Why Do Bees Buzz?

A bee's wings makes it buzz. When an insect flies, the size of its wings and the speed of their flapping affect the sound they make. Small wings push against less air than big wings do, so they have to beat faster in flight.

Why Do Stars Twinkle?

The scientific name for the twinkling of stars is stellar scintillation (or astronomical scintillation). Stars twinkle when we see them from the Earth's surface because we are viewing them through thick layers of turbulent (moving) air in the Earth's atmosphere.

Why Do I Feel Dizzy When Spin? 

 Each hair is connected to a nerve cell that carries signals to the brain. When the head moves, the fluid sloshes around and bends the hairs. As each hair bends, it makes its nerve cell send a signal, telling the brain about that movement. When we spin around, the fluid starts spinning, too.

Why Does Hair Turn Grey

As we get older, the pigment cells in our hair follicles gradually die. When there are fewer pigment cells in a hair follicle, that strand of hair will no longer contain as much melanin and will become a more transparent color — like gray, silver, or white — as it grows.

What Causes Thunder?

Thunder is the sound caused by lightning. Depending on the distance and nature of the lightning, thunder can range from a sharp, loud crack to a long, low rumble (brontide). The sudden increase in pressure and temperature from lightning produces rapid expansion of the air surrounding and within a bolt of lightning.

Why Do We Have To Sleep

Researchers have also shown that after people sleep, they tend to retain information and perform better on memory tasks. Our bodies all require long periods of sleep in order to restore and rejuvenate, to grow muscle, repair tissue, and synthesize hormones.

Why Is The Sunset Red?

Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules. So at sunrise and sunset, when the sunlight travels a long path through the atmosphere to reach our eyes, the blue light has been mostly removed, leaving mostly red and yellow light remaining.
