Hooke’s Law and Simple Harmonic Motion for Elastic Materials AP Physics 1, Big Idea 3, Investigation 9 In this lab, students determine the stretchiness, or spring constants, for a rubber band and spring. The lab begins with an introductory activity in which students cause elastic materials to exhibit simple harmonic motion so they can measure spring constants by monitoring oscillating frequencies. Students use these results in the guided-inquiry activity to design a procedure to evaluate whether the mate-rials obey Hooke’s Law. As an additional activity, students may attempt to replicate a safe, yet thrilling bungee jumps by constructing a bungee cord of materials with appropriate spring constants to prevent an egg from crashing into the ground.AP7730 I $50.05Simple PendulumsAP Physics 1, Big Idea 3, Investigation 10 In this advanced-inquiry activity, students inves-tigate the properties of swinging pendulums and design an experiment to test and identify multiple variables to determine what affects the period of a pendulum’s swing. Students begin with an introductory activity to learn the proper experimental technique. Then the guided-inquiry activity leads students to deter-mine variables that may affect the period of a pendulum’s swing. Interpreting the data and incorporating graphical analysis confirms rela-tionships between the tested variables.AP7731 I $38.70Rotational Motion and Angular MomentumAP Physics 1, Big Ideas 3 & 4, Investigation 11 In this advanced-inquiry lab, students first conduct a series of experiments designed to investigate the connections between rotational motion and angular momentum. By studying the rates of falling masses connected to a multi-pulley coaxial wheel and axle, these relationships are revealed. In a guided-inquiry challenge lab, students use this knowledge to select the proper pulley and hanging mass combination that results in the hanging mass taking exactly 4.00 seconds to strike the ground!AP7732 I $199.10TorqueAP Physics 1, Big Idea 3, Investigation 12 In this advanced-inquiry activity, students are challenged to hang a “sign” over a sidewalk for the lowest material cost. The investiga-tion begins with an introductory demonstration of first-, second- and third-class levers and torque. Students then investigate the forces required to achieve static equilibrium for various combinations of levers and forces. These results provide a model for the guid-ed-inquiry design of the most structurally safe and efficient way to hang a sign. Students experiment with various combinations of cable lengths and sign positions as they collect data on the forces of torque acting on the overall structure. Analysis of the data leads to actual construction the chosen design.AP7733 I $139.35AP* PHYSICS 1 INQUIRY KITS, CONTINUED
