Heating Systems Comparison: Choosing the Best for Our School

Grade 6Science5 days

In this project, sixth-grade students act as 'student thermal scientists' to select the most efficient heating system for their school by understanding concepts such as heat, temperature, and molecular movement. Through activities like simulations and comparative analysis, students explore how energy transfer impacts heating system efficiency and the role of kinetic energy in temperature changes. This project includes creating models, conducting experiments, and developing reports to justify their recommendations using scientific principles, aligning with NGSS standards.

Entry Events

Events that will be used to introduce the project to students

Real-Life Heat Dilemmas

Students watch a video montage of various heating issues faced by people in different climates around the world, from dealing with chilly homes to energy-efficient solutions. This encourages a class discussion about the relevance of heating systems and energy transfer in everyday life and initiates their role as thermal scientists.

Build the Ideal School

Students participate in a digital simulation game where they must design their own school with a focus on optimal heating efficiency. This entry event challenges them to think creatively and apply scientific principles about energy transfer and molecule movement in a scenario directly related to their project goals.
