### Project Objectives, Guiding Questions and Standards

 Hydraulics Project   Objectives/guiding questions/skills/standards -Objectives             -Students will develop a strong understanding of buoyancy and be able to determine if an object will float or sink             -Students will be able to calculate and explain pressure             -Students will demonstrate understanding of conservation of energy and relate this understanding to the relationship between force and distance in the work formula   -Guiding questions             -What is buoyancy? Why do things float or sink? How do we experience buoyancy on a daily basis?              -What are hydraulics?  Why are they used? How can they multiply force?             -What is pressure?  How do we experience pressure is our daily lives?             -How does the engineering design process support effective design and innovation?             -Required/built skills             -Students will calculate surface area and volume of 3 dimensional figures             -Students will use a scale to measure the mass of different objects             -Students will calculate density from mass and volume (d=m/v)             -Students will calculate the force of gravity (f=ma) (a=9.8m/s2) -Students will calculate pressure (p=f/a) -Students will measure the radius and calculate the area of a circle (a=pr2) -Students will convert from N/m2 to psi -Students will use and understand the engineering design process             -Teamwork and communication -Mass standards             -Engineering 3.2, 3,3             -Math skills                         - Solve simple algebraic expressions                                     - Measure with accuracy and precision                         - Use both metric/standard international
