Engineer and Invent Festival @ Marshall Elementary
Mission Graduates and the Lawrence Hall of Science present the Engineer and Invent Festival at Marshall Elementary in San Francisco.
From www.lawrencehallofscience.org:
"Step into the shoes of an engineer as you investigate, experiment, and develop solutions to real-world problems. Tweak the blades on a wind turbine to efficiently harness the power of the wind. Construct a working hydraulic arm to explore the strength of water-powered machines. Flip the switch on the world of electricity, as you explore circuits and bring your motorized creations to life. Build bridges, towers, or whatever you can imagine with metal, paper, or wood. Stations include: hydraulics, wind turbines, circuitry, wobble bots, bridges, Keva planks, and bionix blocks."
