In this video, the Oryx teaches children about the importance of moderation in various aspects of life. Through the story of Basil, a boy addicted to video games, they learn about balancing leisure activities with responsibilities,...

Kites fly because of the aerodynamic forces of lift and drag. The difference in air pressure on the top and bottom of the kite creates lift. The drag is created by the friction of the air flowing around the kite. The lift balances the...

Your nervous system is why you can see this video, scratch your neck, feel hungry and ask yourself, Who am I? The human nervous system is a fascinating system with 86 billion neurons and about the same number of glial cells. The main...

Muscle trembling during weightlifting or intense exercise is a result of muscle fatigue. Muscle fatigue, in simple words, refers to the state when our muscles get tired. To understand this phenomenon, it is better to first understand...

Whether fish get thirsty depends on the fish you look at. Fish that live in freshwater have different physiology to deal with their environment than fish in salty seawater. These physiological differences dictate whether fish need to...

Although kidneys are clearly important for survival, they are not essential, and this is particularly true if only one kidney is present. Some people are born without one of their kidneys, a condition called renal agenesis. Some other...

While the population statistic is around 102 men : 100 women, the birth rate is more skewed. Approximately 107 men are born for every 100 women. However, over time that number seems to even out. Over the course of millions of years of...

The urge to jump or high place phenomenon apparently springs from a distortion of our perceptions. Lab tests have shown that people estimate disgusting things, such as feces, to be closer than they really are. Another example is...

Carrying a pole helps the walker increase their rotational inertia, which aids in maintaining stability while walking over the narrow rope. The pole also adds more weight below the center of gravity of the walker, which is another bonus...

We use a plumb line and hook to find the centre of gravity of an irregularly shaped piece of card. A hole is punched in the card and it is suspended from the hook. A plumb line is used to let us draw the vertical line under the hole on...

We use a Van de Graaff generator to investigate static electricity. The generator is turned on and we see a spark move between the two domes. We then place a wig on the main dome and see the hair rise as the charge builds and the hairs...
