observation and research
OBSERVATION AND RESEARCH
  • May be done ___________ or ____________you pose a formal problem
    • Gives you a ____________ to answer or
    • Helps you formulate a _______________
problem purpose question
PROBLEM/PURPOSE/QUESTION
  • This what you want to solve.
  • Research may __________ to this problem
  • Research may be done after problem is formed.
  • Sample problem: _________________________________________________________________________________________________________________________________
hypothesis
HYPOTHESIS
  • Prediction based on prior knowledge
  • FORMAT: If ____________ then _____________ because ________________.
  • Example:
    • Using the questions from the slide before, lets make a hypothesis.
    • Hypothesis: IF _______________________________ THEN___________________________ BECAUSE ____________________________________
variables and controls
VARIABLES and CONTROLS
  • The factors that you are ___________________in an experiment
  • INDEPENDENT VARIABLE:the one factor you ________________ in your procedure
  • DEPENDENT VARIABLE: the factor that changes due an independent variable being changed
    • EXAMPLE: __________________________________________________________________________________________________________
  • CONTROL: this is the experimental set-up where ____________________________!
slide6
DATA
  • Observations, Measurements, Calculations, Drawings, etc…
  • Presented as:
    • __________________________
    • __________________________
    • __________________________
    • __________________________
  • Any figures (charts, diagrams, etc…) should be inserted into the document under this section.
  • This is also where you show work for calculations.
slide7

GRAPHING DATA Example

ALWAYS HAVE A _____________ THAT IS RELEVANT AND TELLS THE READER WHAT THEY ARE LOOKING AT

Y-AXIS is for the ________________ variable.

Notice both a title and the UNITS used to measure are present!

  • Analyzes errors
    • What went wrong in procedure or with materials?
      • This is not: ______________________________________.
    • How did this malfunction change data? (BE SPECIFIC)
      • Did it increase numbers? Decrease numbers? Spread them out? Clump them together?
  • Makes new predictions
    • What would you change in your material list or procedures next time?
    • What do you hope to see (data-wise) with these changes?
