AP® PHYSICS 1
Speed of Sound—Inquiry Lab Kit
AP® Physics 1, Big Idea 6, Investigation 14
This advanced inquiry lab begins with a cooperative class activity to determine the speed of sound in air using echoes reflected off a flat surface. Students then design a procedure to measure the speed of sound by using the concepts of standing waves and resonance in a closed-end tube. Kit includes eight tuning forks so each group works with a different frequency. Students analyze the two methods of measuring the speed of sound.

FLINN SCIENTIFIC I AP® PHYSICS 1
Electrical Circuits—Inquiry Lab Kit
AP® 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 demonstration begins the investigation by showing students the construction of simple, series and parallel circuits as well as how to measure volt-
age and current using a multimeter. The procedure provides a model for the guid- ed-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 predetermined set of specifications, such as current, voltage and number of elements.

Resistance and Resistivity— Inquiry Lab Kit
AP® 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 separation of the measuring probes. This procedure provides a model for the guided-inquiry activity, during which students design an experiment to deter- mine 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.

Mechanical Waves—Inquiry Lab Kit
AP® 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 transverse waves. Students generate waves in a Slinky® and make obser- vations 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.
