About Course

Chemistry helps us understand the composition of matter and the changes that occur when substances interact.Explore topics ranging from states of matter and solutions to atoms, chemical reactions, metals, and fuels by selecting a topic below.

Course Content

States of Matter
Matter is everything around us and can exist as solids, liquids, and gases.Explore how particles behave and how substances change state by selecting a quiz below.

Solutions and Crystals
Investigate how solutes and solvents combine, the factors that affect dissolving, and the formation of crystals. Select a quiz below to test your understanding.

Separating Mixtures
Mixtures contain substances that can be separated without changing their chemical properties.Choose a quiz below to explore the methods used to separate different mixtures.

The Atom
Everything around us is made of atoms.Discover how atoms are structured and how their particles determine the properties of matter by choosing a quiz below.
