In this activity students will calculate the rate of the movement of Pacific Tectonic plate by examinining the formation of Hawaiian island chain. Students begin by determining ages of rocks found on each island using radiometric dating principle. Then they use scale maps to determine real world distances between islands. Finally they determine speed of motion from distance and time passed.
This lab utilizes the claim, evidence and reasoning framework to guide students to synthesis of ideas and paragraphing.
I includede a scaffolded claims/evidence/reasoning framework for beginners and also unscaffolded for proficient students. Rubric is also included.
HS-ESS1-5. Evaluate evidence of the past and current movements of continental and oceanic crust and the theory of plate tectonics to explain the ages of crustal rocks.
HS-ESS2-1. Develop a model to illustrate how Earth’s internal and surface processes operate at different spatial and temporal scales to form continental and ocean-floor features.
