Kids perceptions on how the world works... you'd be amazed how they think!

Kids perceptions of how things work
Knowing how kids think matters.

Ever wondered what kids are thinking?
Just how do students perceive their world when their background to measure their experiences is limited?


As many teachers and psychologists know, it's the lens of your past experiences through which you understand the world. There is a whole bunch of literature around 'children's science', whereby in the absence of scientific guidance from adults, kids will formulate their own interpretations of how the world works. To be honest who could blame them? If no-one is there to guide them, kids are forced to create reasons for how things work themselves. 
In many cases, even what adults might see as basic concepts can be completely missed by kids and often produces some amusing results. Of course whilst adults can get a smile from an innocent explanation that's off the mark, it does highlight the point that students will naturally formulate their own conclusions from any science lesson... this means that even pointing 'the obvious' is still a critical process. Why? Well, here's a few examples:

  • You can't assume that the children in the room actually know what you're talking about.
  • Kids might have a completely different idea of a scientific process before the lesson. Remember, it's not that long ago that people thought the world was flat, that atoms didn't exist and that the Universe revolved around the Earth. There are still parts of the world that still cling to these notions...
  • Any prior learning could have produced a series of 'half-truths', in that the kids get only part of the previous lesson and bring this into the next. This might mean that critical information from your previous science lesson is missing and this brings in the potential for the student's to get lost very quickly with the new content.
The best way to pick up on these issues is to simply keep questioning kids understanding of a concept. Ask 'why?' as many times as possible so that students can tell you what they know. It may be worth going over old content before explaining new ideas to students, a practice tried and tested in many a classroom across the world.

Anyway, with all this in mind it might be interesting to outline some of the student misconceptions that we've heard whilst running touring school science shows & workshops. Some of these misconceptions are well known, others very much came from left field... but all showed both the attending teachers and ourselves that you can never assume that the students in front of you are formulating their ideas in exactly the way you expect! In no ways is this a definitive list, some of this is directly from our science shows and some of this has been adapted from the references at the bottom of this post. If you want to add some more place them into the comments section :)
Atmosphere misconceptions

  7. Humans are the end point and pinnacle of evolution

Astronomy misconceptions
  1. Stars and constellations appear in the same place in the sky every night.

  2. We experience seasons because of the earth's changing distance from the sun (closer in the summer, farther in the winter).

  3. The Moon can only be seen during the night.

  4. The Moon does not rotate on its axis as it revolves around the earth.

  5. The solar system contains only the sun, planets and the moon. This might be due to the classic solar system models that are shown in class.

Colour and Vision misconceptions
  1. The pupil of the eye is a black object or spot on the surface of the eye.

  2. The lens is the only part of the eye responsible for focusing light.

  3. The lens forms and image (picture) on the retina. The brain then "looks" at this image and that is how we see.

  4. A white light source, such as an incandescent or fluorescent bulb, produces light made up of only one colour.

  5. Sunlight is different from other sources of light because it contains no colour.

  6. The rules for mixing color paints and crayons are the same as the rules for mixing coloured lights.

  7. The primary colors for mixing coloured lights are red, blue and yellow.

  8. A coloured light striking an object produces a shadow behind it that is the same colour as the light. For example, when red light strikes an object, a red shadow is formed.

  9. When white light passes through a coloured filter, the filter adds color to the light.

  10. Colour is a property of an object, and is independent of both the illuminating light and the receiver (eye).

Electricity misconceptions
  1. Positively charged objects have gained protons, rather than being deficient in electrons.

  2. Electrons which are lost by an object are really lost (no conservation of charge).

  3. A circuit 'uses up' electricity.

  4. The electrostatic force between two charged objects is independent of the distance between them.

  5. Gravitational forces are stronger than electrostatic forces.

  6. Batteries have electricity inside them.

Forces and Motion misconceptions
  1. If an object is at rest, no forces are acting on the object.

  2. A rigid solid cannot be compressed or stretched.

  3. Force is a property of an object. An object has force and when it runs out of force it stops moving.

  4. A force is needed to keep an object moving with a constant speed.

  5. Friction always hinders motion. Thus, you always want to eliminate friction.

  6. Acceleration is confused with speed.

  7. Acceleration always means that an object is speeding up.

  8. Acceleration is always in a straight line.

As you can see there are a large number of student misconceptions that can be behind students eyes when they're in your science lesson. You'd be surprised just how many of these misconceptions are carried on to adulthood too! What have you experienced? I'd love to hear your thoughts! 

All the best,
