  1. Observe State the Problem Hypothesis Experiment Gather Data Analysis Conclude Communicate Predict Theory Law Scientific Method

  2. Infer To deduce in a logical manor from evidence

  3. Independent Variable In an experiment, the variable that the experimenter plans to change.

  4. Dependent Variable In an experiment, the variable whose value depends on the independent variable.

  5. Pure Research A type of scientific investigation that seeks to gain knowledge for the sake of knowledge itself.

  6. Applied Research A type of scientific investigation that is undertaken to solve a specific problem

  7. Technology The practical use of scientific information

  8. Model A visual, verbal, or mathematical explanation of how things occur

  9. Chemistry The study of matter and the changes that it undergoes.

  21. Le Châtelier’s Principle States that if a stress is applied to a system at equilibrium, the system shifts in the direction that relieves the stress.

  22. Ernest Rutherford Used the Gold Foil Experiment to prove existence of protons and that atoms are made of mostly empty space.
