  • What's the Big Idea? Understanding the Laboratory Experience in the AP* Chemistry Curriculum If you teach AP* Chemistry, you’re already aware, or need to be, that changes to the course curriculum are here, which means you’ll probably have to change your classroom instruction. To help relieve your anxiety, here’s an overview of the course revisions, some important dates to remember, and 2 ways Carolina can help to ensure your success during this transition. View »
  • Minimizing Forces During a Collision Students utilize and apply concepts including force, energy transformation, conservation of energy, momentum, conservation of momentum, and Newton's laws of motion. View »
  • Ideal Atwood Machine Use this classic physics problem to analyze the forces acting on a set of weights suspended over a pulley. Calculate the acceleration of the system by applying knowledge of Newton's second law of motion, free-body diagrams, and kinematics. View »
  • Electrify Your Classroom with a Discussion on the War of the Currents, Past and Present When great scientists of the 19th century squabbled before the public, both types of electric current flowed. George Westinghouse and Nikola Tesla battled Thomas Edison over whether AC or DC would carry power across the grid in the US. View »
  • Newton's Law of Cooling Confirm Newton's law of cooling by collecting and analyzing data on samples of water undergoing a temperature change. View »
  • Derivation of the Kinematics Equation A solid understanding of kinematics equations and how to employ them to solve problems is essential for success in physics. Take a quick look the algebraic derivations behind these equations. View »
  • Ring and Disc Demonstration Gain a deeper understanding of the classic ring and disc physics demonstration designed to introduce the concepts of rotational inertia, rotational motion, and rolling motion. View »
  • Energy Transformations in a Dark Detector This activity is designed to give students the opportunity to design, build, and test a dark detector circuit. A dark detector is a simple circuit that can be used to explain the function of a light-dependent resistor and a transistor, two common electrical components. View »
  • Energy Is Energy Energy that we use has to come from somewhere. Even though one form of energy may seem different from another form, it really is all the same. Energy is energy. View »
  • Build the Fastest Car in the World...that Goes Roughly 0.1 m/s The inclined plane can be used to explore a variety of fundamental concepts, including static and kinetic friction, dynamic equilibrium, unbalanced forces, and the work-energy theorem. In this experiment, your students design a car using the Visual Scientifics system and a smartphone. View »
  • Single Function Signal Generator Want to avoid using expensive equipment to generate a variety of electrical waveforms for your students to analyze? Think flowers! But not just any flowers—think plastic, solar-powered, dancing flowers. View »
  • The Problem with Pulleys Build and test working models of pulley systems commonly used in problems in physics texts and tests. View »
