In this activity, students observe fruit through colored lenses or cellophane and attempt to explain why fruit looks different through different lenses.
In this activity, students observe the oscillations of a mass on a ...
In this activity, students observe the oscillations of a mass on a spring in air and water. They will use a stop watch to time several periods and estimate periodicity from this.
In this activity, students send a longitudinal wave along a large slinky ...
In this activity, students send a longitudinal wave along a large slinky and experiment with changing the amplitude of the waves and wave speed by changing the tension of the slinky.
In this activity, students place glass marbles into a clear liquid with ...
In this activity, students place glass marbles into a clear liquid with the same refractive index as the marbles and observe as the marbles seem to disappear.
In this activity, students hang masses on springs and use a stop ...
In this activity, students hang masses on springs and use a stop watch to investigate the effects of mass on period of oscillation. They will also investigate the effect of spring constant and amplitude of oscillations.
In this activity, students strike a tuning fork at the top of ...
In this activity, students strike a tuning fork at the top of a tube. They then raise and lower the tube and lsten to the sound get louder and quieter. They should try to find the resonance length and from this they can find the frequency which the tuning fork produces.
In this activity, students use a ripple tank to produce parallel plane ...
In this activity, students use a ripple tank to produce parallel plane waves and investigate the effects when small and large objects are placed in front of the wave or when waves must pass through slits.
In this activity, students use a ripple tank to experiment with making ...
In this activity, students use a ripple tank to experiment with making waves of different shape and frequency. They will use a stroboscope to "freeze" the waves and measure the wavelength of the waves. They will also observe the effect of varying the frequency on wave speed and wavelength.
In this activity, students produce standing waves on a taut cord or ...
In this activity, students produce standing waves on a taut cord or wire. They will vary the tension in the string to see the effect this has on the frequency.
In this activity, students observe the color of scattered light coming out ...
In this activity, students observe the color of scattered light coming out of the sides of a beaker filled with water and a few drops of milk. The light should be projected onto a white wall or screen for easy observation.
