It sounds like a Jewish mother’s nightmare: a preschool class held outdoors in the desert. But parents in this remote Israeli town drop off their children at Gan Keshet every weekday during the school year, setting them free to cook on a campfire, whittle sticks with switchblades and search for scorpions. Class goes on rain (rare) or shine (intense). Gan Keshet, which means “rainbow kindergarten” in Hebrew, is the country’s first “forest kindergarten” – and it’s public. Thanks to local media coverage and word of mouth, parents have lined up to enroll their children and educators across Israel have sought to emulate the model.
