The 6th grade science curriculum here focuses on earth science, followed by life and physical science in the next two years.

There is no better spot in the county to observe and explore geology and natural history than right here, on the Cap Vert Peninsula. The geological story includes the opening of the Atlantic following the break-up of Pangea, and two relatively recent but distinct volcanic events: the earlier during the Tertiary Period, about 8 mya, when the area around downtown Dakar was formed, along with Ile de Madeleine and Ile de Goree; and the more recent, about 1 mya, with the explosive eruption of the now extinct Mamelles volcanoes.

Cool, eh?!

Note to self: Produce a Bill Nye-esque video program with the kids featuring the natural history of the peninsula, filmed on location.

The field trip to Cap Manuel is extraordinary, with basalt columns (we found an area where we could walk across the upper surface of the columns), and access to the basement limestone. It is also the site of very interesting and overlapping histories: a large assemblage of stone tools were excavated here (now housed at the University of Dakar); and the remnants of WWII era French gun emplacements are numerous, the specific history of which I've begun exploring. Squatters now reside in the gun emplacements. What a view!
