Physics Labs At Home

I've made several posts on various virtual experiments that may be done in conjunction with the standard physics courses. While many of these are adequate, nothing beats an actual, physical experiment that requires actual observation and measurement in person.

This paper lists a few experiments that a student may be able to do at home using items that a student may find at home. Since almost everyone having smart phones, there are certainly many activities that can be done using such devices. I've asked my students to use their smartphones to install sky-viewing app to be able to track planets, stars, and other celestial bodies. We have also used various apps that made used of the accelerometer in the phone to measure acceleration. I also have an app called "Gauges" (iOS) that allows you to use your smartphone to be an altimeter, speedometer, barometer, accelerometer (of course), magnometer, and to measure sound level and luminance. I am in the middle of designing a few "in class" (and now, it is "at home") activities using these capabilities.

While virtual experiment is fine for the present unusual situation, I still believe that this is not the same as actually doing the measurement itself and physically performing the experiment. So I'm trying to find activities that a student may be able to do him/herself, or in collaboration with another student if he/she does not have all the necessary equipment. I want to incorporate this as part of the lesson rather than an actual "experiment", so that the student can see the phenomenon that they are studying or about to study.

Have you designed simple at-home physics experiments for your students?
