NGSS Connections

1-PS4 – Waves and their applications in technologies for information transfer

  • make observations to construct an evidence based account that objects can be seen in darkness only when illuminated
  • plan and conduct investigations to determine the effect of placing objects made with various materials in the path of a beam of light.

4-PS4 – Waves and their applications in technologies for information transfer

  • develop a model to describe that light reflecting from objects and entering the eyes allows objects to be seen
