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

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.

These granules are a special water-absorbing chemical called sodium polyacrylate ... The sodium polyacrylate will change into a gel as it absorbs the water. The gel will slowly rise in the cup. That’s ...

Instead, the atoms rearrange themselves to form new chemicals. This is known as a chemical change. The other kind of change in chemistry is a physical change, which is when a substance changes ...

In the second experiment, they change the concentration of the acid. Predict their conclusions from both experiments, and explain your predictions using ideas about collisions between particles.

But as far as their structure is concerned, these RNAs all share the same basic single-stranded chemical structure with, in some cases, higher-order structures obtained through complementary base ...

Sustainability and climate change should be included in the way chemistry is taught - so we brought key stakeholders to discuss what the best way to do that looks like.
