30 Common School Facts That Are No Longer True

Educational curriculums often include a variety of foundational subjects, such as chemistry, algebra, and grammar. However, many of the facts taught in these classrooms have since been debunked or updated as scientific and historical understanding evolves.
From health myths to scientific misconceptions, many students have encountered inaccuracies in their education. These errors often stem from historical oversights, the proliferation of urban legends, or the oversimplification of complex events to the point of falsehood.
Scientific and Medical Misconceptions
Science is a process of constant evolution, meaning that textbooks can quickly become outdated. Some of the most common inaccuracies found in school lessons involve biology, astronomy, and basic physics.

One widely taught scientific fact that was proven incorrect for many students before 2006 concerned the status of Pluto. For a long period, Pluto was categorized as the smallest and ninth planet in the solar system.
In 2006, Pluto was reclassified as a dwarf planet. This change occurred following the discovery of other objects in the Kuiper Belt that were comparable in size to Pluto.
Other scientific myths frequently addressed in educational settings include the shape of raindrops. While often depicted as being shaped like teardrops, this is not accurate.
Similarly, the popular story of Isaac Newton discovering gravity because an apple hit him on the head is listed as a misconception that has been debunked.
Health and Anatomy Myths
Health classes have historically been prone to inaccuracies, sometimes utilizing scare tactics rather than established facts to convey information to students.
A notable example of a medical misconception involves the dental history of George Washington. It has been commonly taught that Washington had wooden teeth.
In reality, Washington’s dentures were constructed from a variety of materials. These included ivory, cow teeth, and human teeth, rather than wood.
Historical Inaccuracies
History lessons often gloss over crucial details or rely on narratives that do not align with historical evidence. These inaccuracies can range from the lives of famous artists to the origins of national holidays.
The narrative of Vincent van Gogh as a tortured artist often includes the claim that he cut off his own ear. However, recent historical claims suggest that he actually lost his ear during a fight with another artist, Paul Gauguin.
Similarly, the story of Christopher Columbus discovering America is considered inaccurate. While Columbus landed on islands in the Bahamas, he never stepped foot on the North American continent.
Other historical myths taught in schools include:
- The belief that Pilgrims and Native Americans sat together at the first Thanksgiving.
- The claim that the Great Wall of China is the only man-made structure visible from space.
- The misconception that Albert Einstein was a bad student.
Whether students attended private academies or public schools, these examples highlight the importance of reevaluating learned information against expert sources and updated research.
