Students use the CBL to collect data on the brightness of different light bulbs and associate these values with the watt ratings for each bulb. Then they will graph the data and compute the rate of change.

Egg drop competition is a popular activity to reinforce the lessons in force and motion. In the activity, the students are asked to design a vehicle to carry the egg safely when dropped from a height of 10 feet (about 3 m) or more.
Realtime and concrete data collected and analyzed during the design process of the vehicle can help the students think critically. The activity is both fun and selfmotivating for the students.

Students explore the relationship between power, work, and time. They also explore the relationship between power, force, and speed. Based on these explorations, students derive the equation P = Fv and solve problems dealing with power in various mechanical problems.

Students collect data on the motion of a simple pendulum. They then graph the acceleration of the pendulum vs. its displacement to show that the displacement of the pendulum is directly proportional to the force acting on it. They use this information to confirm that the motion of the pendulum fulfills the requirements of simple harmonic motion.

Students will use a simulated pendulum to collect data on length and period. Then, they will develop mathematical models of the relationship between the length of a pendulum and its period. They will confirm that the relationship is nonlinear and that period is directly proportional to the square root of length.

Students investigate the acceleration data for a taxiing Boeing 737 to calculate the velocity of the plane as it taxies down the runway.

Students investigate the relationship between sound intensity and distance for a commercial loudspeaker. They use collected data to identify a mathematical model for the relationship. They then compare this model with the inverse square law for an ideal point source.

This is a program allowing teacher/student to interactively and graphically investigate a variety of wave concepts commonly studied in physics: traveling waves, standing waves, beats, Doppler effect, twopoint source interference, Fourier wave forms, reflection and refraction, amplitude modulation, and attenuation.

In this activity, students explore the refraction of a single light ray. They begin by exploring light traveling from a less dense medium into a denser medium. They use a numerical approach to establish a relationship between the angle of incidence and the angle of refraction. Then, students explore refraction when the light ray travels from the denser medium to the less dense medium. Students check to see if their relationship still holds and determine the critical angle.

Students explore the characteristics of capacitors. The activity begins with a look at the movement of charge in a parallelplate capacitor and the effect of voltage on charge. Following the definition of capacitance, students explore how plate area, plate separation, and dielectrics affect capacitance. The activity ends with an investigation of the rate of discharge of a capacitor in an RC circuit.
