This is a Chemical Weathering STEM experiment we do in my Earth Science Classroom every year. It is not too difficult to set up and the children really enjoy doing it. I usually do it at the end of the unit as a culminating activity to review the material we have already learned. I have uploaded the following material to help in the experiment.
2 writing prompts.
The teacher instructions include everything you need as well as HOTS (higher order thinking questions to ask during the experiment. The student instructions include questions that coincide with every step of the experiment. The writings prompts require Higher order thinking as well and are a great way to extend the activity to the next day.
