Preparing to study chemistry
Welcome to the world of chemistry!
- Graphing slope-intercept form: Part of the fun of chemistry is running your own experiments. Once you obtain experimental data, you will need to know how to visualize and interpret the results.
- Quadratic formula: Knowing how to set-up and solve quadratic equations will come in handy when you learn about chemical equilibrium.
- Scientific notation: Since chemists are lazy and don't want to have to write out all the zeros in a number like 300,000,000, we instead write numbers using scientific notation. Understanding scientific notation will let you skip writing all those zeros too!
- Dimensional analysis: My number two rule for learning chemistry is to always always check the units. Dimensional analysis is a helpful tool for making sure the units of different quantities make sense in any scientific calculation.
- Significant figures: Scientists use significant figures to aggravate chemistry students (just kidding!) and communicate the precision of a measurement or calculation.
Physics and biology
- The scientific method: Scientists are constantly uncovering new information about how the world works. The scientific method helps us ask questions and design experiments to test possible explanations.
- Coulomb’s law: The force between charged particles can be used to explain the properties of matter down to the subatomic level.
