How to ensure that experimental work can continue in such lock down conditions too?
Here is a paper written by Prof. K V Sane, with whom I had an opportunity to work with, during 1989-1992. The solution is, what he calls a 'Teaching Instrument'.
You may have already realized how the specifications of several instruments in electronics labs are way above their actually utilization. A 1GSPS/100 MHz DSO commonly found in electronics labs, hardly ever gets used beyond 1 MHz.

Today, the cheapest 3-1/2 digit DMM sells for less than Rs. 100. It is
not impossible to imagine a 10MHz BW DSO front end connected to your
laptop (for the display) for Rs. 250. Thus, it is quite possible to imagine a 'Lab in a Box' with a set of components etc, all for less than Rs. 1000 that may be quite sufficient for conducting experiments at home during lockdown conditions.
Getting a student to build such a 'teaching instruments' will generate an additional benefit of student involvement, skills in soldering, system design etc, which are currently sorely lacking.
