When public schools are out next week, here are some ideas of what to do with the kids throughout the five boroughs, from Presidents’ Day-themed scavenger hunts to botanical garden workshops to art workshops.

Presidents’ Day (Feb. 20) is a prime time to learn more about the country’s Founding Fathers. Throughout the school vacation week, the cultural institution’s children’s museum will host a series of events in honor of Presidents’ Day, including a presidential-themed scavenger hunt, crafts and, on select days, “living historians” portraying George Washington, John Adams, Thomas Jefferson, James Madison, James Monroe and more. Feb. 18-26, FREE with admission ($20 adults, $15 seniors, $12 students, $6 ages 5-13); 170 Central Park W., 212-873-3400, nyhistory.org

BROOKLYN: Explore a conservatory
