On Wednesday, the anniversary of the uprising and the founding of the kibbutz, senior Israeli Army officers and a group of Jewish and Arab educators attended seminars and toured the museum’s exhibits, some of which are based on documents and objects that the founders brought with them from Europe.

The museum does not shy away from dealing with Israel’s own inner conflicts. Its Center for Humanistic Education, founded in 1995 by Raya Kalisman after she spent a year at the United States Holocaust Memorial Museum in Washington, runs a six-month program for Jewish, Arab and Druze high school students, mostly from northern Israel. The program encourages the students to confront the complexity of their identities as citizens of the country.

Reflecting that complexity, Kibbutz Lohamei Hagetaot was established in the vicinity of Al-Sumeiriya, a Palestinian village that Zionist forces occupied and destroyed in the 1948 war over Israel’s independence, turning its inhabitants into refugees.

“Most Arabs here perceive themselves as victims of the Jews,” said Yariv Lapid, the director of the center, adding that any student searching online for information about the Holocaust in Arabic is likely to encounter a lot of denial. Over time, he said, the program challenges them to examine their own communities, which are often conservative and may be intolerant, for instance, of homosexuals.

Ms. Sternberg, who was born Devora Zissel Bram, grew up in a religious household in Czestochowa and was 15 when World War II broke out. She said she lost her faith in God after her parents, younger sister and brother were taken to the Treblinka death camp and killed. She was taken with other girls for forced labor in a Nazi arms factory. She fled to Warsaw as the Soviets approached, to avoid being taken to Germany.
