Formations of teams

Critical Question: What enterprise traits would be most needed for cart construction and motions and forces trials?

Revise enterprise traits.
In groups students prioritise traits in response to question and develop arguments to support their decisions.

Groups share responses, then reflect and review until class agreement is reached.

Team formation:
Students examine Enterprise wheels (profiles) and physically place themselves where they would best contribute in a team (eg Risk Manager, Team Person…). Where a student has more than one area of expertise, s/he should go to the trait least represented in the class. Teams are formed on the basis of trait representation.

Building a Test Ramp:

Critical Question: What happens to a vehicle when there’s very little friction?

Using materials provided and an on-line procedure, construct a test ramp for your team’s air-cart trials

Coasting Tests:
Race your air-carts by rolling them down the ramp. Order the carts from the one with the least friction to the most. Observer the motion of the acrobat during the race.

Decide on a way to test the relative friction of the carts. Without using the motor or propeller. What makes you think that yours is a fair test? Record your explanation on the hand-held computer.

Share findings by beaming your recordings to others and reading and discussing their findings (clarifying questions and responses may also be beamed between groups)

Race the air-carts, using motors, propellers and fresh batteries. Explain on your palm-helds what you think accounts for the variations. Share findings as before.

Moving at a Constant Speed:

Critical Question: What can be learned from position and velocity graphs of a moving cart:
*Can you tell exactly how far or fast your cart is moving without any measuring tools?
*How would you know its speed at any time?
*Could you identify when it is slowing down?
*Would it be more useful to know its speed or position at any given moment?

Discuss these questions with your team and record ideas on the palm-held computer.

Attach the SmartWheel probe to one air-cart (with the least friction). Connect the SmartWheel to the interface box and the palm-held. (devise a way to prevent the wire from pushing or pulling the cart).

Start the software (CC Probe) and observe the position (distance-time) graph as you move the cart along a flat surface without the motor going. Interpret the graph to explain the motion of the cart, and where on the graph the cart is moving at a constant speed.

Challenge: Keep your cart moving at a constant speed for 30 seconds. Record on your palm-held a method that you predict will be successful. Test the method and observe the movement of the acrobat during each trial. Save the data, together with an explanation to prove constant speed for 30 seconds. Share this with via beaming.

Slowing Down:

Critical Question: As above

Using the ramp, design a method of slowing down the cart without the motor running, over at least a 20 second period as it rolls across a rough surface. On the palm-held, describe or sketch how this could be achieved. Test the theory and save the data.

How does the position graph show that the cart slowed down Was the slowing-down rate constant? If not, when did it change). Explain your reasoning on the palm-held.

Speeding Up:
Using the ramp, design a method of speeding up the cart with the motor running, over at least a 20 second period as it rolls across a smooth surface. On the palm-held, describe or sketch how this could be achieved. Test the theory and save the data.

How does the position graph show that the cart increased in speed? Was the rate of increase constant? If not, when did it change). Explain your reasoning on the palm-held.
