Chemistry 101 intro

Chemistry

The study of the composition of chemicals, their properties, and the reactions they undergo

Chemical

Substance that has the same/different composition no matter where it’s found

3 worlds of chemistry

Modeled in 3 ways Macroscopic, symbolic, particle diagram

Macroscopic

How we sense matter we can see or touch

Symbolic

How can we symbolize matter using abbreviations

Particle diagrams

How we visualize matter and its interactions

observation

Qualitative (descriptive) or Quantitative (numerical) measurement

Hypothesis

tentative explanation of the observation

Experimentation

controlled testing of hypothesis

Theories and Laws

explaining how and predicting impacts of observations, respectfully

Scientific method

isn’t a specific set of steps, so the CER method is used instead (C)laim (E)vidence (R)easoning

Patterns in data

Finding patterns in data tables or in a graph is the creative side of science, they can help predict/plan what will happen next

Interpreting graphs

Graphs allow you to visualize patterns of numerical data

3 successes in chemistry

Curiosity, Calculation, commitment

Curiosity

Ask why matter behaves in a certain way and use your imagination to spark interest

Calculation

One of the most important tools of science involves the measurement and manipulation of numerical data

Commitment

Studying chemistry requires hard work you’ll be rewarded for
