Re: [Phys-L] motion lab



The standard modeling ohysics approach... (grammar & spellling will suffer due to touch screen)
Talk to students, socratic discussion about:
Determine what you can measure about buggies motion. With our equipment, t and x.
Which wil you control which observe.
What goes on x or y axis.
End socratic dialogue with kids either a) set time intervals and measure position or b) vice versa.
When kids are going to collect data, have some stary at origin and go in positive direction, some in negative direction, some start at positive position some negative.
Kids plot data on whiteboards.
Present equation for line.
What does slope represent.
Hiw could you change slope.
What does y inter ept represent.
Hiw could you change it

Works really well.
Good luck.

Does anyone do a "constant velocity" lab? Like using constant velocity
cars (Tumble Buggies)? If so, what do students measure (just d and t?)? Do
they make a graph? Cookbook or open-ended? Is it more about measuring than
finding the actual speed?

I'm looking for something low tech (for high school) and meaningful. Just
stopwatches and meter sticks. Wanting some ideas to make a "basic" lab
like this interesting...
