In Mr. Bullock’s eighth-grade science class, students engaged in a hands-on density laboratory experiment using various common liquids—oil, rubbing alcohol, dish soap, and maple syrup. They began by predicting how these substances would interact and settle when combined. To test their hypotheses, students measured 50 milliliters of each liquid and calculated its density to determine the correct stacking order.
This hands-on lesson enabled students to visualize how substances layer by mass and volume, reinforcing foundational concepts about physical properties while connecting these ideas to the Earth’s layered composition.
