Budding scientists will grasp tough physical science concepts through informative and easy-to-understand explanations - from the structure of atoms to the properties of liquids. This series builds the confidence of even the most reluctant readers.

Mixtures and compounds are everywhere. The ocean is a mixture, and so is chicken noodle soup. Rust is a compound, and so are fireworks. Real-life examples bring this concept to life.

Get insight into a matter that has no volume and can be impossible to see or feel. Learn about diffusion and how gases take on the shape of their container.

From the concept of flow and volume to the molecular structure of a liquid, examine the physical properties of a liquid and what makes it different from a solid or gas.

From the concept of flow and volume to the molecular structure of a liquid, examine the physical properties of a liquid and what makes it different from a solid or gas.

Did you know that people need salt to live? And that there are many, many kinds of salt? Learn their properties and how people use them.

Much of the matter that we encounter every day is in the solid state. Explore the physical properties of solids and how to distinguish them from gases and liquids.

From rising bread to exploding fireworks, chemical reactions play an important role in our lives. Learn how atoms combine and rearrange to form new substances.

Explore the four elements - carbon, nitrogen, oxygen, and hydrogen - that are the major building blocks of life on Earth.

The periodic table of elements has existed since 1869, but scientists are still adding to it today. Discover a wealth of information about the table and the elements that make it up.

Trace the remarkable evolution of scientific instruments from the compound microscopes of the 16th century to the miniscule microscopes being developed today.

Learn what properties distinguish substances in the three basic states of matter -solid, liquid, and gas - and learn what new states of matter are just being discovered.
