Core Skills Analysis
Science
- Will distinguished transverse from longitudinal waves, explaining how particles move perpendicular versus parallel to the direction of wave travel.
- He used the formula v = f × λ to calculate wave speed from measured frequency and wavelength during a ripple‑tank experiment.
- Will described how changes in frequency and amplitude influence the amount of energy a wave carries, citing examples such as sound volume and light brightness.
- He accurately employed scientific terminology—frequency, wavelength, amplitude, interference—in oral and written reflections.
Tips
To deepen Will’s grasp of wave theory, try a multi‑day investigation where he first builds a simple ripple tank, then varies the driving frequency to observe changes in wavelength and pattern. Follow with a classroom‑style debate on how different wave types (sound, light, water) transmit energy and information, encouraging him to draw analogies. Next, guide him to design a mini‑experiment measuring how two waves interfere, documenting constructive and destructive patterns with photos. Finally, have him write a short “scientist’s journal” entry connecting the observed phenomena to real‑world technologies like sonar or fiber‑optic communication.
