Coaster Car Challenge Slow Down…you are already moving at 18 km/hr
T0-Do • Write your first equation in your equation chart: • Term: Speed • Definition: Distance traveled per unit time • Equation: S = d/t • Triangle: • Units: meters per second (m/s) • Reflect on your October Sky lab write-up or your science fair display. What was done well and what could you do better? Write one goal for improvement for your next lab report that we will start today. • Grab a calculation worksheet from the side counter and give it a shot…do as many problems as you can in the next few minutes • Anything you don’t finish is homework (due next class) d t S
Criteria & Constraints • Big Challenge: Design a vehicle that will go fast, far, straight, and carry a load. • Criteria(measurable & quantifiable) • Go Fast • Go Far • Go Straight • Carry a Load • Travel over different terrain • Must travel at least 5 meters • Have a Michael Phelps mindset • Rules • The boss is always right • If the boss is wrong…see rule #1 • Constraints • All materials used must come from home • Must be built with parts that are not originally designed for vehicles or moving objects • Maximum dimensions of your vehicle: • Length: 25 cm Width: 10 cm • No electronics • Gravity is the only external force that can act on the vehicle after it is released. Any additional forces must come from the design and internal workings of the vehicle itself. • The vehicle cannot leave the ground when in motion • Vehicle design must be practical and realistic for completion 1 month from now
Coaster Car Challenge • Goal: Design an experiment that turns our big question into a quantifiable measurement and practice with coaster cars • Fast ? Far? Straight? • Discuss classroom norms for accurate measuring techniques • What tools will we measure with? • How can we be consistent as a class? • Start a rough draft lab write up with all necessary sections to explore the following variables • Independent Variable: Ramp Height • Dependent Variables: Speed, Distance, Veering • In order to begin your lab testing next class you need to have an experimental design complete in your journal • Book Resource: pgs ???
