Slide 8 - Tekstslide

2. Make a workplan
How can I get the answer to my research question?
- By viewing or counting something
- By doing an experiment


Method
List of supplies


Slide 9 - Tekstslide

Workplan
                                     Sample (steekproef)

                                     Quadrat (proefvlak)

Slide 10 - Tekstslide

- Counting (how many butterflies are there in my garden?)

Slide 11 - Tekstslide


- Experiment: - careful test of a piece of 'reality'
