Keep kids’ brains active: Are your stir-crazy kids starting to act like animals? In honor of primatologist Jane Goodall’s 86th birthday on Friday, have children take this Quiz Whiz to test their smarts about chimps, gorillas, and other apes. The Nat Geo Kids website has tons of other learning resources for parents like science experiments, personality quizzes, animal facts, and homework tips. And our partners at Dr. Cool have a great kit for making slime.
