I'm setting up the equipment and materials today for a CBL/graphingcalculator/data probe (actually, motion detector) lab.
It's a good lab, one that I've done before; the students collect the data on the velocity of a falling coffee filter, and compare it to the velocity of a falling book. Then, they have to find the acceleration of both objects.
It's a tough one for the students; they have to read the lab directions, and make sense of them (not always an easy task - some students HATE to read). Then, they have to apply the methods we used to calculate velocity and acceleration. It's a tough task, as many students are not great with thinking through multi-step processes. Too often, teachers simplify until they require no HOTS at all.
I took several pictures, and will post them on the school web page. Kids always like to see themselves immortalized online.
