M1. Popping Corks | Introductory students often think that pressure is a force. Many textbooks play into this misconception by giving examples in which the force that creates the pressure is in the same direction as a force one infers from the pressure. This problem raises the issue effectively and helps students think about what it means to have a (non-directional) pressure. (Their success in memorizing a proportionality pattern for the standard Pascal's law example doesn't mean that they understand the non-directionality of pressure.) | EFR | This demo could be difficult to set up. The holes, corks, and amount that the corks have been pushed in have to be very similar. |
M2. Blood Flow 1 | This and the next problem help students learn to differentiate flux and speed. | From the ConcepTest collection in Mazur's Peer Instruction | |
M3. Blood Flow 2 | This and the previous problem help students learn to differentiate flux and speed. | From the ConcepTest collection in Mazur's Peer Instruction | |
M4. Bernoulli | This one introduces students to the surprising effects of Bernoulli's principle. This demo can be done individually by the students in their seats even in a large lecture class. (After they have made and discussed their predictions, of course!) | EFR | in-seat demo |
