Students kit Germination-Units


Topic Botany

  • Germination of seeds
  • Growth of plant roots stems and leaves.
  • Reaction of plants to light and contact stimuli
  • Winding and climbing of plants
  • Development of plants from the flower
    to the fruit
  • Importance of growth factors for plants such as soil, light, warmth, air, water, water pollution
  • Phototropism of leaves and stems
  • Geotropism of sprouts and roots
  • Swelling force of seeds
  • Transpiration of plants
  • Assimilation of plants

 
Topic Zoology
With the transparent air permeable lid the multi-purpose container is well suited for use as small aquarium or terrarium for a short term captivity and observation of small animals (small fishes, beetles, worms).
By observing small animals students become acquainted with their habits (movements, breathing, eating and behaviour).
 
Age 8-16
Materials for 12 work groups (for 24 children)

The picture shows a red carrying case equipped with various experimental equipment and accessories for educational purposes. It contains, among other things, transparent containers, pipettes and instructions for germination experiments.
The picture shows instructions for an experiment on the germination behaviour of different seeds and lists the required material, including germination trays, a pipette and pieces of cotton wool. The text also describes how to carry out the experiment with the individual
The picture shows three rectangular white containers as well as three cotton balls and a pipette with a red lid. These materials are probably intended for scientific experiments in the educational sector.
The picture shows several clear containers with compartments and some black rectangular plates on a green base. These materials are part of the experimental supplies designed for use in education.
The picture shows a selection of experimental materials in a red box with green foam. Among other things, you can see pipettes with red caps, yellow sticks and cotton balls that can be used for various educational projects.
The picture shows a colorful arrangement of experimental materials on green foam. Green components, red pipettes, transparent containers and a small yellow component are visible, all of which can be used for educational purposes.
The picture shows a red box with the label "Germination Devices" from the Cornelsen Experimenta class set. The box contains various devices that are probably used for experiments on plant germination.
The picture shows a page from a teaching material about germination devices, which describes experiments to observe the germination and growth of plants. Various experiments and materials for biology lessons are listed.
The image shows a page from a textbook with instructions for experiments to observe plant growth under light and dark conditions. Shown are a darkroom germination shadow and a schematic plant experiment.
The picture shows a set for experimental supplies with a red container and various accessories. The objects included are a black box with a lid, a pipette with a red handle and a piece of cotton wool.
The picture shows a black, square box with a lid and an opening on the side. In the background there is a red container with a label indicating that it is for experimentation.

experiments
  • 1 - Experiments with the germination dishes

    experiment "Experiments with the germination dishes"

    With the germination dishes, simple germinating experiments with different seeds and under different conditions can be carried out.


  • 2 - Experiments with the germination units

    experiment "Experiments with the germination units"

    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.


  • 3 - Growth of plant parts: roots and shoots (geotropism)

    experiment "Growth of plant parts: roots and shoots (geotropism)"

    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).


  • 4 - Botanical application of the multi purpose container without the germination chamber insert

    experiment "Botanical application of the multi purpose container without the germination chamber insert"

    Experiments to determine the water absorption and water storage capabilities of peat and peat moss (sphagnum).


  • 5 - Activities and experiments using the multi purpose container with the air permeable lid

    experiment "Activities and experiments using the multi purpose container with the air permeable lid"

    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).


  • 6 - Experiments with the multi purpose container without the air permeable lid

    experiment "Experiments with the multi purpose container without the air permeable lid"

    Experiments demonstrating the surface tension of water (pin, razor blade, water strider).


  • 7 - Flower and leaf press

    experiment "Flower and leaf press"

    Comparison of the leaves of one type of plant taken from different locations (dandelion, plantain, lady’s smock).
