Volume = 30 L Volume = 50 L

Density = 2.7 g/L Density = 2.7 g/L

    1. Symbols & Equations

a. Symbols => Each symbol stands for a very

specific property or concept. These quantities represent a number and a unit.

    1. Equation => A statement that describes a

relationship where the quantities on one side of the equal sign are identical to the quantities on the other side.

    1. Describe a property
    2. Define a concept
    3. Describe how quantities change


5. Proportions

    1. Constants
    1. Graphs















  1. Scientific Method


Formulate a Hypothesis

Design a Controlled Experiment

Prior Knowledge Collect Data

Interpret Data

Draw Conclusions


    1. What is a Hypothesis?
    1. Verifiable vs. Falsifiable Hypotheses
    1. Specific vs. General Hypotheses

In science, you continually attempy to prove your hypothesis is incorrect. Scientific statements are tentative!

    1. What is a Theory?
