Pick a week to start (or pick up where you left off). Each week has Mon-Fri lessons and a celebration recap.
// Speed is distance divided by time
// What changes a motion, and what leaves it alone
// The same push, a different result
// The force that brings every ball back down
// The forces that slow things down
// The energy of motion
// Energy that waits
// Where the energy goes
// Every push has a push back
// Magnets, charges and fields
// Forward motion meets gravity
// Criteria, constraints, build, test, improve
