How is the behavior of food coloring in the cool and heated water different? What caused the differences in their behavior?
In the cool water, the food coloring stayed at the bottom of the container with very little movement. In the heated water, the food coloring rose to the top, spread to the sides, and then sank back down. This difference is caused by convection currents; the heat source makes the water at the bottom less dense, causing it to rise, while the cooler, denser water at the top sinks.

How did the lab activities help you answer the lesson question: What effect does plate movement have on geologic events and structures at Earth’s surface? What did you learn from conducting this lab?
The lab activities demonstrated that the movement of Earth’s plates is driven by convection currents in the mantle. I learned that different types of plate boundaries result in different geologic events and structures. For instance, divergent boundaries form new crust, convergent boundaries produce volcanoes and mountains, and transform boundaries cause earthquakes. These processes constantly reshape the Earth’s surface.
