Comments about Including the Crosscutting Concept
In the lesson description, the author includes the following statement but I didn't feel it was made explicit. The Crosscutting Concept for this lesson is “Natural objects exist from the very small to the immensely large” so a focus will be placed on matter in the gaseous state and how it is detected.The Crosscutting Concept needs to be pointed out explicitly to students. For example, when students are using the interactive simulations of models, the teacher should point out the relationship between the small particles of matter and a rock ( or the size of the particles that make up a rock), that is the arrangement of the particles that explains the observable properties of the rock. The student should be able to use the cross-cutting concept as part of their explanation of the science concept. Student should be confident in their understanding that matter can be very large or very small, visible and invisible.
