Part of our Rock Lessons included making and baking SEDIMENTARY ROCK SNACKS! This was all in the name of science! This was an easy baking lesson that we did as an entire class. I greatly enjoyed this with the kids and would sooo do this with my students. It was helpful to have three teachers helping three groups of kids with measuring and layering our glass pans.
THANK YOU, MRS. LACHER, FOR THE RECIPE!!!
Ingredients for one pan:
1/2 cup of butter
1 & 1/2 cups of vanilla wafers crumbs
1 can of condensed milk
1 package of peanut butter chips
(can substitute with other chips and/or craisins if there are peanut allegies or add for extra 'rocks')
1 cup of chopped nuts (optional)
Materials:
clear/glass 13" by 9" baking pan (may need more than one depending on number of students)
can opener
rolling pin (optional)
Freezer Ziploc bags (use one bag for each group of students)
several measuring cups
(light enough for kids to use to layer indegredients)
heat source
oven mitts
Steps to Follow:
1. Crush vanilla wafers in freezer Ziploc bag (use rolling pin and/or have kids use fists to crush)
2. Melt butter and pour in pan
3. Sprinkle vanilla wafer crumbs over melted butter
4. Pour condensed milk evenly over the crumbs
5. Layer the remaining ingredients evenly over the top
6. Press down gently (use spoon or spatula)
7. Bake at 350 degrees F for 25-30 minutes
8. Let cool...cut into bars...ENJOY!
Follow-up with Students:
Describe how the baked item was formed. Notice that after being pressed and exposed to heat (baked), the items remained in layers. Explain how this is a good example of how sedimentary rocks were formed.
