I’m not sure if you are f2f or virtual. But I feel like a good lab would be to give each student a nail (steel) and see who can get it to rust first (or the most). The winner would have most certainly used salt with water/air to get the metal to react.
This year I had my students naked homemade handwarjers. We used iron filings, calcium chloride salt, and water marbles (the water absorbing polymer beads). You can find the beads at craft store and online, they are super inexpensive. It's a great exothermic reaction, addresses redox concepts, rates of reactions etc.... I also show them the dispisable hand warmers that are sold in the outdoorss section of big box stores. I also have the instant cold packs from the nurses office. I am able to show them these products and explain the basic chemistry that allows them to be hot or cold.
