When Colin Cuthbert asked on facebook if anyone could recommend a simulation of the alpha, beta and gamma experiment it reminded me of something I saw many years ago. It was a remote lab rather than a simulated one, in other words you collected data from a real experiment that was being carried out in someone's lab. I tried various searches and eventually found this https://www.ises.info/index.php/en. I think this is fantastic. They are real experiments carried out automatically in real time, students can take repeated measurements to generate uncertainties which solves the frequently asked question how do you estimate uncertainties in a virtual lab? I have only just discovered this but intend to produce some worksheets to go with them over the next couple of weeks. The exact Lab Colin asked about isn't possible but something similar is here . In the video clip below it is actually me controlling the experiment, so here is the big question, what happens when more than one student wants to take measurements at the same time? Maybe they join a queue, maybe it crashes. I have written to the team asking this question but in the meantime I have the start of an idea. Something like crowd sourcing in reverse. The experiment is scheduled to run every hour and you sign up for a slot, then the bit I'm not sure how to handle, participants put in their bids for measurements they wish to take and then based on the requests measurements are made. Obviously if there are 1000 experimenters they can't all have their measurements done live but if the options are narrowed down a bit they might get some live data then the rest given from historic data. Actually it's not so bad, in this radioactivity experiment the total recording time for all options is only 15 minutes, so everyone could get their data live. When particular student's data was being recorded they would be notified. Maybe students vote for each variable or there is some sort of competition to elect a leader who carries out the experiment and everyone else watches. The neat thing about this is that you actually control the experiment, that aspect might be lost if the measurements are automated. Interesting times.
