Comparing Rocks with Double Bubble Maps

The video tutorial guides students on how to compare rocks using a double bubble map. It outlines the learning goals, which include observing, describing, and comparing rocks by size, texture, and color. Students are instructed to choose two rocks from a chart, compare them using various properties, and draw them. The tutorial emphasizes using inner circles for similarities and outer circles for differences. Finally, students are asked to take a picture of their work and share it in a class discussion.

What is the main goal of the lesson on comparing rocks?
