This 4-day lesson plan teaches 3rd grade students about dolphins and their habitats. Each day focuses on a different activity to learn facts about dolphin species: day 1 has students research online and in the library to create a concept map, day 2 uses Google Maps to locate species locations, day 3 involves reading a story and answering questions, and day 4's final assessment asks students to write and draw about what they learned. The lesson incorporates various subjects and teaches research skills using technology and other online resources.
