Since I've been teaching phys/chem changes, I could probably make use of the data sheet, but you might want to add directions that are a little more clear about how to set up the experiment for teachers looking for a quick lab activity. What I downloaded does not have directions for setting up the lab, just your thoughts on the before/after sheet, materials needed and the data collection sheet wi pictures. It doesn't expand on the actual activities themselves. Just a friendly suggestion. Thank you for your materials! Keep up the awesome work!

Thank you, sounds like a brilliant plan. This was one of my first postings on here. Thanks for the feedback, it helps improve future materials. You Rock!

Bonnie, I just went back in and fixed the setup instructions. Take a look, let me know what you think, are they clearer? Thanks again.

Was there any other directions, such as tasks cards for the stations or demos? Like, was the steel wool soaked in water?

Hi, yes the first page gives the teacher instructions.
If you make copies of the before and after placemats for each station you can have them already set up.
Steel wool is best soaked for 24 hours in distilled water for the after oxidized look, then the crushed can, you can have enough cans for all kids to do the after or just have one sitting there for speed observations. I hope this covers your questions.
If you feel a task card is necessary you can write it under your placemat so that they know to look at the before and then the after and identify if it is a chemical or physical change.
The student observation sheet page 3 has place for students to check if it is a chemical/physical change and then a section to provide observations and proof of their conclusion.

Let me know if you need anything more... thought to self, maybe I will create those task cards you speak of! Thank you for selecting my materials.
