The chapters of a scientific report 
INTRODUCTION
background information/theory/observation, research question (?!) and well explained hypothesis
MATERIALS AND METHOD
Used materials, description of experimental setup, report on the experimental execution
RESULTS
processed data (graphs, tables), report of the observations/measurements
CONCLUSION AND DISCUSSION
results explained, statement of validity hypothesis, reflection on the entire process: are there factors that have influenced the outcome/data of your experiment? elaborate.

Slide 5 - Tekstslide

Preparation
  • Research usually starts with a question: the research question
  • Goal of the research is to answer the question
  • What do all questions have?

Slide 6 - Tekstslide

They end with a question mark!
Hypothesis
Expected answer to the research question
Often seen formats:
-Cause and effect: If....., then...
- Correlation: ....has a positive effect on...
- Differences: comparing two or more groups

Research plan
Different types of research:
Describing : collect data by observing
Experimental : testing hypothesis with experiment
- Control group
Developing : develop material/model/method

Slide 8 - Tekstslide

Deze slide heeft geen instructies

Designing experimental research
  1. Determine variable to be experimentally changed
  2. Design multiple groups:
    - Vary the variable between the groups
    - Try to include control group (eliminate variable)
    - Keep all other variables constant
  3. Explain what will be measured, when, and how

Slide 10 - Video

Deze slide heeft geen instructies

Analysis results
  • Displaying results in tables and graphs
  • Drawing conclusion from results
  • Comparing conclusion with hypothesis and analyse differences: hypothesis accepted or rejected
  • Conclusion = the answer to the research question

How would you improve this graph?

Slide 13 - Open vraag

Don't forget to use quantities and units, e.g. temperature in degree Celsius, time in hours, etc..
