About Dams

 Hydroelectricity is very much in the news and I have been developing some "hands on" projects to illustrate how dams create hydro power.  Hydro power was so important to economic development in Maine but also came at a price for waterways. This project engages students in the creation of a water wheel/water turbine toy that can also generate energy. They can learn the history of  these two forms of energy production --one that powered machinery and another that generated electricity. 

An additional function can illustrate optical science. The property of the "persistence of vision" was used in the 19th century Victorian Toy, the thaumatrope, an early form of animation. Students can create animations to appear when the side wheels spin.





URBAN HEAT ISLAND BOOK

 Another idea, still being tweaked!, is a simple book illustrated with stamps- or drawings by students-- to illustrate FAQ's about Heat Islands and ideas for mitigating the effects.




 How do you make a "hands on project" about Urban Heat Islands" ??   I scoured what is currently being offered and cobbled together two ideas into this Tin Can Green Roof project. Placed in the hot sun, students can measure the difference in temperature between the dark sides of the Tin Can with the coolness of the moss covered green roof.
