Science Kit<br />
Practice and Demonstration Set for Solar Hydrogen Technology<br />
The Science Kit is an extensive experiment set for the<br />
subject of renewable energies. 20 pre-configured<br />
experiments and accompanying materials make it a<br />
complete solution for physics and chemistry lessons.<br />
Includes<br />
Instructional<br />
Materials<br />
School Level<br />
The components form a complete solar-hydrogen energy conversion<br />
chain and can be flexibly combined with one another. The topic of<br />
renewable energies can be approached in consideration of the entire<br />
conversion chain or on the level of the individual technologies, such<br />
as photovoltaics or fuel cells. All components can be used and investigated<br />
separately.<br />
