Can Climate Change Make Lightning… Supercharged?
The oceans absorb a lot of CO2, leading to a variety of effects like ocean acidification. But you might not expect one of those effects: stronger lightning strikes.

Water Resources
In this video Paul Andersen explains how water is unequally distributed around the globe through the hydrologic cycles. Seawater is everywhere but is not useful without costly desalination. Freshwater is divided between surface water and...

An Introduction to Solid State
An Introduction to Solid State A solid is a form of matter with rigidity, a definite shape, and a definite volume. It differs from gases and liquids, which have fluidity determined by the relative free motion of their molecules. Solids...

Bouncing Eggs
We use vinegar to remove the shells from eggs without breaking them. Two eggs are placed in a beaker of vinegar, but one is half coated with clear nail polish. The exposed shells dissolve over time and the eggs swell as more water moves...

Kiwi Fruit DNA
We extract the DNA from a kiwi fruit by mashing it with detergent liquid, salt and water. The mixture is then filtered and incubated before a layer of chilled ethanol is added. The jelly-like DNA can then be extracted. Biology - Cells...

Distillation of Ink
We use distillation to remove the water from ink. The ink is heated in a conical flask with a delivery tube running to a beaker. The water has a lower boiling point and so it evaporates before the ink. The water condenses as it travels...

Endothermic Reaction
We demonstrate an endothermic reaction by mixing hydrated barium hydroxide with ammonium thiocyanate. When these two solids react they take heat from the surrounding air. Chemistry - Reactions - Learning Points. Breaking bonds takes in...

Metal Extraction
We extract copper metal from copper chloride solution using electrolysis. The electric current causes copper to form at one electrode and chlorine gas to form at the other. The presence of chlorine is tested using blue litmus paper....

Clearing Oil Spills
We investigate the effectiveness of different methods to clear oil spills from water. First, we try to burn the oil in a sample of water using a gas lighter but there is no effect. Next, we break the oil up using detergent but this does...

Oscillating Colour Change
We use three chemical solutions to create an oscillating reaction. The three different solutions are mixed using a magnetic stirrer and the colour changes from clear to amber to dark blue. This pattern repeats as the concentrations of...

Inflating Glove
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...

CompTIA A+ Certification Core 1 (220-1101) - Virtual Memory
Running out of memory is something we try to avoid. All operating systems use virtual memory (or RAM), a part of your mass storage set, to act as (very slow) memory in case your real memory runs out. This clip is from the chapter "Book...
