Wrong Things that we Learned in School

While schools may occasionally teach information that becomes outdated or erroneous over time, the overall goal is to impart accurate and dependable knowledge. However, due to the changing nature of information and the possibility of biases or limits in educational resources, facts taught in school may be proven to be wrong or inadequate. Here are a few examples of school-taught facts that have since been wrong.

Wrong Things Taught in School

Chameleons always adapt the colour to their surroundings

According to popular belief, these reptiles do not alter every time they come across a new colour. According to National Geographic, they can't even match every background they crawl up to. Yes, chameleons can alter their skin colour to match their surroundings, but their colour selections are restricted. Furthermore, when they aren't attempting to blend in, the colour of their skin changes to match their emotions.

Pluto's Planetary Position

Pluto was long thought to be the ninth planet in our solar system. However, the International Astronomical Union redefined what makes a planet in 2006, and Pluto no longer satisfied those criteria. It was downgraded to the status of "dwarf planet."

Christopher Columbus was the first to discover America

The popular assumption is that Christopher Columbus discovered America. In a 2005 survey conducted by the University of Michigan, 85% of Americans believed Columbus discovered the continent, while only 2% said Columbus couldn't have discovered America because Native Americans already lived there.

When your blood is deoxygenated, it turns blue

You were undoubtedly told that deoxygenated blood is blue when you were learning about your body. That, however, is not the case. Your blood is crimson regardless of whether or not it is in contact with oxygen. According to Live Science, the blue colour of your veins has something to do with how your eyes absorb and see colour.

Camels store water in their humps

According to common perception, parched camels in the desert do not store water in their humps. According to The Library of Congress, their mounds are loaded with fat, allowing them to travel for days in the desert without eating.

Taste Sections Make Up the Tongue

Remember those color-coded, simplified anatomical charts? Among them was probably this handy little diagram that showed how specific parts of your tongue were allocated to each taste. Unfortunately, the tongue map is complete rubbish. The hypothesis, which originated in a German article written by David P Hänig and published in 1901, was subsequently drastically oversimplified into the now-famous chart, which was first presented to the public by Edwin G. Boring in the 1940s. What is the truth? Thousands of taste receptors cover the tongue, allowing all five tastes - not just four - to register wherever on the tongue.

The sky is a brilliant blue as a result of the Ocean (or vice versa)

The age-old inquiry, "Why is the sky blue?" It's because of the ocean and how it reflects in the sky, according to outmoded pop science, your often inaccurate know-it-all uncle, and a very elementary scientific course you took in school. That may be a beautiful straightforward answer, but it's inaccurate. Neither is the inverse true. Both derive their gorgeous blue hues through a phenomenon known as the "Raleigh Scattering Effect." Essentially, the molecular constitution of both causes short wavelengths of blue light to scatter better than long wavelengths of red, yellow, and orange light. As a result, the sky and water appear blue!
