Direct Detection of Dark Matter with LENS: A New Directionally Sensitive Low Energy WIMP Detector
Build a simple cosmic ray detector that can be built by high school teachers
Build a Fuse Monitor
Make your own thermistor and pressure sensor.
Demonstrate that If the number of detection zones can be larger than the number of sensors, then there is a mathematical algorithm to calculate the maximum number of detection zones given a number of sensors.
