Life is like trying to juggle three tennis balls! That's the big idea in a lesson that asks freshmen to consider that sometimes juggling the areas of their lives (social/emotion, academic, and career) runs smoothly and sometimes not so...

Students hypothesize about the nature of falling objects, design an experimental test to answer the question using everyday objects, analyze data to form conclusions, and infer that mass does not affect the speed of falling objects. This...

Middle schoolers examine the law of conservation of momentum. In this physics lesson, students play marbles in order to compare the mass of the marble and velocities effects. Middle schoolers receive directions of the marbles game and...
