AP* PHYSICS 2Electric Field Mapping AP Physics 2, Big Idea 2, Investigation 6 This advanced-inquiry lab begins with an introductory activity that familiarizes students with mapping equipotential lines of a dipole charge setup. Next, guiding questions lead students to map out the field lines themselves and to consider various potential setups that would produce differ-ent electric field configurations. This lab uses high-quality conducting ink pens and greatly enhances students’ understanding of an abstract and difficult concept. AP8001 I $133.00Capacitance and RC CircuitsAP Physics 2, Big Idea 4, Investigation 7 This advanced-inquiry lab first guides students through an introductory activity in which they build their own capacitors and study the variables that affect how much charge can be stored. This introduces students to how a potential difference is created across parallel conducting plates and gives them insight into the charging period of a capacitor. With the help of a capacitance meter, students evaluate the important parameters. In the guided-inquiry activity, students use their capacitor along with known capacitors in a circuit containing an LED, which allows for a semi-quantitative measurement of the time constant of an RC circuit. This introduc-tion to capacitance and the visual representation of the time constant gives students the know-how to further develop their understanding of conservation of electric charge in complex circuits. AP8002 I $128.05Thermal ConductivityAP Physics 2, Big Idea 5, Investigation 4 In this advanced-inquiry investigation, students use two methods to explore quantitatively the abilities of various materials to conduct thermal energy. In the introductory activity, students press their wrists against plastic and metal spoons to come up with a qualitative description of the heat transfer inherent in such contact. In the guided-inquiry portion of the investigation, students explore two slightly more quantitative methods for determining thermal conductivities and then make informed comparisons between the two methods. The guided-inquiry activity promotes deep thinking as students must question the limits of their various experimental designs. AP7999 I $107.70Investigating Electric ChargeAP Physics 2, Big Ideas 1, 3 & 5, Investigation 5 The purpose of this advanced-inquiry lab is to obtain an understanding of the fundamental property known as electric charge. Students begin with an introductory activity in which they investigate electrostatic interac-tions between pieces of tape. Students develop an understanding of opposite charges and how charges are transferred. This initial experiment sets the stage for the guided-inquiry design of a procedure to determine the magnitude of electrostatic charge on a hanging pith ball. The results give students applicable experience with Coulomb’s law and help them understand a challenging concept.AP8000 I $54.90AP* PHYSICS 2 INQUIRY KITS, CONTINUED
