| 1A20.10 | Gaussian curve marble board | 1A20.10 | |
| 1A20.10 | Gaussian collision board | A-47 | Balls roll down a nail board into parallel chutes forming a probability curve similar to the distribution of molecular velocities. |
| 1A20.10 | Gaussian curve | Disc 16-12 | A commercial device for the overhead projector where ball bearings roll through an array of nails into parallel chutes. |
| 1A20.20 | coin flip | PIRA 1000 | |
| 1A20.20 | coin flips | 1A20.20 | |
| 1A20.25 | dice | PIRA 1000 | |
| 1A20.25 | dice | 1A20.25 | |
| 1A20.31 | contact time measurement | AJP 43(8),732 | Measure contact time of two hammers being struck together. A pulse generator is gated to a pulse counter while the hammers are in contact. Frequency of the pulse generator can be changed to vary accuracy. |
| 1A20.41 | vernier calipers | 6-1 | Use commercial large scale verniers to show how they work. Also mentions large coordinate systems. |
| 1A20.41 | vernier calipers, etc | M-1b | Demonstration versions of the micrometer and vernier calipers. |
| 1A20.42 | vernier scale, slide rule for OH | M-1c | A slide rule and vernier scale made of clear plastic for use on the overhead projector. |
| 1A20.50 | weight judgment | PIRA 1000 | |
| 1A20.50 | wood and brass blocks | M-2 | A small heavy weight and a slightly lighter large wood block are passed around the class. |
| 1A20.51 | lead ping pong ball and foam chunk | 6-2.5 | Students judge weight of a white lead filled ping pong ball and a chunk of black foam. |
| 1A20.55 | statistics on OH | 6-1.1 | Transparent Lucite probability board for the OH projector. Construction details in the Appendix, p. 533. |
| 1A20.60 | reaction time | PIRA 1000 | |
| 1A20.60 | reaction time | 1A20.60 | Cover 3/4 of a stop clock face. Push the stop button when the hand shows. |
| 1A20.60 | reaction time | Mb-1a | A large stop clock is covered by a disc with one quadrant cut out. Stop the clock as soon as you see the hand emerge. |
| 1A20.60 | reaction time | 6-2.6.1 | Same as Mb-1a. |
