This week, campers investigate two very different—but surprisingly similar—worlds: the circulatory system inside the human body and the pipe networks that run beneath our cities. Through targeted models, comparisons, and problem-solving challenges, they’ll explore how fluids move, how blockages create issues, and why thoughtful design matters. By the end of the week, hearts, blood vessels, and city pipes start to look like variations of the same big idea: systems built to keep things moving.
