Question: Ask students if they can suggest a way to lift a pile of books using only their breath. ch_color_bg = "FFFFFF"; Remember (Answer: Engineers need to determine how much pressure air exerts so they can design filtration systems that are large enough for all the air to flow through without exerting so much pressure that it breaks the system. A model showing that gases are made from matter particles that are too small to see and are moving freely around in space can explain many observations, including the inflation and shape of a balloon and the effects of air on larger particles or objects. 6 - ch_height = "auto"; Ask the students if there is anything in them.
