一.樂高能源組Renewable Energy Add-On Set-9688
The Renewable Energy Add-On Set is designed as an addition to the Simple and Motorized Mechanisms Set, the core set in our Machines & Mechanisms range. When the Renewable Energy Add-On Set is combined with the customized activity pack, students will explore renewable energy sources; investigate energy supply, transfer, accumulation, conversion, and consumption; and use measurements and data analysis to describe and explain outcomes through hands-on activities and exciting, real-life models.
Extend the use of the Add-On Set by combining it with the LEGO® MINDSTORMS® Education range. Students will experiment using energy from their own bodies and the three main energy sources – solar, wind, and water – to generate, store, and use power. When connected to the NXT Brick, the unique elements of the Renewable Energy Add-On Set (solar panel, generator, and LEGO Energy Meter) work as sensors.
