Which of the following statements is a myth?
Humans use only 10% of their brain
Water boils at 100°C at sea level
Light travels faster than sound
The Earth orbits the Sun
The idea that humans use only 10% of their brain is a popular misconception with no scientific basis. Brain imaging shows activity throughout the entire brain even during simple tasks.
Which of the following statements is true?
Water boils at 100°C at sea level
Ice is heavier than liquid water
All metals are magnetic
Sound travels faster than light
At standard atmospheric pressure at sea level, pure water boils at 100°C. The other statements are false because ice is less dense than liquid water, not all metals are magnetic, and light travels much faster than sound.
Which of the following statements is true?
Tomatoes are fruits
Goldfish have a three-second memory
Bats are blind
Sugar causes hyperactivity in children
Botanically, tomatoes develop from the ovary of a flower and contain seeds, making them fruits. The other statements are common myths without scientific support.
Which of the following is a misconception about seasons?
Seasons occur because the Earth is closer to the Sun in summer
Seasons occur due to the tilt of Earth's axis
Equinoxes mark equal day and night lengths worldwide
Seasons last exactly three months each
Seasons are driven by the tilt of Earth's axis, not its distance from the Sun. While distances vary slightly, they do not cause seasonal temperature changes.
Which of the following statements about lightning is true?
Lightning is hotter than the surface of the Sun
Lightning never strikes the same place twice
Lightning only occurs during thunderstorms
Lightning travels from ground to cloud only
A lightning bolt can reach temperatures around 30,000°C, far hotter than the Sun's surface at about 5,500°C. The other statements are misconceptions about how lightning behaves.
Which of the following statements is a myth?
People swallow eight spiders a year in their sleep
The Earth orbits the Sun
Water boils at 100°C at sea level
Humans have 206 bones
The notion that people swallow eight spiders a year during sleep is an urban legend with no evidence. The other statements are scientifically verified facts.
Which of the following claims about the Great Wall of China is false?
It is visible from low Earth orbit with the naked eye
It was built over various dynasties
It stretches over 13,000 miles
It was primarily constructed as a defense barrier
Although impressive in length, the Great Wall is not visible to the naked eye from low Earth orbit. Astronauts report it blends into the surrounding terrain.
What is the Mpemba effect?
Hot water can freeze faster than cold water under certain conditions
Cold water boils faster than hot water
Heat always transfers from colder to warmer substances
Warm air holds less moisture than cold air
The Mpemba effect refers to the counterintuitive observation that, under specific conditions, hot water can freeze faster than cold. The other options describe unrelated or false phenomena.
Which of these statements about goldfish is a myth?
They have a memory span of only three seconds
They can be trained to perform simple tasks
They can grow larger than their tank if given space
They have a lifespan of over ten years in proper care
Goldfish have demonstrated memory spans of several months in experiments. The belief that they remember nothing beyond three seconds is unfounded.
Which of the following statements about dogs is a myth?
Dogs see only in black and white
Dogs wag their tails to communicate
Dogs have sweat glands in their paws
Dogs can learn human words by association
Dogs have two types of color receptors and can see shades of blue and yellow, so they are not purely black-and-white vision. The other statements are supported by research.
Which of the following statements is true?
Both brain hemispheres communicate via the corpus callosum
People are either left-brained or right-brained
The left hemisphere controls the entire right side of the body
Only the right hemisphere processes visual information
The corpus callosum is the bundle of nerve fibers connecting the two hemispheres. Popular ideas about being strictly left- or right-brained are oversimplifications.
Which of the following beliefs is a myth?
Shaving hair makes it grow back thicker
Carrots are rich in vitamin A
Handwashing prevents disease spread
Regular exercise benefits cardiovascular health
Shaving hair does not change its thickness or growth rate; it only alters the hair's tip shape. The other statements are well-established health facts.
Which statement about vitamin C is accurate?
Vitamin C cures scurvy
It prevents all viral infections
It dissolves bones in high doses
It is stored in body fat
Vitamin C deficiency causes scurvy, and supplementing it cures the disease. It does not prevent every viral infection, dissolve bones, or store in fat.
Which of the following statements is a myth?
Swallowed chewing gum stays in your stomach for seven years
Gum base is insoluble but passes through the digestive system
Chewing gum can help reduce ear pressure during flights
Most chewing gum contains sweeteners or sugar
While gum base is not digestible, swallowed gum typically moves through the digestive tract and is expelled within days. The seven-year claim is an urban legend.
Which of the following statements about dropping a penny from a tall building is true?
A penny reaches a terminal velocity too low to be lethal
A penny will accelerate with no upper speed limit
A penny will bounce back to the thrower with lethal force
A penny can cut through metal roofing on impact
Due to air resistance, a falling penny reaches terminal velocity around 25 m/s, which is far too slow to cause lethal injury. The other claims exaggerate its danger.
Which of the following statements about memory is supported by research?
Spaced repetition improves long-term retention
Memory works like an exact tape recorder
Cramming is the best way to store information long term
Long-term memories never change once formed
Numerous studies show spaced repetition strengthens memory consolidation over time. The other statements are misconceptions about how human memory operates.
Which statement about knuckle cracking is true?
It produces gas bubble cavitation that causes the popping sound
It damages cartilage and leads to arthritis
It always causes pain if done frequently
It increases grip strength over time
The popping sound arises from gas bubbles collapsing in the synovial fluid. There is no conclusive evidence linking cracking knuckles to arthritis or permanent damage.
Which of the following beliefs about blood donation is a myth?
Donors can contract HIV from the donation process
Donors receive free health screening
The body replenishes lost blood volume within weeks
Regular donation can reduce iron overload in some donors
Sterile, single-use equipment makes transmission of HIV during donation virtually impossible. The other points describe real outcomes or benefits of donating blood.
Which of the following statements about the speed of sound is accurate?
Sound travels faster in steel than in water
Sound travels at 300,000 km/s in air
Sound cannot travel through gases
Sound speeds up in colder air
Higher density and elastic properties make sound waves move faster through steel than water. Sound in air travels near 343 m/s, not hundreds of thousands of km/s, and slows in colder air.
Which of the following statements about fuel types is false?
Adding water to gasoline increases engine power
Premium fuel is only necessary for high-compression engines
Engine efficiency decreases at high altitudes
Diesel engines ignite fuel through compression
Water in gasoline will prevent proper combustion and damage the engine. Premium fuel is designed for higher compression ratios, efficiency drops at altitude, and diesel engines rely on compression ignition.
