Tidal Tales: Moon's Grip and Ocean Tides

Grade 7Science10 days
This project explores the moon's gravitational pull and its impact on Earth's tides. Students investigate different types of tides, analyze tidal data, and consider the effects of tides on coastal communities and ecosystems. Through research, data analysis, and multimedia presentations, students develop a deeper understanding of the complex relationship between the moon, Earth, and the ocean.
