What do you think about these sentences?

Giraffes are short.

The sky is purple.

Bears have stripes.

Stars are in the ocean.

Fish are in the desert.

Did these sentences make much sense? I bet most of you are thinking, "What? That isn't right!" Maybe you have been to a zoo and seen that giraffes are tall and bears are usually brown, back, or white. You have seen the sky and know that it is usually blue. You have seen stars in the sky, and fish in the ocean!

There seems to be some difference in what your prior knowledge (what you knew before reading this) and this experience is making you think! This difference is called disequilibrium. Now you probably want to find out which is true! You were right. All of your prior knowledge was correct!
