AP* PHYSICS 2DiffractionAP Physics 2, Big Idea 6, Investigation 14 In this advanced-inquiry investigation, students devise a method for measuring the width of very thin materials by taking advantage of the principles of diffraction. The introductory activity provides instructions for setting up an apparatus to create diffraction patterns by shining monochromatic red laser light at the edges of various materials. The guided-inquiry activity challenges students to devise a means for calculating the widths of the various materials and assessing experimental error. AP8008 I $45.85The Photoelectric Effect AP Physics 2, Big Ideas 5 & 6, Investigation 15 This advanced-inquiry investigation explores the photoelectric effect. In the introductory portion of the experiment, an electroscope is used to demonstrate the idea that different materials have different work functions or minimum energy thresholds that must be overcome to emit electrons. This first part also serves as an introduction to the concept that light energy can be used to move electrons. The guided-inquiry portion of the experiment demonstrates that light’s intensity is not the determining factor in electron emission from a material; rather it is the frequency or energy of the incoming light. Students must confirm this idea by using lightbulbs of different intensities along with a phosphorescent strip and set of filters that transmit light of only one wavelength. AP8010 I $89.75Modern TopicsAP Physics 2, Big Ideas 5 & 7, Investigation 15 This advanced-inquiry lab uses a guided-in-quiry activity-station approach with four self-contained labs that can be completed in any order:• Half-Life—Understand the concepts of half-life and the probabilistic nature of radioactivity through the use of multifaceted dice simulations. • Hydrogen Spectrum—Learn how absorption and emission spectra can be extrapolated to understand the composition of distant celestial bodies.• Radioactive Decay Cards—Arrange element cards and beta and alpha particle cards to investigate the natural decay of uranium-238.• Quantum Leap—Discover how electron location in orbitals corresponds to probability.AP8009 I $147.35Refraction and LensesAP Physics 2, Big Idea 6, Investigation 12 The lab begins with introductory activity to investigate Snell’s law using a gelatin-filled dish and laser pointer. Students draw the rays of incidence and refraction and compare the angles. A series of guided-inquiry questions lead students to predict focal lengths of concave and convex lenses and the location and type of images formed. Students then perform experiments to confirm their predictions. Enough materials are provided for six student groups to perform the introductory activity and for a single demonstration setup of the guided-inquiry equipment. Additional lenses, meter stick optics equipment and lasers are available separately.AP8007 I $65.95AP* PHYSICS 2 INQUIRY KITS, CONTINUED
