Lesson 1about 30 min
Matter and its classification
Chemistry studies matter and its changes. Matter is a solid, a liquid or a gas, and it is a pure substance (an element or a compound) or a mixture (homogeneous or heterogeneous). Its properties are physical or chemical, and we measure them in SI units: mass, volume, density and temperature.

Lesson 2about 30 min
Measurement and uncertainty
Every measurement has some uncertainty. Scientific notation writes very large and very small numbers. Significant figures show how precise a number is, and they follow rules in sums and products. Precision is how close repeated readings are to each other, and accuracy is how close they are to the true value.

Lesson 3about 25 min
Units and dimensional analysis
A unit is part of a quantity. A conversion factor is a fraction equal to one, such as 1000 mL over 1 L, and units cancel like numbers. A chain of factors changes any unit into another, and checking the units of an answer catches a wrong setup.
