Martin & Sylvia: Nine and Seven
It's Martin's ninth birthday — the brother and sister are growing up! What is it like to be nine? And what can "sevens" do? Martin finds himself interested in complex magnetism experiments while Sylvia embraces the challenges of leadership. Through science clubs, wilderness adventures, neighborly parties, and family time, Martin and Sylvia lean into their new ages. Together, they learn more about themselves, what they're capable of, and what makes life even more joyful.
