How Richard Branson's team created the world's largest hot air balloon in order to undertake a daring crossing of the Pacific Ocean. Maths - Shape A Twig Math Film. Reinforce and extend the learning required by the curriculum. Twig’s...

We compare the density of oil, salt water and fresh water using displacement tanks. Equally weighted measuring cylinders are placed into the three liquids and the amount of water displaced is collected for comparison. Physics - Forces -...

We inflate a rubber glove using the gas produced during a neutralisation reaction. Bicarbonate of soda is added to vinegar in a beaker covered by a rubber glove and it expands. The gas is used to extinguish a flame, showing that it is...

We create an underwater volcano by placing a conical flask of hot coloured water in a tank of cold water. The hot coloured water rises through the cold, demonstrating convection. Physics - Energy And Radioactivity - Learning Points....

Scientists believe there is a supermassive black hole 26,000 light years away at the centre of our Galaxy. But how do they know, when they can't see it? Physics - Universe - Learning Points. Black holes are formed when massive stars...

Learn why steel boats float with this quick buoyant force demonstration! Discover how the average density of steel boats is less than water, allowing them to stay afloat.

By the end of this learning object, the student will be able to: Recognize the concept of matter. List the properties of matter. Compare among the three state of matters.4426

Delve into the fascinating world of ocean currents, from surface flows influenced by wind patterns to deep currents driven by water density. Learn about the crucial role of currents in regulating global climate and distributing...

In the 1980 s, the United States Air Force pioneered a Big Idea. It was a new method of navigation via satellite, predicted to have significant benefits for civilian, as well as military transportation. It was then called NAVSTAR, but is...
