Names of Group Members: Lab 2 Assignment: Chemistry Foundations Part 1 Hypothesis A: Oil and water don’t mix because water is polar and oil is non-polar. vs. Hypothesis B: Oil and water don’t mix because they have different densities 1.) Elaborate on the proposed explanation (the how/why ) you wrote previously (you may already be satisfied with your explanation – if so just copy it down here). REMEMBER : Assume your audience is intelligent, but not a scientist/science major, SO define scientific terms using simple language within your answer. (10pts) A.) substances with different polarities (polar and non-polar) don’t mix because (your how/why or mechanism )… B.) substances with different densities don’t mix because (your how/why or mechanism )… A (different polarities) B (different densities) (limit 600 characters) (limit 600 characters) 2a.) Choose two experiments from the Experiments Protocol Sheet ( write down the two experiments that you chose in the space below) that you think will help you decide which hypothesis is the stronger explanation for why oil and water don’t mix : 2b.) Which experiments did you choose: (5pts) (limit 600 characters) DO NOT do the experiments yet! You need to make predictions in the table below about what you expect the experiments to tell you before you jump into doing them.
