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

UCLA doctoral student Yilin Wong noticed that some tiny dots had appeared on one of her samples, which had been accidentally ...

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.

The reaction can only use the oxygen that is already in the jar ... Since there is a flame in this experiment, be sure that a teacher, parent, or other adult works with you. Wear goggles when doing ...

The experimental analysis of the chemical reactions is the basis for a fundamental understanding ... The department has a comprehensive repertoire of experiments at its disposal for the detailed ...

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 ...

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 ...

Watch as common household ingredients create a fascinating chemical reaction that produces a growing "snake" of carbon. This experiment demonstrates decomposition reactions, gas formation, and the ...

The third process we tried was a chemical reaction called the thermite reaction ... Before you try the following experiment, make sure that you are wearing protective glasses and latex or rubber ...

While the carbon snake experiment is generally safe and uses common household items like sugar and baking soda, it still ...

Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. Evidence of chemical reactions includes a large temperature change ...

A study shows that electrical charges in sprays of water can cause chemical reactions that form organic molecules from inorganic materials. The findings provide evidence that microlightning may have ...
