AP* PHYSICS 1 INQUIRY KITSMeasuring g: Exploring Free-Fall AP Physics 1, Big Idea 3, Investigation 1 The lab begins with an introductory activity in which students solve for the acceler-ation due to gravity, g, by dropping small steel balls a known distance and measuring their free-fall times. The guided-in-quiry and design activity encourages students to use their experimental-design skills to refine the procedure presented in the introductory activity to minimize experimental error. Increase the wow factor of this lab by dropping items from bleachers or other very high places. Additional opportunities for inquiry are possible as students may attach hand-made parachutes or drop coffee filters to assess how wind resis-tance, or drag, affects free-fall speed.AP7722 I $45.75Graphing MotionAP Physics 1, Big Idea 3, Investigation 2 In this lab, students gain an understanding of the laws of kinematics as they compete with classmates to match given motion graphs. The lab’s introductory activity familiarizes students with the laws of kinematics and the use of motion detectors by asking them to draw simple position vs. time and velocity vs. time graphs. The guided-inquiry and design activity challenges students to monitor their walking speeds using motion detectors to replicate position vs. time and velocity vs. time graphs of increasing complexity. Additional opportunities for inquiry include tests to determine a motion detector’s range and its reliability at long distances.AP7723 I $16.85Newton’s Second LawAP Physics 1, Big Ideas 2 & 3, Investigation 3 The investiga-tion begins with an introductory activity in which students are presented with a modified Atwood’s machine consisting of a Hall’s carriage connected to a hanging mass. As students make observations, ask questions, explain and predict, they iden-tify variables that affect the acceleration of the system. Then students design and carry out experiments to determine the acceleration of the system by first manipulating the net force on the system and then by manipulating the total mass of the system. An analysis of the results leads to a deeper understand-ing of the relationships among the net force exerted on an object, its inertial mass and its acceleration. AP7724 I $196.95Coefficient of FrictionAP Physics 1, Big Idea 3, Investigation 4 The purpose of this advanced-inquiry lab is to design a procedure to identify the physical variables that affect the force of friction between two objects. The lab begins with an introductory activity to determine the coefficient of static and kinetic friction between a wood block and a tabletop. Students create and use free-body diagrams to analyze each situation. The procedure provides a model for the guided-inquiry activity, during which students design and carry out experiments to determine variables that influence fric-tional forces between surfaces.AP7725 I $104.55
