Living nature

Topic: Soil and stone
Subtopic: Indicator species
Age: 7 - 12
Holistic Planning: Hand
Details: Experiment with changing the soil conditions to see if that affects the plants which grow there spontaneously (e.g. in a grassy area with small rushes (Juncus species) growing in a straight line this may be due to soil compaction. One could dig a section in the row and leave another area untouched. Return months later to see the changes in what plants are growing spontaneously there).
