I'd love to know how you add math to this activity!
This activity goes great with my book A Dinosaur Made Me Sneeze: A Rock Cycle Adventure!

M&M's, mini marshmallows, graham crackers, and cupcake liners.

This activity goes great with my book A Dinosaur Made Me Sneeze: A Rock Cycle Adventure!
This book introduces the rock cycle and three types of rocks with a hilarious story that kids of all ages are loving! It's been a huge hit with audiences from preschoolers all the way up through high school! You can get it on Amazon or Turtle Trails Publishing!
