With the germination dishes, simple germinating experiments with different seeds and under different conditions can be carried out.
With the germination units, the water absorption or swelling and germination of seeds, growth and development of plant parts and their reactions to specific environmental factors can be observed.
The students discover that the roots force their way through the slits on the bottom of each cell and grow in a downward direction (positive geotropism) and that pea stems and leaves and the stalks of cereals grow in an upward direction (negative geotropism).
Experiments to determine the water absorption and water storage capabilities of peat and peat moss (sphagnum).
With the transparent air permeable lid the multi purpose container is especially well suited for short term captivity and observation of small animals, beetles and insects (e.g. maybugs, flies or grasshoppers).
Experiments demonstrating the surface tension of water (pin, razor blade, water strider).
Comparison of the leaves of one type of plant taken from different locations (dandelion, plantain, lady’s smock).
