Description
Product Details
- Explore emerging energies while designing a waterwheel to compete with other teams in producing the most effective design.
- High school engineering design challenge with enough materials to support 8 groups of students.
- Carolina Kits 3D®—Lab activity that designs a solution for an engineering problem to support NGSS and 3-dimensional instruction.
In this series of activities, students apply their knowledge of energy and energy transformations to solve an engineering problem, “How can we improve the design of a hydroelectric power system to maximize output?” During the research activity, students observe a hand generator and discuss the energy transformations that occur; then they relate the demonstration to a hydroelectric power system. Student teams are challenged to design and build a device that uses the energy of falling water to turn an axle and lift a paper clip (as a model for generating electricity).
Students refine their design, attempting to design the device that lifts the paper clip highest using 100 mL of water. Rubrics, assessment questions, and STEM-based extension activities also are included.

Learning Objectives
- Design a waterwheel as a model of a hydroelectric power generator.
- Evaluate how the structure and function of the model affect its performance and identify ways the model can be improved.
- Understand the benefits of hydroelectric power to society and the environment.
Prior Knowledge and Skills
Students should be familiar with different types of energy, including gravitational potential energy, kinetic energy (including mechanical), and electrical energy. They should also understand energy transformations and renewable energy resources.
