- Sun Spot Analysis Introductory students use Excel to graph monthly mean Greenwich sunspot numbers from 1749 to 2004 and perform a spectral analysis of the data using the free software program "Spectra."
- Discovering Velocity Outside of the Classroom This activity is an outside the classroom teaching with data experiment. It allows students to collect and analyze data in ordet to create a distance versus time graph and calculate average velocity from the graph.
- Measuring the Coefficient of Friction of a Skater On Ice Students use video analysis of ice skaters gliding across the ice to determine the coefficient of friction between the skates and the ice. Materials include instructions and six videos that can be used for analysis.
- Reflection and Absorption of Light Students use a microcomputer connected to a light sensor and temperature probe to explore the reflection and absorption of light.
- Measuring Velocity of Objects Using Video Clips Students learn to determine the velocity of moving objects by doing simple analysis of video clips.
- Conservation of Energy of an Object while Rolling Down a Hill Students analyze video clips of kids rolling down a hill on skates, scooters, and bikes to determine whether mechanical energy is conserved.
- Conservation of Energy of a Rollercoaster Using High Speed Video A high speed video clip of a roller coaster is used as an example of conservation of mechanical energy. Student use the video to determine whether mechanical energy is conserved while the roller coaster rolls up, and then back down a hil.
- Analysis of Simple Harmonic Oscillator in a Single Video Clip One video clip, with embedded graphs, can be used to help students understand the mathematical relationships that describe simple harmonic motion.
- Virtual Photoelectric Lab This is a virtual lab activity on the photoelectric effect based on a Java applet simulation of the experiment.
