Light Energy

This year, we have centered our focus to the study of physical sciences.  So far, we have studies electricity, magnetism, and simple machines. Next, we will be studying the different types of energy, beginning with light energy. Here are a few learning objectives, vocabulary terms, notebooking activities, and resources that can be use with the study of light energy:

  •  Understand that light is energy.
  •   Explain the characteristics of light.
  •  Identify sources of light.
  •  Classify light sources as artificial or natural.
  •  Be able to explain how people see.
  •  Explain the speed of light and its formula.
  •  Understand the difference between reflection and refraction.
  •  Be able to explain how shadows are formed.
  •  Identify the types of tools needed to view objects better.
  •  Learn about famous scientists and their contributions to the study of light.
  •  Learn about careers in light and optics.
  •  Be able to explain how lasers work.





Vocabulary:

Notebooking Activities:
  • Draw and label a diagram of the color spectrum.
  • Draw and label a diagram of Electromagnetic waves spectrum.
  • Classify types of artificial light and natural light in a chart.
  • Create vocabulary flapbooks.
  • Research careers dealing with light and optics:
    • Optician
    •  Audio and video recording technician
    •  Photographer
    • Ophthalmologist
  • Research  famous scientists and tell their contribution to the science of light energy and its uses: 
    •   Albert Einstein
    •  Heinrich Hertz
    •  Christian Huggens
    • Sir Isaac Newton
    • Galileo
    • Wilhelm Conrad Roentgen
    • Anton Van Leeuwenhoek
Below, you will find a list of resources that can be used.  Because of the various ages of my children, you will find a wide range of grade levels.  Simply utilize the resources that are suitable for your child's grade level.  Although most of the resources are free, some are available for a fee or require a membership.  

Resources:
  • Elementary Advantage 2009 or 2010 (The 2011 version does not contain the science modules!)
  • Engineering Interact ( Contains modules, module questions, and applications.)
    • Light sources and light rays
    • Reflection: seeing objects
    • Shadows
    • Reflection: mirrors
