Learn about bridge design from some of MIT’s Civil Engineering students, then put your knowledge to the test in a competition to build the strongest bridge. We’ll provide materials and feedback on your designs, and at the end of the class, we’ll see which bridge can hold the most weight.

Learn more about the measures used to determine water quality in the Charles river and other bodies of water. Then take a trip outside to the river to perform some simple tests yourself. (Make sure to bring warm clothes!)

Step right up! Come get your hands wet tackling the most challenging challenges, solving the most mysterious mysteries in the known hydrosphere! This year's Hydro Carnival features three midway games that test your brain and braun. Do you have what it takes to win a battle against water with nothing but your lungs? Can you explain the unexplainable and reason what makes a "special" ice cube sink? Are you capable of great magic by creating a cloud in a bottle that doubles as a rocket? You'll perform three hydrology experiments to answer these questions and learn about the physics of water. So come on down to the Hydro Carnival where great prizes are to be won and great science is to be discovered! 1) Lungs of Steel 2) A Sinking Feeling 3) Cloud in a Bottle Rocket Come for the prizes or come for the thrill, but be ware...you might learn something!
