Seeing the Light

In Science last week Mrs Hepworth’s and Mrs Bellette’s Year 5 classes investigated the properties and nature of light.  This included light travelling in straight lines from a source and how it interacts with different materials, how light can form shadows and be refracted or absorbed and how light can manipulate what we see.

The students worked their way around 8 stations and tried different experiments to see how light can reflect, refract and absorb.  There were lots of ‘lightbulb’ moments (pun intended) as the groups read about and discovered the scientific reasons this happens.

Students were asked to investigate how light travels in a straight line by recreating a digital experiment

      

Use mirrors to manipulate light to appear in a different position than the line from the torch (reflection)

Make the tallest and shortest shadow  and record where the source of light is in relation to the popstick.

Use a glass of water to change the direction the arrow is facing (refraction)

Investigate how our brain can mix the signals when looking at reflections (optical illusions)

Use light to manipulate colour

Use a prism to create a rainbow

 

 

and investigate how light travelling through different translucent substances can change the way we view the object

   

These experiments were also a great opportunity for the students to use scientific skills in investigation, note taking, prediction and questioning, team work, clarifying ideas using experiments and use scientific vocabulary to discuss and explain phenomenon .
