The film explains the concept of chemical changes, where two or more materials combine to form entirely different substances.

Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led to the discovery of beautiful spiral patterns etched on the surface of the semiconductor by a ...

Learn more about how these experiments show that those small electrical charges can trigger the chemical reactions necessary ...

Some chemical reactions change temperature, change color, produce a gas, or make a solid from two liquids. Try this reaction and see what it does! Pour 1 tablespoon of hydrogen peroxide into a cup.

Engaging kids with hands-on experiments activates multiple parts of the brain, which means they’re more likely to retain what they’ve learned. Children will actually watch a chemical reaction ...

Yeah, yeah. We know real friends do not need to be impressed. But why not wow them anyway with this ghost glove experiment? Even more impressive? They’ll learn about chemical reactions.

You could be asked questions about the apparatus, methods, safety precautions, results, analysis and evaluation of these experiments. There are two PAGs in the Chemical reactions section ...

Fireworks, explosives and fuels, on the other hand, all involve very fast and extremely exothermic chemical reactions. The first 'reaction' that we tried for our hand warmer involved dissolving ...

Most metals go through a chemical reaction when they are combined ... so cannot displace it from its compound. Displacement reactions can help us arrange metals into a reactivity series.
