Science simply defines matter as anything that has mass and occupies physical space or has volume. Your device is matter; what you stand or sit on is also matter; our beds are also matter; we too are matter. Everything around us here on earth can be described as matter because they satisfy the definition of matter. In this course, you will understand the composition of matter around you covering its atomic structure as well as protons, neutrons, and electrons. The course also explains the interaction between these different components in the formation of molecules, compounds, as well as isotopes and polymers. You will also understand transforming matter from one form to another while considering the varying properties of each form and the Law of Conservation of Mass. Successfully completing this course will equip you with knowledge on the science of atoms and their relationship with matter around us.
High School Chemistry: Measurements and Matter is a free online course designed for chemistry students and enthusiasts. It explains the correct methods of taking measurements of quantities in chemistry with accuracy, precision, and attached uncertainties. It also analyses the standardised dimensions and units of length, capacity, and weight or mass used in the metric system of measurements. Learners enrolled in this course will go through simple examples for unit conversion of different quantities measured in chemistry. They will also learn about the arithmetic of readings for various measurements common to chemistry. A good understanding of measurements discussed in this course is required for young scientists looking to go deeper into chemistry. Professionals and chemists can also enrol in this course for a quick recall of basic measurement skills and dimensional analysis. Chemistry teachers and tutors in schools will learn better methods of relaying concepts surrounding scientific notations.

All humans are made of matter. On a microscopic level, we exist and survive based on the unimaginable number of chemical reactions of atoms within us. Studies have estimated that a single human being carries roughly seven thousand quadrillion atoms within them! Imagine the number of chemical reactions these atoms go through every second within your body. Pause for a moment and think about where to start your exploration of biology and chemistry? Also, ask yourself the important question of what chemical reactions occur within your organs like your heart, stomach and lungs? By taking this free online course, you begin your journey to answer questions about living and nonliving things around you. Begin your learning journey on measurements of quantities and matter in chemistry!
