![]() We have made an atomic measurement.' The difference between a solid and liquid is not just the change in molecular. If your students are new to constructing claims with evidence (and reasoning when ready), lead them through the process.Ĭlaim: We can use information about matter’s shape to determine its physical state. So, d 4 x 10 -10 m and we have found the ‘diameter’ of a single molecule of air (An atom, or diatomic molecule, is probably half that size.) It is a rough guess but it is a good estimate it is the right order of magnitude. Record whether the item is a solid, liquid, or gas.Ĭhat: Which matter is a solid? What do you notice about their shape?Ĭhat: Which matter is a liquid? What do you notice about their shape?Ĭhat: Which matter is a gas? What do you notice about their shape? Then classify the matter as solid, liquid, or gas. This experiment will demonstrate how cooling water vapor can turn into liquid water. students that some books and other resources may define states of matter more simply in the following way.
