Science week fun in Team CB

​During this session, the class discussed how sometimes our growing bodies use rules and guesses when they look at or experience something. To test this, the children were shown the Jastrow illusion and asked which arch was bigger. Unanimously, the children all believed that B was bigger. To test this children cut out each arch, swapped their position and laid them on top of each other, eventually concluding that they were both the same size after measuring with a ruler. We then investigated the Ebbinghaus illusion. Again, children all thought that the largest orange circle was in the smaller flower. To prove that they were in fact both the same, we cut them out. Extending from this activity, children created their own illusion using two 10cm lines. We discussed why one line appeared longer than the other despite knowing that they were the same length. As a class we explored how our brain can sometimes work so quickly that it seeks to make links that are not actually a true reflection of the experience at hand.
