You did the experiment perfectly. You used the right formulas. So why is your final answer "wrong?" Welcome to the assumption trap. In this real-world case study, we calculate the mass of air inside of a ping-pong ball. It seems like simple volume and density calculations, but hidden within the math are a half-dozen assumptions that could ruin your data.
Challenge yourself: Watch the data collection and see if you can spot 3 major assumptions before I reveal them at 2:50. This is the "hidden" skill that separates an 'A' student from the rest.
