Physics stars design mobiles that demonstrate rotational equilibrium. They take measurements and solve related equations for force by graphing, substitution, or determinants. This is a well-developed lesson plan, complete with student...

Scholars learn how to crack secret codes as they continue reading from the Blown to Bits and try to crack the random substitution cipher. They also begin learning about the Vigenere cipher. 

Many things in life take the shape of a polynomial curve. Learners design a polynomial function to model a riverbed. Using different strategies, they find the flow rate through the river.
