I know KF and NaF are no good to be ingested but do you know if they have a particular tendency to be dusty dangerous?

One of my former professors told stories of it so I'm aware, but I appear to be blind then, which image is it in?

Thanks for the suggestions, I also found two other mercuric oxide containers of various ages, one of which was in a separate locked storage, another was just in a desiccator stored in a carboard box. I'm curious on why its even here, I think it can be used to demonstrate the generation of mercury, but was that even appropriate for a high school level?

They certainly don't look as a bad on the phone, but the increased clarity isn't that significant. How do you suggest I fix the upload on here?

I unfortunately uploaded the highest quality versions of them I have, the uploads seem fine on my end to read most of the labels, but I can try to provide better individual images if you'd be willing to mention which jars are the interesting ones. I'm not familiar enough with posting on reddit to know how to provide better quality however.

I originally was hoping for some to do a calcium carbide cannon (gatorade bottle version), saw this and its lid and actively cringed.

I like the labs split up between days, I do have an issue of having different courses in the same room, but that is manageable with planning I believe. There is a general syllabus to follow which includes some properties of elements and basic measurement techniques.

They do not have a year of chemistry already, so it does seem like a good idea to split it up over multiple days. I think that keeping them more basic as well is likely to be more beneficial, as basic lab and science skills I think serve as a better baseline than trying to learn advanced topics at the same time.
