Mechanical WavesAP Physics 1, Big Idea 6, Investigation 13 In this advanced- inquiry lab, students use spring toys to explore waves and their properties. The lab begins with an introductory activity to visually represent the difference between longitudinal and trans-verse waves. Students generate waves in a Slinky® and make observations about the pulses that move along the spring. The procedure provides a model for guided-inquiry design of wave experiments to investigate the influence of frequency, ampli-tude and wavelength on the speed of the pulse.AP7734 I $68.55Speed of SoundAP Physics 1, Big Idea 6, Investigation 14 How fast does sound travel? This advanced-inquiry lab begins with an introductory cooperative class activity to determine the speed of sound in air using echoes as sound waves are generated and reflect off a flat surface. Students are then challenged to design a procedure to measure the speed of sound by employing the concepts of standing waves and resonance in a closed-end tube. The guided-inquiry activity includes a set of eight tuning forks so each group works with a different sound frequency. Students analyze and compare the two different methods of measuring the speed of sound.AP7735 I $194.30Electrical CircuitsAP Physics 1, Big Idea 5, Investigation 15 In this advanced- inquiry experiment, students use multimeters to determine the relationships between voltage, current and resistance for both series and parallel circuits. A teacher-led demon-stration begins the investigation by showing students the construction of simple, series and parallel circuits as well as how to measure voltage and current using a multimeter. The procedure provides a model for the guided-inquiry portion of the lab, which explores the additive nature of lightbulbs in series and in parallel circuits. A further opportunity for inquiry instructs students to construct circuits based on a prede-termined set of specifications, such as current, voltage and number of elements.AP7736 I $103.75Resistance and ResistivityAP Physics 1, Big Idea 1, Investigation 16 In this advanced-inquiry lab, students study how these three factors—resistivity, length and gauge—affect resistance. Students begin by investigating the resistance of nichrome wire using a multimeter and varying the sepa-ration of the measuring probes. This procedure provides a model for the guided-inquiry activity, during which students design an experiment to determine the effect the gauge of wire has on resistance. Error analysis of resistivity for each gauge of wire provides students with a method to assess their experimental design. Students may also investigate further by studying the effect temperature has on resistance.AP7737 I $103.65AP* PHYSICS 1 INQUIRY KITS, CONTINUED
