Earth and Space

Misconception RESEARCH REVIEW

Thus explaining why the sky is blue. They may also think that we live inside the sphere. 

This misconception arises from seeing images of the Earth's shape. 

Diagnostic Resources

The following worksheets may help to identify whether students hold this particular misconception.

Resources to address this

  • The shape of the Earth (5-11)

    Ref - SPT HS02 TL02

    This activity includes common unhelpful ideas about the Earth. You'll need to explore the idea that the Earth is spherical explicitly, drawing on the children's ideas to challenge and develop their views.

  • Early ideas about the solar system  (11-14)

    Ref - SPT ES03 PN03

    The history of how our view of the heavens changed is fascinating. This is a reconstruction, identifying some salient points useful for science lessons.

  • Thales' model of the Universe  (11-16)

    Ref - Practical Physics / Astronomy /  Greek astronomy / Thales model of the Universe

    The early Greek philosopher Thales, in about 600 BC, proposed a model to explain the daily motion of the stars. You can demonstrate it using an umbrella.

    It will then be necessary to explore why this idea is not correct.
