DIY Wave Tank: Exploring Ocean Currents

Grade 8Science5 days
The 'DIY Wave Tank: Exploring Ocean Currents' project engages 8th-grade students in designing and constructing a functional wave tank to explore the effects of thermal energy on ocean currents and their subsequent impact on global climate patterns. Through hands-on experimentation and data analysis, students learn how thermal-energy transfers influence ocean currents, the role of the sun's energy and gravity in water movement, and apply engineering design skills to refine their models. The project connects classroom learning to real-world climate scenarios, promoting critical thinking and collaborative problem-solving skills.
