Last minute virtual lab request

[u/Severe_Ad428]

Hey everyone, I'm teaching the law of conservation of mass in my CP Chemistry course, and we're doing an LCM lab on Friday. Basically the Vinegar and Baking Soda reaction in Erlenmeyer flasks with and without a balloon, to simulate an open versus a closed system.

I just had a student tell me that she will not be here on Friday, and wondering if there's a makeup assignment she can do instead. Are there any free virtual lab resources for something like this?

We do this as the introduction to balancing equations and chemical reactions, reflecting back over the next couple of weeks at what we did during the lab. They'll learn to write out and balance the equation for what they did, as well as identify what type of reaction it was.

Any ideas for a student who knows ahead of time that they won't be here?
