Mountain to Climb:

Lake Champlain is under attack from algae blooms! Navigators, your Mountain to Climb this week is to demonstrate how big of a problem algae blooms are. If you start out with a 3 foot-by-3 foot square of algae on the lake, calculate how large it will get in one day. How about in one week? Then, compare the size of the algae bloom to football fields or swimming pools.

But his bold protest fizzles: within days the casino is back in business, and Noah’s dad is behind bars and out of action. Now Noah is determined to succeed where his father failed. But even though pumping raw sewage into the waters of the Florida Keys is both gross and against the law, turns out it’s near impossible to catch the flusher especially when he’s already bamboozled the prosecutors, the local press, and even the Coast Guard.
