Top 10 Lies Of Science Your Teachers Told You In School

Myths and tales are found in every culture but the common thing all these cultures have is the scientific lies taught to their children at early ages. Whether it was the ignorance of primary school teachers or it was done to prompt us to question and not to accept easily whatever is taught, they all seem funny now. Some of the lies we all have grown up with are listed as follows.

10. Duck’s Quake does not Echo
When inquired about the inaudibility of ducks’ quack, I was told that unlike other sounds it does not echo and thus does not reach our ear drum for us to sense that. But science has now proven it otherwise. It’s not about the quake being special not to echo but our ears who cannot respond to the particular frequencies the sound has due to some external conditions. This fact was proved after performing series of experiments in which the duck was allowed to quack in a room specially designed to reflect sound waves. The echo was then heard which put to rest the myth about its uniqueness
