Air is our many familiar example of the state of issue we speak to gas. Us live immersed in it and also depend on it to continue to be alive. It"s also invisible, not an especially tangible, and also can be challenging to investigate. But, favor solids and also liquids, waiting is matter. It has actually weight (more 보다 we might imagine), it takes increase space, and it is created of particles too small and too spread out apart come see. Air, a mixture the gases, share properties v water vapor, the gaseous type of water the is component of air. Knowledge air help us recognize water vapor.
Formative Assessment
Can your students use data to reason that wait is matter?

Can your students use data to reason that air is matter?
Notebook entries contain evidence the students have the right to use their observational data to make claims that waiting takes up room and has weight and is, therefore, matter.
You are watching: What type of matter is air
Annotated illustration of syringes
walk the drawing present that wait is constant from one syringe, with the connecting tube, to the other syringe?Does the annotation suggest the college student understands that that if you take away room for waiting in one syringe, the air needs to go in other places and, therefore, creates this room by pushing on the plunger of the 2nd syringe?Annotated drawing of inflated balloon
walk the student explain that that as soon as the balloon with extr air pushes the balance pan down, this is proof there an increase in weight the must have come indigenous the added air?Next steps could be a discussion of experience from everyday life the provide comparable evidence that air take away up room and has weight. For example, placing air in a tires pushes the tires out as the air fills the room and boosts the weight.
Students" investigations of solids and also liquids detailed evidence the these materials have actually weight and take up space and are for this reason matter. Currently students seek proof that air (a gas) has weight and takes up an are and is additionally mattter. This examination is the very first in a succession of 4 in i m sorry students inspection the nature of air. In spite of our gift able come move openly through air, students establish that wait takes up room as lock manipulate a device of combination syringes. Through a convincing balloon demonstration, it is also established that air has weight.
By the finish of this investigation students will have evidence that waiting takes up space, has actually weight, and, therefore, is matter. Students will certainly be presented to the idea that air is composed of corpuscle too small and too spread apart come see.
