You should already know what a straight line, quadratic, cubic and reciprocal look like when plotted on a graph. In this video we will discover what the sin, cos and tan graphs look like and also exponential functions. You don't necessarily need to know the exact values that these functions cros
The climatic phenomenon known as El Niño is a disruption of the ocean-atmosphere system in the tropical Pacific that impacts weather and climate around the globe. An El Niño occurs every four to twelve years, causes die-offs of plankton and fish, and affects Pacific jet-stream winds, altering storm
Warm water fuels the tropical storms that ultimately form hurricanes. In this video segment adapted from NASA's Goddard Space Flight Center, learn how El Niño events—climatic anomalies that occur periodically in the Pacific Ocean—alter the course of atmospheric circulation and lessen hurricane forma

SOHCAHTOA, Pythagoras, sine rule and cosine rule and all things trigonometry actually have a lot of uses in “real life”. Such as working out distances to things, heights of buildings and mountains, navigation at sea. An important part of “useful” trigonometry are angles of elevation and depression.
There are some key angles that have exact values in trigonometry. The ones we need to know are 0, 30, 45, 60 and 90. In this video we will discover one method of remember what these values are - using a table. In the second part we will discover a different method (using our fingers) which you may p
Not every triangle is a right-angle triangle, so we can't always use Pythagoras and SOHCAHTOA to find missing sides and missing angles. We instead use the sine rule or the cosine rule. They can both be used to find either missing sides or missing angles in any triangle (right angle or not). Click h

How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How
