Position/Time graph story problems intro

Postby Tom_DeVries » Fri Oct 21, 2011 7:47 pm

Hi everyone,

Just working through some of my lessons in preparation for using them in second semester.

This forum doesn't (yet) seem to be a place where there are enough of us to generate some discussion and provide feedback on lessons, but I'm hoping!

This is a lesson using some animations to talk about position time graphs.

It's long, but hopefully "interesting".

If anyone does look at it, feedback is welcomed!

Below is a link to the file in my Dropbox folder.

Tom,

I'm actually really impressed by that 7-Eleven logo --- it looks pretty darn good for a freehand drawing! :D

One thing that might help with the models is to use Appearance -> "Labeled" for the seconds controller. That way, students wouldn't have to expand the animation to see the value for the slider (even though you made a point to remind them about the animation controls at the beginning of the presentation, I thought they might forget that).

And you can use free-form input to do the unit conversion really easy: just type an equal sign, then something like "5km/hour to meters/second," and evaluate to get an answer.

Overall, though, I found this to be a fun lesson and one that I think your students will enjoy.

Regards,
Michael
