Students test white vinegar (5% acetic acid) against five suggested stones: limestone, marble, chalk, granite, and quartz. The results table asks them to note whether bubbling occurred, rate reaction strength on a four-point scale from none to strong, describe surface changes, and add optional drawings. A hypothesis section before the experiment and a conclusion section after it push students to reason before and after, not just observe. Suited for grades 4-7, this lab sheet works well within an earth science or geology unit.

The effect of acid on different types of stone connects directly to real-world topics like acid rain, cave formation, and building material selection, making it a strong anchor for a broader unit study on rocks and minerals or weathering. Your homeschooler completes the sheet from question through conclusion in a single sitting, and the Think and Extend section prompts them to move from observation toward explanation, a skill that carries across every science discipline.
