The writer, John Malam, initiates this topic with the word waterfall. This topic about Angel Falls, which is known as the highest waterfall in the world. Other important waterfalls are Khone and Niagara Falls. The physical features of the waterfalls- cliffs, plunges, gorges, and water erosion are really significant for the middle school earth and environmental science. The students will inquire about how Niagara falls moved backward 1000 feet within 300 years after seeing the individual parts of the waterfall. The portion on waterfall daredevils is really significant for further research on Niagara falls, the law on fiction, mass and etc. The most interesting part is how the Torrent ducks and the dipper live and eat near waterfalls and how salmon can swim against the current of waterfalls. Another important part is the hydroelectric power which can be created through the dam by using a turbine machine and electrical power. This chapter highlights many scientific terms like plunges, cliffs, shale, etc. ( )
