Coaster Car Challenge Slow Down…you are already moving at 18 km/hr

T0-Do Write your first equation in your equation chart: Write your first equation in your equation chart: Term: Speed Term: Speed Definition: Distance traveled per unit time Definition: Distance traveled per unit time Equation: S = d/t Equation: S = d/t Triangle: Triangle: Units: meters per second (m/s) 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. 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 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 dont finish is homework (due next class) Anything you dont 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. 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 1.The boss is always right 2.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 Goal: Design an experiment that turns our big question into a quantifiable measurement and practice with coaster cars Fast ? Far? Straight? Fast ? Far? Straight? Discuss classroom norms for accurate measuring techniques Discuss classroom norms for accurate measuring techniques What tools will we measure with? What tools will we measure with? How can we be consistent as a class? How can we be consistent as a class? Start a rough draft lab write up with all necessary sections to explore the following variables Start a rough draft lab write up with all necessary sections to explore the following variables Independent Variable: Ramp Height Independent Variable: Ramp Height Dependent Variables: Speed, Distance, Veering 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 In order to begin your lab testing next class you need to have an experimental design complete in your journal Book Resource: pgs ???
