📅 Wann ist meine Klasse dran?

Die genauen Termine zu den einzelnen Projekten findest du immer auf den jeweiligen Unterseiten.

Dort steht zum Beispiel:

welche Klassen teilnehmen
wann die Workshops stattfinden
was ihr vorbereiten müsst
welche Materialien wichtig sind

👀 Warum ist das wichtig?

Viele Dinge im Netz sind hilfreich, spannend und praktisch.
Gleichzeitig gibt es auch Herausforderungen: zu viel Bildschirmzeit, Streit in Chats, Kettenbriefe, unangenehme Nachrichten oder unsichere Apps.

Medienprävention soll dir helfen,

gute Entscheidungen zu treffen
Risiken besser zu erkennen
dich selbst und andere zu schützen
im Alltag eine gesunde Balance zu finden

🤝 Wenn etwas passiert

Du musst Probleme im Netz nicht allein lösen.

Sprich mit jemandem, wenn dich etwas belastet, zum Beispiel:

einer Lehrkraft
der Schulsozialarbeit
deinen Eltern oder Erziehungsberechtigten
einer Vertrauensperson in der Schule

Wichtig ist:
Hilfe holen ist kein Petzen, sondern richtig.

Hinweis

Diese Seite wird nach und nach ergänzt, wenn neue Projekte oder Materialien dazukommen.
