  1. Ecology Holland Part 1

  2. Experiment 13: soilprofile Question: Which types of soil are in the ground? Hypothesis: we expected te lowerlayers of ground to be more wet and more claylike. Whichmaterials • drill• piece of white plastic• Tape measure• Sandwich bags• blackmarker

  3. Results: Conclusion: Our question has been answered cause we have learned the different layers. We also accept our hypothesis

  4. Experiment 14: soildetermenation Question: which type of ground? Hypothesis: we expect the ground to be clay like. Conclusion: the ground we examined seems to be “vaaggrond”. We accept the hypothesis, the soil is like clay.

  5. Experiment 19 organic matter content Question: which percentage of the soil sample willburn and begone. Hypothesis: we expectthat half of the sample willburn and that we will have only half of it. material : • glow spoon • soil sample • Bunsen burner • Scale

  6. Results: Conclusion: The question is answeredbythoseresults, we accept our hypothesis causeabout half of the sample has burnt.

  7. Experiment 20: grainsize • Question: What size of the grain? • Hypothesis: We expect much variation • Material: - soil sample - sevenset

  8. Results: • Conclusion:There is much variation in the grain size.The hypothesis was right.

  9. Experiment 21: pH-rate • Question: What is the pH-rate? • Hypothesis: We expect just above 7 • Material: - soil sample - glass - pH-counter • Conclusion: The pH-rate is 7,84, so we were near to this one
