If you take a closer look at the topic of "weather", you will inevitably also encounter the fascination of dewdrops. Here are two very simple ideas.
That would be a suitable blanket! (Does it exist to buy!)
Or you could paint a large sheet on a paper.
A bowl with glass nuggets.
Provide both and offer to the child.
The "dewdrops" lie on the leaves. So the child can now also freely distribute the drops on the leaf.
The whole could certainly be preceded by a targeted observation in nature.
It is just as interesting when you look at pictures with dewdrops on leaves, such as these.
Fill a grappa glass or a small bowl with water and take a bibette.
Put a large (dry) salad leaf on a tray.
Now you can start. Pull the bibs full of water and try to place small drops on the salad leaf.
This is a good fine motor exercise. It promotes the dosage of strength, patience and sensitivity. Rather an offer for kindergarten children. Try it yourself!
