This beautiful cosmic purple galaxy composition notebook features an image from NASA's Hubble Telescope of the Arches Cluster. Whether you're an astronomy buff or just love the colors, this is a beautiful notebook. Cornell Notes, also referred to as Two-Column Notes, are a great way to organize your notes for class. Use the left column for topics and main ideas, the right column for supporting details (words, diagrams, images, etc.), and then summarize the information at the bottom. This is a great research-based strategy for effective note taking.
