Science Content:
Summarize the processes that shape the Earth's surface and describe evidence of those processes.
Observe and describe the composition of soil, investigate that soils are often found in layers
Organize and evaluate observations, measurements and other data to formulate inferences and conclusions
Use skills of scientific inquiry processes
Estimated Time: Part 1- 30 minute class period Part 2- One class period to collect samples and one class period to analyze samples
During this activity students will gain and understanding of what is under Earth's surface using a cupcake as a simulation of the layers of soil. This is followed by an activity where students will collect soil samples from around the school and look for similarities and differences.
Part 1: Students will discuss weathering and look at examples of rocks that have changed over time. They will then use tools and a cupcake to perform a simulation of taking a core sample and using this sample to draw the layers of the cupcake. Students will discuss their findings and how these compare to the work a geologist performs.
Part 2: Students will work to take soil samples from around their schoolyard. They will then use these samples to compare similarities and differences throughout the soil at their school.
